An anonymous reader quotes a report from the New York Times: The Federal Trade Commission on Wednesday proposed sweeping changes to bolster the key federal rule that has protected children's privacy online, in one of the most significant attempts by the U.S. government to strengthen consumer privacy in more than a decade. The changes are intended to fortify the rules underlying the Children's Online Privacy Protection Act of 1998, a law that restricts the online tracking of youngsters by services like social media apps, video game platforms, toy retailers and digital advertising networks. Regulators said the moves would "shift the burden" of online safety from parents to apps and other digital services while curbing how platforms may use and monetize children's data.

The proposed changes would require certain online services to turn off targeted advertising by default for children under 13. They would prohibit the online services from using personal details like a child's cellphone number to induce youngsters to stay on their platforms longer. That means online services would no longer be able to use personal data to bombard young children with push notifications. The proposed updates would also strengthen security requirements for online services that collect children's data as well as limit the length of time online services could keep that information. And they would limit the collection of student data by learning apps and other educational-tech providers, by allowing schools to consent to the collection of children's personal details only for educational purposes, not commercial purposes. [...]

The F.T.C. began reviewing the children's privacy rule in 2019, receiving more than 175,000 comments from tech and advertising industry trade groups, video content developers, consumer advocacy groups and members of Congress. The resulting proposal (PDF) runs more than 150 pages. Proposed changes include narrowing an exception that allows online services to collect persistent identification codes for children for certain internal operations, like product improvement, consumer personalization or fraud prevention, without parental consent. The proposed changes would prohibit online operators from employing such user-tracking codes to maximize the amount of time children spend on their platforms. That means online services would not be able to use techniques like sending mobile phone notifications "to prompt the child to engage with the site or service, without verifiable parental consent," according to the proposal. How online services would comply with the changes is not yet known. Members of the public have 60 days to comment on the proposals, after which the commission will vote.

Most companies are not ready to deploy generative AI at scale because they lack strong data infrastructure or the controls needed to make sure the technology is used safely, according to the chief executive of the consultancy Accenture. From a report: The most hyped technology of 2023 is in an experimental phase at most companies and macroeconomic uncertainty is holding back IT spending generally, Julie Sweet told the Financial Times in an interview ahead of the company publishing quarterly results on Tuesday. Accenture reported another big jump in revenues from generative AI projects in the three months to November 30, with $450mn in bookings compared with $300mn over the previous six months. But they remain small relative to group sales of $64bn annually.

Corporate executives are keen to deploy the technology to understand data across their organisation better or to automate more customer service, Sweet said. "The thing that is going to hold it back, though, isâ...âmost companies do not have mature data capabilities and if you can't use your data, you can't use AI. That said, in three to five years we expect this to be a big part of our business." Accenture and other consulting groups have boasted of multibillion-dollar investments in generative AI, including hiring and training staff, in the hope of a windfall from deploying the technology to clients across the world.

Sweet said executives were being âoeprudentâ in rolling out the technology, amid concerns over how to protect proprietary information and customer data and questions about the accuracy of outputs from generative AI models. "We are still at the stage where most CEOs, asked if there is someone in their organisation who can tell them where AI is being used, what the risks are and how they're being mitigated, the answer is still 'no.'"

A worrying number of UK authorities are still unaware of the impending switch-off of 2G and 3G mobile networks, according to Local Government Association (LGA) figures. From a report: While 38 percent of respondents were fully aware, 27 percent were only partially aware, and 7 percent had no idea at all that the axe would be falling by 2033 at the latest. The numbers worsened when the researchers spoke to respondents in senior management. Almost half (48 percent) were "partially aware" the UK's 2G and 3G mobile networks were due to be switched off and 14 percent were not at all aware.

The actual switch-off will happen over the next few years. UK mobile operators have told government they do not intend to offer 2G and 3G mobile networks past 2033 at the latest, and there is a high likelihood that some networks will be shut down earlier. The UK government said it welcomes plans to end services ahead of time. Vodafone, for example, intends to pull the plug on 3G once and for all from January 2024. Although most consumers, with their 4G and 5G devices, will likely be unaware of the end when it comes, the same cannot be said of local authorities. According to the survey, almost two-thirds of respondents (63 percent) reported that their authority was still using devices or services reliant on 2G and 3G networks.

samleecole writes: The LAION-5B machine learning dataset used by Google, Stable Diffusion, and other major AI products has been removed by the organization that created it after a Stanford study found that it contained 3,226 suspected instances of child sexual abuse material, 1,008 of which were externally validated.

LAION told 404 Media on Tuesday that out of "an abundance of caution," it was taking down its datasets temporarily "to ensure they are safe before republishing them." According to a new study by the Stanford Internet Observatory shared with 404 Media ahead of publication, the researchers found the suspected instances of CSAM through a combination of perceptual and cryptographic hash-based detection and analysis of the images themselves.

The European Union on Wednesday added three adult content companies - Pornhub, Stripchat and XVideos - to its list of firms subject to stringent regulations under new online content rules. From a report: The new rules, known as the Digital Services Act (DSA), require companies to conduct risk management, undergo external and independent auditing, and share data with authorities and researchers. In April, the EU designated five Alphabet subsidiaries, two Meta Platforms units, two Microsoft businesses, X and Alibaba's AliExpress among 19 companies under the rules. Such designated companies will have to do more to tackle disinformation, give more protection and choice to users and ensure stronger protection for children or risk fines of as much as 6% of their global turnover. "Pornhub, Stripchat and XVideos meet the user thresholds to fall under stricter #DSA obligations," the bloc's industry chief Thierry Breton said. "Creating a safer online environment for our children is an enforcement priority under the DSA."

"EVs mandates are coming to Canada whether you like it or not," writes Slashdot reader Major_Disorder, sharing a report from the Canadian Broadcasting Corporation. "Here is what my Canadian brothers and sisters need to know." From the report: New regulations being published this week by Environment Minister Steven Guilbeault will effectively end sales of new passenger vehicles powered only by gasoline or diesel in 2035. Guilbeault said the Electric Vehicle Availability Standard will encourage automakers to make more battery-powered cars and trucks available in Canada. "There's no mistaking it. We are at a tipping point," he said, noting sizable growth in EV sales in Canada and demand that has previously outstripped the available supply.

Automakers will have the next 12 years to phase out combustion engine cars, trucks and SUVs with a requirement to gradually increase the proportion of electric models they offer for sale each year. The electric-vehicle sales mandate regulations will be published later this week. They are setting up a system in which every automaker will have to show that a minimum percentage of vehicles they offer for sale are fully electric or longer-range plug-in hybrids. It will start with 20 per cent in 2026 and rise slightly to 23 per cent in 2027. After that, the share of EVs will begin to increase much faster, so that by 2028, 34 per cent of all vehicles sold will need to be electric -- 43 per cent by 2029 and 60 per cent by 2030. That number keeps rising until it hits 100 per cent in 2035.

Guilbeault said the government is working to revise the national building code to encourage the spread of charging stations. The updated code would ensure that residential buildings constructed after 2025 have the electrical capacity to accommodate the charging stations. [...] The policy will be regulated under the Canadian Environmental Protection Act and will issue credits to automakers for the EVs they sell. Generally, a fully electric model will generate one credit, with plug-in hybrids getting partial or full credit depending on how far they can go on a single charge. Manufacturers that sell more EVs than they need to meet each year's target can either bank those credits to meet their targets in future years, or sell them to companies that didn't sell enough. They can also cover up to 10 per cent of the credits they need each year by investing in public fast-charging stations. Every $20,000 spent on DC fast chargers that are operating before 2027 can earn the equivalent of one credit. Automakers that come up short for their sales requirements will be able to cover the difference by buying credits from others who exceed their targets, or by investing in charging stations. Automakers can start earning some credits toward their 2026 and 2027 targets over the next two years -- a bid by the government to encourage a faster transition.

An anonymous reader quotes a report from the BBC: A bill that mandates tech giants pay news outlets for their content has come into effect in Canada amid an ongoing dispute with Facebook and Instagram owner Meta over the law. Some have hailed it as a game-changer that sets out a permanent framework that will see a steady drip of funds from wealthy tech companies to Canada's struggling journalism industry. But it has also been met with resistance by Google and Meta -- the only two companies big enough to be encompassed by the law. In response, over the summer, Meta blocked access to news on Facebook and Instagram for Canadians. Google looked set to follow, but after months of talks, the federal government was able to negotiate a deal with the search giant as the company has agreed to pay Canadian news outlets $75 million annually.

No such agreement appears to be on the horizon with Meta, which has called the law "fundamentally flawed." If Meta is refusing to budge, so is the government. "We will continue to push Meta, that makes billions of dollars in profits, even though it is refusing to invest in the journalistic rigor and stability of the media," Prime Minister Justin Trudeau told reporters on Friday. According to a study by the Media Ecosystem Observatory, the views of Canadian news on Facebook dropped 90% after the company blocked access to news on the platform. Local news outlets have been hit particularly hard.

"The loss of journalism on Meta platforms represents a significant decline in the resiliency of the Canadian media ecosystem," said Taylor Owen, a researcher at McGill and the co-author of the study. He believes it also hurts Meta's brand in the long run, pointing to the fact that the Canada's federal government, as well as that of British Columbia, other municipalities and a handful of large Canadian corporations, have all pulled their advertising off Facebook and Instagram in retaliation.

Alphabet will pay $700 million and alter its Google Play policies to settle claims that the app store unlawfully dominates the Android mobile applications market, resolving antitrust complaints brought by attorneys general of about three dozen states and consumers. From a report: The deal disclosed in a court filing late Monday calls for tweaks to Google Play policies designed to reduce barriers to competition in the markets for app distribution and payment processing. The lawsuits that were grouped together in federal court in California had threatened billions of dollars in revenue generated by the sale and distribution of apps through Google Play. Google will also make a series of changes to its business practices as part of the settlement. In a blog post, the Android-maker said: Streamlining sideloading while prioritizing security: Unlike on iOS, Android users have the option to sideload apps, meaning they can download directly from a developer's website without going through an app store like Google Play. While we maintain it is critical to our safety efforts to inform users that sideloading on mobile could come with unique risks, as part of our settlement we will be further simplifying the sideloading process and updating the language that informs users about these potential risks of downloading apps directly from the web for the first time.
Expanding user choice billing to more people: App and game developers will be able to implement an alternative billing option alongside Google Play's billing system for their U.S. users who can then choose which option to use when making in-app purchases. We have been piloting user choice billing in the U.S. for over a year and will now expand this option further.
Expanding open communication on pricing: We have always given developers more ways to interact with their customers than iOS and other operating systems. For example, Google Play allows developers to communicate freely with their customers outside the app about subscription offers or lower-cost options available on a rival app store or the developer's website. This openness has spurred competition and benefited consumers and developers. As part of user choice billing, which we're expanding with today's settlement announcement, developers are also able to show different pricing options within the app when a user makes a digital purchase.

An anonymous reader quotes a report from Reuters: IBM said on Monday that it would buy Software AG's enterprise integration platforms for 2.13 billion euros ($2.33 billion) to bolster its artificial intelligence and hybrid cloud offerings. IBM will acquire Software AG's StreamSets and webMethods platforms with available cash on hand, it said. The two units formed Software AG's so-called "Super Ipaas" business, which was launched in October.

The platforms provide application integration, application programming interface (API) management, and data integration among other uses. Software AG is majority owned by private equity firm Silver Lake, which currently owns 93.3% of shares in the German software company, following a takeover pursuit spanning several months. That deal valued the whole business at 2.6 billion euros ($2.84 billion). The transaction is subject to regulatory approvals and is expected to be completed in the second quarter of 2024. "The opportunity to bring the StreamSets and webMethods teams together with IBM to innovate in building the future of hybrid cloud and next-generation AI solutions for the enterprise is uniquely compelling," Christian Lucas, chairman of the supervisory board of Software AG said in a statement.

Firefox 121 has arrived with Wayland support to be used by default on modern Linux desktops. Phoronix's Michael Larabel writes: Some Linux distributions and package builds have been using the native Wayland path for a while but now it's great to see the upstream builds make this default change as we get ready to embark on the 2024 Linux desktop. With my testing of Firefox 121 on Wayland, it's been working out well. X.Org/X11 support remains in place for those not using a Wayland-based desktop environment.

Firefox 121 also adds Voice Control command support on macOS, adds an option to always force-underline links within websites, Firefox now includes a floating button to help in creation within PDFs, various CSS feature additions, and other developer enhancements. Firefox 121 also now supports tail call elimination in WebAssembly for enhancing support for functional languages. You can download Firefox 121 via archive.mozilla.org.

Ernesto Van der Sar reports via TorrentFreak: Internet Archive has filed its opening brief in its appeal of a court ruling which found its digital lending program copyright-infringing. The Archive believes the decision should be reversed on the grounds that its lending activities amount to fair use. Founder Brewster Kahle believes the legal battle is vital for the future of all libraries in the United States and around the world. [ "This lawsuit is about more than the Internet Archive; it is about the role of all libraries in our digital age," says IA founder Brewster Kahle. "This lawsuit is an attack on a well-established practice used by hundreds of libraries to provide public access to their collections. The disastrous lower court decision in this case holds implications far beyond our organization, shaping the future of all libraries in the United States and unfortunately, around the world."]

Whether IA has a fair use defense depends on how the four relevant factors are weighed. According to the lower court, these favor the publishers but the library vehemently disagrees. On the contrary, it believes that its service promotes the creation and sharing of knowledge, which is a core purpose of copyright. "This Court should reverse and hold that IA's controlled digital lending is fair use. This practice, like traditional library lending, furthers copyright's goal of promoting public availability of knowledge without harming authors or publishers," the brief reads. A fair use analysis has to weigh the interests of both sides. The lower court did so, but IA argues that it reached the wrong conclusions, failing to properly account for the "tremendous public benefits" controlled digital lending offers.

One of the key fair use factors at stake is whether IA's lending program affects (i.e., threatens) the traditional ebook lending market. IA uses expert witnesses to argue that there's no financial harm and further argues that its service is substantially different from the ebook licensing market. IA offers access to digital copies of books, which is similar to licensed libraries. However, the non-profit organization argues that its lending program is not a substitute as it offers a fundamentally different service. "For example, libraries cannot use ebook licenses to build permanent collections. But they can use licensing to easily change the selection of ebooks they offer to adapt to changing interests," IA writes.

The licensing models make these libraries more flexible. However, they have to rely on the books offered by commercial aggregators and can't add these digital copies to their archives. "Controlled digital lending, by contrast, allows libraries to lend only books from their own permanent collections. They can preserve and lend older editions, maintaining an accurate historical record of books as they were printed. "They can also provide access that does not depend on what Publishers choose to make available. But libraries must own a copy of each book they lend, so they cannot easily swap one book for another when interest or trends change," IA adds. A copy of the Internet Archive's opening brief, filed at the Second Circuit Court of Appeals, is available here (pdf)

Ron Amadeo reports via Ars Technica: Stadia might be dead, but the controllers for Google's cloud-based gaming platform are still out there. With the service permanently offline, the proprietary Stadia Controller threatened to fill up landfills until Google devised a plan to convert them to generic Bluetooth devices that can work on almost anything. The app to open up the controller to other devices is a web service, which previously had a shutdown date of December 2023. That apparently isn't enough time to convert all these controllers, so the Stadia Controller Salvage operation will run for a whole additional year. X (formerly Twitter) user Wario64 was the first to spot the announcement, which says the online tool will continue running until December 31, 2024.

Flipboard, the social media magazine and news app, announced that it is starting to switch its user accounts to ActivityPub, a technology developed by the World Wide Web Consortium that makes social networks interoperable, "connecting everything to a single social graph and content-sharing system," reports The Verge. From the report: Right now, only 25 accounts have been federated with ActivityPub, but by March Flipboard says it plans to allow anyone on the platform to open their account to the fediverse and allow any Flipboard user to follow any fediverse account from within the Flipboard app. At that point, Flipboard will essentially be an ActivityPub-based platform like Mastodon or Pixelfed but with an interface designed for reading articles instead of bite-sized posts. It'll be the biggest thing in the fediverse -- at least until Threads shows up for real.

"Basically, we're in the process of replacing our whole social back-end with ActivityPub," says Flipboard CEO Mike McCue. "I think Flipboard is going to be the first mainstream consumer service that existed in a walled garden that switches over to ActivityPub."

Travel website Expedia wants to get people to start their travel search on its site with AI instead of using an external search engine. From a report: Expedia already uses AI for some customer service features and to help property owners describe their homes and hotels. The company hopes in the future that AI will help it recommend travel destinations to customers based on previous trips and bring more direct traffic to its site. It's a long-term plan to shift the balance of power on the web -- albeit one that's still in its earliest stages for the company.

Rajesh Naidu, chief architect and head of data management at Expedia, says the goal is to get users started on their trips in one place. Expedia hopes to produce recommendations trained with its library of flight and hotel information and informed by users' travel preferences. "By being able to train large language models on our data, this rich 70 petabytes' worth of data we've gathered over the years, we can eventually recommend places to go and stay and do and continue to refine and personalize that," Naidu tells The Verge in an interview. According to Naidu, when people plan trips, they often start by going to a search engine to look for a destination. Only then do they visit services like Expedia to start booking travel and accommodation. There's nothing inherently wrong with going to Google and typing "best vacation that isn't cold and not that far from New York," but Naidu believes there's value in streamlining the travel planning process even more.

The giants of the consulting world face an unusual quandary this year: many of them are in the process of dismissing hundreds of staffers even after they hired thousands of college graduates to deal with new demand. Now, one of the biggest of them all is looking to AI to change that. From a report: Deloitte is using AI to evaluate existing staffers' skills and map out plans that would shift employees away from quieter parts of the business and into roles that are more in demand. It's part of a broader bet by the professional services firm that the technology will allow it to moderate hiring growth over time.

The moves come after Deloitte added 130,000 staffers this year. But in the midst of those hirings, though, the firm warned thousands of staffers in the US and UK that their jobs were at risk of becoming redundant after the company was forced to restructure certain areas of the business in response to a slowdown in demand. "It is obviously a great objective to be able to avoid large swings of hirings and layoffs," said Stevan Rolls, global chief talent officer at Deloitte. "You could always be more efficient and effective about finding the right people."

"For the past two weeks, I've been using a new camera to secretly snap photos and record videos of strangers in parks, on trains, inside stores and at restaurants," writes a reporter for the New York Times. They were testing the recently released $300 Ray-Ban Meta glasses — "I promise it was all in the name of journalism" — which also includes microphones (and speakers, for listening to audio).

They call the device "part of a broader ambition in Silicon Valley to shift computing away from smartphone and computer screens and toward our faces." Meta, Apple and Magic Leap have all been hyping mixed-reality headsets that use cameras to allow their software to interact with objects in the real world. On Tuesday, Zuckerberg posted a video on Instagram demonstrating how the smart glasses could use AI to scan a shirt and help him pick out a pair of matching pants. Wearable face computers, the companies say, could eventually change the way we live and work... While I was impressed with the comfortable, stylish design of the glasses, I felt bothered by the implications for our privacy...

To inform people that they are being photographed, the Ray-Ban Meta glasses include a tiny LED light embedded in the right frame to indicate when the device is recording. When a photo is snapped, it flashes momentarily. When a video is recording, it is continuously illuminated. As I shot 200 photos and videos with the glasses in public, including on BART trains, on hiking trails and in parks, no one looked at the LED light or confronted me about it. And why would they? It would be rude to comment on a stranger's glasses, let alone stare at them... [A] Meta spokesperson, said the company took privacy seriously and designed safety measures, including a tamper-detection technology, to prevent users from covering up the LED light with tape.
But another concern was how smart glasses might impact our ability to focus: Even when I wasn't using any of the features, I felt distracted while wearing them... I had problems concentrating while driving a car or riding a scooter. Not only was I constantly bracing myself for opportunities to shoot video, but the reflection from other car headlights emitted a harsh, blue strobe effect through the eyeglass lenses. Meta's safety manual for the Ray-Bans advises people to stay focused while driving, but it doesn't mention the glare from headlights. While doing work on a computer, the glasses felt unnecessary because there was rarely anything worth photographing at my desk, but a part of my mind constantly felt preoccupied by the possibility...

Ben Long, a photography teacher in San Francisco, said he was skeptical about the premise of the Meta glasses helping people remain present. "If you've got the camera with you, you're immediately not in the moment," he said. "Now you're wondering, Is this something I can present and record?"
The reporter admits they'll fondly cherish its photos of their dog [including in the original article], but "the main problem is that the glasses don't do much we can't already do with phones... while these types of moments are truly precious, that benefit probably won't be enough to convince a vast majority of consumers to buy smart glasses and wear them regularly, given the potential costs of lost privacy and distraction."

Forbes recently published this article by author/speaker Nina Xiang, who reports that Huawei is pushing forward with "an amibitious plan to dethrone Android." Hundreds of technical experts from many of China's biggest state-owned and private companies, including the Industrial and Commercial Bank of China (ICBC), China Telecom, Meituan, and Baidu, all gathered in Beijing last month. The purpose behind the meeting was for their staff to receive training so they could be certified as developers on Huawei's Harmony Operation System (OS).

While most observers were looking the other way, Huawei has been quietly building an independent Chinese operating system that isn't subject to U.S. sanctions. In the four years after the telecom giant was banned from using Google apps, the Shenzhen-based company has been making significant strides toward achieving its long-term goal: To dethrone Android and make its HarmonyOS the default operating system in China.

Looking at the data for smartphone sales in China shows that HarmonyOS had the third-largest share with 10% in the second quarter of 2023, thanks to a strong resurgence in sales of Huawei smartphones. Although it's still well below Android's dominant 72%, it's not far from iOS's 17%... Huawei already says more than 700 million devices (including phones, smart devices, computers, and others) were equipped with HarmonyOS as of August this year, with over 2.2 million developers actively building within the ecosystem...

A key moment will come next year, when Huawei says HarmonyOS will no longer be compatible with Android apps.

Earlier this week Google Maps stopped storing user location histories in the cloud. But why did Google make this move? Bloomberg reports that it was "so that the company no longer has access to users' individual location histories, cutting off its ability to respond to law enforcement warrants that ask for data on everyone who was in the vicinity of a crime." The company said Thursday that for users who have it enabled, location data will soon be saved directly on users' devices, blocking Google from being able to see it, and, by extension, blocking law enforcement from being able to demand that information from Google. "Your location information is personal," said Marlo McGriff, director of product for Google Maps, in the blog post. "We're committed to keeping it safe, private and in your control."

The change comes three months after a Bloomberg Businessweek investigation that found police across the US were increasingly using warrants to obtain location and search data from Google, even for nonviolent cases, and even for people who had nothing to do with the crime. "It's well past time," said Jennifer Lynch, the general counsel at the Electronic Frontier Foundation, a San Francisco-based nonprofit that defends digital civil liberties. "We've been calling on Google to make these changes for years, and I think it's fantastic for Google users, because it means that they can take advantage of features like location history without having to fear that the police will get access to all of that data."

Google said it would roll out the changes gradually through the next year on its own Android and Apple Inc.'s iOS mobile operating systems, and that users will receive a notification when the update comes to their account. The company won't be able to respond to new geofence warrants once the update is complete, including for people who choose to save encrypted backups of their location data to the cloud.
The EFF general counsel also pointed out to Bloomberg that "nobody else has been storing and collecting data in the same way as Google." (Apple, for example, is technically unable to provide the same data to police.)

An anonymous reader shared this report from the Verge: On Friday, two days after Threads finally started publicly testing ActivityPub integration, Instagram head Adam Mosseri shared a thread on Threads detailing the company's plans for its continued integration with the fediverse. Right now, it's possible to follow a few Threads accounts (including Mosseri's) from other platforms, but Meta has much bigger plans for Threads interoperability that Mosseri says will take "the better part of a year" to realize...

Mosseri says that the Threads team wants to make it so the option to follow a Threads account on other platforms is available to "all public accounts on Threads, not just a handful of testers." The Threads team wants to let replies from other platforms show up inside of Threads.
According to the article, Threads is also planning to support the ability to follow non-Threads fediverse accounts — and even taking that openness in the other direction.

"Eventually, it should also be possible to enable creators to leave Threads and take their followers with them to another app / server," Mosseri writes.

Flipboard and Wordpress already allow ActivityPub integration, according to NBC News. They estimate there's 11 million users of the Fediverse now, "the vast majority of them on Mastodon."

"Unlike automobiles, jumbo jets cannot run on batteries," notes the Washington Post.

So Friday the White unveiled a plan for "subsidizing sustainable aviation fuels" — which could also give the U.S. a leg up in a brand new industry: Senior White House officials said the program would make the airline industry cleaner while bringing prosperity to rural America. But environmental groups and some scientists expressed reservations about the plan, which would award subsidies based on a scientific model that has previously been used to justify incentives for corn-based ethanol. Studies have found the gasoline additive is exacerbating climate change.

The new tax credits, created through President Biden's signature climate law, are meant to spur production of jet fuels that create no more than half the emissions of the petroleum-based product. Each gallon of such fuel qualifies for a tax credit up to $1.75 per gallon. "The concern is they will end up subsidizing fuels that take an enormous amount of land to produce," said Tim Searchinger, a senior research scholar at Princeton University... Administration officials said on a call with reporters Thursday that they are carefully weighing such concerns. Agencies are in the process of updating the scientific model for gauging climate friendliness of jet fuels, they said, and it will be revised to factor in the emissions impact of cropland converted from food to fuel production. Federal agencies plan to complete their revisions by March 1.

"The sustainable aviation fuel industry is a potential 36 billion gallon industry that for all intents and purposes is just getting started," Agriculture Secretary Tom Vilsack said on the call. "This is a big, big deal."
