The world needs to reduce carbon levels, and one way is through a carbon tax, a strategy the U.S. has been debating for decades.   

With urgent calls to lower greenhouse gas emissions globally, putting a price on carbon was one of the major points of discussion among world leaders at the COP26 conference in Glasgow earlier this month. Consensus on a global carbon price is growing, according to Lord Greg Barker, executive chairman at EN+ and co-chair of the Carbon Pricing Leadership Coalition. 

“We need countries to come together to agree on international standards in order to make that big shift to the low carbon economy,” Barker told CNBC in an interview from COP26 last week. ”It would be much better for the world if there was a common carbon price.” 

As of now, Barker says there are 69 countries with a carbon price ranging from $1 to $139 per metric ton. The U.S. is not one of them.  

Barker told CNBC most economists agree that carbon pricing is the most effective tool there is to transition to a low carbon economy. Carbon pricing shifts the liability for the consequences of climate change to the polluters who are responsible, according to the World Bank.

The Biden administration has outlined $555 billion in spending to confront climate change, though the plan does not address carbon pricing. The bill does include a proposed methane fee incentivizing oil and gas companies to reduce their methane emissions. 

A policy to apply a carbon tax was considered as a “plan B” during negotiations over the current climate package, according to the New York Times, after Biden’s clean electricity program was cut from the spending bill last month.

If the U.S. administration can’t get behind the rest of the world on carbon pricing, there are other ways to follow through with the initiative, says Barker, such as regulations, taxes, and emissions trading. 

The U.S. has considered carbon import fees and emissions trading that would apply to carbon-intensive products imported to the country. “But carbon import fees only make sense if you have some kind of domestic U.S. carbon policy,” says Richard Newell, president of Resources for the Future, a nonpartisan energy and environment research organization.   

He thinks a price on carbon ultimately is achievable as part of U.S. policy as the world grapples with the seriousness of climate change and turns more to financial incentives to reach a low-carbon ecosystem that supports the entire economy.

The Biden administration has a government-wide plan addressing how climate change could affect all sectors of the U.S. economy. The plan was part of a larger agenda to eliminate greenhouse gas emissions in half by 2030 and transition to a net-zero emissions economy.  

“There is also going to be a desire to raise revenue to deal with climate change, and for other public purposes, and carbon pricing does all those things,” Newell said. He added that while an economy-wide carbon fee would be the best solution, the administration could start by applying carbon fees to individual sectors. 

As the U.S. decarbonizes areas like the power sector and automotive sector, Newell says pressure on government regulation will intensify. “There will be an increasing recognition that to really decarbonize the economy, across all sectors, there is going to be a need for some comprehensive policies,” he said.

“There has been a significant shift across the country in terms of the seriousness with which people and legislators are confronting climate change,” Newell said. ”And that will continue to build beyond the focus on particular sectors.”  

The debate over a carbon pricing mechanism right now takes place at a time of rising concerns about inflation and prices at the gas pump that have led to discussions about whether the government should tap the Strategic Petroleum Reserve. The methane fee sparked a debate with some worrying that raising the price of methane would increase electric and heating costs for individual consumers.  

Fears of rising prices for low-income households and increasing costs for businesses will need to be considered. 

“If politicians are smart and anticipate that they need to compensate, say families that might see their bills go up as a result of a carbon price, you can drive [carbon pricing] through,” Barker said.  

In a plan put together by the Climate Leadership Council, a climate advocacy group co-founded by former Secretary of State James Baker, who served in the Bush and Reagan administrations, the idea isn’t to fund government efforts to fight climate. The Climate Leadership Council’s plan outlines that revenue collected from a carbon fee is “to be returned to American households,” said Carlton Carroll, Climate Leadership Council spokesperson.  

“Nothing would do more to accelerate innovation and invest all citizens in a clean energy future than an economy-wide carbon fee, with corresponding dividends for the American people,” Carroll said. 

The group’s carbon dividends plan cites four major benefits to consumers, including an increase in household disposable income nationwide.  

Increasing carbon pricing could be done by taxing greenhouse-gas intensive goods and services, like gasoline, or by taxing carbon emitters individually. The Climate Leadership Council is among groups advocating for pricing carbon-intensive goods as part of a U.S. climate plan, “because it will go further, faster than any other single climate policy intervention,” says Carroll, “while also driving innovation throughout the economy and making families better off financially.” 

Historically, there has been some bipartisan support for a carbon tax. The first carbon pricing proposal was introduced in 1990, and there have been several other propositions since. Though none have passed, Newell said the most recent carbon pricing proposal in Biden’s social safety and climate plan piqued the interest of Congress far more than anticipated. 

The carbon tax proposed as part of the Build Back Better plan would impose a $20 fee per metric ton of carbon.

“I would say there was a surprisingly strong interest in a carbon fee as part of the ongoing budget reconciliation process,” Newell said. 

But Mindy Lubber, CEO of sustainability investment organization Ceres, told CNBC earlier this year that while a carbon tax is one way to prevent the U.S. from being locked into a fossil fuels economy and spur the development of new energy and transportation systems, it has proven controversial in the past, and is a complicated policy tool, making it harder for all sides to reach agreement on, especially in a Senate where the votes are so tight.

A carbon tax could be closer than some people think, says Flannery Winchester, spokeswoman for the progressive Citizens Climate Lobby. ”It has gone from a hopeful idea to one that is on the verge of becoming a reality,” she said.  

The White House and 49 senators were on board with a carbon tax, but not the key vote from West Virginia Democratic Senator Joe Manchin. 

“But there is clearly a lot more consensus than there’s ever been that this policy is effective for meeting America’s climate goals,” Winchester said.

The ticket bot cometh: cities are ticketing drivers that AI says are bad [update]

The ticket bot cometh: cities are ticketing drivers that AI says are bad [update]

In a high-tech move that we can all get behind and isn’t dystopian at all, the City of Barcelona is feeding camera data from its city buses into an advanced AI, but they swear they’re not using the footage to to issue tickets to bad drivers. Yet.

UPDATE 06DEC2025: the ticket bot cometh to Chicago.

Last month, the Chicago Transit Authority (CTA) contracted with Hayden AI to equip six of its transit buses with AI-powered license plate readers intended to target illegally parked vehicles in an area bound by North Avenue, Roosevelt Road, Lake Michigan and Ashland Avenue.

As with similar pilots in Barcelona and NYC, the Hayden AI technology captures information from vehicles illegally blocking bus and bike lanes, then submits its “findings” to a human reviewer for confirmation. If the reviewer agrees with the AI, they can issue a fine of $90 for parking in a bus lane, $250 for bike lane obstruction, $50 for parking in expired meters outside of the central business district, and $140 for personal vehicles parked in commercial loading zones.

Despite those hefty fines, Chicago Mayor Brandon Johnson is quick to point out that the goal of the program isn’t to generate revenue.

“Every Chicagoan deserves a transportation system that is safe, reliable, and efficient,” said Mayor Johnson, in a statement. “By keeping bus and bike lanes clear of illegally parked vehicles, the Smart Streets pilot helps us protect our most vulnerable road users while improving the daily commute for riders across the city.”

The official release makes no mention of the fact that Hayden AI’s system generated nearly $21 million in revenue for the city in just a few months, despite the fact that thousands of those ticketed weren’t doing anything wrong.

We wrote about some of these issues back in Jun. You can read that original article, below, and let us know what you think of Chicago’s “non-revenue” claims in the comments.


Barcelona launches automated bus lane and bus stop enforcement pilot with Hayden AI

Barcelona and its Ring Roads Low Emission Zone have earned lots of fans by limiting ICE traffic in the city’s core. The city’s latest idea to promote mass transit is the deployment of an artificial intelligence system developed by Hayden AI for automatic enforcement of reserved lanes and stops to improve bus circulation – but while it seems to be working as intended, it’s raising entirely different questions.

“Bus lanes are designed to help deliver reliable, fast, and convenient public transport service. But private vehicles illegally using bus lanes make this impossible,” explains Laia Bonet, First Deputy Mayor, Area for Urban Planning, Ecological Transition, Urban Services and Housing at the Ajuntament de Barcelona. “We are excited to partner with Hayden AI to learn where these problems occur and how they are impacting our public transport service.”

Currently operating as a pilot program on the city’s H12 and D20 bus lines, the system uses cameras installed on the city’s electric buses to detect vehicles that commit static violations in the bus lanes and stops (read: stopping or parking where you shouldn’t). The Hayden AI system then analyses that data and provides statistical information on what it captures while the bus is driving along on its daily route.

Hayden AI says that, while it photographs and records video sequences and collects contextual information of the violation, its cameras do not record license plates or people and no penalties are being issued to drivers or owners of the vehicles.

So far so good, right? But it’s what happens once the six mont pilot is over that seems like it should be setting off alarm bells.

The footage is manually reviewed by a Transports Metropolitans de Barcelona (TMB) officer, who reportedly reviewed some 2,500 violations identified by AI in May alone. But, while the system isn’t being used to issue violations during the pilot program, it easily could.

And, in fact, it already has … and the AI f@#ked up royally.

AI writes thousands of bad tickets


NYC issued hundreds of thousands of tickets; via NBC.

When AI was given the ability to issue citations in New York City earlier this year, it wrote more than 290,000 tickets (that’s right: two-hundred and ninety thousand) in just three months, generating nearly $21 million in revenue for the city. The was just one problem: thousands of those drivers weren’t doing anything wrong.

What’s more, the fines generated by the AI powered cameras were supposed to be approved only after being verified by a human, but either that didn’t happen, or it did happen and the human operator in question wasn’t paying attention, or (maybe the worst possibility) the violations were mistakes or hallucinations, and the human checker couldn’t tell the difference.

In OpenAI’s tests of its newest o3 and o4-mini reasoning models, the company found the o3 model hallucinated 33% of the time during its PersonQA tests, in which the bot is asked questions about public figures. When asked short fact-based questions in the company’s SimpleQA tests, OpenAI said o3 hallucinated 51% of the time. The o4-mini model fared even worse: It hallucinated 41% of the time during the PersonQA test and 79% of the time in the SimpleQA test, though OpenAI said its worse performance was expected as it is a smaller model designed to be faster. OpenAI’s latest update to ChatGPT, GPT-4.5, hallucinates less than its o3 and o4-mini models. The company said when GPT-4.5 was released in February the model has a hallucination rate of 37.1% for its SimpleQA test.

FORBES

I don’t know about you guys, but if we had a local traffic cop that got it wrong 33% of the time (at best), I’d be surprised if they kept their job for very long. But AI? AI has a multibillion dollar hype train and armies of undereducated believers talking about singularities and building themselves blonde robots with boobs. And once the AI starts issuing tickets to the AI that’s driving your robotaxi, it can just call its buddy AI the bank to send over your money. No human necessary, at any point, and the economy keeps on humming.

But, like – I’m sure that’s fine. Embrace the future and all that … right?

Kubota, Kilter to partner on next-generation autonomous farm robot

The Japanese agriculture equipment experts Kubota are partnering with Norwegian tech startup Kilter to co-develop, pilot, and promote the new Kilter AX-1 ultra high-precision weeding robot across Europe.

The collaboration will initially target Kubota’s vegetable growing customers in Germany and the Netherlands, specifically farmers growing spinach, salad lettuces, herbs, celeriac, and strawberries who hope to benefit of higher yields and crop quality while cutting the use of chemical pesticides to an absolute minimum.

To accomplish those goals, the Kilter AX-1 uses a patented tech package it calls “Single Drop Technology.” Single Drop Technology combines AI weed recognition and ~6 mm placement accuracy to deliver micro-doses directly to weeds, protecting the crop and minimizing the impact to the surrounding soil.

Getting that 6 mm droplet application wasn’t easy. “You can’t buy a field-ready droplet applicator off the shelf,” Anders Brevik, CEO of Kilter, told AgTechNavigator. “We had to design one that survives years of dust, vibration, temperature swings, and long operating days, while keeping droplet size, timing, and placement consistent. That takes deep agronomy knowledge, a lot of engineering, and thousands of hours of field testing.”

Kilter says growers can reduce herbicide use by up to 95% by adopting the new AX-1, shifting selectivity from chemistry to smart application.

Kubota Europe’s Smart Farming Solutions Division, launched back in 2024, is working with the company’s European dealer network to train up sales staff and integrate the Kilter robot into Kubota’s broader farm solutions portfolio. There’s no word, yet, on pricing or if/when we’ll get the Kilter in North America.

Electrek’s Take

Kubota has been bringing literal tons of electrified and autonomous ag solutions to shows like CES for the past few years, and they’ve made significant waves there. With partnerships that take the sustainability push beyond decarbonization and into the realms of de-chemicalizing (that’s a word) and pro-pollenatoring (another word), they’re making real steps towards a more sustainable future for agriculture.

The future of electric farming is taking shape at John Deere [video]

The future of electric farming is taking shape at John Deere [video]

Energy independence and cost control are top of mind for farmers, and more companies are rolling out electric equipment that can be charged by solar, wind, or even on-farm biogas. With the debut of its latest next-generation electric tractor at Agritechnica last month, John Deere is signaling that it intends to lead that revolution.

John Deere says the E-Power electric tractor prototypes that it’s been quietly teasing since 2022 will be as quiet as a car, as easy to drive as a golf cart, and require minimal upkeep – and all while providing the same performance as the company’s beloved diesel tractors.

“Our goal with the E-Power tractor is to ensure it performs the same jobs as its diesel counterparts and works with the same implements, while unlocking incremental value,” explains Derek Muller, business manager for battery electric vehicle systems at John Deere. “Through our electric lineup, we’ll look to reduce operational and maintenance costs, deliver powerful and reliable performance, and intuitive operation.”

The latest electric John Deere tractor prototype, recently unveiled at Agritechnica, is equipped with a 100 hp drive motor and two, additional motors. One 130 continuous hp electric motor for the PTO, and a third for the hydraulic pump. They’ll draw power from up to five KREISEL li-ion battery packs, allowing customers significant pricing flexibility based on their ability to determine how much power and run time they need (and are willing to pay for) to get their jobs done.

The customization will go well beyond just battery size. Deere plans to offer customers a number of different tractor and equipment options, and keep costs competitive by basing them on a vehicle common architecture.

“John Deere aims to develop a single electric concept that customers can configure to their own needs,” writes Bob Karsten, at Future Farming. “Buyers will be able to choose the number of batteries (up to five, totalling 195 kWh), the axle type (narrow or wide track), and the cab (either an orchard cab or the familiar 5M cab). In essence, buyers select their preferred battery capacity. With the largest battery (195 kWh), the tractor can operate for eight hours. The target is to enable fast charging up to 80% in 30 minutes.”

Deere revealed one version of that upcoming electric tractor (above) at Agritechnica last week, but despite being an early prototype, it’s a fully functional piece that’s already seen duty with some of John Deere’s most trusted customers.

  • Daniel, an orchard customer from California, said his experience with the electric tractor led him to believe it could help ease training new operators, “I do think the tractor is much easier for drivers to understand it and to drive it. It would take less time to teach them [operators] how to use it.”
  • Tyler, a vineyard customer in California, believes that a new electric tractor could help his operation meet its sustainability goals, “When we look at our carbon footprint, greenhouse gas emissions, we want to try and reduce those as we run our equipment to farm our vineyards, we want to be conscious of the community at large.”

There’s no official word yet on when the new John Deere electric tractor platform will start reaching customers, but Big Green’s recent purchase of battery manufacturer KREISEL and its continued push into more global markets means that it can’t afford to take things slow.

You can check out a quick, virtual walkaround of John Deere’s E-Power electric tractor concept in this (admittedly older) video released around the ACT Expo, and expect more details and possible configurations at the upcoming CON/AGExpo conference in March.
