From retailers to banks, carmakers to councils, the bold pledges for carbon-neutral economies are being watered down or scrapped

Almost a year since Donald Trump returned to the White House with a rallying cry to the fossil fuel industry to “drill baby, drill”, a backlash against net zero appears to be gathering momentum.

More companies have retreated from, or watered down, their pledges to cut carbon emissions, instead prioritising shareholder returns over climate action.

Games such as Dragon Quest used to mobilize workers to back corporate goals including relaxing environmental rules

Toyota, the world’s biggest carmaker, is using retro-style video games to rally its US workforce behind its corporate goals, including lobbying to relax environmental rules, the Guardian can reveal.

Through an internal platform called Toyota Policy Drivers, employees can play games with names such as Star Quest, Adventure Quest and Dragon Quest, earning prizes by engaging with company messaging about policy and by contacting federal lawmakers using company-provided talking points.

Researchers noticed ‘dramatic’ changes in nutrients in crops, including drop in zinc and rise in lead

More carbon dioxide in the environment is making food more calorific but less nutritious – and also potentially more toxic, a study has found.

Sterre ter Haar, a lecturer at Leiden University in the Netherlands, and other researchers at the institution created a method to compare multiple studies on plants’ responses to increased CO₂ levels. The results, she said, were a shock: although crop yields increase, they become less nutrient-dense. While zinc levels in particular drop, lead levels increase.

Study author says tech companies are reaping benefits of artificial intelligence age but society is left to pay cost

The AI boom has caused as much carbon dioxide to be released into the atmosphere in 2025 as emitted by the whole of New York City, it has been claimed.

The global environmental impact of the rapidly spreading technology has been estimated in research published on Wednesday, which also found that AI-related water use now exceeds the entirety of global bottled-water demand.

The European Commission’s proposals to water down a 2035 ban on new petrol and diesel cars will store up major problems for the future

Two years ago, the European Union’s adoption of a 2035 ban on the sale of new petrol and diesel cars was hailed as an act of global leadership, and a declaration of faith in the journey to net zero. That the home of BMW, Renault and Fiat should decisively reverse away from the internal combustion engine was seen as a symbolic moment.

This week, Brussels proposals to water down that ban have sent a very different kind of message. Electric vehicles might be the future. But after intensive lobbying by German and Italian manufacturers, the European Commission has proposed a reprieve for new CO₂-emitting cars that would allow them to be sold after the former cut-off date. According to the EU’s industry commissioner, Stéphane Séjourné, this U-turn offers a “lifeline” to an ailing car industry that has struggled to cope with Donald Trump’s trade wars and Chinese competition.
