By Ben Elgin After a two-year probe, the world’s largest certifier of carbon offsets has determined that most of the credits from a massive forest-protection project in Zimbabwe, which powered green claims of Volkswagen, Gucci, Nestle and McKinsey & Co., failed to benefit the atmosphere. It’s a sharp blow to carbon markets, which have shrunk by more than two-thirds since 2021, amid ongoing concerns about the quality of carbon projects and a broader corporate pullback in climate action. “This is a big deal,” said Grayson Badgley, a research scientist at Carbon Plan, a nonprofit that analyzes climate solutions. “I haven’t seen an investigation like this before.” Conservationists inspect a community water tank in Binga, Zimbabwe.

Over the past decade, Kariba became the third-most widely used carbon project on the market, with companies relying on it to claim nearly 22 million tons of emission reductions – equivalent to half the annual climate footprint of Switzerland.

A super-polluting surprise | By Emma Court and Olivia Rudgard President Donald Trump signed a landmark law to phase down potent greenhouse gases used in air conditioning during his first term. Now, his administration wants to unwind the measure, meaning companies could keep selling the polluting ACs for longer. The Environmental Protection Agency said the proposed change is in response to a shortage of climate-friendly refrigerants needed to comply with the law, which raised prices for the products for contractors by as much as five times and left some Americans without AC at the height of summer. The agency is holding a public hearing on today before finalizing the rule change, and a spokesperson confirmed the hearing would continue despite the government shutdown. If adopted, the new EPA plan would put the US further behind other countries in phasing out chemicals that can warm the planet thousands of times more than carbon dioxide. It would also throw a wrench into a transition to new, less-polluting chemicals and equipment that’s been years in the making. In addition to eliminating a January cutoff for installations of the older ACs, the EPA aims to push back deadlines to introduce greener chemicals in commercial spaces like cold storage in stores and factories by as much as six years.

On Friday, nations voted to delay by one year the decision that would force large vessels to curb emissions or potentially incur fees of $380 per ton. The outcome was in part the culmination of a months-long campaign by US officials — including diplomats and cabinet members as well as the president himself — to fight the fee they decried as an untenable global carbon tax. The US wasn’t alone in battling the initiative; nations including Saudi Arabia, Iran and Russia had voted against the planned emissions charge in April and on Friday backed the delay. Read the behind-the-scenes account of how the US worked to postpone the landmark vote. The EU will propose stronger measures to curb emissions costs in a new and controversial carbon market to address concerns that consumers will struggle to afford to heat their homes and fill up cars. A group of firms including BlackRock’s Global Infrastructure Partners, Exxon Mobil and Banco Santander have joined forces to push for a new way to measure the carbon emissions of the products they make, buy and finance.
