Fossil fuel companies are able to challenge California’s ability to set stricter standards reducing the amount of polluting coming from cars, the US supreme court has ruled in a case that is set to unravel one of the key tools used to curb planet-heating emissions in recent years.
The conservative-dominated supreme court voted by seven to two to back a challenge by oil and gas companies, along with 17 Republican-led states, to a waiver that California has received periodically from the federal government since 1967 that allows it to set tougher standards than national rules limiting pollution from cars. The state has separately stipulated that only zero-emission cars will be able to sold there by 2035.
