Implode-o-Meter News - Major automakers strike climate deal with California, rebuffing Trump on proposed mileage freeze

``The deal comes as the Trump administration is working to finalize a huge regulatory rollback that would freeze mileage requirements for cars and light trucks next fall at about 37 miles per gallon on average, rather than raising them over time to about 51 mpg for 2025 models -- the level the industry and government agreed to during the Obama administration. The proposal would also revoke California's long-standing authority to set its own rules under the Clean Air Act, a practice the federal government has backed for decades.
...
Officials from the National Highway Traffic Safety Administration, which is co-writing federal tailpipe standards, noted in a statement that the administration's proposal does not prevent manufacturers from building more-efficient vehicles if they so choose.

Under the new accord, the four companies, which represent about 30 percent of the U.S. auto market, have agreed to produce fleets averaging nearly 50 mpg by model year 2026.
...
The share of the U.S. auto market affected by the new terms could grow significantly if other automakers join the deal. Last month, the Canadian government also pledged to align mileage requirements for its auto market with California rather than the Trump administration.
...
As part of the new agreement, California has pledged to certify vehicles from the four automakers and provide the companies additional flexibility in how they meet each year's emissions goal: They will improve their fleet's average efficiency by 3.7 percent a year, as opposed to 4.7 percent dictated under the Obama-era rules.
