California regulators on Friday voted to ban the sale of new diesel big rigs by 2036 and require all trucks to be zero-emissions by 2042, a decision that puts the state at the forefront of mitigating national tailpipe pollution. Heavy-duty trucks represent nearly one third of the state's nitrogen oxide and more than one quarter of its fine particle pollution from diesel fuel, according to the California Air Resources Board While medium and heavy-duty trucks are just 10% of the vehicles on the country's roads, they emit 25% of the greenhouse gas emissions from transportation, according to the Union of Concerned Scientists, a nonprofit.
