The US EPA finalized strict new tailpipe emissions standards for heavy-duty vehicles like semi-trucks and buses for 2027-2032 model years. The standards aim to avoid 1 billion tons of greenhouse gas emissions and provide $13bn in annualized net benefits. Heavy-duty vehicles account for 25% of transportation sector emissions, contributing around 30% of US greenhouse gas emissions. The new standards are technology-neutral and performance-based, allowing manufacturers to choose the best emissions control technologies for their vehicles and customers.
