Fuel efficiency rule for US heavy duty trucks
The first national fuel efficiency and greenhouse gas emissions standards for medium and heavy-duty trucks and buses in the United States were announced on 9 August, covering vehicles made between 2014 and 2018. Heavy-duty vehicles account for 17 per cent of transportation oil use and 12 per cent of all US oil consumption. Nearly six per cent of all US greenhouse gas emissions and 20 per cent of greenhouse gas emissions from the transportation sector in 2007 were produced by heavy-duty vehicles. The businesses that operate and own these commercial vehicles are expected to save some US$50 billion in fuel costs and more than 500 million barrels of oil over the life of the programme. Greenhouse gas emissions are expected to be cut by 270 million metric tons.
