US tightens greenhouse gas emission standards for heavy trucks

The Environmental Protection Agency (EPA) has announced the most stringent US standards yet for greenhouse gas emissions from heavy-duty vehicles such as large rigs and buses.

Here's What We Know

The rules apply to heavy-duty vehicles in the 2027-2032 model year and are aimed at reducing emissions, which are one of the main sources of climate change pollution.

The new standards are expected to avoid one billion tonnes of emissions by 2055, which is equivalent to reducing the pollution from 13 million tanks of petrol.

Large vehicles play a significant role in greenhouse gas emissions. The new EPA standards are also designed to improve air quality for the 72 million Americans who live close to trucking routes.

It is estimated that fuel and maintenance cost savings will range from US$3,700 to US$10,500 per year for a heavy-duty truck purchased in 2032 as a result of these new standards.

Such moves to implement new vehicle emissions standards are part of the US strategy to meet the climate goals set by the Biden administration and the Paris Climate Agreement.
