The United States has joined the global drive to achieve 100% zero-emission truck and bus sales by 2040, agreeing to sign a nonbinding memorandum of understanding at the 2022 UN Climate Change Conference (COP27) in Egypt.

By signing MOU, the US establishes a clear path for heavy- and medium-duty vehicles to generate zero emissions.

“We have to work together across oceans and borders to meet our clean energy goals,” said US Energy Secretary Jennifer Granholm.

The MOU is a global commitment that paves the way for 100% zero-emission new truck and bus sales, with a benchmark of 30% of them coming by 2030.

“By committing to this goal alongside many other nations, the United States is affirming that we are serious about meeting our responsibility on climate and protecting our children’s future,” said US Senator Martin Heinrich.

The transportation sector is the leading emitter of Greenhouse Gas Emissions in the US, at 27%, and most developed nations globally.
