(Reuters) – U.S. aerospace manufacturers have pledged to reduce their carbon emissions and help meet a climate goal. The commitment is similar to that made by international airlines, as reported by industry sources. Reuters also saw the document.

According to sources, the U.S. Aerospace Industries Association (USAIA) will make Monday a commitment to join a growing consensus in the aviation industry that includes both airports and airlines to reach the goal.

AIA could not be reached immediately for comment.

The International Air Transport Association (IATA) annual meeting will be held in Boston Monday.

The Air Transport Action Group is another lobby in the aviation industry that will likely sign up this week.

The new target replaces the previous goal of halving net emission by 2050 compared to 2005 levels. This was to reflect the Paris climate agreement that aims to limit global temperatures rises to 2 degrees Celsius more than preindustrial levels.

This year, a U.N. study found that there is now a 40% chance for global temperatures to temporarily exceed 1.5 degrees Celsius pre-industrial levels over the next five decades.

According to environmental groups, the net zero 2050 goal is not sufficient and should be enforced through government action. Around 3% of all global emissions comes from aviation.

“Aviation won’t get to net zero by 2050 unless it accepts binding climate laws set at national level,” said Andrew Murphy, aviation director at Brussels-based Transport & Environment.

It includes major commercial aviation companies such as Boeing (NYSE) Co, Honeywell International and Spirit AeroSystems.

Airbus, a European aircraft manufacturer, has stated that it will support the 2050 goal.

Boeing sent questions to ATAG, AIA about the goal.

According to sources, manufacturers pledged to increase their investment in new technology to make more efficient aircrafts. This includes hybrid engines that will be available for service within the next decade.

Aerospace manufacturers, airlines and airport operators are requesting government support to increase the production of sustainable aviation fuel (SAF), in order to meet their targets.
