US aerospace firms commit to net zero emissions by 2050 -sources

US aerospace manufacturers are poised to strengthen a climate target by pledging to reach net-zero emissions by 2050, echoing a commitment to be discussed by global airlines on Monday, according to industry sources and a document seen by Reuters. The US Aerospace Industries Association will commit on Monday to work with airlines and governments to achieve the target, joining a growing aviation industry consensus that also includes airports, according to the sources. Global airlines are expected to vote on a similar proposal at the annual meeting of the IATA in Boston on Monday. A broader aviation industry lobby, the Air Transport Action Group, is also expected to sign up later this week. The target replaces a previous goal of halving net emissions by 2050 from 2005 levels, which was intended to mirror the Paris climate agreement to limit global temperature increases this century to 2 degrees Celsius above pre-industrial levels. <br/>
