Aircraft makers, airlines, airports and air traffic controllers pledged on Tuesday to work towards "carbon-neutral growth" and reduce their industry's contribution to global warming. The declaration committed commercial players including Embraer, Bombardier, Boeing and Airbus to support cleaner fuels, improve fuel efficiency, better manage air routes, and work "to achieve greenhouse gas reductions wherever they are cost-effective." "We are committed to a pathway to carbon-neutral growth and aspire to a carbon-free future," the signatories said.
