Trade groups representing United, Boeing and other industry leaders are pushing nations to support the United Nations proposal, which would require companies to offset their emissions growth by funding environmental initiatives.
The aviation industry is supporting a United Nations proposal to limit pollution from international flights even though the measure may eventually cost companies $24 billion annually.
Trade groups representing United Continental Holdings, Boeing and other industry leaders are pushing nations to join the agreement, which would require companies to offset their emissions growth by funding environmental initiatives. The accord, being brokered in Montreal during 11 days of talks beginning Tuesday, would be the first global-climate pact targeting a single industry.
The outcome is far from certain. The deal has backing from at least 60 nations, including the U.S. and most of Europe. Yet in recent days China, which had previously expressed support for the accord, issued a joint proposal along with Russia and India pushing to change key elements of the proposal.
Exhaust from international flights accounts for about 2 percent of global-greenhouse gases, yet was largely omitted from the Paris accord on climate change last year because delegates feared divvying up responsibility for global routes could derail the broader deal.

With aviation emissions forecast to triple by 2050, airlines believe that regional or global regulation is inevitable. If their pollution must be controlled, airlines would prefer a single international standard, saying it would be far cheaper and easier than following a patchwork of local programs.
“We recognize that as an industry, we have an impact on climate change,” said Michael Gill, executive director of the Air Transport Action Group, which represents airlines, engine makers, airports and pilots. “The industry is willing to pay its share. We just want to pay our share in the most economic way possible.”
To be clear, the 15-year agreement would not force airlines to cut their pollution. Instead, companies would compensate for any emissions growth after the accord begins in 2020 by buying credits that back renewable-energy development, forest preservation or other environmental endeavors. Airlines estimate the annual industrywide cost may be as much as $23.9 billion by 2035, or 1.8 percent of projected revenue.
If the U.N.-sponsored deal fails, companies run the risk of facing even costlier regulation if Europe or others push ahead with regional plans.
Environmentalists also are pushing for the deal in Montreal, saying it’s an important first step that can be improved over time. Yet they criticize the current proposal for relying on voluntary participation during the first six years. And they say the low cost of environmental offsets could let companies off easy
“It’s peanuts,” said Bill Hemmings, of the Brussels-based environmental group Transport & Environment. “It gets them off the hook. Without enforced safeguards, it’s a massive green-washing exercise.”
Nonetheless, supporters of the accord say it’s a critical piece of the effort to stave off erratic floods, droughts and other dire impacts of global warming. In addition to the U.S. and Europe, the agreement has garnered pledges of support from the United Arab Emirates, South Korea, Singapore and dozens of others nations responsible for most aviation emissions.
On the eve of the talks, however, China proposed broad changes to the accord through a joint statement with India and Russia, pushing to make airlines in the U.S. and other wealthy nations responsible for offsetting the majority of emissions. The three nations argued that the current proposal would unfairly punish growing airlines in developing nations and drive them into bankruptcy.
Officials plan to finalize the agreement during the talks that begin this week, hosted by the U.N.’s International Civil Aviation Organization. More than 2,000 delegates are expected to attend, making it the organization’s largest assembly ever.
Environmentalists say the accord hinges on whether it can draw enough nations to participate during the initial voluntary phase to cover 80 to 90 percent of emissions. Several countries with fast-growing aviation sectors — including Brazil and India — have indicated they would wait until the deal becomes mandatory in 2027.
Officials continue to debate how to balance responsibility between large airlines that emit most emissions and small, growing carriers from developing nations. The current proposal calls for Delta Air Lines, Deutsche Lufthansa and other industry leaders to initially subsidize the growth of smaller carriers.
Over time, all airlines would be responsible for offsetting their own emissions growth. The U.S. has pushed for that transition to happen as soon as possible. Brazil and other developing nations have argued for it to happen slowly.
