Iata is optimistic for an agreement on a Carbon Offset and Reduction Scheme for International Aviation (CORSIA) when governments meet for the 39th Assembly of the International Civil Aviation Organisation later this month.

The draft negotiating text for CORSIA, published last week, broadly aligns with the aviation industry’s call for a mandatory global carbon offset scheme as a tool to help manage the industry’s emissions as it pursues its goal of carbon-neutral growth.

But instead of being mandatory from the start, the draft text defines a voluntary “pilot and implementation” period between 2021-2027 after which participation would be mandatory for all eligible states.

Iata director general and chief executive, Alexandre de Juniac, said: “I am optimistic that we are on the brink of a historic agreement – a first for an industry sector at the global level.

“The aviation industry would have preferred a more ambitious timeline than is currently outlined in the draft text.

“However, what is most important is that the substance of the negotiating text will allow for meaningful management of aviation’s carbon footprint. Airlines support it and urge governments to agree when they meet at ICAO.”

Iata is encouraging governments to commit to their voluntary participation as soon as possible.

“Last year’s much lauded Paris climate change agreement was a combination of voluntary measures to which the vast majority of countries have already committed themselves. We expect no less of an outcome from the ICAO Assembly,” de Juniac said.

“The industry is ready. There is really no reason for governments not to volunteer. Indeed, the US, China, Canada, Indonesia, Mexico, the Marshall Islands, and 44 European countries have already indicated their willingness to participate.

“Now is the time for other states to match their political leadership, by coming to the Assembly already committed to participate, even if the scheme is voluntary at the initial stage.

“Airlines are committed to environmental responsibility. But achieving it requires a partnership with governments. That is clear in the development of a global market-based measure such as CORSIA.

“And it is the same for day-to-day operations. Airlines are investing heavily in new technology, the development of sustainable alternative fuels and operational efficiency.

“Our message to the states attending the ICAO Assembly is that they must match our efforts.

“This is particularly the case with investments to modernise air navigation infrastructure which will bring cost-efficiency benefits along with improved environmental performance.

“Similarly, government incentives to commercialise sustainable alternative fuels are critical to unlocking their environmental benefits with increased production capacity and lower costs,” said de Juniac.
