Global Climate Action  

At the twenty-first session of the Conference of the Parties (COP 21) in Paris, it was agreed that mobilizing stronger and more ambitious climate action by all Parties and non-Party stakeholders is urgently required if the goals of the Paris Agreement are to be achieved.

In decision 1/CP.21, the commitments from all actors are recognized, including those launched through the Lima–Paris Action Agenda, as well as the urgent need to scale up the global response to climate change and support greater ambition from governments.

At COP 22 in Marrakech, a High-Level Event on Accelerating Climate Action was held to highlight outcomes from the Action Events throughout the conference and culminated with the launching of the Marrakech Partnership for Global Climate Action; a new framework to catalyse and support climate action.

Collaborative Climate Action Across the Air Transport World

Improve air transport fuel efficiency and stabilize the sector's net CO2 emissions from 2020

List of participants will be added in due course

Lead Organisations



The initiative supports short-, medium- and long-term goals to cut emissions from aviation. Apart from introducing a global market-based mechanism, it supports developing new, more efficient aircraft technology and sustainable alternative fuels while promoting and deploying operational improvements to reduce CO2 emissions from aircraft already in service. It calls for better use of infrastructure, especially in air traffic management.


2016 Activities
Outreach and Capacity building:
ATAG and IATA have organized a series of educational roundtables in seven cities worldwide. ICAO has also run a series of five Global Aviation Dialogues on market-based measures to address climate change in Africa, Middle East, Europe and North Atlantic, Asia-Pacific and the Americas, followed by the ATAG Sustainable Aviation Forum and the ICAO High-level Meeting in May 2016 where the proposal on a global market-based mechanism was refined, for further discussion and decision by the 39th ICAO
Assembly in September 2016.
Knowledge Building:
ICAO has worked with governments, industry and civil society to deliver the world’s first CO2 Standard for Aeroplanes in February 2016. This is the very first ‘global design Standard’ for CO2 emissions for any sector, and it was realized after six years of intensive work by many of the best experts in the world. The Standard guarantees up to a 10% fuel efficiency gain for each new type developed from 2020, relative to the average of current production aircraft types. It also addresses new deliveries of those aircraft that are already in-production from 2023. If they have not complied with the standard by 2028, they cannot be produced anymore. For context, approximately 40% of current production aeroplane type designs will need to be improved to meet the Standard.

Quantitative Impact


Deliver the world’s first CO2 efficiency Standard for aircraft in February 2016. New standard will come into effect from 2020 and will apply to all new aircraft. Current aircraft will be phased in to the standard.
