4C researchers are participating in the presentation of the Global Carbon Budget 2022 at COP27.

The 27th edition of the United Nations Climate Change Conference of Parties (COP27) is held between 6 and 18 November 2022 in Sharm El Sheikh, Egypt.

The summit brings together politicians, scientists and civil society to discuss our changing climate and negotiate action for achieving the climate goals set by the Paris Agreement, aiming to limit global warming to well below 2°C.

COP26, last year’s summit held in November 2021 in Glasgow, ended with insufficient commitments from the parties, which would lead to a temperature rise of 1.8°C at best, if not to a much higher warming of 2.4°C. This year, world leaders are called to turn their commitments into action and negotiate impactful measures to tackle climate change. 

4C researchers are participating in the summit, bringing reliable and actionable science to policymakers in order to drive urgent action.

Launch of the Global Carbon Budget 2022

As in previous summits, the Global Carbon Project will be releasing the Global Carbon Budget for 2022 during COP27. The launch will take place on Friday 11 November 2022 at 15:45-17:15 CET at the Osiris room.

This annual study shows the amount of CO2 that human activities emitted into the atmosphere in the past year, and how this was partially balanced through uptake of carbon by the ocean and land carbon sinks. The Global Carbon Budget presents cutting-edge climate research that is of great value for policymaking, as it helps monitor the impacts of human activities on climate change and push for appropriate action.

A number of 4C scientists, including Pierre Friedlingstein, Corinne Le Quéré and Glen P. Peters, form part of the Global Carbon Project, and will participate in the presentation of the carbon budget.

The session will also highlight cutting-edge research and solutions for food and agricultural systems (more information can be found in the COP27 side event list).
