An initial assessment by the Climate Action Tracker of the impact of the Glasgow sectoral announcements for methane, coal, forests and transport show they would reduce the 2030 emissions gap between current government action and a 1.5°C pathway by just 9%, or 2.2bn tonnes of CO2e. This includes only the signatories of respective initiatives as of 10 November, 2021, and only accounts for reductions that are not already planned to achieve the submitted nationally determined contributions (NDCs).
Sectoral initiatives help implement action, but with current signatories only narrow the emissions gap to a limited extent. The Climate Action Tracker recommends that governments update their NDCs if participation in the initiative is not covered already by their target. If these initiatives gather more signatures, they could further reduce the gap by several GtCO2e.
Even with all new pledges and such sectoral initiatives for 2030, global emissions are still expected to be almost twice as high in 2030 as necessary to for a 1.5°C compatible pathway. Therefore, all governments need to reconsider their targets towards COP27 in 2022 to jointly enhance mitigation ambition.
