  The Global Methane Pledge and other methane measures may potentially
undermine CO2 mitigation in certain countries, unless they are considered as
additional to the existing Nationally Determined Contributions to strengthen
overall greenhouse gas emission targets. Maintaining the progress on CO2
mitigation in the revision of Nationally Determined Contributions after the
first Global Stocktake, while pursuing the immediate benefits from methane
mitigation, is necessary to address climate change in the long-term.
