In this briefing, the Climate Action Tracker (CAT) estimates global warming by 2100 to be at an all-time low of 2.4°C. Due to recent climate action announcements at President Biden’s Leaders Summit on Climate, together with those announced since September 2020, have improved the CAT’s global warming estimate by 0.2°C. This emissions gap needs to be closed with further NDC target updates this year and targets have yet to be supported by ambitious policies.
