The UN is hoping more ambitious 2035 targets will build momentum. As of September 2025, 36 countries have submitted new or updated targets for 2030 or 2035, covering around 23% of global emissions. The European Union has flagged an indicative 2035 target of 66.3-72.5% below 1990 levels. If countries instead continue to emit at levels in line with their 2030 targets, warming will be well over 2C. These estimates may change as leaders announce more 2035 targets.
