A series of agreements between groups of countries have been announced so far:
- In a surprise announcement, the US and China agreed to work together this decade to limit global temperature rise to 1.5C
- More than 100 world leaders promised to end and reverse deforestation by 2030, including Brazil, home to the Amazon rainforest
- The US and the EU announced a global partnership to cut emissions of the greenhouse gas methane by 2030 – reducing methane in the atmosphere is seen as one of the best ways to quickly reduce global warming
- More than 40 countries committed to move away from coal – but the world’s biggest users like China and the US did not sign up
- A new alliance that commits countries to setting a date to ending oil and gas use – and halting granting new licences for exploration – was launched
