The fight against climate change is one of the biggest challenges facing the world today. Climate change impacts the whole world, but in different ways. The world's poorest people have the lowest emissions, but feel the impacts of climate change hardest. To avoid the worst impacts of climate change, we must reduce the world’s emissions of greenhouse gases.
We can limit global warming to 1.5°C if we succeed in halving the world’s emissions by 2030, and then halving them again by 2040. Everyone must take part in this, in particular people living in rich countries with high consumption and emissions.
