In October, nearly 200 countries struck a landmark deal to reduce the emissions of powerful greenhouse gases, hydrofluorocarbons (HFCs), in a move that could prevent up to 0.5°C of global warming by the end of this century. The amendment to the Montreal Protocol on Substances that Deplete the Ozone Layer, which is hosted by UN Environment, is the single biggest step the world has taken to limit global warming.
Paris Agreement comes into force
On 4 November – less than a year after it was adopted – the Paris Agreement on Climate Change came into effect after it was ratified by 55 Parties that account for 55 per cent of global greenhouse gas emissions. This fast-track ratification is a powerful confirmation of countries’ understanding of urgency of the climate change challenge. UN Environment is working with countries around the world to help them achieve the Agreement’s ambitious goal of keeping global warming well below 2°C.

Nigeria launches Ogoniland clean-up
In June, the Government of Nigeria set in motion a $1 billion clean-up and restoration of the Ogoniland region in the Niger Delta, with UN Environment guidance. The region has been subject to a succession of oil spills over the last 50 years, with devastating effects on both the environment and public health. The restoration efforts, which are based on UN Environment recommendations, could prove to be the world’s biggest-ever environmental clean-up.
