UK ratifies new agreement to tackle global warming

The UK has become one of the first nations to complete ratification of a landmark agreement to reduce emissions from appliances that play a major role in global warming

The UK has today become one of the first nations to ratify a landmark agreement that will play a major role in preventing global warming by reducing emissions from appliances such as air conditioning units and refrigerators.

The Kigali amendment to the UN Montreal Protocol commits nations to reducing hydrofluorocarbon greenhouse gases (HFCs) by 85% between 2019 and 2036.

These harmful greenhouse gases could have risen by up to 11% by 2050 and the United Kingdom is one of the first countries to approve the landmark UN agreement to help prevent that from happening.

The Montreal Protocol is already one of the most successful treaties ever agreed, having phased out 98% of ozone depleting substances – including chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons. As a result, the ozone layer is showing the first signs of recovery.

The Kigali amendment to the Montreal Protocol, which the UK has completed ratifying, goes even further and extends targets to HFCs. Although HFCs do not harm the ozone layer, they have a global warming potential thousands of times greater than carbon dioxide.

Consequently this deal is likely to avoid close to 0.5 degrees Celsius of global warming by the end of this century, making it the most significant step yet in achieving the Paris climate agreement goal of keeping temperatures well below two degrees.

Environment Secretary Michael Gove said:

"Adopting this ambitious target marks the UK as a world leader in tackling climate change. This deal will reduce global greenhouse gas emissions by the equivalent of around 70 billion tonnes of carbon dioxide by 2050 - the same as more than 600 coal fired power stations would produce during that time.

"The UK, along with the rest of the EU, has already begun to phase down HFCs by 79% between 2015 and 2030.

"The Montreal Protocol will result in an additional UK reduction equivalent to around 44 million tonnes of carbon dioxide."
