The UK has become one of the first countries to ratify a landmark agreement to limit the emissions of a super greenhouse gas.
The Kigali amendment to the UN Montreal Protocol, agreed by more than 150 nations in October last year, commits them to reducing hydrofluorocarbons (HFCs) by 85% between 2019 and 2036.
The harmful greenhouse gas, commonly found in fridges and air conditioning units and which has a global warming potential thousands of times greater than carbon dioxide, could have risen by up to 11% by 2050.
The UK, along with the rest of the EU, has already committed to phasing 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.
“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.”
