Total CO2 emissions from the UK's brewing industry have fallen by 42 per cent in the last decade, research has shown.
The British Beer and Pub Association (BBPA) has said there has been a reduction of 202,952 tonnes between 2008 and 2018.
The research also found that the energy used to brew a pint of beer in the UK is now 20 per cent less than it was in 2008. The water required to brew one hectolitre of beer has also reduced to an average of just 3.5 hectolitres.
Separate data from the Environment Agency acquired by the BBPA also found that UK breweries now recover and re-use 98 per cent of their waste.
The research, published in a new report by the BBPA, called 'Brewing Green: A Greener Future for British Beer & Pubs', comes as the UK's brewing and pub sectors begin setting their next sustainability targets to meet the UN's Sustainable Development Goals.
Brigid Simmonds, chief executive of the British Beer & Pub Association, said: "Britain's brewing and pub sectors are amongst the oldest and most revered around the world. To maintain this reputation, we must brew our beer and serve our pub-goers in a sustainable way.
"From reducing emissions to lowering waste, Britain's breweries and pubs are determined to be world leaders in environmental sustainability and meet the United Nation's Sustainable Development Goals."
Simon Townsend, chief executive for Ei Group, said: "As consumer focus on sustainable purchasing and responsible business increases, so does our continual pursuit of reducing energy consumption across our estate through adopting forward-thinking green initiatives. These include offering electric car charging points in pub car parks and targeted upgrades to heating and cooling equipment in pubs."
