The majority of our greenhouse gas emissions come from the energy we use across our facilities. The Group’s greenhouse gas emissions decreased by 2% in 2018 largely due to reductions in energy usage at some of our larger sites.  Improvements to energy management across the estate support this downward trend, but factors such as milder weather and changes to operating profiles can contribute significantly depending on the site in question.
