Energy Secretary Greg Clark has laid out fresh energy efficiency targets for the public sector.

Clark aims to cut greenhouse gas emissions by 43% by 2019 to 2020 compared to 2009 to 2010 levels.

He thinks the reductions could save the public purse £340 million.

The previous target was to reduce emissions by 32% by 2019 to 2020, compared with 2009 to 2010 levels, which has been exceeded.

NHS saves £2bn

Clark said: “Our new, ambitious target for reducing emission across our central estate shows how this government is continuing to lead the world and rise to the challenge of tackling climate change.

“We have made significant progress so far, meeting our previous target three years early and saving just over £100m last financial year as a result.

“The potential savings from this can make a big difference across the wider public sector, with the NHS saving £2 billion over the last decade; money that can be put straight back into frontline services where it’s needed most.”
