Repository environment

We take 12,614,400 measurements of temperature and humidity levels in our repositories each year.

Our environmental commitment

At The National Archives, we are committed to continually improving our environmental performance – to reducing our energy use and carbon emissions, preventing pollution and reducing our waste streams. On 14 May 2010, the Prime Minister set a target for central government to reduce its carbon emissions by 10% within 12 months. On 6 July 2011, the Cabinet Office and DECC announced that government has achieved this target, saving a total of 13.8%.

In 2016-17, carbon emissions from energy use in our buildings reduced by 8% compared with 2015-16 (a 58% reduction compared with the 2009-10 baseline). Operational (‘business as usual’) waste reduced by 4% compared with 2015-16 (a 40.4% reduction compared with the 2010-11 baseline).  Also in 2016-17, 40.4% of our total waste was re-used or recycled.
