“It’s not easy being green”, the signature song of Kermit the Frog, might well serve as the motto for the climate change strategy for the Ministry of Defence and the UK armed forces – said to be the most ambitious of any military in the world.

n the run-up to the COP-26 conference that the UK co-hosts with Italy in Glasgow this November, the Defence Ministry has unveiled its policy paper under the somewhat unglamorous title: “Climate Change and Sustainability Approach.” Despite the mangled grammar, it outlines an astonishingly radical path for the forces and the ministry. It fully aims to meet the 2050 zero carbon emission target – for the forces themselves and all their establishments, real estate and backup facilities.
