To assess the economic impact of coastal erosion, Defra complies with the methodology used by government which is set out in the green book and is in line with the most advanced knowledge in the field. We are committed to maintain this high standard as new data becomes available and we are building evidence about climate change and sea level rise. Our methodology for appraising coastal erosion projects, for grant in aid, already includes benefits that come from extending the life of properties or any other asset at risk of being lost to the sea because of coastal erosion.
The Government is investing £5.2 billion over six years in flood and coastal erosion schemes to better protect communities across England. Around 1in 6 of the projects in the £5.2bn 2021-27 programme aim to better protect coastal communities.
