UK climate change risk assessment 2022

This report fulfils the requirement of the Climate Change Act 2008 for the government to lay before Parliament a five-yearly assessment of the risks for the UK of current and predicted impacts of climate change. This third UK Climate Change Risk Assessment (CCRA3) report to Parliament outlines the UK government and devolved administrations’ position on the key climate change risks and opportunities that the UK faces today. This is based on the Independent Assessment of UK Climate Risk, the statutory advice provided by the Climate Change Committee (CCC), commissioned by the UK government and devolved administrations

This report identifies sixty-one climate risks cutting across multiple sectors of our society. It identifies a wide range of potential costly impacts of climate change including on health and productivity, affecting many of households, businesses and public services. Impacts range from a deterioration in soil health and agricultural productivity to impacts on water availability and thereby the country's alternative energy supply. The Valuation Report for the CCRA3 estimates that, for eight of the risks identified by the CCC, economic damages by 2050 under 2°C could exceed £1 billion per annum. This CCRA3 also highlights the international nature of many climate risks which can cause cascading effects across borders and sectors with significant impacts on the UK.
