Risk Assessment 3
(CCRA3)
The third Climate Change Risk Assessment (CCRA3) assesses a set of 61 specific risks and opportunities to the UK from climate change, grouped into 5 categories.
For the purposes of the CCRA3, risk is defined as ‘the potential for consequences where something of value is at stake and where the outcome is uncertain’
