Clear communication and accessible data are key to informed discussions about climate change. To this end, we introduce the UK Co-Benefits Atlas, an interactive online visualisation atlas presenting and explaining data on the potential socio-economic impacts of achieving climate action targets in the UK. The data includes 11 co-benefits and co-costs of climate actions for over 46,000 data zones, connected with 17 socio-economic attributes. Analyses and visualisations aim to make these data accessible, understandable, and useful for businesses, investors, researchers, third sector organisations and policymakers across Scotland and the wider UK.
