This graph shows the top 5 sources of emissions abatement from changes by companies, technology adoption by individuals and behaviour changes by individuals. By some distance, the two largest sources of emissions reductions will be from decarbonising our electricity supply and switching from petrol and diesel cars and vans to electric vehicles. The third largest will be from the adoption of low-carbon heating systems in residential buildings.
The total emissions abatement required by 2050 is 591 MtCO2e/year. These three changes will account for 44% of the UK’s future decarbonisation alone. The last two of these changes rely on changes by individuals, showing the importance of individuals to delivering net zero.
