The Sixth Carbon Budget report is based on an extensive programme of analysis, consultation and consideration by the Committee and its staff, building on the evidence published in 2019 on Net Zero advice. The publication also includes a report detailing the road to 'Net Zero finance' and a report by Cambridge Econometrics on the potential macroeconomic effect of the Sixth Carbon Budget and Net Zero. The macroeconomic analysis is based on a Post-Keynesian model, and suggests that UK gross domestic product will be 2-3% higher in 2050 under the pathway relative to a baseline of the continuation of existing policies.
