New research highlights the importance of engaging policymakers in net-zero scenario approaches, finding that their close involvement could lead to scenarios with energy demand reductions of up to 45% in the case of the UK.

Policymaker-led scenarios and public dialogue facilitate energy demand analysis for net-zero futures - Nature Energy
New research finds that policymakers coleading energy scenario design has the potential both to better align scenarios with policymakers’ priorities and to question current policy, by substantially reducing energy use at half of the cost of technology-focused approaches.

The government’s data release (based on provisional figures) is here: www.gov.uk/government/s... The progress made in cutting UK emissions by cleaning up our energy supply should be celebrated - it shows what’s possible. The progress made on reducing transport emissions (so far), is less inspiring
Figure 8: Greenhouse gas emissions from domestic transport, UK,
1990-2024 (MtCO2e)

Description of findings:

Domestic transport sector emissions fell by 2% between 2023 and 2024, largely due to reductions in road vehicle diesel use, and despite a rise in emissions from road vehicle petrol use. Domestic transport sector emissions continue to remain below levels seen prior to the
COVID-19 pandemic. In 2024, domestic transport sector emissions are estimated be 12% lower than in 2019, the last pre-pandemic year.

Between 1990 and 2024, domestic transport sector emissions have reduced by 15%. Primarily as a result of a continual growth in vehicle kilometres travelled on road, domestic transport emissions grew to a peak in 2007, 8% higher than in 1990. Since then, emissions from this sector had fallen to around 1990 levels up until 2019, driven mainly by improvements in new
car fuel efficiency, as well lower traffic growth than in previous years as a result of a dip following the 2008/2009 recession.
