Policymakers and academics envision energy demand reductions beyond typical policies in the United Kingdom - Nature Energy
Co-design of energy transition pathways with policymakers and the public lead to more significant demand-side reductions than current supply-side-focused policy. When policymakers work directly with academics to re-consider how and why we use energy in our everyday lives, politically feasible, significantly cheaper options with 45% less energy demand are possible.

New Nature Energy paper!🎉Co-created scenarios with UK policymakers & public show demand-side action can cut energy use by 18–45% by 2050 at half the cost of tech-only paths and slash carbon removal needs by 70%. People-centred approaches can reshape net-zero planning👇 www.edrc.ac.uk/publications...

📢 The UK must act on the Climate Change Committee’s advice. Christian Calvillo, @jrbarrett.bsky.social, @martiskainen.bsky.social and Hannah Corbett highlight 3 priorities: ✅ Clear leadership & public engagement ✅ Stronger energy demand monitoring ✅ A fair transition for all tinyurl.com/daushfdb

Good illustration of the alternative options available to the government when considering how to approach decarbonisation of surface transport. Shows car-kms travelled per capita in latest CCC advice against ‘positive low energy futures’ (ie scenarios that are demand-led)

The Climate Change Committee published its recommendations for the UK’s “seventh carbon budget”, covering 2038 to 2042. Professor John Barrett reviews the budget and finds that not only is net zero possible, but also that it has a wide range of benefits. theconversation.com/will-the-uks...

As the UK government digests the findings, we suggest greater consideration of the “social” transformation that examines how we travel and what we buy, to fully unlock the benefits of net zero.

John Barrett @jrbarrett.bsky.social · 26/02/2025
The report gives less consideration to demand making the technological transition harder and more expensive than necessary, and increases the risk of failure. More energy must be generated, more car miles need to be driven, and more materials and products must be supplied.

John Barrett @jrbarrett.bsky.social · 26/02/2025
It relies heavily on electrification implementing known and established technologies at speed. These include heat pumps for homes and industry, electric vehicles and renewables. It reduces reliance on currently expensive and emerging technologies. A positive move.

John Barrett @jrbarrett.bsky.social · 26/02/2025
Key findings - the transition to net zero is not only possible but highly beneficial. It will strengthen the economy, deliver warmer homes, cheaper household bills, reduced air pollution, greater energy security with less reliance on imported gas, and many other benefits.

6.3m properties now at risk from flooding in England. 43% higher than the Environment Agency's last report in just 2018. Climate change is hitting harder than expected. UK emissions reduction targets—set up to 14 years ago—aren't fit for purpose. We need to pass the Climate & Nature Bill #CANBill

Report says rivers, the sea and surface water endangering properties and that number could hit 8m by 2050

Maybe to early to say, but is there a sense of the possible leakage rate of the CO2? In other words, what percentage of CO2 is likely to be "mitigated"?

It is definitely less than what is needed for a per capita equitable distribution of the remaining carbon budget. As a starting point, I would like the UK Government to provide the details for how the 2030 and 2035 NDC will be delivered. At the moment, no credible pathway has been provided.

Along side rapid decarbonisation, energy demand falls by 38% from today. It's not possible to reach the target without transforming how we use energy. It has to combine both efficiency and sufficiency measures.
