The eight most popular net-zero policy measures chosen by members of the British public could result in a 42% reduction in greenhouse gas emissions by 2030 if taken together immediately, reveals a report by think tank Demos and not-for-profit the WWF. This reduction is greater than the UK government’s existing target of a 39% reduction by 2030, compared with 2019 levels.

Demos and the WWF recently released the Climate Calculator, which allowed 20,000 members of the public to weigh in on individual emissions-reduction policies, to create a combination of measures to cut emissions by 39% by 2030.

The report proposed specific measures across eight categories. The most popular policy focused on heat pumps and received support from 97% of respondents. This policy would see the government-led installation of heat pumps in 1.4 million existing homes each year by 2030, with 770,000 of those homes also getting fresh insulation.

Other popular measures included a tax for businesses of £75 per tonne of CO2 equivalent and a progressive tax on frequent fliers, starting at 10% for a second flight, 20% for a third flight and so on. For drivers, the motorway speed limit would be reduced to 60 miles per hour.
