Britain’s small and medium-sized businesses are being placed at the centre of the most consequential climate decision since the Climate Change Act, after the government tabled a Seventh Carbon Budget that would cap UK emissions at 535 million tonnes of CO2 equivalent between 2038 and 2042, an 87 per cent reduction on 1990 levels.
Announced on Tuesday by the Department for Energy Security and Net Zero, the proposed limit mirrors to the megatonne the advice handed down by the independent Climate Change Committee, and lands as Britain absorbs its second fossil fuel price shock in five years, this time triggered by the war in Iran rather than Russia’s invasion of Ukraine.
For SME owners watching their energy bills lurch upwards once more, the political framing is unusually direct. Energy Secretary Ed Miliband cast the budget as a defensive measure for “family and business finances”, arguing that homegrown clean power is the only credible route off what he called the “rollercoaster” of global hydrocarbon markets. Half of all UK recessions since 1970 have been triggered by fossil fuel shocks, according to Treasury-cited analysis published alongside the announcement.
The economic prize, on the numbers tabled by ministers, is substantial. An independent report from the Energy and Climate Intelligence Unit, with analysis from CBI Economics, calculates that the UK’s net zero economy now generates £105 billion in gross value added and underpins more than one million jobs, and crucially for Business Matters readers, more than 96 per cent of the 23,000 firms operating in the sector are small or medium-sized enterprises.
Those businesses are, on the data, materially more productive than the wider economy. Net zero employers generate £119,300 of economic value per full-time job, around 48 per cent above the UK average, and pay workers an average of £43,142 — comfortably above the national median. Wages across the sector run 11 per cent higher than the UK average, according to the Aldersgate Group.
