The chairs of the Business, Energy, and Industrial Strategy (BEIS) Committee and the Environmental Audit Committee (EAC) have urged the chancellor to use the forthcoming Covid-19 recovery package to boost low carbon industries, warning that infrastructure and investment decisions made in the coming months will be "critical" to building the UK's resilience to the escalating climate crisis.

In a letter sent to Chancellor Rishi Sunak today, committee chairs Darren Jones and Philip Dunne argued that a net zero aligned economy recovery could establish the UK as a climate leader ahead of its presidency of the G7 and COP26 climate conference in 2021, while stimulating the economy, generating jobs, and improving public health and wellbeing.

International post-crisis stimulus spending is likely to dwarf existing spending on climate change and strategies that deliver new carbon-intensive energy, transport, and industrial infrastructure projects would prove a "historic mistake", they warned.

"The UK's post-crisis economic recovery package presents a major opportunity to accelerate investment on climate adaptation and cutting emissions to net zero," Jones and Dunne wrote. "This is necessary to avert an even greater future national and global crisis caused by climate change. Crucially, it will also spur innovation, create jobs and bring substantial economic benefits to the UK and the wider world."

Pressure is mounting on the government to implement a so-called green recovery to the coronavirus crisis, after months of calls from civil society, academia, business, and politicians for Ministers to prioritise investments in low-carbon infrastructure and nature restoration projects that can accelerate the UK's transition to a net zero economy.

Just last week, the Committee for Climate Change (CCC) called on the government to support a raft of labour-intensive net zero projects in a hard-hitting report that warned the UK was not making sufficient progress towards its 2050 net zero target.

In the document, the government's climate advisors warned the UK was far from being on track to achieve net zero, highlighting insufficient progress in improving building energy efficiency, decarbonising transport and industry, and changing land use, as well as a "dearth of climate adaption planning in government".

It remains to be seen whether the government will heed the avalanche of calls it has received over recent months and beef up its net zero decarbonisation efforts through its forthcoming economic recovery package, which is expected in early July.

Responding to the demands in today's letter, a spokesperson from the Treasury said that the government would work to deliver clean and sustainable economic growth as it took steps to reboot the economy.

"Throughout this crisis, we've continued to take our environmental responsibilities seriously and remain committed to meeting our climate change and wider environmental targets, including our commitment to net zero by 2050," the spokesperson said. "We are committed to investing in stimulating a green recovery, including recently announcing a £250m emergency active travel fund for the rapid expansion of cycle and walking routes across England. As we take action to rebuild our economy we will aim to drive clean, sustainable and inclusive growth across all regions of the UK."

Reports have suggested that Ministers are looking to create thousands of green jobs in carbon capture and storage (CCUS), hydrogen, active transport, electric vehicle charging infrastructure, and building efficiency programmes. However, the government has failed to attach any specific climate-related conditions to the various loans and bailout packages already provided to automakers and aviation companies, causing significant concern among campaigners. There are also fears in some quarters that the bulk of any green stimulus measures could be deferred until the autumn budget.

In today's missive, the committee chairs point out that the British public is likely to back a green recovery, flagging findings ­- also published last week - that revealed that 79 per cent of Climate Assembly UK 'strongly agree' or 'agree' that economic recovery plans should be designed to achieve net zero emissions.

Climate Assembly UK was convened last year by a cross-party group of six House of Commons Select Committees - including the EAC and BEIS Committee - in order to get a take from an informed cross-section of the British public on how the country should meet its net zero goals.

The letter to the Chancellor comes as the EAC launches a new inquiry, dubbed 'Greening the post-Covid recovery' and ahead of the BEIS Committee's evidence hearing on Thursday, which will examine the Committee on Climate Change's progress report and the results of the UK Climate Assembly.

The EAC's inquiry will monitor the government's economic recovery packages and identify opportunities that can improve environmental safeguarding. It expects to publish a report ahead of the Autumn Budget, when the government is expected to reveal its full spending package.
