Current programmes will not deliver net zero, says Climate Change Committee

The UK government’s current programmes will fail to deliver net zero, according to a hard-hitting report from the independent Climate Change Committee (CCC).

In its first comprehensive appraisal of UK’s net zero strategy, the CCC finds major failures in delivery programmes towards the achievement of the UK’s climate goals and warns that the current strategy will not deliver net zero. 

At a time when the urgency of moving away from fossil fuels, securing energy supplies and cutting carbon emissions has never been clearer, the CCC report says that credible government plans only exist for over a third of the UK’s required emissions reductions to meet the Sixth Carbon Budget in the mid-2030s; with a fair wind we will manage another quarter; and over a third cannot be relied on to deliver the necessary emissions reductions.

In a landmark 600-page assessment, the CCC has revamped its framework for monitoring the UK’s climate progress, focusing on the changes needed on the ground to achieve net zero. Across the economy, the CCC has developed detailed new progress indicators to assess the risks of net zero delivery.

Last year, the CCC applauded the government for setting ambitious targets and launching a new net zero strategy. 

Policies are now in place for most sectors of the economy, but the CCC’s thorough review of progress finds scant evidence of delivery against these headline goals so far. There are some bright spots of progress, but in most areas the likelihood of under-delivery is high. 

This, says the CCC, is a high-wire approach to net zero. For the UK’s climate lead to be effective, the world must have confidence that we will keep our promises and that we have a clear and effective programme to achieve our commitments.

Lord Deben, CCC chairman, said: “The UK is a champion in setting new climate goals, now we must be world-beaters in delivering them. In the midst of a cost-of-living crisis, the country is crying out to end its dependence on expensive fossil fuels. I welcome the government’s restated commitment to net zero, but holes must be plugged in its strategy urgently. The window to deliver real progress is short. We are eagle-eyed for the promised action.”

The CCC says that UK emissions are now almost half (47%) their 1990 levels. Emissions rose 4% in 2021 as the economy began to recover from Covid-19 but were still 10% below 2019 levels. Further progress must be led by government policies with clear direction, credible delivery mechanisms and suitable incentives to shape private sector action. In no sector of the economy is this yet complete. Today’s report makes over 300 recommendations for filling out policies over the next year, reflecting the scale of the task at hand as the government moves from strategy to implementation.

The areas of strongest progress are backed and led by well-designed Government policy:

• Deployment of renewable electricity. Emissions from electricity generation have fallen by nearly 70% in the last decade. With offshore wind, business has shown that given the right market conditions and support it can cut costs dramatically and deploy low-carbon solutions rapidly.
• Electric cars are being adopted in greater numbers each year. Their rise is already ahead of CCC and Government growth projections, showing that consumers and households are willing to adopt low-carbon options when offered a cost-effective, good quality product.

In other areas, low-carbon options remain in their infancy. Policy has not yet begun to guide the promised private sector action:

• Energy efficiency in homes. Given soaring energy bills, there is a shocking gap in policy for better insulated homes. Government promised significant public spending in 2019 and committed to new policies last year, neither has yet occurred. The UK continues to have some of the leakiest homes in Europe and installations of insulation remain at rock bottom.
• Agriculture and land use have the weakest policies in the CCC’s assessment, despite being vital to delivering net zero and the government’s other goals on food security and biodiversity. Progress in reducing farming emissions has been glacial. The government’s food strategy of a fortnight ago did little to address these issues. They must be tackled in the new land use framework promised for next year.

The CCC now warns that:

• The current strategy will not deliver net zero. Credible government plans exist for over a third of the UK’s required emissions reductions to meet the Sixth Carbon Budget in the mid-2030s; with a fair wind we will manage another quarter; and over a third cannot be relied on to deliver the necessary emissions reductions.
• Delivery must be actively managed. In any case, our plans must be based on realistic assessment. While some policies may be more successful than expected, not all policies will deliver. These risks cannot credibly be tackled with an even greater reliance on greenhouse gas removal technologies. The Government should develop contingency plans, such as encouraging reduced consumer demand for high-carbon activities (e.g., through healthier diets, or curbs to growth in demand for flights).
• There has been slow progress on the cross-cutting enablers of progress. The net zero strategy contains warm words on the wider enablers of the transition, but little progress. There is no public engagement strategy three years after the net zero target was signed into law; HM Treasury has yet to set out how the full range of costs and benefits of the transition will be shared – it must urgently review its tax strategy to support the net zero transition; comprehensive reform of planning legislation to reflect the UK’s international and national commitments to net zero is required; and we still await the urgently needed Future Homes Strategy. Bottlenecks, such as skills gaps and planning consents for infrastructure, should be anticipated and tackled early.
• Local delivery. The CCC welcomes the new local net zero Forum, but it remains unclear how central, devolved and local government will operate in concert to deliver net zero.

The CCC says the rest of the world must also get to grips with the delivery of net zero. UK success is doubly important as an example of what can be achieved, as a template for others to draw on. Effective delivery of net zero will be needed across the world if the Glasgow Climate Pact is to have the legacy that the UK aimed for at COP26 last year.
