The UK increased the rate at which it reduced greenhouse gas (GHG) emissions last year, but "urgent action" is needed for the country to meet its targets in 2030 and beyond, independent advisory body Climate Change Committee (CCC) said in its progress report published today.
The report assesses the UK's progress towards its net zero goals against policy set out by the previous Conservative government. The new Labour government, which has been in power since 5 July, has already set the scene for a stronger decarbonisation agenda, but it "will have to act fast to hit the country's commitments", the report says. The committee tracked progress on 28 key indicators. Of the 22 that have a benchmark or target, only five are assessed as being "on track".
The UK's GHG emissions last year stood at 393mn t/CO2 equivalent (CO2e), down on the year by 5.4pc, or 22mn t/CO2e, provisional data show. This estimate excludes contributions from international aviation and shipping, as these are not included in the UK's 2030 target of a 68pc cut in GHG emissions from a 1990 baseline. And last year's reduced emissions resulted primarily from a drop in gas demand, the CCC says. Combined gas demand in 2023 averaged 156mn m³/d, down from nearly 175mn m³/d a year earlier.
While progress has been made, the previous administration "signalled a slowing of pace and reversed or delayed key policies", the report says. The reduction in emissions last year is "roughly in line with the annual pace of change needed" to reach the 2030 target, but the average annual rate over the previous seven years is "insufficient", the committee says.
The new government has placed strong focus on decarbonising electricity in its first days in office, but this is "not enough on its own", CCC acting chief executive James Richardson said. The average annual rate of GHG reduction outside the electricity supply sector over the previous seven years was 6.3mn t/CO2e, but this will need to more than double until 2030 if the UK is to meet its targets, the CCC says.
In order to reach targets, "annual offshore wind installations must increase by at least three times, onshore wind installations will need to double and solar installations must increase by five times" by 2030. By comparison, oil and gas use should be "rapidly" reduced and the expansion of the production of fossil fuels should be limited, according to the report.
The CCC also recommended that about 10pc of UK homes will need to be heated by a heat pump by 2030, in comparison with about 1pc today. The committee criticised the exemption of 20pc of properties from the 2035 phase-out gas boiler plan, saying it is "unclear" how the exemption would reduce costs as fewer consumers would have to pay to maintain the distribution grid.
Gas-fired power generation in recent months has dropped on the back of high wind output and brisk power imports. Power-sector gas burn was 25mn m³/d in March-June, roughly half of the three-year average for the period. But if UK power demand increases with electrification, gas-fired power generation could maintain its role in the country's power mix, particularly if it is combined with carbon capture, use and storage technology, for which fast development and scale-up will need to happen this decade, the CCC says.
"Biases" towards the use of natural gas or hydrogen must be removed where electrification is the most economical decarbonisation solution in an industry sector. Power prices need to be reduced "to a level that incentivises industrial electrification".
Oil, gas industry to meet climate goals
The UK's oil and gas sector "is on track to meet its own climate goals and is not slowing down", offshore industries association OEUK said today in reaction to the CCC's report.
The UK needs a plan for reducing oil and gas demand and cutting its reliance on imports, according to OEUK chief executive David Whitehouse. "We should be prioritising our homegrown energy production," he said.
The sector reduced its emissions by 24pc in 2022 from 2018, meaning it met its target to reduce emissions by 10pc by 2025 early. The industry halved its flaring and venting and cut methane emissions by 45pc in 2022 compared with 2018, Whitehouse said.
OEUK plans to reduce emissions by a quarter by 2027 and by half by 2030 against 2018 levels. And it aims to achieve net zero by 2050.
