The UK must deliver against its renewable energy targets and support a global shift away from fossil fuels, the independent advisory Climate Change Committee (CCC) said today in a report mapping out the next steps for the country after the UN Cop 28 climate summit.
There is "an obligation on the UK to support the acceleration of the global transition away from fossil fuels", the CCC wrote. It recognises that UK fossil fuel production is declining, but said as a "developed country with a binding commitment to transition to net zero", London should reassess whether new oil and gas exploration is in line with the principle of common but differentiated responsibility (CBDR), it said. CBDR is a key tenet of the Paris climate agreement. It refers to the duty of all countries to take climate action, but acknowledges that the types of action they take will depend on their national circumstances.
The UK has introduced legislation to provide a yearly North Sea oil and gas licensing round. Almost 200 countries agreed to transition away from fossil fuels in December at Cop 28.
Countries also agreed at Cop 28 to triple renewable energy capacity to 11TW by 2030 and to double energy efficiency by the same date. The Cop 28 agreements "require a sharper domestic response [from the UK] and time is now short for the gap to be bridged", the committee wrote. UK targets for offshore wind and solar are "broadly consistent" with the Cop 28 pledge, but an increase in onshore wind is required.
The committee warned of planning and permitting barriers. On energy efficiency, it said the UK has delivered "efficiency improvements… at an average rate of 3.5pc a year since 1990". The UK is unlikely to double its energy efficiency, as it is "relatively advanced in its decarbonisation journey", the CCC found.
The committee noted wide global recognition for "the effectiveness of the UK's underpinning climate governance framework and its strength in climate diplomacy", but warned of a "perception of slowing UK climate ambition among Cop 28 delegates". This was owed to the new oil and gas licensing legislation, the government's approval of a new coal mine in December 2022 and prime minister Rishi Sunak backtracking on some net zero policies in September, the CCC wrote.
The committee flagged "subsequent positive policy announcements", such as the zero emissions vehicle mandate and a carbon border adjustment mechanism by 2027. The government should "ensure it accompanies strong domestic climate policy with communications outputs that acknowledge this progress", the committee found.
