This is the second report this month to call for a ban on flaring in the next two years. A cross-party report by the House of Commons environmental audit committee made the same recommendation on 5 January.
Mr Skidmore was commissioned by the former prime minister, Liz Truss, to review UK proposals to reach net zero emissions by 2050.
Last year, the government accepted a ruling by the High Court that its net zero strategy was unlawful. The landmark judgement agreed with arguments by Friends of the Earth, ClientEarth and Good Law Project that the strategy failed to show how the UK’s legally-binding carbon budgets would be met.
The review ran to 340 pages and had 129 recommendations.
It said flaring was responsible for 22% of carbon emissions on oil and gas fields. About 70% of oil and gas field emissions were from powering equipment on platforms, it said.
The offshore industry published a Methane Action Plan in 2021 to reduce emissions and flaring. This committed the industry to a 50% methane emission reduction by 2030, compared with 2018 levels. Shell has committed to zero routine flaring by 2025.
