The British government is sticking to its net-zero goal despite global conflicts affecting energy supplies. It plans to reduce greenhouse gas emissions by 87% of 1990 levels by 2042. The U.K. has a legally binding target of achieving net zero carbon emissions by 2050. Energy Secretary Ed Miliband said the government will follow the independent Climate Change Committee’s advice for the next emissions budget. Scientists said the goal aligns with the 2050 target, but details on achieving it are needed. Opposition parties argue for more oil and gas extraction to reduce energy dependence.
