Against a backdrop of a cost of living crisis caused in part by soaring energy prices, the UK’s new prime minister, Liz Truss, appointed MP Jacob Rees-Mogg as secretary of state for business and energy. In this role, Rees-Mogg will have to tackle these issues while being responsible for the UK’s legally binding target of net zero greenhouse gas emissions by 2050. It is a goal he has previously described as ‘a long way off’. Madeleine Finlay hears from environment correspondent Fiona Harvey about his plans to extract ‘every last drop’ of oil and gas from the North Sea, the possibility of fracking in the UK, and the importance of energy efficiency and renewables in addressing the cost of living, energy and climate crises together.
