The UK has pledged to reach net-zero by 2050. But has a pandemic, the fallout from the war in Ukraine and now an economic crisis derailed our plans to decarbonise? Or have they provided an inflexion point, accelerating necessary change? With the energy crisis has come a renewed emphasis on security of supply. Does that bind us more firmly to fossil fuels - or spur the transition to cleaner fuels and new technology? And has a cost of living crisis been a catalyst for change in consumer and corporate behaviour - or made going green seem unaffordable and less of a priority? Dharshini David speaks to policymakers, business leaders and experts and asks whether the economy, or political will, is the main driver in reaching net zero.
