Combatting the climate crisis requires society to rapidly transform all the systems that propel our economy, including power generation, buildings, industry, transport, land use and more. But by how much? And how can decision-makers make it happen? Developed by partners contributing to the Systems Change Lab, the "State of Climate Action 2021" report identifies 40 indicators across key sectors that must transform to address the climate crisis and assesses how current trends stack up against targets for 2030 and 2050 to limit warming to 1.5 degrees C. The analysis will highlight both encouraging bright spots that are witnessing exponential change as well as sectors that are well off track and demand urgent attention.
