The 13th edition of the annual report provides an overview of the difference between where greenhouse emissions are predicted to be in 2030 and where they should be to avert the worst impacts of climate change.
Under this year's theme "The Closing Window - Climate crisis calls for rapid transformation of societies", the report finds that policies currently in place point to a 2.8°C temperature rise by the end of the century. Implementation of the current pledges will only reduce this to a 2.4-2.6°C temperature rise by the end of the century, for conditional and unconditional pledges respectively.
The report considers transformations required in the sectors of electricity supply, industry, transport and buildings. It also investigates cross-cutting systemic transformations of food systems and the financial system, illustrating that there is immense potential to reduce emissions beyond current mitigation pledges.
