The window for avoiding more than 1.5°C of global warming has almost closed, the Intergovernmental Panel on Climate Change has warned, and will shut unless the world takes drastic action now.
Coal use must drop 95 per cent by 2050 on 2019 levels, oil by 60 per cent and gas 45 per cent to meet the 1.5°C goal, figures that Jan Christoph Minx, one of the authors of the report, says are “very striking”. Even meeting theweaker target of 2°C would leave a “a substantial amount of fossil fuels unburned” and render up to $4 trillion of fossil fuel infrastructure “stranded”. “We need to end the age of fossil fuels,” said Minx, speaking at a press briefing.
“Rapid and deep” emissions reductions will be needed across all sectors, using a mix of renewable energy, carbon capture and storage , lower energy demand, better energy efficiency and a huge ramp-up of ways to remove COfrom the atmosphere, such as direct air capture machines, says the report. Deployment of CCS was found to be “far below” the amount modelled needed to reach climate goals.
For the first time, the IPCC considered the role of behavioural change on emissions reductions, such as shifting diets. It found that such measures could cut emissions by up to 70 per cent by 2050 in some sectors. “The way we move around, the way we eat, the way we generate energy, everything needs to change,” says Pete Smith, an IPCC author.
Despite claims in some quarters that cutting emissions will be too expensive, the IPCC said mitigation costs for meeting the 2°C target would be “small” compared with global GDP growth, putting it 1.3 to 2.7 per cent lower in 2050 than in a business-as-usual world. Today’s document is the third of four reports by the IPCC that make up its “sixth assessment report”: the first was on the
