Environment: COP meetings keep happening; emissions keep rising

COP 27 in Sharm El-Sheikh, Egypt. United nations climate change conference. 7-18 November 2022 will be international climate summit. Flat vector modern banner.

Four reports and Greta Thunberg highlight the failure of 30 years of COP meetings to slow climate change. Our weekly environment report.

Use of fossil fuels and non-fossil fuels in 2050

The IEA report I summarised above includes the following figure (page 58). It shows the amount of energy (in Exajoules) provided by fossil and non-fossil energy sources from 2020-2050. The figure on the left shows the likely trajectories if all governments’ current policies are pursued. The figure on the right shows the trajectories that are needed to reach net zero emissions by 2050. Current policies will more than double non-fossil supplies by 2050, whereas the net zero course needs an almost four-fold increase. The big change though is in the supply of fossil energy. Current policies will produce only a marginal reduction in fossil fuel energy, but to achieve net zero emissions fossil energy must be reduced to approximately one-fifth of 2020 levels by 2050.
