That isn't in itself great news, because the bottom line to track is how much greenhouse gas we're generating.

The report is also slightly optimistic on that point: "Nonetheless, growth in power sector emissions showed signs of slowing down as rapid deployment of renewables constrained increases in fossil-fired generation. As this trend continues, we expect 2025 emissions to plateau and remain relatively unchanged."

But "plateau" isn't great news, either. That's gigatons of CO2 added per year. It would mean that we stop accelerating climate change, but we'll sail though 1.5C and 2C on our way to the IPCC's worst-case scenarios.
