Net zero by 2050 will hit a major timing problem technology can’t solve. We need to talk about cutting consumption

"Many climate activists, scientists, engineers and politicians are trying to
reassure us the climate crisis can be solved rapidly without any changes to
lifestyle, society or the economy.

To make the vast scale of change palatable, advocates suggest all we have to do
is switch fossil fuels for renewable power, electric vehicles and energy
efficiency technologies, add seaweed to livestock feed to cut methane and
embrace green hydrogen for heavy industries such as steel-making.

There’s just one problem: time. We’re on a very tight timeline to halve
emissions within eight years and hit net zero by 2050. While renewables are
making major inroads, the world’s overall primary energy use keeps rising. That
means renewables are chasing a retreating target.

My new research shows if the world’s energy consumption grows at the pre-COVID
rate, technological change alone will not be enough to halve global CO₂
emissions by 2030. We will have to cut energy consumption 50-75% by 2050 while
accelerating the renewable build. And that means lifestyle change driven by
social policies."
