Around 30 years ago, many developed countries started a process of absolute decoupling of their emissions of CO₂ and energy use from economic growth. This means keeping emissions stable, or better yet, shrinking them, while still growing the economy.
As a result, GDP is now much higher than it was in 1990 in the UK, France, Germany and the US, but CO2 emissions are lower. This is not just because of the deindustrialisation of the west: emissions decrease even if we include our imports from countries like China.
