- Analysis finds that between 2015 and 2023, economies
responsible for 92% of global GDP have absolutely or relatively
decoupled CO2 emissions from growth.
New analysis from the Energy & Climate Intelligence Unit
(ECIU) shows that an expanding share of the world economy is
cutting CO2 emissions while continuing to grow —
meaning decoupling is beginning to occur at scale. The study,
10 Years Post-Paris: How emissions decoupling has
progressed globally [1], uses the latest
consumption-based Global Carbon Budget data across 113 countries
representing more than 97% of global GDP and 93% of global
emissions.
Absolute decoupling happens when emissions are declining even as
the economy expands. Relative decoupling means emissions are
still increasing, but at a slower rate than economic growth.
It finds that:
- Overall, 92% of global GDP and 89% of global
emissions are in economies that have decoupled, either relatively
or absolutely, up from 77% for both in the decade before
the Paris Agreement (2006–2015).
- Between 2015 and 2023, countries representing more
than 46% of global GDP absolutely decoupled — growing
their economies while cutting CO2 emissions in absolute terms.
That share is up from just over 38% in the pre-Paris period
(2006-2015).
- The number of countries achieving absolute decoupling
rose from 32 pre-Paris to 43 post-Paris, while
those achieving relative decoupling rose from 35 to 40.
- Absolute decoupling is widespread across advanced economies,
even when adjusting for emissions embodied in imports.
Commenting on the findings, John Lang, one of the report
authors and Net Zero Tracker Lead at ECIU,
said: “We're sometimes told the world can't cut
emissions without cutting growth. The opposite is happening.
Decoupling is now the norm, not the exception — and the share of
the global economy that is decoupling emissions in an absolute
sense is steadily increasing.
“Of course, global totals matter most and CO₂ emissions
continue to rise, though at a far slower rate than 10 years ago.
Under the hood, the structural shift is unmistakable. More
countries are bending their curves, and crucially, China's CO2
emissions have been flat for 18 months and may have
peaked.”
Commenting on the findings, Gareth Redmond-King, Head of
International at ECIU, said: “The momentum
built by the Paris Agreement is unstoppable – the economic
realities make it so. Solutions like solar power have
outperformed pre-Paris predictions many times over, as costs have
plummeted and investment in clean energy outstrips that in fossil
fuels by two to one. More people are employed globally in clean
energy than fossil fuels, whilst at home the net zero industries
grow three times faster than the economy as a whole.
"Net zero remains the only solution to halting ever more
costly and dangerous impacts from climate change. That it also
offers better health, growth and jobs, and food security can only
continue to build the momentum achieved during the first decade
of the Paris Agreement.”
Momentum beyond the headlines
The report shows widespread decoupling across Europe and North
America, and in major South American and Southern African
economies. The US and the EU fall into absolute
decoupling, while India and China show relative
decoupling, with China's emissions growing far more
slowly than GDP over the 2015–2023 period.
Some of the largest proportional emissions reductions were
recorded in Western Europe, including Norway, Switzerland and the
UK. These are among a cohort of over 20 global economies which
have consistently demonstrated absolute decoupling over the past
two decades.
The report also finds that many emerging economies have made
significant turnarounds — moving from emissions rising faster
than GDP to absolute decoupling, with emissions now falling as
their economies expand. This includes Brazil, Colombia, Egypt,
Jordan and Mozambique.
Sensitivity testing
To test the robustness of these findings, the report repeats the
analysis using shifted sample windows. Across all scenarios, the
share of global emissions in absolutely decoupled economies
varies only by a few percentage points — showing clearly that the
trend is not an artefact of endpoint selection.
