10 Years Post-Paris: How emissions decoupling has progressed

Using Global Carbon Budget data across 113 countries (>97% of global GDP, 93% of emissions), the study finds decoupling of CO2 from GDP has accelerated since the Paris Agreement: absolute decoupling rose from 32 countries in the pre‑Paris decade to 43 in 2015–2023, with an additional 40 showing relative decoupling (vs 35 pre‑Paris); economies accounting for 46.3% of global GDP and 36.1% of emissions now show absolute decoupling and 92% of GDP/89% of emissions sit in economies that have decoupled in some form. The shift reflects many 'Improver' countries—including advanced economies and large emitters in Latin America, Africa and the Middle East—moving to absolute decoupling, while a small number have backslid due to rapid industrialization or weak growth; results are robust to time‑window changes despite COVID‑related volatility. For investors, the findings indicate structural progress that lowers the emission intensity of large parts of the global economy and creates a clearer basis for scaling decarbonization strategies, but global emissions continue to rise and achieving net zero still requires sustained, economy‑wide declines.

Analysis

Using Global Carbon Budget data covering 113 countries (over 97% of global GDP and 93% of emissions), the study documents an acceleration in decoupling since the Paris Agreement: absolute decoupling increased from 32 countries pre‑Paris to 43 in 2015–2023, and relative decoupling rose from 35 to 40 countries. Economies accounting for 46.3% of global GDP and 36.1% of emissions now show absolute decoupling, while 92% of global GDP and 89% of emissions sit in economies that have decoupled in either relative or absolute terms.

A sizeable cohort of “Improvers” — including advanced economies and major emitters across Latin America, Africa and the Middle East — moved from expansive recoupling to absolute decoupling, while a small set of countries slipped backward due to rapid industrialization or stagnating growth. The authors note robustness to time‑window shifts, though year‑to‑year volatility (notably COVID) can temporarily alter classifications.

For markets, the findings imply a structural reduction in emission intensity across large swathes of the global economy, creating a clearer basis for scaling decarbonization strategies; however global CO2 is still rising and achieving net zero requires sustained, economy‑wide declines. Sentiment around the finding is mildly positive (sentiment score 0.32) with modest market impact (0.25), suggesting selective opportunities rather than a broad market re‑rating.

Key Decisions for Investors

• Increase exposure to sectors and companies that directly benefit from decarbonization (renewables, grid and storage, efficiency technologies, green finance) in markets showing absolute decoupling, given these economies now represent nearly half of global GDP, Monitor emissions intensity and economic-growth trajectories in rapidly industrializing markets that have backslid and consider underweighting or hedging exposures where emissions are rising faster than GDP, Use updates to the Global Carbon Budget and decoupling indices as explicit rebalancing triggers and watch for transitory COVID‑style volatility that can create short‑term recoupling noise, Prefer active and engagement‑oriented strategies and targeted allocations to green bonds and sustainable infrastructure where policy momentum and measurable decoupling increase the likelihood of durable cash flows and risk mitigation
