Global carbon capture deployment will fall 0.53 gigatonnes short of the International Energy Agency's 2030 benchmark of 1.67 Gt, even under optimized policy, technology and cost pathways, according to a benchmarking study published April 8, 2026 in npj Environmental and Social Sciences.

The paper, led by Lin Yang and Xian Zhang at Inner Mongolia University, modeled counterfactual scenarios across 21 countries operating CCUS projects. Findings show integrated improvements lift projected 2030 capture capacity to 1 Gt, double the 0.5 Gt baseline trajectory, yet still leave a 0.53 Gt deficit against the IEA target tied to net-zero pathways.

"Current improvements unlock only one-third of the potential capacity, insufficient to meet 2030 goals," the authors wrote, "threatening the achievement of 2040 and 2050 climate targets."

Where does the operating capacity sit today?

Operational capture capacity reached 0.172 Gt CO2 in 2024, a 138.89% rise versus 2013. The U.S. and Canada together control more than 75% of global operational scale. A further 773 projects sit in the pipeline, with North America holding 55.76%, Europe 27.94%, and Asia plus the Middle East just 11.77%.

Why is the global distribution so unbalanced?

The authors identify a Matthew Effect across the sector. Global Gini coefficients for capture capacity have run between 0.70 and 0.84 since 2020 and now trend upward. Technology concentration runs even starker, hitting 0.8 by 2024 as CCUS patents concentrate in a handful of jurisdictions.

Counterfactual cost reductions deliver just 1.60% capacity gains in high-capacity countries but 11.80% in low-capacity systems, a 7:1 ratio the authors flag as evidence that scale has not yet translated into economies of scale globally.

What drives deployment more than cost?

Policy variables contribute 44.80% of national capture capacity, technology 37.82%, and cost 17.38% — an approximate 6:5:2 weighting. A policy-intensity threshold of 12.00 was identified through piecewise regression; policy levers only shift deployment meaningfully above that mark.

The U.S. profile runs 47.66% policy, 34.55% technology, 17.80% cost, anchored by the Inflation Reduction Act's 45Q tax credits. Norway registers 53.46% technology contribution, the highest globally, anchored by standardized storage at Sleipner. China's policy share is 39.52% (ranked 18th), reflecting state-led demonstration under the dual-carbon strategy rather than formalized fiscal subsidies.

The authors described policy as shifting from "powerful catalyst" to "placebo" once demonstration gives way to commercial scale, with technology breakthroughs carrying the next phase.

How are national models clustering?

PCA-K-means clustering grouped the 21 countries into three deployment typologies:

• Policy-led, single-axis: U.K. with nine planned CCUS clusters.
• Coordinated dual-driven: U.S. (market-based) and China (state-led).
• Constrained: subdivided into high-cost policy and technology laggards (UAE, Belgium, Norway, Germany), policy-cost coordinated systems (Canada, Japan), and EOR-dependent operators (Brazil, Australia, Qatar, Kuwait).

From 2021 to 2024, Moran's I indices for policy, technology and cost ran negative and statistically significant, signaling geographic dispersion rather than clustering — the herd effect breaking down as leaders and laggards diverge.

What would close the gap?

Capture costs declined 17.79% globally from 2013 to 2024 on incremental scale. The U.S. Department of Energy's commercial viability benchmark of $30 per ton remains unmet. Capture itself consumes 60% to 80% of total CCUS project outlays, and policymakers in Beijing have already begun favoring carbon-market mechanisms over CCUS deployment in 2022–2024.

The next regulatory milestone sits with the Green Climate Fund-backed Council for Geoscience–Sasol CCUS feasibility work in South Africa and pending Indonesian and Kazakhstani carbon market rules — both due before the 2030 reporting cycle that will show whether the next 4 Gt of growth materializes, or whether the IEA's 1.67 Gt target recedes further out of reach.
