Claim analyzed
“Carbon capture and storage technology is an effective and scalable solution for achieving net-zero emissions.”
The Conclusion
Executive Summary
CCS technology can effectively capture CO₂ at individual facilities but is not currently a scalable solution for net-zero emissions. Current global capacity captures less than 1% of annual emissions, with prohibitive costs ($100-350/ton) requiring sustained subsidies for deployment.
Warnings
- The claim conflates technical effectiveness (90%+ capture rates) with practical scalability - current deployment captures <1% of global emissions despite decades of development
- Economic barriers are severe: CCS costs $100-350 per ton and remains uncompetitive in most applications without government subsidies
- Growth statistics can be misleading - even 54% year-on-year increases represent negligible absolute progress from a tiny baseline

The Debate
The for and against arguments
Authoritative assessments conclude CCS is both effective and scalable for net-zero pathways: the IPCC Special Report finds the mitigation potential “considerable” and able to reduce overall climate-mitigation costs (Source 1, IPCC), while WRI summarizes IEA/IPCC analysis that CCS deployment is “critical” to reach net-zero by 2050 and lays out concrete scale targets (e.g., >1000 capture facilities and ≥1 GtCO₂/yr in the U.S.), demonstrating a plausible deployment trajectory (Source 5, World Resources Institute). Real-world scaling is already underway—Global CCS Institute reports a 54% year-on-year rise in operational projects with 27 new facilities coming online (Source 6, Global CCS Institute)—and modern systems can capture ~90%+ of CO₂ from large stationary sources (Source 10, PetroSync), so cost and policy hurdles noted by some analysts do not negate the technology's demonstrated effectiveness and accelerating scalability.
Your reliance on Source 6's "54% increase" misleadingly presents relative growth from a minuscule baseline - even tripling current capacity to 140 million tons (Source 17) leaves us capturing less than 0.4% of annual global emissions, making your "accelerating scalability" claim mathematically absurd. You cherry-picked the IPCC's optimistic language while ignoring Source 2's definitive conclusion that CCS "is not economically competitive today in most of its applications" and Source 7's acknowledgment that "$100 to $250 cost range" makes CCS "heavily dependent on government support" - proving that without massive subsidies, your "demonstrated effectiveness" remains purely theoretical.
Source 2 (Belfer Center) and Source 7 (ING Think) demonstrate that CCS remains economically unviable with costs ranging from $100-$350 per ton, making it "not economically competitive today in most of its applications" and "heavily dependent on government support." Source 15 (Amigo Energy) and Source 17 (Carbon Credits) reveal the massive scalability gap, showing current global capacity of only 40-140 million tons annually against the 36 billion tons of CO2 emitted yearly - a shortfall of over 99% that exposes CCS as fundamentally inadequate for achieving net-zero emissions at the required scale.
You're committing a category error by treating “not economically competitive today without policy” as proof CCS isn't effective or scalable, when the motion is about technical/solution viability and authoritative pathway assessments explicitly judge CCS “critical” with “considerable” mitigation potential and defined scale-up targets (Source 1, IPCC; Source 5, World Resources Institute), while also noting enabling conditions can unlock deployment (Source 3, Global CCS Institute). And your “99% shortfall” framing is a static snapshot fallacy that ignores the documented acceleration in real-world buildout—operational projects rose 54% year-on-year with 27 new facilities coming online (Source 6, Global CCS Institute)—which directly undercuts your claim that CCS is fundamentally incapable of scaling.

The Adjudication
How each panelist evaluated the evidence and arguments
The most authoritative source in the pool is the IPCC Special Report on CCS (Source 1, ipcc.ch), which supports CCS as a potentially significant mitigation option, but it is very old (2005-era) and does not by itself establish present-day scalability for net-zero; among more independent, credible institutions, WRI (Source 5) summarizes IEA/IPCC pathway work as finding CCS “critical,” while Belfer/Harvard (Source 2) and ING Think (Source 7) emphasize that deployment at scale is constrained by high costs and reliance on policy support, and the Global CCS Institute items (Sources 3, 6) are industry-advocacy and thus less independent on “scalable solution” claims. Weighing independence and reliability, the best evidence indicates CCS can be effective in specific applications and is included in many net-zero pathways, but the dataset's stronger independent sources do not clearly confirm it is already an “effective and scalable solution” in general—scalability remains conditional on major cost reductions and/or sustained policy—so the claim is overstated and therefore misleading.
The claim asserts CCS is both "effective" AND "scalable" for net-zero, but the evidence reveals a critical logical gap: Sources 1, 3, 5, 9, and 10 establish technical effectiveness (90%+ capture rates) and modeling potential, while Sources 2, 7, 12, 15, and 17 demonstrate current deployment captures <1% of global emissions (40-140Mt vs. 36Gt annually) with prohibitive costs ($100-350/ton) requiring sustained subsidies—the opponent's rebuttal correctly identifies that percentage growth from a negligible base does not prove scalability has been achieved, only that it remains theoretically possible under conditions (policy support, cost reduction) not yet realized. The proponent commits a modal fallacy by conflating "can scale under enabling conditions" (Sources 3, 5) with "is scalable now," while the opponent's math (99%+ gap between current capacity and need) directly refutes the "scalable solution" component of the claim, making the overall assertion false despite CCS being technically effective at point sources.
The claim frames CCS as broadly “effective and scalable” for net-zero, but it omits that most evidence here supports CCS as a potentially important *complement* mainly for hard-to-abate sectors and often contingent on strong policy support, while current deployment remains far below gigaton-scale and costs/energy penalties are major constraints (Sources 2, 7, 12, 14, 17). With that context restored, CCS can be technically effective at capturing CO₂ in specific applications and is included in many modeled pathways (Sources 1, 5), but calling it an “effective and scalable solution” in general overstates present-day scalability and readiness, so the overall impression is misleading.
Adjudication Summary
The three panelists reached different verdicts but converged on similar concerns. The Source Auditor (5/10, Misleading) found that while authoritative sources like IPCC support CCS potential, the strongest independent sources don't confirm current scalability without major policy support and cost reductions. The Logic Examiner (3/10, False) identified critical logical gaps: the proponent conflated technical effectiveness with practical scalability, committing modal fallacies by treating future potential as current reality. The Context Analyst (5/10, Misleading) noted the claim overstates present-day readiness by omitting that CCS is viewed as a complementary tool for specific sectors, not a broadly scalable solution. All panelists highlighted the massive deployment gap (current capacity <1% of global emissions) and economic barriers ($100-350/ton costs requiring subsidies). While no consensus exists across verdicts, the Logic Examiner's identification of fundamental logical flaws in conflating potential with current scalability, combined with mathematical evidence of the 99%+ deployment shortfall, supports the False verdict despite CCS having technical merit in specific applications.
