Public Climate Finance: Are We Funding Carbon Capture or Actual Emissions Reduction?
Why every dollar of public investment should be measured against independently verified life-cycle greenhouse gas reductions.
The central argument should be:
Capturing one tonne of CO₂ is not necessarily equivalent to preventing one tonne of greenhouse gas emissions.
A credible assessment must account for the entire process: energy consumption, upstream emissions, CO₂ transportation, storage performance, leakage, additional infrastructure and long-term liabilities.
Proposed article structure
- The global CCS investment trend: Why governments, development banks and major EPC contractors are investing heavily in CCS infrastructure.
- Capture versus actual emissions reduction: The difference between CO₂ captured at a plant and verified net greenhouse gas reductions across the full life cycle.
- The 25-year performance question: Who guarantees injection capacity, geological containment and environmental performance throughout a project’s commercial life?
- Public financial accountability: Should taxpayers carry long-term liabilities that private contractors and financiers cannot fully guarantee?
- A technology-neutral investment framework: Compare CCS, carbon recycling, electrification and other technologies on an equivalent basis.
- CEWT’s CRT as an alternative approach: Why smaller demonstrations of carbon circulation deserve consideration, provided their energy consumption, life-cycle emissions and economics are independently verified.
The metric that should drive our argument
Climate Effectiveness = Tonnes of CO₂e Avoided / $ Invested
Unit: tonnes of CO₂ equivalent avoided per million dollars of public funding (tCO₂e/A$ million).
The higher the value, the greater the measured emissions reduction per dollar of public investment.
We should also account for the timing and durability of emissions reductions, and distinguish genuinely avoided emissions from temporary carbon utilisation.
The article should not claim that CCS has no place in industrial decarbonisation. Instead, it should challenge the assumption that the quantity of CO₂ captured and injected is sufficient evidence of a successful climate investment.
I would close the article with this question:
If public institutions demand financial accountability for every dollar invested, should they not demand equally rigorous environmental accountability for every tonne of CO₂ claimed to have been avoided?
