Will the carbon pricing markets pass the Nietzsche Test?

1. Corporate risk teams remain split on whether carbon pricing is a technical problem or a financial risk. Technical compliance reporting drew the most votes in audience polling, 16 of 53 respondents, narrowly ahead of the 15 who called it a major financial risk comparable with liquidity or interest-rate exposure and the 12 who called it primarily a reputational risk (see Chart 2). If those who think it is primarily a legal or reputational risk are added to those who think it is a technical reporting issue, more than half the audience were not yet convinced carbon is primarily a financial risk. 2. A live show of hands at the end of the discussion found no one in the room still willing to call carbon a purely technical issue. This suggests the discussion had effected a shift from the scepticism the same audience expressed in the pre-event poll. That shift is real evidence of a discussion changing minds in the room, though a live vote of this kind should be read as a snapshot of a continuing conversation rather than a durable market signal. 3. The 2004 United Nations report, Who Cares Wins, is often cited as the origin point for treating carbon externalities as material (though others trace carbon pricing back to the 1980s). Two decades on, the International Financial Reporting Standard S2 (IFRS S2) and the European Union (EU) 's Corporate Sustainability Reporting Directive (CSRD) have given that idea a considerably harder financial edge. Even after the CSRD's scope was narrowed, its core double-materiality requirement, assessing both a company's impact on climate and climate's impact on the company, survived intact. 4. The European Central Bank (ECB) fined a French agricultural lender roughly €4 million last year for failing to adequately address climate-related risk across its loan portfolio on the expected timeline. Yet the bank had already pledged not to finance oil and gas – sectors to which it was not exposed anyway - which meant it had limited fossil-fuel exposure to manage. Its actual vulnerability, and the ECB's real concern, was the climate resilience of the farmers in its loan book. 5. Carbon accounting is far from standardised in the corporate sector. An internal review at a major oil and gas company reportedly found more than 40 different methods of carbon accounting in use across its own business, depending on which internal team was asked. Estimation errors abound. Construction projects have been found to overestimate embodied emissions by 15 to 20 per cent on average, pointing to a data-governance problem rather than a data-collection one. 6. Between 80 and 90 per cent of an oil major's emissions footprint typically sits in Scope 3 – in other words, they occur across suppliers and customers rather than in its own direct operations. Banks face an analogous concentration of carbon emissions in the loans they make to companies. This exposure to carbon risk beyond the direct control of a company creates a genuine financial dilemma for a chief financial officer asked to price a liability that cannot currently be measured to within an order of magnitude, let alone a percentage point. 7. On Scope 3 emissions, there was disagreement over what counts as a legitimate carbon strategy when a company's biggest emissions source sits structurally outside its control. One view held companies should reduce emissions directly wherever physically possible and collaborate across value chains to remove double counting before reaching for unrelated offsets. A competing view argued this is unrealistic when the largest emissions source is often a national energy supplier or a State industrial policy. No individual company can compensate for these influences by its own supply-chain management. 8. However, there are steps companies can take on Scope 3 emissions. One consumer brand moved from estimating its entire coffee supply chain's footprint to identifying which specific growing regions faced the greatest emissions risk, then directing investment toward agroforestry projects in exactly those regions rather than buying generic credits. This shift from a broad, unfocused carbon reduction strategy to carefully aimed investments was cited as a template other companies could follow. 9. A second example of practical steps companies can take on Scope 3 emissions was offered. A bank financing a hydropower plant whose revenue depended on water supplied from tropical rainforests treated buying carbon credits to protect that specific forest as an instance of project risk management rather than pure philanthropy, since the plant's ability to stay in business depended directly on an ecosystem the bank did not own. Whether this counts as insetting (a company investing in carbon reduction in its own supply chain) or offsetting was debated, though one panellist argued the label matters less than the underlying logic. 10.An audience member working in construction materials described the benefits of companies actively seeking carbon credits that directly support recycling facilities supplying their own supply chain, such as aluminium and concrete recycling plants, rather than buying generic, unrelated credits. This suggests some buyers are already moving toward carbon credits chosen for their direct relevance to a company's own physical inputs. 11. There was no consensus on what should happen to the large stock of voluntary carbon credits issued some years ago using carbon reduction methodologies since shown to be imprecise. One view held that even flawed early voluntary carbon credit purchases by companies at least represented a genuine application of the principle that whoever creates a cost should pay for it, and that retroactively shaming early buyers punishes exactly the behaviour regulators are now trying to encourage. 12. Roughly 1.8 billion tonnes of voluntary carbon credits invested in forestry have been issued under methodologies now regraded as unsound. They reflected a preference for perception rather than effectiveness, and have lumbered the carbon pricing markets with a large legacy of unretired credits that overshadows the small number of credits that have been retired. This over-supply of unwanted, low-quality credits now sits alongside scarce high-quality removal credits that command excessively high prices. This was described as a structural feature of the market, not a temporary imbalance likely to self-correct quickly. 13. One view is that the high prices are more apparent than real. A technology company, for example, has been retiring voluntary carbon removal credits at prices reported to be as high as US$500 a tonne. One theory offered was that spreading that cost across an enormous Cloud and artificial intelligence (AI) customer base makes the per-unit cost invisible, turning what looks like a premium climate commitment into a straightforwardly profitable line item rather than a pure cost. 14. The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) launched by the International Civil Aviation Organisation (ICAO) is not yet established as a model standard for carbon pricing. Physically decarbonising aviation fuel was cited at costs approaching US$1,500 a tonne, against compliance credits available at roughly US$15 a tonne. Airlines were described as still finding reasons not to pay even that lower figure, suggesting the pricing structure has not yet been made painful enough to change behaviour. 15. Data quality remains a genuine constraint on carbon pricing, panellists agreed. However, they disagreed on whether that constraint justifies waiting for better data before acting. One argued that approximate carbon data is already sufficient to direct real capital toward specific, quantifiable risks such as water security and supply-chain resilience, without waiting for a perfect set of global carbon numbers that may never arrive. 16. The panel's overall trajectory, despite starting from audience scepticism that carbon pricing had genuinely become a financial issue, ended without a single voice defending the purely technical framing embedded in the opening poll question. Whether that convergence reflects a durable shift in how companies actually manage carbon risk, or is simply the persuasive effect of a convincing discussion heard by an engaged audience, remains an open question.
