For a while, carbon was the villain – an invisible exhaust fume to be taxed, capped or buried. Now, carbon has been rebranded as a commodity.
Suddenly, everyone – from investment bankers to Amazonian villagers – is talking about carbon credits, offsets and futures markets. The logic is seductive: put a price on pollution, trade permits and let the market find the cheapest way to decarbonise.
However, after two decades of experiments, from Kyoto to Glasgow, one uncomfortable truth remains: a truly efficient and equitable carbon market is not merely a technical problem. It is a political and moral minefield.
So, how should the world approach the carbon agenda so that the outcome benefits the environment, society and governments alike? Experts believe the answer lies not in a single global market, but in a layered, hybrid ecosystem that prioritises integrity, justice and pragmatism over financial speculation.
We must first stop pretending carbon is like wheat or gold. Commodities markets work because a barrel of oil is identical whether pumped in Texas or Saudi Arabia. But a tonne of carbon avoided in Berlin is not the same as a tonne stored in a mangrove in Indonesia.
Permanence, additionality and leakage are not abstract accounting terms – they are the difference between genuine climate action and corporate greenwashing. Too many credits today fund projects that would have happened anyway or that could literally go up in smoke during the next wildfire season.
The world should therefore move towards jurisdictional and sectoral carbon credits, verified by an independent, science-based global body akin to the Intergovernmental Panel on Climate Change (IPCC) for carbon markets. No more bespoke, unverifiable rulebooks.
Second, separate compliance and voluntary markets, but link them intelligently. Governments need compliance markets with hard caps. The European Union Emissions Trading System, California’s system and China’s nascent national market are imperfect but essential. These should cover heavy industry, power generation and aviation, with auctioned allowances rather than free giveaways to fund a just transition.
Meanwhile, voluntary markets should be reserved for companies going beyond regulatory requirements, not replacing them. However, both markets should share a common transparent registry. A credit used for compliance cannot also be counted towards a corporate net-zero claim. The world needs a central, publicly auditable ledger – call it a Carbon Trust Protocol – to eliminate double-counting and fraud.
Third, put a floor under the carbon price and a ceiling on offset use. Without a minimum carbon price (say, US$50-US$75/tCO2e, rising over time), markets will oscillate between being too cheap to matter and too volatile to support long-term planning. A global price floor agreed by G20 nations, with rebates for lower-income countries, would drive meaningful investment in clean technologies.
At the same time, no company should be allowed to offset more than 20 per cent of its compliance obligation. The remainder must come from actual emissions reductions. Otherwise, carbon markets become indulgences for the wealthy – environmental absolution without sacrifice.
Fourth, ensure carbon revenues flow back to communities, not merely government coffers. The biggest failing of existing markets is equity. When a forest is protected for carbon credits, who benefits? Too often, it is intermediaries and speculators, while Indigenous guardians lose access to their traditional lands.
The solution lies in benefit-sharing agreements enshrined in law. At least 50 per cent of revenues from nature-based carbon credits should go directly to local stewards. Likewise, proceeds from auctioned allowances should fund green skills training, pensions for coal workers and renewable energy access in underserved communities. Otherwise, the carbon agenda will deepen the very inequalities it claims to address.
Fifth, governments must be honest about the limits of markets. Carbon credits are not a substitute for regulation, investment or behavioural change. The world has tried to market its way out of the climate crisis, yet emissions continue to rise. A tonne of carbon not emitted has value only if the underlying sources of emissions are also being eliminated.
Alongside any carbon market, governments must mandate sectoral decarbonisation pathways, phase out fossil fuel subsidies and invest heavily in public transport, grid storage and regenerative agriculture. Carbon markets are a tool, not a strategy.
Ultimately, the carbon agenda will benefit everyone only if we stop treating carbon as a financial derivative and start treating it as a public utility. That means less Wall Street and more agroecology. Less blockchain for offsets and more blockchains of trust. Less abstract “net zero” rhetoric and more verified, local and equitable emissions reductions.
Carbon has taken centre stage. Let us not waste the spotlight on another round of speculative theatre. Let us build markets that are rigorous, redistributive and real – because the climate will not forgive another decade of hot air.
There is no denying that an effective carbon market faces many challenges. This calls for a serious rethink of the outcomes we seek in implementing the carbon agenda.
