The Green Economy Myth: Why Net-Zero Pledges Are Not the Same as Policy

We hear it constantly: the green economy is being driven by corporate net-zero pledges and voluntary sustainability commitments. That is wrong. As practitioners, we know the real engine is legally binding policy. The gap between pledges and law is stark. According to the OECD Climate Action Monitor 2025, 110 to 114 countries plus the EU have adopted net-zero targets covering about 88% of global emissions, but only 30 countries and the EU—just 17.7% of emissions—have enshrined them in law. That is the difference between a press release and a binding cap. So let's answer the questions we actually get from clients, investors, and policymakers.

Does the Paris Agreement actually force countries to cut emissions?

No. The Paris Agreement is a legally binding treaty—it entered into force on 4 November 2016, and 195 Parties have joined—but its core commitments are voluntary. Each country submits a Nationally Determined Contribution (NDC) every five years, and there is no enforcement mechanism. The first global stocktake at COP28 in 2023 called on governments to speed up the transition away from fossil fuels, but it did not compel anyone. So when someone says "Paris will solve it," we push back: Paris is a framework for coordination, not a compliance regime.

Are corporate net-zero pledges driving real emissions cuts?

Not yet at the scale needed. The numbers speak: current NDCs commit to only a 14% collective reduction by 2030 versus 2022 levels, far short of the 43% the IPCC says is needed to limit warming to 1.5°C (OECD Climate Action Monitor 2025). Meanwhile, global greenhouse gas emissions reached a record 57.7 gigatonnes of CO2 equivalent in 2024, up 2.3% from 2023. Voluntary pledges are not bending the curve. What bends the curve is policy that changes relative prices—carbon pricing, mandates, and standards.

What policy tools actually work?

We have three proven levers: carbon pricing, regulation, and targeted phase-outs. Carbon pricing is the most efficient. The World Bank's State and Trends of Carbon Pricing 2024 reports that carbon pricing revenues hit a record $104 billion in 2023, with 75 instruments in operation, covering 24% of global emissions—up from just 7% when the first report was released. That is real money and real coverage. But pricing alone is not enough; it must be paired with regulation to force technology adoption. The Montreal Protocol is the gold standard: signed in 1987, it phased out ozone-depleting substances, and its Kigali Amendment of 2016 added a phase-down of hydrofluorocarbons, powerful greenhouse gases. UNEP says the ozone layer is well on its way to recovery. That is what binding, universal policy looks like.

Which sectors should we target first?

Methane. It is the fastest lever we have. The U.S. State Department notes that methane accounts for half of the average 1.0°C of warming the world suffered over the past decade and that reducing methane is the fastest strategy available to reduce warming. The Global Methane Pledge, launched at COP26, commits to reducing overall methane emissions by 30% below 2020 levels by 2030, with over 100 countries representing 70% of the global economy and nearly half of global methane emissions signed on. We tell clients: if you want a quick win, cut methane. It buys time for the harder CO2 transition.

Is carbon pricing enough to drive the green economy?

No. Carbon pricing is necessary but insufficient. The IEA's Net Zero Roadmap 2023 concludes that tripling global renewable power capacity by 2030 is the single largest driver of emissions reductions to 2030. Pricing can help, but you also need direct investment and mandates. The IEA calls for doubling the rate of energy efficiency improvements, increasing annual energy intensity improvement to just over 4% per year to 2030, and cutting energy sector methane emissions by 75%. And it puts a price tag on it: global clean energy spending must rise from about $1.8 trillion in 2023 to $4.5 trillion annually by the early 2030s. That is not happening through voluntary pledges alone.

What about adaptation and biodiversity?

They are part of the green economy, but they are underfunded. The Kunming-Montreal Global Biodiversity Framework, adopted in December 2022, sets 23 targets for 2030, including conserving at least 30% of terrestrial and marine areas and restoring 30% of degraded ecosystems. But these targets are not binding in the same way as the Montreal Protocol. We argue that biodiversity and climate policy must be integrated; you cannot solve one without the other. Yet the funding gap remains. COP29 in Baku focused on climate finance, with trillions said to be required. That is the missing piece.

Bottom line

The single best move for anyone serious about the green economy is to stop treating voluntary pledges as policy and start demanding binding, enforceable rules—carbon pricing, methane regulations, and renewable mandates. That is what actually shifts capital and cuts emissions. Net-zero pledges are a start, but they are not the finish line. Law is.
