The Entrepreneurial State Must Lead on Climate Change

Originally published at Project-Syndicate | November 4th, 2022

As a much-touted green alliance of financial institutions crumbles, the private sector has once again proven unequal to the task of climate leadership. The global transition to a net-zero economy simply will not happen at the pace that is needed unless states embrace their proper role as a market maker and investor in public goods.

CAIRO – In recent weeks, several members of the Glasgow Financial Alliance on Net Zero (GFANZ) – a group of 450 financial institutions – have quit over concerns about the cost of delivering on their climate commitments. In dropping out, they have given the lie to the notion that private financial institutions can lead the transition to a carbon-neutral economy. What the transition really needs is more ambitious states that will go beyond market-fixing to become market shapers.

The market-led approach is rooted in the belief that private financial institutions allocate capital more effectively than anyone else. The implication is that states should refrain from “picking winners” or “distorting” market competition, and confine themselves to “de-risking” green investment opportunities to make them more appealing to mainstream private investors.

But modern economic history tells a different story. In many places and on many occasions, it is public actors that have taken the lead in shaping and creating markets that then deliver benefits for both the private sector and society more broadly. Many major technological breakthroughs that we now take for granted happened only because public entities made investments that the private sector found too risky.

The real story is thus quite different from the prevailing myth. We owe many economic successes not to public actors that got out of the way, but to an “entrepreneurial state” that took the lead. Moreover, the market-led approach is at odds with the goal of delivering a just global green transition in which the costs and risks are shared fairly within and between countries. “De-risking” assumes a strategy that socializes costs and privatizes profits.

Private finance still has a crucial role to play, of course. But only the public sector can mobilize and coordinate investment on the scale required to decarbonize the global economy. The question, then, is what this approach should include.

First, states should embrace their roles as “investors of first resort,” rather than waiting to step in only as “lenders of last resort.” Around the world, public financial institutions deploy many billions of dollars each year, and, owing to their distinct design and governance structures, they can supply the kind of long-term, patient, and mission-oriented finance that the private sector is often unwilling to provide. The evidence shows that direct lending from well-governed public banks can play a powerful market-shaping role by informing perceptions of future investment opportunities.

Second, we must rethink the relationship between the public and private sector, especially when it comes to sharing risks and rewards. When public entities take risks to achieve societal goals, the private sector should not appropriate the financial rewards.

For example, if a government is funding major renewable-energy projects and other green investments, it could take an equity stake in them. Returns can also be socialized by assigning a proportion of intellectual-property (IP) rights to the state, allowing profits to be re-invested in new green projects. Importantly, firms benefiting from public finance should be subject to conditions that align their business activities with green industrial-policy objectives, fair labor practices, and other priorities.

Third, to direct private investment to green activities, and to curtail investment in harmful ones, states must strengthen and update the rules governing financial markets. Such a regime could include central banks introducing allocative green credit policies, and regulators strengthening rules and standards to prevent greenwashing and regulatory arbitrage.

Fourth, policymakers should recognize that debt finance – whether provided by the public or the private sector – is not necessarily a substitute for direct fiscal spending. The logic of repayable financial instruments is not easily reconciled with the public-good features of some climate-related investments. Investments in climate justice and reforestation will yield far-reaching returns, but not necessarily of the kind that can be used to repay a loan. Navigating these issues and delivering investment at the necessary scale will require strategic coordination across all areas of social, environmental, fiscal, monetary, and industrial policymaking.

Finally, more must be done to provide sufficient fiscal space for countries in the Global South to pursue their own domestic decarbonization and adaptation agendas. Many countries, including those that are most exposed to accelerated climate breakdown, are facing significant debt overhangs. It is now imperative that Global North debtor countries – which are responsible for most of the emissions in the atmosphere – help to reduce these burdens through debt write-offs, debt restructuring, loss-and-damage compensation, or by replacing climate loans with climate grants.

To limit catastrophic global warming, the funding for climate mitigation and adaptation must be scaled up dramatically. But the quality of the financing also matters. Rather than holding out hope that private financial institutions will translate their highly publicized trillion-dollar net-zero pledges into credible, accountable action, we should demand that states assume their proper role. That means mobilizing and directing finance toward clear and ambitious climate goals, and shaping financial markets to align with those goals. Closing the financing gap requires a radical redesign of the financial architecture and a substantive shift in financial flows. Neither will happen without policy interventions.

To specify the changes that are needed, I will moderate an all-women panel at COP27 with Barbadian Prime Minister Mia Mottley, WTO Director-General Ngozi Okonjo-Iweala, Egyptian Minister of Planning and Economic Development Hala El Said, and Scottish First Minister Nicola Sturgeon. The challenges are urgent. If states fail to take the lead on climate finance, the green transition will remain out of reach.
