Abstract

This paper estimates multipliers for spending in clean energy and biodiversity conservation to help inform stimulus measures for a post-COVID-19 sustainable recovery. Using a new international dataset, part of which was especially assembled for this analysis, we find that every dollar spent on key carbon-neutral or carbon-sink activities—from zero-emission power plants to the protection of wildlife and ecosystems—can generate more than a dollar’s worth of economic activity. The estimated multipliers associated with green spending are about 2 to 7 times larger than those associated with non-eco-friendly expenditure, depending on sectors, technologies and horizons. These findings survive several robustness checks and suggest that ‘building back better’ could be a win-win for economies and the planet.

We thank Michel Berthélemy (OECD-Nuclear Energy Agency) for providing nuclear energy investment data. We are deeply indebted to Greg Kaser, Philippe Costes and King Lee (all World Nuclear Association), as well as to Victoria Alexeeva Bertrand Magné, Henri Paillere and Aliki Van Heek (all International Atomic Energy Agency) for the illuminating discussions on nuclear energy data and the sector more generally. We are indebted to Joshua Goldstein and Steffan Qvist who helped us contact them. We also thank Michael Waldron and Pablo Gonzalez at the International Energy Agency for providing us with data on supply and power generation of both clean and fossil fuel energy. In addition, we are grateful to Tim Searchinger and Chris Malins for providing broken down data from their 2020 World bank paper on agricultural subsidies and explaining methodologies to us. Dan Miller kindly agreed that we used the global dataset that he originally produced on conservation spending and was later used for publications in Nature and PNAS. Conversations with Frank Hawkins, Thomas Lovejoy, Juha Siikamaki, John Tobin, Andrew Karolij, Michael Jenkins, Patrick McGuire and Charlotte Kaiser helped us navigate in the ‘jungle’ of global conservation finance. Hanbo Hi provided excellent research assistance in collecting macroeconomic data. Financial support by UK’s FCDO is gratefully acknowledged. We are grateful also to Roberto Buizza, Andrea Roventini, the Dasgupta Review team, and many IMF and World Bank colleagues for their useful comments. All errors are our own.
