Lessons Learned on Green Stimulus

Case Studies from the Global Financial Crisis

Recommendations

Drawing on the lessons from this paper and its case studies, the following are recommendations for governments to implement green stimulus as part of the COVID-19 recovery. Countries around the world have a chance to build back better after COVID-19 by designing stimulus packages that quickly create jobs and improve the economy, while also providing climate and social cobenefits.

  • Governments should prioritize green investments that have strong economic and social benefits and have the potential to reduce emissions rather than prioritize fossil fuel investments. Existing ex post evaluations as well as our case studies find that the green elements of stimulus packages generally boosted economies and increased employment. Green investments often have higher employment multipliers than fossil fuels and will not lock in future emissions. Some green infrastructure projects can be implemented quickly to boost the economy now while other investments like research and development can create longer-term engines of growth. Governments should make sure workers receive fair wages and should support fossil fuel communities in transition.
  • Governments should be as specific as possible about what interventions they consider “green” and what types of projects will be financed. Definitions of green finance should be rigorous and internationally consistent where possible. The EU taxonomy for sustainable activities would be a good example to follow. After stimulus measures are announced, governments should continue to provide information about how the money is disbursed.
  • Governments should focus on technologies that are ready for expansion and on projects that can scale up quickly, such as energy efficiency retrofits, while avoiding untested technologies like carbon capture and storage and more complicated infrastructure projects that could run into planning difficulties, like high-speed rail. Where possible, governments should focus on scaling up existing projects rather than designing new ones.
  • Stimulus should be accompanied by other policies and fiscal reforms, such as phasing out fossil fuel subsidies and use, introducing carbon pricing, and setting emissions targets and standards. The experience from the Great Recession shows that stimulus alone cannot set the world on a trajectory for a net-zero emissions economy, though it can help build up the low-carbon infrastructure that forms the foundation for that economy.
  • Development bank finance should prioritize green investments in future stimulus packages, especially green and sustainable infrastructure. Development banks should make sure policy-based and financial intermediary lending at least “do no harm” and preferably are climate-positive, as these two instruments are expected to be major foci during the COVID-19 response. Moreover, development banks should encourage recipient countries to enact jobs programs that have strong climate cobenefits, such as nature-based solutions.
  • Central banks should set up green asset purchase programs. Central bank quantitative programs that allocate purchases according to the makeup of the market are not “neutral” and in fact give preference to emissions-intensive sectors and companies.
  • Governments should undertake more monitoring and evaluation than they did in 2008–09 stimulus packages and plan for ex post assessments to understand the economic and environmental impacts of different stimulus measures. These evaluations should consider the net life cycle effects of economic and emissions changes rather than the gross effects. There need to be more counterfactual analyses that compare a scenario with the stimulus to a scenario without it. These assessments can help with decision-making while projects are being implemented and produce valuable information for future investments.
  • Sector-specific recommendations:
    • Governments can invest in building efficiency programs to create jobs, reduce emissions, and save households money. They work best by ramping up existing programs and providing comprehensive retrofit options that could be tailored for individual home needs.
    • While public transit ridership is down because of the COVID pandemic, public transit investments can be a quick way to create jobs and support the future economy. Walking and cycling investments have also proved to have high employment multipliers.
    • Investing in renewables can create jobs, build new industries, and reduce technology prices. Renewable energy investments are an even more attractive investment today than in 2008–09, and governments can also invest in clean energy manufacturing and research in the next generation of technologies, like green hydrogen and batteries.
    • Governments, especially in low- and middle-income countries, can turn to nature-based solutions more, making sure to conduct environmental assessments beforehand. Nature-based solutions like habitat restoration were largely untapped after the global financial crisis, but the results were promising.
    • Governments should steer clear of car-scrapping schemes, which in the past have only had a modest stimulus effect and did not reduce emissions as much as was hoped.
