Lessons Learned on Green Stimulus

Case Studies from the Global Financial Crisis

Executive Summary

Introduction

As governments respond to the COVID-19 crisis, they can draw on lessons from the countries that used green stimulus spending to boost their economies and create jobs after the global financial crisis of 2008–09. This paper analyzes the extent to which governments, central banks, and international financial institutions implemented green stimulus in 2008–09 and the effectiveness of these measures. It examines green spending on a global level, then provides case studies from the United States, South Korea, China, and the European Union (EU). The focus is on fiscal measures rather than policy and regulatory changes.

Findings

About US$520 billion was announced for green stimulus measures in 2008–09, 16 percent of the total global fiscal stimulus. Almost 90 percent was spent by the following five economies, in the order of the amount announced: China, the United States, South Korea, Japan, and the EU. Much of this was on heavy infrastructure such as rail transportation, grid modernization, and water/waste management infrastructure (Robins et al. 2010; ILO 2011). These numbers use a broad definition of “green” stimulus, but according to a narrower definition looking only at clean energy such as building efficiency, renewable power, and smart grids, roughly $177 billion was announced (Liebreich et al. 2010). In addition to fiscal policy, many of the world’s central banks responded with aggressive monetary policy, including quantitative easing. However, these monetary policies did not target green sectors and have been criticized as maintaining the high-carbon status quo (Matikainen et al. 2017).

Given the available evidence, our four case studies and high-level global assessments conclude that green stimulus spending did help economies recover and did create jobs. The economic and emissions effects of green investments in stimulus packages are difficult to measure, but the few ex post analyses that have been conducted conclude that the green elements of stimulus packages in the United States, South Korea, China, and the EU had a positive effect on gross domestic product (GDP) and employment (see Table ES-1).

Country

Evaluations

United States

• The American Recovery and Reinvestment Act (ARRA) supported 900,000 job-years (full-time jobs over one year) in clean energy fields from 2009 to 2015 (Council of Economic Advisors 2016).

• Each $1 million of green ARRA investments created 15 new jobs, which arose mostly from 2013 to 2017 (Popp et al. 2020).

• The ARRA was successful in stimulating job creation in renewable and energy efficiency sectors (Lim et al. 2020).

South Korea

• South Korea’s unemployment rate in 2009 was 3.6%, compared to projections of 4.3% if it hadn’t been for the stimulus. Short-term public employment increased by a net 165,000 jobs in 2009 (OECD 2010).

• South Korea’s Green Growth Plan directly created 156,000 new green jobs from 2009 to 2011 (Korean Development Institute, cited in Jung 2015).

• The South Korean economy recovered from the economic crisis faster than expected, with green stimulus measures a key contributor (Mundaca and Damen 2015).

China

• The rapid investment in rail and grid networks and other green initiatives in China led to a large and immediate boost to GDP, around 4.2% above the baseline in 2009 and 3.6% above the baseline in 2010 (Pollitt 2011).

EU

• The green elements of the stimulus packages had a small positive impact on European countries’ economies in the short run. Each $1 in green investment boosted GDP by $0.60 to $1.10 at the national level and up to $1.50 at the European level. Most green investment policies also led to higher employment levels (Pollitt 2011).

In many cases green stimulus was as effective or more effective at creating jobs than spending on fossil fuels or traditional stimulus. U.S. stimulus spending on public transit led to 70 percent more jobs than equivalent spending on highways (Smart Growth America 2011). U.S stimulus spending on coastal habitat restoration created far more jobs than investing in fossil fuels would have (Edwards et al. 2013). In South Korea, non-stimulus investments in renewable energy projects were estimated to create more jobs per dollar than its stimulus spending on dams (Chang et al. 2012). The economic literature corroborates this evidence. According to the International Energy Agency (IEA) (2020), investing $1 million in building efficiency, clean urban transport, or solar photovoltaics (PV) would create more than twice as many gross jobs as investing $1 million in coal or gas power. Restoration and sustainable forest management, electric vehicle charging infrastructure, biofuels, walking and cycling infrastructure, and recycling have also been identified to have high employment multipliers (IEA 2020; Edwards et al. 2013; Blythe et al. 2014; Garrett-Peltier 2011).

In the longer run, investment in clean energy manufacturing and research after the global financial crisis helped countries build up new industries. The United States, China, and Germany became renewable energy leaders in part because of programs coming out of the Great Recession (Varro et al. 2020). In the United States, the share of wind turbine equipment manufactured domestically rose from 25 percent in 2006–07 to 72 percent in 2012 (Mundaca and Richter 2015). China’s solar PV manufacturing capacity increased by a factor of 20 between 2007 and 2011 (Earth Policy Institute 2015).

Some green interventions were more popular than others. Ten countries allocated stimulus spending to building efficiency, seeing retrofits as low-hanging fruit to quickly stimulate the economy. Evaluations from the United Kingdom and the United States find that building retrofits created jobs and saved households money on energy bills (Oak Ridge National Laboratory 2015a, 2015b; Nottingham Trent University 2013). At least eight countries implemented car-scrapping schemes, but they only had a modest effect on consumer demand and did not reduce emissions as much as was hoped. Nature-based solutions such as restoration and sustainable agriculture were largely untapped, but the few projects that were undertaken were promising.

There were disparities in the speed with which countries were able to disburse green stimulus, and in some cases not all the spending that was announced materialized. For example, the United States spent 89 percent of the green stimulus that it initially allocated, while Australia only spent 34 percent (Tienhaara 2018). For many countries, a lack of transparency makes it challenging to hold governments accountable for their green spending. In the United States and Europe, more complex projects like high-speed rail and carbon capture and storage proceeded slowly or failed. China and South Korea were able to quickly begin construction of infrastructure projects, but in some cases that was because these were projects that had been planned already, or because the governments relaxed environmental regulations. Some of the projects were not as green as they appeared, including China’s funding for rail and grid infrastructure that supported coal use, or a river restoration project in South Korea that built new dams and had a questionable environmental impact.

The international financial institutions and national development banks increased their lending significantly during the 2008–09 economic crisis, including some for renewable energy. The European Investment Bank in particular made climate change central to its finance strategy in that time period. Still, there is no comprehensive assessment from these institutions of the proportion of the overall finance that was green versus polluting.

Global emissions fell during the economic contraction but rebounded strongly after the recovery. This could be because green investments may take time to have an impact on emissions, because of the relatively small size of green spending compared to total stimulus packages, or because of the lack of broader structural reforms to other parts of the economy that were incentivizing emissions. For example, the world spent 15 times more on fossil fuel subsidies from 2009 to 2013 than it did on the clean energy stimulus that was disbursed in that time period (Liebreich et al. 2010; IEA 2016, 2019). Early projections when the stimulus packages were being implemented estimated that green stimulus in the United States, China, and Europe would decrease emissions and energy use compared to the baseline in the long term (US EIA 2009; WWF 2010; Pollitt 2011); however, there have been no ex post counterfactual analyses, so it is impossible to form firm conclusions about the emissions impact of the green stimulus measures.

Key Recommendations

Drawing on the lessons from the global financial crisis, the following are recommendations for governments to implement green stimulus as part of the COVID-19 recovery:

  • 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.
  • Governments should clearly define what projects they consider to be green as well as be transparent on disbursement of finance.
  • Governments should focus on projects that can scale up quickly to create short-term GDP and employment gains while avoiding untested technologies and more complicated infrastructure projects. Where possible they should focus on scaling up existing projects rather than designing new ones.
  • Stimulus alone cannot set the world on a trajectory for a net-zero emissions economy, so it should be accompanied by other policies and fiscal and regulatory reforms, such as phasing out fossil fuel subsidies and use, introducing carbon pricing, and setting emissions targets and standards.
  • Governments should undertake more monitoring and evaluation and plan for ex post assessments to understand the economic and environmental impacts of different stimulus measures.
