“Investing $6.9 trillion per year in clean infrastructure between 2016 and 2030 in G20 countries would help limit global temperature rise to below 2 degrees Celsius as agreed by world leaders in Paris in 2015. The additional investment cost could be offset by annual fuel savings of $1.7 trillion from more energy-efficient technologies and infrastructure,” The Organisation for Economic Co-operation and Development (OECD) report.
Keeping global warming below 2C would limit the worst effects of sea-level rise, Arctic sea ice melting, damage to coral reefs and acidification of oceans, according to the U.N. Intergovernmental Panel on Climate Change. The G20 countries account for 80 percent of carbon dioxide emissions, a key contributor to climate change.
“Far from being a dampener on growth, integrating climate action into growth policies can have a positive economic impact,” OECD Secretary-General Angel Gurría.
Combining climate policies, such as charging polluters, with economic policies to drive growth through more environment-friendly infrastructure could increase G20 economies’ gross domestic product by up to 2.8 percent on average in 2050.
This rises to nearly 5 percent if the economic benefits of avoiding climate change impacts such as coastal flooding or storm damage are taken into account. Private sector financing is key to achieve these investments. The OECD report called on development banks and financial institutions to facilitate and support public and private investors.
