Decarbonizing the World Economy by Frank Jotzo

Members of the U.S. youth group SustainUS gathered at COP21 in Paris. Individuals painted circles around one eye to signify their support for zero emissions by 2050 to limit global warming to 1.5C. The Deep Decarbonization Pathways project has revealed that significant decarbonization is possible while growing economies by the year 2050.

In Brief The world’s carbon emissions have been flat for two years. Is this the start of global decarbonization, as is needed to fulfill the promise of the Paris climate change agreement? For this to happen, much more needs to be done than countries are currently planning. But it is possible to take the carbon out of the world economy over the coming decades, and to do so with increased economic prosperity in all countries. The four pillars of ‘decarbonization’ are energy efficiency, zero emissions electricity, replacing fossil fuels with this clean electricity in transport, building and industry, and ensuring that nature’s role as a large sink of carbon emissions is recognized. Detailed country-level studies as part of the Deep Decarbonization Pathways project show that this can be done using existing technologies. Future technological progress will make the transformation easier to achieve. The solutions differ according to countries’ circumstances, but all major countries can decarbonize while growing their economy. The macroeconomic cost of ‘deep’ decarbonization is low relative to underlying economic growth and the cost of climate change impacts. The cost is falling as technologies improve, and low-carbon technologies can bring many other benefits. To ensure that the current tapering of carbon emissions continues, we need a policy environment that enables transition of carbon intensive industries, supports the development of new clean technologies, and facilitates investment in low-carbon equipment and infrastructure. Economic policy reform for low-carbon growth can be attractive for national governments. But to achieve it, governments need to lead and embrace change. 74  |  Solutions  |  May-June 2016  |  www.thesolutionsjournal.org
