Title: A multi-model study of energy supply investments in Latin America under climate control policy

In this article we investigate energy supply investment requirements in Latin America until 2050 through a multi-model approach as jointly applied in the CLIMACAP-LAMP research project. We compare a business-as-usual scenario needed to satisfy anticipated future energy demand with a set of scenarios that aim to significantly reduce CO 2 emissions in the region. We find that more than a doubling of annual investments, in absolute terms, occurs in the business-as-usual scenario between 2010 and 2050, while investments may treble over the same time horizon when climate policies are introduced. However, investment costs as a share of GDP decline over time in the business-as-usual scenario, as well as the climate policy scenarios, due to the fast economic growth in that region. Business-as-usual cumulative investments of 1.4 trillion US$ are anticipated between 2010 and 2050 in energy supply, and increase when additional climate policies are introduced: under a carbon tax of 50 $/tCO 2e in 2020 increasing with a rate of 4% per year, an additional 0.6 trillion US$ (+45%) investment is needed. Climate control measures lead to increased investment in low-carbon electricity technologies, primarily wind, solar, and CCS applied to fossil fuels and biomass. Our analysis suggests that compared tomore » the business-as-usual case an average additional 21 billion US$ per year of electricity supply investments is required in Latin America until 2050 under a climate policy aiming at 2°C climate stabilization. Conversely, there is a disinvestment in fossil fuels. For oil production, a growth from 58 billion US$ to 130 billion US$ annual investment by 2050 is anticipated in a business-as-usual scenario: ambitious climate policy reduces this to 28 billion US$. Finally, mobilizing necessary additional investment capital, in particular for low-carbon technologies, will be a challenge, and suitable frameworks and enabling environments for a scale-up in public and private investment will be critical to help reach required levels. The economic case for such a transition still remains to be articulated.« less
