ENV GLOBAL FORUM OCT 2016 - Session 3 - Emilio La Rovere

  1. 1. Climate Change Mitigation Policy & Economic Growth: Lessons from the Brazilian Case Prof. Emilio Lèbre La Rovere Head of CentroClima/COPPE/UFRJ COPPE - Institute of Graduate Studies and Research in Engineering UFRJ - Federal University of Rio de Janeiro OECD Global Environment Forum Session 3 Environmental Degradation and Economic Growth Paris, 24 October 2016
  2. 2. MAPS PROJECT IN BRAZIL (IES-BRASIL): THE PROCESS Climate Change Mitigation Action, Plans and Scenarios (MAPS) Project: Scenario Building Process with stakeholders involvement in support to the iNDC preparation in Brazil, Chile, Colombia and Peru In Brazil, under the umbrella of the Brazilian Forum on Climate Change, a Scenario Building Team (SBT) brought together a group of experts pertaining to the government, private sector, academia and civil society. The SBT was responsible for: • Identifying the mitigation measures that would be adopted in the scenario simulations; estimating their viability and costs; and selecting the hypotheses for their adoption during the period The Research and Modelling Team, coordinated by CentroClima at the Institute of Post-graduate Studies and Research in Engineering (COPPE) at the Federal University of Rio de Janeiro (UFRJ), was responsible for: • Processing the selected mitigation measures and input data in mathematical models and analysing the implications for the Brazilian economy

A hybrid computable general equilibrium model:  Double accounting top-down framework  monetary values  physical values (toe, tons, pass.km, tons.km)  Up to 19 productive sectors:  6 energy: biomass, oil, coal, natural gas, petroleum refining products, electricity  7 industrial (steel, non-ferrous, cement, paper and pulp, chemicals, mining, other industrial sectors)  2 transportation (passenger, load)  4 other (agriculture, livestock, construction, services)  Up to 6 income classes  Interaction with bottom-up sectoral models The IMACLIM-BR model
  6. 6. THE SCENARIOS TO ASSIST UNDERSTANDING OF THE RESULTS • The scenarios are exploratory • They are not forecasts of the most probable future • They are resultant of a series of premises chosen by the experts and researchers involved in a participative manner • The Governmental Plan Scenario was strongly based on the long-term National Energy Plan 2050 GOVERNMENT PLAN SCENARIO (GPS) MEASURES ALREADY BEING IMPLEMENTED UNDER THE NATIONAL CLIMATE CHANGE PLAN ADDITIONAL MITIGATION 1 (AM1) EXPANSION OF MEASURES CONSIDERED IN THE GPS, PLUS ADDITIONAL MEASURES ADDITIONAL MITIGATION 2 (AM2) EARLY IMPLEMENTATION OR EXPANSION OF MEASURES FROM AM1, PLUS ADDITIONAL MEASURES
  7. 7. SCENARIOS WITH A GLOBAL CARBON TAX During the course of the project, the IES-Brasil team analysed what might happen, should a worldwide carbon pricing strategy be adopted. This was explored by considering a carbon tax on the burning of fossil fuels. As such, two additional scenarios were simulated: AM1+T adopting the same mitigation measures as those tested in AM1 in addition to a global carbon tax of US$ 20/tCO2 AM2+T adopting the same mitigation measures as those tested in AM2 in addition to a global carbon tax of US$ 100/tCO2

  9. 9. RESULTS – ECONOMIC & SOCIAL IMPLICATIONS The unemployment rate falls across all additional mitigation scenarios, compared to GPS. This is a result of a higher level of labour intensive activities (e.g. reforestation and renewable energy). In the scenarios with a global carbon tax, this is due to the hypothesis adopted by the SBT, that the revenues from the carbon tax offset the reduction of labour taxes in order to stimulate job creation. UNEMPLOYMENT RATE (%) 4.35% 4.08% 4.20% 3.50% 3.81% AM2GPS AM1 AM1+T AM2+T
  10. 10. RESULTS – ECONOMIC & SOCIAL IMPLICATIONS GROSS DOMESTIC PRODUCT (GDP) Trillion US$ (2005 constant) In the scenarios that do consider a global carbon tax, GDP grows slightly less than in the GPS, but in additional mitigation scenarios implemented without a global carbon tax, then GDP growth is higher than in the GPS. 2.14 5.55 5.59 5.54 5.68 5.46 2005 AM2GPS AM1 AM1+T AM2+T
  11. 11. RESULTS – ECONOMIC & SOCIAL IMPLICATIONS Even in the scenarios that consider a global carbon tax, there is also an increase in the average annual household income as a result of the increasing employment rate. The difference in relation to the scenarios that do not consider a carbon tax, is that consumption for Class 3 actually falls slightly in AM2+T, due to the fact that the richest are more affected by the adoption of carbon pricing. HOUSEHOLD CONSUMPTION BY INCOME CLASS (BRL - 2005 constant) 1,959 3,629 3,621 3,844 4,847 8,650 8,772 9,077 18,594 37,601 38,025 39,010 3,652 3,688 8,680 8,686 37,704 37,590 2005 GPS AM1 Class 2 (to 2 - 10 MW) Classe 3Class 1 (to 2 MW) AM2+TAM2+T AM2 Class 3 (10+ MW) 2005 GPS AM1 AM2+TAM2+T AM2 2005 GPS AM1 AM2+TAM2+T AM2
  12. 12. CONCLUSIONS: ECONOMIC AND SOCIAL IMPLICATIONS Even in a scenario of high economic growth it is possible to reduce emissions considerably by 2030, thanks to the reduction witnessed in the emissions/GDP ratio. The ratio between emissions and GDP (measured in tCO2eq/million US$ of 2005), which was halved from 2 to 1 tCO2eq per US$ million between 2005 and 2010, would be 0.7 in the GPS, 0.5 in AM1, and 0.4 in AM2, in 2030 PARTIAL DECOUPLING OF GDP GROWTH AND GHG EMISSIONS (2005=100) GPS AM1 AM2 GDP Population GHG Emissions
