Analysis and Use of Information and Communication Tools in Economics of Climate Change
Full text linkThe use of Information and Communication Technologies (ICT) in the context of climate change is of great importance in the scientific community, but can also play an important role in the policy context. On the one hand, the results achievable for mitigation and adaptation are influencing the policy arena, and on the other hand these instruments represent an opportunity for decision-makers to apply innovative forms of public administration based on stakeholder involvement, which can reduce the existing gap between policy-makers and citizens (Oates, 2003). The paper provides an analysis of the main ICT tools and methods used in climate change economics by means of a questionnaire-based survey and focus group discussion with specific experts in this context. The issues addressed are related with the use and relevance of ICT in the different research area of climate change, the perceived usefulness of these tools, and their importance in the scientific, economic and policy contexts. The main problems and limitations of ICT are investigated, together with their potential role in future research.Climate change, Information and Communication Technologies tools (ICT)
Linking Reduced Deforestation and a Global Carbon Market: Impacts on Costs, Financial Flows, and Technological Innovation
Full text linkDiscussions of tropical deforestation are currently at the forefront of climate change policy negotiations at national, regional, and international levels. This paper analyzes the effects of linking Reduced Emissions from Deforestation and Forest Degradation (REDD) to a global market for greenhouse gas emission reductions. We supplement a global climate-energy-economy model with alternative cost estimates for reducing deforestation emissions in order to examine a global program for stabilizing greenhouse gas concentrations at 550 ppmv of CO2 equivalent. Introducing REDD reduces global forestry emissions through 2050 by 20-22% in the Brazil-only case and by 64-88% in the global REDD scenario. At the same time, REDD lowers the total costs of the climate policy by an estimated 10-25% depending on which tropical countries participate and whether the “banking†of excess credits for use in future periods is allowed. As a result, REDD could enable additional reductions of at least 20 ppmv of CO2-equivalent concentrations with no added costs compared to an energy-sector only policy. The cost savings from REDD are magnified if banking is allowed and there is a need to increase the stringency of global climate policy in the future in response, for example, to new scientific information. Results also indicate that REDD will decrease carbon prices in 2050 by 8-23% with banking and 11-26% without banking. While developing regions, particularly Latin America, gain the value of REDD opportunities, the decrease in the carbon price keeps the value of international carbon market flows relatively stable despite an increase in volumes transacted. We also estimate that REDD generally reduces the total portfolio of investments and research and development of new energy technologies by 1-10%. However, due to impacts on the relative prices of different fossil fuels, REDD has a slight positive estimated effect on investments in coal-related technologies (IGCC and CCS) as well as, in some cases, non-electric energy R&D. This research confirms that integrating REDD into global carbon markets can provide powerful incentives for the preservation of tropical forests while lowering the costs of global climate change protection and providing valuable policy flexibility.Climate change, deforestation, carbon sinks
