RESEARCH SYNTHESIS BRIEF Reducing climate risk: Climate change mitigation and bioenergy Avoiding dangerous climate change requires ambitious ac- tions to sharply reduce greenhouse gas emissions. SEI works to inform, support and advise decision-makers and civil society on ways to achieve these reductions and build a low-carbon future – including the role of bioenergy. We have also built tools and analytical frameworks to explore the options, from the global to the local level. Key insights SEI’s research on climate mitigation is broad and diverse, with significant contributions to both the scientific community and policy discourses around the world, as well as capacity devel- opment. The insights discussed here provide a sampling of the range of our work. • Sub-national climate policy should focus on sectors where local actors can exert the most influence and the potential for abatement is greatest; in cities, that is likely to be trans- port and buildings. Sub-national governments can provide an important labora- tory for climate policy innovation, and with rapid urbanization around the world, city-scale mitigation efforts are ever more crucial. Building on SEI’s history of analysing GHG abate- ment opportunities for U.S. states (e.g. Massachusetts), SEI has worked with local governments to better gauge their emissions and find effective mitigation options. © Flickr / Washington State Department of Transportation © Flickr / Washington Seattle and Washington State have worked to reduce transport-related For example, SEI’s work with King County stands as one of the emissions by improving public transit options and encouraging cycling. most comprehensive analyses of local-scale emissions to date (Erickson et al. 2012). From that research, SEI built a detailed new fossil-fuel infrastructure is slated to come online by 2017 to framework for local governments to track emissions (Erickson lock in what remains of our carbon budget. and Lazarus 2012) and informed the local government network ICLEI’s primary reporting framework in its U.S. Community An SEI project launched in 2013 explores the implications of Protocol. SEI then worked with officials in Seattle to develop this disconnect between climate policy debates, and energy an in-depth, detailed scenario for how the city might achieve its development – especially in countries that are focusing on goal of carbon-neutrality, identifying ways to cut emissions by green growth.
