Decarbonizing Development


Book Description

The science is unequivocal: stabilizing climate change implies bringing net carbon emissions to zero. This must be done by 2100 if we are to keep climate change anywhere near the 2oC warming that world leaders have set as the maximum acceptable limit. Decarbonizing Development: Three Steps to a Zero-Carbon Future looks at what it would take to decarbonize the world economy by 2100 in a way that is compatible with countries' broader development goals. Here is what needs to be done: -Act early with an eye on the end-goal. To best achieve a given reduction in emissions in 2030 depends on whether this is the final target or a step towards zero net emissions. -Go beyond prices with a policy package that triggers changes in investment patterns, technologies and behaviors. Carbon pricing is necessary for an efficient transition toward decarbonization. It is an efficient way to raise revenue, which can be used to support poverty reduction or reduce other taxes. Policymakers need to adopt measures that trigger the required changes in investment patterns, behaviors, and technologies - and if carbon pricing is temporarily impossible, use these measures as a substitute. -Mind the political economy and smooth the transition for those who stand to be most affected. Reforms live or die based on the political economy. A climate policy package must be attractive to a majority of voters and avoid impacts that appear unfair or are concentrated on a region, sector or community. Reforms have to smooth the transition for those who stand to be affected, by protecting vulnerable people but also sometimes compensating powerful lobbies.




Renewable Energy Sources and Climate Change Mitigation


Book Description

This Intergovernmental Panel on Climate Change Special Report (IPCC-SRREN) assesses the potential role of renewable energy in the mitigation of climate change. It covers the six most important renewable energy sources - bioenergy, solar, geothermal, hydropower, ocean and wind energy - as well as their integration into present and future energy systems. It considers the environmental and social consequences associated with the deployment of these technologies, and presents strategies to overcome technical as well as non-technical obstacles to their application and diffusion. SRREN brings a broad spectrum of technology-specific experts together with scientists studying energy systems as a whole. Prepared following strict IPCC procedures, it presents an impartial assessment of the current state of knowledge: it is policy relevant but not policy prescriptive. SRREN is an invaluable assessment of the potential role of renewable energy for the mitigation of climate change for policymakers, the private sector, and academic researchers.




Legal Pathways to Deep Decarbonization in the United States


Book Description

Legal Pathways to Deep Decarbonization in the United States provides a "legal playbook" for deep decarbonization in the United States, identifying well over 1,000 legal options for enabling the United States to address one of the greatest problems facing this country and the rest of humanity. The book is based on two reports by the Deep Decarbonization Pathways Project (DDPP) that explain technical and policy pathways for reducing U.S. greenhouse gas emissions by at least 80% from 1990 levels by 2050. This 80x50 target and similarly aggressive carbon abatement goals are often referred to as deep decarbonization, distinguished because it requires systemic changes to the energy economy. Legal Pathways explains the DDPP reports and then addresses in detail 35 different topics in as many chapters. These 35 chapters cover energy efficiency, conservation, and fuel switching; electricity decarbonization; fuel decarbonization; carbon capture and negative emissions; non-carbon dioxide climate pollutants; and a variety of cross-cutting issues. The legal options involve federal, state, and local law, as well as private governance. Authors were asked to include all options, even if they do not now seem politically realistic or likely, giving Legal Pathways not just immediate value, but also value over time. While both the scale and complexity of deep decarbonization are enormous, this book has a simple message: deep decarbonization is achievable in the United States using laws that exist or could be enacted. These legal tools can be used with significant economic, social, environmental, and national security benefits. Book Reviews "A growing chorus of Americans understand that climate change is the biggest public health, economic, and national security challenge our families have ever faced and they rightly ask, ''What can anyone do?'' Well, this book makes that answer very clear: we can do a lot as individuals, businesses, communities, cities, states, and the federal government to fight climate change. The legal pathways are many and the barriers are not insurmountable. In short, the time is now to dig deep and decarbonize." --Gina McCarthy, Former U.S. Environmental Protection Agency Administrator "Legal Pathways to Deep Decarbonization in the United States sets forth over 1,000 solutions for federal, state, local, and private actors to tackle climate change. This book also makes the math for Congress clear: with hundreds of policy options and 12 years to stop the worst impacts of climate change, now is the time to find a path forward." --Sheldon Whitehouse, U.S. Senator, Rhode Island "This superb work comes at a critical time in the history of our planet. As we increasingly face the threat and reality of climate change and its inevitable impact on our most vulnerable populations, this book provides the best and most current thinking on viable options for the future to address and ameliorate a vexing, worldwide challenge of extraordinary magnitude. Michael Gerrard and John Dernbach are two of the most distinguished academicians in the country on these issues, and they have assembled leading scholars and practitioners to provide a possible path forward. With 35 chapters and over 1,000 legal options, the book is like a menu of offerings for public consumption, showing that real actions can be taken, now and in the future, to achieve deep decarbonization. I recommend the book highly." --John C. Cruden, Past Assistant Attorney General, Environment and Natural Resources Division, U.S. Department of Justice "This book proves that we already know what to do about climate change, if only we had the will to do it. The path to decarbonization depends as much on removing legal impediments and changing outdated incentive systems as it does on imposing new regulations. There are ideas here for every sector of the economy, for every level of government, and for business and nongovernmental organizations, too, all of which should be on the table for any serious country facing the most serious of challenges. By giving us a sense of the possible, Gerrard and Dernbach and their fine authors seem to be saying two things: (1) do something; and (2) it''s possible. What a timely message, and what a great collection." --Jody Freeman, Archibald Cox Professor of Law and Founding Director of the Harvard Law School Environmental and Energy Law Program




Southeast Asia and the Economics of Global Climate Stabilization


Book Description

Climate change is a global concern of special relevance to Southeast Asia, a region that is both vulnerable to the effects of climate change and a rapidly increasing emitter of greenhouse gases (GHGs). This study focuses on five countries of Southeast Asia that collectively account for 90% of regional GHG emissions in recent years---Indonesia, Malaysia, the Philippines, Thailand, and Viet Nam. It applies two global dynamic economy–energy–environment models under an array of scenarios that reflect potential regimes for regulating global GHG emissions through 2050. The modeling identifies the potential economic costs of climate inaction for the region, how the countries can most efficiently achieve GHG emission mitigation, and the consequences of mitigation, both in terms of benefits and costs. Drawing on the modeling results, the study analyzes climate-related policies and identifies how further action can be taken to ensure low-carbon growth.




Negative Emissions Technologies and Reliable Sequestration


Book Description

To achieve goals for climate and economic growth, "negative emissions technologies" (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change. Unlike carbon capture and storage technologies that remove carbon dioxide emissions directly from large point sources such as coal power plants, NETs remove carbon dioxide directly from the atmosphere or enhance natural carbon sinks. Storing the carbon dioxide from NETs has the same impact on the atmosphere and climate as simultaneously preventing an equal amount of carbon dioxide from being emitted. Recent analyses found that deploying NETs may be less expensive and less disruptive than reducing some emissions, such as a substantial portion of agricultural and land-use emissions and some transportation emissions. In 2015, the National Academies published Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration, which described and initially assessed NETs and sequestration technologies. This report acknowledged the relative paucity of research on NETs and recommended development of a research agenda that covers all aspects of NETs from fundamental science to full-scale deployment. To address this need, Negative Emissions Technologies and Reliable Sequestration: A Research Agenda assesses the benefits, risks, and "sustainable scale potential" for NETs and sequestration. This report also defines the essential components of a research and development program, including its estimated costs and potential impact.




Accelerating Decarbonization of the U.S. Energy System


Book Description

The world is transforming its energy system from one dominated by fossil fuel combustion to one with net-zero emissions of carbon dioxide (CO2), the primary anthropogenic greenhouse gas. This energy transition is critical to mitigating climate change, protecting human health, and revitalizing the U.S. economy. To help policymakers, businesses, communities, and the public better understand what a net-zero transition would mean for the United States, the National Academies of Sciences, Engineering and Medicine convened a committee of experts to investigate how the U.S. could best decarbonize its transportation, electricity, buildings, and industrial sectors. This report, Accelerating Decarbonization of the United States Energy System, identifies key technological and socio-economic goals that must be achieved to put the United States on the path to reach net-zero carbon emissions by 2050. The report presents a policy blueprint outlining critical near-term actions for the first decade (2021-2030) of this 30-year effort, including ways to support communities that will be most impacted by the transition.




Getting to Net-Zero Emissions: Lessons from Latin America and the Caribbean


Book Description

All Latin America and the Caribbean countries have ratified the Paris Agreement, which aims to limit global warming to between 1.5C and 2C above pre-industrial levels. Those goals require reaching net-zero carbon dioxide emissions by around 2050 and substantial reductions of CO2 emissions by 2030. Getting to Net-Zero Emissions takes stock of the lessons learnt from the experiences of country teams implementing the ongoing IDB-led Deep Decarbonization Pathways in Latin America and the Caribbean Project and proposes approaches to developing and delivering long-term pathways to net-zero emissions by 2050. The report shows the essential role played by long-term strategies in terms of identifying and planning the deployment of the infrastructure and policy packages necessary to ensure a just transition towards a net-zero emission economy. Long-term strategies will help governments anticipate fiscal and financial costs, manage trade-offs, minimize social impacts, and define the sequence of policy reforms and investment priorities required to deliver a carbon-neutral future. The design of long-term strategies by 2020 in line with the timeline envisaged in the context of the Paris Agreement can guide the establishment of more ambitious Nationally Determined Contributions (NDCs) and minimize stranded assets and associated costs. Long-term strategies are an essential instrument, both to contribute to the redirection of public and private investments, and to guide the dialogue with development institutions seeking to support sustainable and inclusive development. By reading this report, we hope that decision makers and technicians will gain insights into how to deliver decarbonization successfully.

Climate Stabilization Targets


Book Description

Emissions of carbon dioxide from the burning of fossil fuels have ushered in a new epoch where human activities will largely determine the evolution of Earth's climate. Because carbon dioxide in the atmosphere is long lived, it can effectively lock the Earth and future generations into a range of impacts, some of which could become very severe. Emissions reductions decisions made today matter in determining impacts experienced not just over the next few decades, but in the coming centuries and millennia. According to Climate Stabilization Targets: Emissions, Concentrations, and Impacts Over Decades to Millennia, important policy decisions can be informed by recent advances in climate science that quantify the relationships between increases in carbon dioxide and global warming, related climate changes, and resulting impacts, such as changes in streamflow, wildfires, crop productivity, extreme hot summers, and sea level rise. One way to inform these choices is to consider the projected climate changes and impacts that would occur if greenhouse gases in the atmosphere were stabilized at a particular concentration level. The book quantifies the outcomes of different stabilization targets for greenhouse gas concentrations using analyses and information drawn from the scientific literature. Although it does not recommend or justify any particular stabilization target, it does provide important scientific insights about the relationships among emissions, greenhouse gas concentrations, temperatures, and impacts. Climate Stabilization Targets emphasizes the importance of 21st century choices regarding long-term climate stabilization. It is a useful resource for scientists, educators and policy makers, among others.




Pathways to Low-carbon Development for the Philippines


Book Description

This study assesses how the growth of the Philippines can be made climate friendly through a detailed modeling approach that draws on extensive national stakeholder input. The Philippines currently has a low level of per capita greenhouse gas emissions. However, emission levels are growing at an increasing rate, with 4% annual growth between 2006 and 2012. The country's energy system is becoming more carbon intensive to satisfy escalating energy demand caused by strong economic growth. This study assesses how the Philippines can take a low-carbon pathway by drawing on detailed modeling of the power, residential, and transport sectors. It identifies low-carbon development options that can be deployed at approximately zero net cost to reduce energy sector greenhouse gas emissions by 70% by 2050. With energy use levels still low, the country has an opportunity to follow a low-carbon development trajectory--if action is taken soon.
