The science is clear: climate change is a fact and the probability is extremely high that it has been caused by humans. At the same time, policy responses are hesitant, rather lukewarm and differ substantially between nation-states. The question is, what drives and what blocks radical action? This book makes the case that institutional settings, path dependence and emerging change coalitions are critical in explaining climate policies across the global political economy. Technological and social-political innovations are key drivers for dealing with climate change. This class of innovation is very much guided, or suppressed, by a national economy's established institutional settings. By anchoring national case studies in a version of the well established ‘varieties of capitalism’ approach, the chapters of this book show why some economies are policy leaders and others become policy followers, or even policy interlockers. Moreover, the case studies demonstrate the extent to which external events and institutional constraints from the international polity influence national innovation strategies. Taking a unique analytical approach, which combines insights from innovation policies and a variety of capitalism literature, the authors provide genuine comprehension of the interplay between institutional settings, political actors and climate policies. National Pathways to Low Carbon Emission Economies offers a valuable examination of these issues on climate change that will be of interest to academics and postgraduates researching climate policy, economic policy and social movements. Furthermore, it is relevant for policy analysts and policy makers who are interested in learning from climate policies in the context of innovation strategies for a range of countries.

The Federal Government of Nigeria has adopted an ambitious strategy to make Nigeria the world’s 20th largest economy by 2020. Sustaining such a pace of growth will entail rapid expansion of the level of activity in key carbon-emitting sectors, such as power, oil and gas, agriculture and transport. In the absence of policies to accompany economic growth with a reduced carbon foot-print, emissions of greenhouse gases could more than double in the next two decades. This study finds that there are several options for Nigeria to achieve the development objectives of vision 20:2020 and beyond, but stabilizing emissions at 2010 levels, and with domestic benefits in the order of 2 percent of GDP. These benefits include cheaper and more diversified electricity sources; more efficient operation of the oil and gas industry; more productive and climate –resilient agriculture; and better transport services, resulting in fuel economies, better air quality, and reduced congestion. The study outlines several actions that the Federal Government could undertake to facilitate the transition towards a low carbon economy, including enhanced governance for climate action, integration of climate consideration in the Agriculture Transformation Agenda, promotion of energy efficiency programs, scale-up of low carbon technologies in power generation (such as renewables an combined cycle gas turbines), and enhance vehicle fuel efficiency.

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.

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.

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

Climate change resulting from CO2 and other greenhouse gas emissions poses a huge threat to human welfare. To contain that threat, the world needs to cut emissions by about 50 per cent by 2050, and to start cutting emissions now. A global agreement to take action is vital. A fair global deal will require the UK to cut emissions by at least 80 per cent below 1990 levels by 2050. In this report, the Committee on Climate Change explains why the UK should aim for an 80 per cent reduction by 2050 and how that is attainable, and then recommends the first three budgets that will define the path to 2022. But the path is attainable at manageable cost, and following it is essential if the UK is to play its fair part in avoiding the far higher costs of harmful climate change. Part 1 of the report addresses the 2050 target. The 80 per cent target should apply to the sum of all sectors of the UK economy, including international aviation and shipping. The costs to the UK from this level of emissions reduction can be made affordable - estimated at between 1-2 per cent of GDP in 2050. In part 2, the Committee sets out the first three carbon budgets covering the period 2008-22, and examines the feasible reductions possible in various sectors: decarbonising the power sector; energy use in buildings and industry; reducing domestic transport emissions; reducing emissions of non-CO2 greenhouse gases; economy wide emissions reductions to meet budgets. The third part of the report examines wider economic and social impacts from budgets including competitiveness, fuel poverty, security of supply, and differences in circumstances between the regions of the UK.
