Decarbonising The World's Economy: Assessing The Feasibility Of Policies To Reduce Greenhouse Gas Emissions


Book Description

Too often amongst policy makers and thought leaders an assumption is made that we must make a choice between tackling climate change and having a strong economy; tackling climate change and allowing poorer nations to develop; tackling climate change and having a secure energy system. However, a decade of advanced modelling tested against historical data has provided wide evidence that well-chosen policies can be implemented that avoid these apparent either/or choices.This highly interdisciplinary book provides an overview of potential pathways for the decarbonisation of the global economy. By examining the entire global economy, we show policy-makers and thought-leaders that greatly reducing the risks of climate change can be consistent with energy security, economic development in poor nations, and vibrant economies in already developed nations. Advanced models of the relationships between the economy, energy and climate change pioneered at the Cambridge Centre for Climate Change Mitigation Research (4CMR) over the past decade provides a sound evidence base for decisions. This book examines not only the impacts of policies, but also the feasibility of bringing them forward and the ways in which energy, climate and economic policies can and must be joined up if climate, energy and economic goals are to be met globally.Economists, physicists, engineers, policy analysts, environmental scientists, climate scientists, political analysts, lawyers and computational scientists are brought together for the first time to produce analyses that make up a unique approach to a global problem that must be addressed sooner rather than later.




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.




Greenhouse Gas Removal Technologies


Book Description

Greenhouse gas removal (GGR) technologies can remove greenhouse gases such as carbon dioxide from the atmosphere. Most of the current GGR technologies focus on carbon dioxide removal, these include afforestation and reforestation, bioenergy with carbon capture and storage, direct air capture, enhanced weathering, soil carbon sequestration and biochar, ocean fertilisation and coastal blue carbon. GGR technologies will be essential in limiting global warning to temperatures below 1.5°C (targets by the IPCC and COP21) and will be required to achieve deep reductions in atmospheric CO2 concentration. In the context of recent legally binding legislation requiring the transition to a net zero emissions economy by 2050, GGR technologies are broadly recognised as being indispensable. This book provides the most up-to-date information on GGR technologies that provide removal of atmosphere CO2, giving insight into their role and value in achieving climate change mitigation targets. Chapters discuss the issues associated with commercial development and deployment of GGRs, providing potential approaches to overcome these hurdles through a combination of political, economic and R&D strategies. With contributions from leaders in the field, this title is an indispensable resource for graduate students and researchers in academia and industry, working in chemical engineering, mechanical engineering and energy policy.




Tackling Climate Change Through Livestock


Book Description

Greenhouse gas emissions by the livestock sector could be cut by as much as 30 percent through the wider use of existing best practices and technologies. FAO conducted a detailed analysis of GHG emissions at multiple stages of various livestock supply chains, including the production and transport of animal feed, on-farm energy use, emissions from animal digestion and manure decay, as well as the post-slaughter transport, refrigeration and packaging of animal products. This report represents the most comprehensive estimate made to-date of livestocks contribution to global warming as well as the sectors potential to help tackle the problem. This publication is aimed at professionals in food and agriculture as well as policy makers.




Climate Intervention


Book Description

The signals are everywhere that our planet is experiencing significant climate change. It is clear that we need to reduce the emissions of carbon dioxide and other greenhouse gases from our atmosphere if we want to avoid greatly increased risk of damage from climate change. Aggressively pursuing a program of emissions abatement or mitigation will show results over a timescale of many decades. How do we actively remove carbon dioxide from the atmosphere to make a bigger difference more quickly? As one of a two-book report, this volume of Climate Intervention discusses CDR, the carbon dioxide removal of greenhouse gas emissions from the atmosphere and sequestration of it in perpetuity. Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration introduces possible CDR approaches and then discusses them in depth. Land management practices, such as low-till agriculture, reforestation and afforestation, ocean iron fertilization, and land-and-ocean-based accelerated weathering, could amplify the rates of processes that are already occurring as part of the natural carbon cycle. Other CDR approaches, such as bioenergy with carbon capture and sequestration, direct air capture and sequestration, and traditional carbon capture and sequestration, seek to capture CO2 from the atmosphere and dispose of it by pumping it underground at high pressure. This book looks at the pros and cons of these options and estimates possible rates of removal and total amounts that might be removed via these methods. With whatever portfolio of technologies the transition is achieved, eliminating the carbon dioxide emissions from the global energy and transportation systems will pose an enormous technical, economic, and social challenge that will likely take decades of concerted effort to achieve. Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration will help to better understand the potential cost and performance of CDR strategies to inform debate and decision making as we work to stabilize and reduce atmospheric concentrations of carbon dioxide.




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.




Designing Climate Solutions


Book Description

With the effects of climate change already upon us, the need to cut global greenhouse gas emissions is nothing less than urgent. It’s a daunting challenge, but the technologies and strategies to meet it exist today. A small set of energy policies, designed and implemented well, can put us on the path to a low carbon future. Energy systems are large and complex, so energy policy must be focused and cost-effective. One-size-fits-all approaches simply won’t get the job done. Policymakers need a clear, comprehensive resource that outlines the energy policies that will have the biggest impact on our climate future, and describes how to design these policies well. Designing Climate Solutions: A Policy Guide for Low-Carbon Energy is the first such guide, bringing together the latest research and analysis around low carbon energy solutions. Written by Hal Harvey, CEO of the policy firm Energy Innovation, with Robbie Orvis and Jeffrey Rissman of Energy Innovation, Designing Climate Solutions is an accessible resource on lowering carbon emissions for policymakers, activists, philanthropists, and others in the climate and energy community. In Part I, the authors deliver a roadmap for understanding which countries, sectors, and sources produce the greatest amount of greenhouse gas emissions, and give readers the tools to select and design efficient policies for each of these sectors. In Part II, they break down each type of policy, from renewable portfolio standards to carbon pricing, offering key design principles and case studies where each policy has been implemented successfully. We don’t need to wait for new technologies or strategies to create a low carbon future—and we can’t afford to. Designing Climate Solutions gives professionals the tools they need to select, design, and implement the policies that can put us on the path to a livable climate future.




Building a Low-carbon Economy


Book Description

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.




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.




Diversification and Cooperation in a Decarbonizing World


Book Description

This book is the first stocktaking of what the decarbonization of the world economy means for fossil fuel†“dependent countries. These countries are the most exposed to the impacts of global climate policies and, at the same time, are often unprepared to manage them. They depend on the export of oil, gas, or coal; the use of carbon-intensive infrastructure (for example, refineries, petrochemicals, and coal power plants); or both. Fossil fuel†“dependent countries face financial, fiscal, and macro-structural risks from the transition of the global economy away from carbon-intensive fuels and the value chains based on them. This book focuses on managing these transition risks and harnessing related opportunities. Diversification and Cooperation in a Decarbonizing World identifies multiple strategies that fossil fuel†“dependent countries can pursue to navigate the turbulent waters of a low-carbon transition. The policy and investment choices to be made in the next decade will determine these countries’ degree of exposure and overall resilience. Abandoning their comfort zones and developing completely new skills and capabilities in a time frame consistent with the Paris Agreement on climate change is a daunting challenge and requires long-term revenue visibility and consistent policy leadership. This book proposes a constructive framework for climate strategies for fossil fuel†“dependent countries based on new approaches to diversification and international climate cooperation. Climate policy leaders share responsibility for creating room for all countries to contribute to the goals of the Paris Agreement, taking into account the specific vulnerabilities and opportunities each country faces.
