Negative Emissions Technologies for Climate Change Mitigation provides a comprehensive introduction to the full range of technologies that are being researched, developed and deployed in order to transition from our current energy system, dominated by fossil fuels, to a negative-carbon emissions system. After an introduction to the challenge of climate change, the technical fundamentals of natural and engineered carbon dioxide removal and storage processes and technologies are described. Each NET is then discussed in detail, including the key elements of the technology, enablers and constraints, governance issues, and global potential and cost estimates. This book offers a complete overview of the field, thus enabling the community to gain a full appreciation of NETs without the need to seek out and refer to a multitude of sources.

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.

"Humans started adding fossil CO2 to the atmosphere about 300 years ago and accelerated land use emissions by expanding croplands and pastures. The unintended consequence of these activities is a 120 ppm increase in atmospheric concentration of CO2, which is now changing our climate. In response, international action is being taken to reduce net greenhouse gas emissions and limit global warming below 2°C. Most climate mitigation technologies are intended to decrease the rate at which we take additional carbon from fossil fuel reservoirs and ecosystems and add it to the atmosphere as CO2. These include renewable electricity, increased energy efficiency, and carbon capture and storage of emissions from fossil power plants. This report focuses on the reverse: technologies that take CO2 out of the atmosphere and put it back into geologic reservoirs and terrestrial ecosystems. These negative emissions technologies, or NETs, have received much less attention by researchers than traditional mitigation technologies"--Preface.

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 will be an indispensable resource for graduate students and researchers in academia and industry, working in chemical engineering, mechanical engineering and energy policy.

Carbon dioxide capture and storage (CCS) is a technology aimed at reducing greenhouse gas emissions from burning fossil fuels during industrial and energy-related processes. CCS involves the capture, transport and long-term storage of carbon dioxide, usually in geological reservoirs deep underground that would otherwise be released to the atmosphere. Carbon dioxide capture and storage offers important possibilities for making further use of fossil fuels more compatible with climate change mitigation policies. The largest volumes of CO2 could be captured from large point sources such as from power generation, which alone accounts for about 40 per cent of total anthropogenic CO2 emissions. The development of capture technologies in the power generation sector could be particularly important in view of the projected increase in demand for electricity in fast developing countries with enormous coal reserves (IEA 2002a). Although, this prospect is promising, more research is needed to overcome several hurdles such as important costs of capture technology and the match of large capture sources with adequate geological storage sites. The book will provide a comprehensive, detailed but non-specialist overview of the wide range of technologies involved in carbon dioxide capture and sequestration. Focuses on technology rather than regulation and cost Covers both traditional and cutting edge capture technology Contains an abundance of case-studies an worked out examples Insight into CSS technical processes

Our oceans are suffering under the impacts of climate change. Despite the critical role that oceans play in climate regulation, international climate law and the law of the sea are developed as two different, largely separate, legal regimes. The main objective of this book is to assess how the law of the sea can be interpreted, developed and applied to support the objectives of the United Nations Climate Regime. By identifying the potential and constraints of the law of the sea regime in supporting and complementing the climate regime in the mitigation of and adaptation to climate change, this book offers a new perspective on the law of the sea and its capacity to evolve to respond to systemic challenges, and its potential to adapt and ensure a resilient and sustainable future.
