This report by the Environmental Audit Committee welcomes the Government's decision to set the fourth carbon budget - required under the Climate Change Act - at the level recommended by the independent Committee on Climate Change. But it questions the Government's decision to announce a review of this budget in 2014 in response to fears that it could be bad for business. The MPs warn that the prospect of a review could weaken investor confidence in low-carbon industries as it creates uncertainty about the future trajectory of emissions reductions. In setting the fourth carbon budget, the Government announced that it would bring forward a package of measures to help energy intensive industries most at risk of so-called 'carbon leakage'. There should be a robust sector-by-sector assessment of whether jobs and production could be displaced by the UK's carbon budgets. The 2014 review could ease the budget if the UK's emissions reduction trajectory is steeper than that required by the EU's Emissions Trading System. However, the recommended carbon budgets should be regarded as an absolute minimum - less ambitious budgets would make the UK's 2050 climate change targets harder and more costly to achieve. The MPs strongly support the mandatory emissions reporting by business in order to aid transparency and illustrate the contributions that companies are making. The report also criticises Ministers for dropping plans to require Government Departments and Local Authorities to budget for the carbon emissions produced by their policies and operations.

Balancing Greenhouse Gas Budgets: Accounting for Natural and Anthropogenic Flows of CO2 and other Trace Gases provides a synthesis of greenhouse gas budgeting activities across the world. Organized in four sections, including background, methods, case studies and opportunities, it is an interdisciplinary book covering both science and policy. All environments are covered, from terrestrial to ocean, along with atmospheric processes using models, inventories and observations to give a complete overview of greenhouse gas accounting. Perspectives presented give readers the tools necessary to understand budget activities, think critically, and use the framework to carry out initiatives. - Written by a combination of experts across career stages, presenting an integrated perspective for graduate students and professionals alike - Includes sections authored by those involved in both early and later IPCC assessments - Provides an interdisciplinary resource that spans many topics and methodologies in oceanic, land and atmospheric processes

The UK's existing carbon budgets represent the minimum level of emissions reduction required to avoid a global 2 degrees temperature rise - regarded as a dangerous threshold - and the UK's leading climate scientists do not believe loosening the budgets is warranted. The current (2008-2012) and second (2013-2017) carbon budgets will be easily met because of the recession. But the UK is not on track to meet the third (2018-22) and fourth budgets (2023-2027), because not enough progress is being made in decarbonising transport, buildings and heat production. The Government's Carbon Plan - which set milestones for five key Government Departments to cut carbon - is out of date without any quarterly progress reports published yet. The Green Deal has also had low take-up rates so far. The Government should set a 2030 decarbonisation target for the power sector now, rather than in 2016 as the Energy Bill sets out. The Government should also reconsider placing a statutory duty on local authorities to produce low-carbon plans for their area. The current low-carbon price in the EU ETS - the result of the economic downturn of recent years and over-allocation of emissions permits - also means that that scheme will not deliver the emissions reductions envisaged when the fourth carbon budget was set. Without any tightening of the EU ETS increased pressure will therefore be placed on the non-traded sector, which will have to produce further emissions reductions to cover the emerging gap left by the traded sector

Although the future extent and effects of global climate change remain uncertain, the expected damages are not zero, and risks of serious environmental and macroeconomic consequences rise with increasing atmospheric greenhouse gas concentrations. Despite the uncertainties, reducing emissions now makes sense, and a carbon tax is the simplest, most effective, and least costly way to do this. At the same time, a carbon tax would provide substantial new revenues which may be badly needed, given historically high debt-to-GDP levels, pressures on social security and medical budgets, and calls to reform taxes on personal and corporate income. This book is about the practicalities of introducing a carbon tax, set against the broader fiscal context. It consists of thirteen chapters, written by leading experts, covering the full range of issues policymakers would need to understand, such as the revenue potential of a carbon tax, how the tax can be administered, the advantages of carbon taxes over other mitigation instruments and the environmental and macroeconomic impacts of the tax. A carbon tax can work in the United States. This volume shows how, by laying out sound design principles, opportunities for broader policy reforms, and feasible solutions to specific implementation challenges.

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.

Although there is no denial of climate justice, there has been a persistent lack of practical joined-up actions regarding the creation of an international climate institution. However, politicians and academic researchers have been working together to find solutions. This new book is an attempt to put forward constructive approaches to climate security and justice, building upon the inputs from the wide-ranging debates that took place at the CASS Forum on Climate Justice and the Carbon Budget Approach in Beijing (April 2010). The purpose of this prestigious international conference was to construct an international climate regime and to help promote climate justice. It also called on governments, particularly governments in developed countries, to bear the historical responsibility of climate change. Climate change is a controversial topic worldwide today and the international regime and corresponding actions will inevitably have a lasting and profound influence on the world economy and international politics. At its thirteenth session, held in Bali, Indonesia, at the end of 2007, the Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC) adopted the Bali Action Plan, initiating a new process of negotiations on long-term cooperative actions under the Convention with the goal of reaching international agreements on an international climate regime beyond 2012 at the fifteenth session of the Conference to be held in Copenhagen, Denmark, at the end of 2009. The key factors in the present international climate negotiations are a shared vision of global long-term cooperative actions, mitigation, adaptation, technology and finance, and their core issue is how to reach an agreement for equitable burden-sharing of obligations for the reduction of greenhouse gas emissions or allocation of emission entitlements in accordance with the concrete conditions of various countries and to ensure the implementation of such an agreement under an appropriate international regime. As the largest developing country in the world, China plays an important role in international climate negotiations and is under increasing international pressure.The existing Kyoto Protocol model takes the level of emissions in 1990 as a base and determines the emission reduction obligations of each developed country through negotiation. The findings gathered together in this book break through the fixed pattern of thinking of the Kyoto Protocol and, based on the theory and methodology of the basic carbon emissions needed for human development, studies a carbon budget proposal for global greenhouse gas emission reductions. This proposal not only better embodies the principle of "e;common but differentiated responsibilities"e; established by the Climate Convention, but will also be able to realize global goals for mid- and long-term emission reductions. It represents a comprehensive proposal for developing a more equitable and more effective international climate regime.The CASS Forum on Climate Justice and the Carbon Budget Approach in Beijing (April 2010) was organised in association with the Institute for Urban and Environmental Studies of the Chinese Academy of Social Sciences, Konrad Adenauer Foundation and Misereor.

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.

This open access book discusses biogeochemical processes relevant to carbon and aims to provide readers, graduate students and researchers, with insight into the functioning of marine ecosystems. A carbon centric approach has been adopted, but other elements are included where relevant or needed. The book focuses on concepts and quantitative understanding of primary production, organic matter mineralization and sediment biogeochemistry. The impact of biogeochemical processes on inorganic carbon dynamics and organic matter transformation are also discussed.

Why the traditional “pledge and review” climate agreements have failed, and how carbon pricing, based on trust and reciprocity, could succeed. After twenty-five years of failure, climate negotiations continue to use a “pledge and review” approach: countries pledge (almost anything), subject to (unenforced) review. This approach ignores everything we know about human cooperation. In this book, leading economists describe an alternate model for climate agreements, drawing on the work of the late Nobel laureate Elinor Ostrom and others. They show that a “common commitment” scheme is more effective than an “individual commitment” scheme; the latter depends on altruism while the former involves reciprocity (“we will if you will”). The contributors propose that global carbon pricing is the best candidate for a reciprocal common commitment in climate negotiations. Each country would commit to placing charges on carbon emissions sufficient to match an agreed global price formula. The contributors show that carbon pricing would facilitate negotiations and enforcement, improve efficiency and flexibility, and make other climate policies more effective. Additionally, they analyze the failings of the 2015 Paris climate conference. Contributors Richard N.
