Emissions trading is central to the Government's efforts to reduce greenhouse gas emissions in the UK. This inquiry examines the prospects for a global carbon market and the implications of this for further development of the European Union Emissions Trading System (EU ETS). It reviews the impact and future prospects for the EU ETS in meeting the Government's twin objectives of reducing emissions at lowest cost and setting a carbon price that delivers investment in low-carbon technologies. The EU ETS has emissions caps set too high to force emitters to make the often costly investment decisions which would reduce emissions. The recession has only served to loosen what little constraint the cap provided. The carbon price has been too low to encourage the necessary investment in low-carbon processes and infrastructure. The cap mechanism therefore needs to be significantly tightened. This should be supported by cancelling 'new entrant reserve' allowances and auctioning as many allowances as possible, rather than giving them away for free (with the revenues possibly hypothecated to climate change measures). The Government should explore the possible use of a carbon tax. It should also encourage more use of allowance auctions with reserve prices, more use of incentives for low-carbon power generation and emissions performance standards for electricity generation. The emphasis should also be on harmonising the approach internationally, and on extending effective emissions trading systems. The Committee lists 19 conclusions and recommendations.

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.

Upsetting the Offset engages critically with the political economy of carbon markets. It presents a range of case studies and critiques from around the world, showing how the scam of carbon markets affects the lives of communities. But the book doesn't stop there. It also presents a number of alternatives to carbon markets which enable communities to live in real low-carbon futures.

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.
