Many of the technologies that can help the European Union become a net-zero emissions economy by 2050 have been shown to work but are not yet commercially competitive with incumbent fossil-fuel technologies. There is not enough private investment to drive the deployment of new low-carbon alternatives. This is primarily because carbon prices are neither high enough nor stable. There are a number of benefits from the deployment of low-carbon technologies that private firms do not factor in. These include the benefits of decreasing industry-wide costs over time, and the global climate benefits from the development of low-carbon technologies within the EU that can subsequently be exported. The result is an investment level below the socially optimal value in the EU. Commercialisation contracts could be implemented as a temporary measure to remove the risk associated with uncertain carbon prices for ambitious low-carbon projects. The aim of the contracts would be to increase private investment to the socially optimal level. Contracts would be allocated through auctions in which fixed prices for abated emissions over a fixed duration would be agreed on a project-by-project basis. On an annual basis, public subsidies amounting to the difference between the agreed carbon price and the actual EU carbon price would be provided to investors, depending on the total carbon emissions abated. As long as EU carbon prices are low, investors would receive larger subsidies to ensure their competitiveness. Contracts would be auctioned at EU level. This would generate increased competition compared to national auctions, leading to more efficient outcomes and preventing fragmentation of the single market. From about €3 billion to €6 billion would be provided to the main industrial emitting sectors annually, with the amount reducing as the EU carbon price rises and low-carbon technologies become competitive without subsidy.

This thesis explores the international political dynamics of developing low carbon technology. Specifically, Carbon Capture and Storage (CCS) technology as a climate mitigation strategy in a developing country context is examined. CCS is a technological solution that allows for the continued use of fossil fuels without the large amounts of associated CO2 emissions. This entails capturing the CO2 emitted from large point sources, such as a coal-fired power station, and transporting the captured emissions to be injected and stored permanently into geological media. Consequently, CCS is a bridging technology that could provide more time for transitioning to a low-carbon economy. A case study of India is used, which is an emerging industrialising economy, and is also the third-largest coal producer in the world. India faces a dilemma: poverty alleviation and infrastructure development to support its billion plus population requires vast amounts of energy, which is predominantly based on fossil fuels. Therefore, it was envisioned that CCS would be a sustainable option, which could enable industrialisation at the rate required, whilst preventing the exacerbation of the negative effects of climate change. However, during the period of study (2007-2010), CCS was not embraced by India, despite there being a growing impetus to develop, demonstrate and transfer the technology. India was reluctant to consider CCS as part of a mitigation strategy, and this thesis focuses on the reasons why. An interdisciplinary approach is used, coupling perspectives from science, technology and innovation studies (STS) with concepts from International Relations (IR) scholarship. This sociotechnical conceptual framework is applied to gain a more holistic picture of the failed attempt to transfer CCS technology to India. Key technical challenges and blockages are identified within India's existing energy system, which have restricted CCS technology implementation. In addition, the political challenges associated with the rejection of CCS by the Indian Government are explored. Empirical evidence is on the basis of elite interviews, an expert stakeholder survey and relevant documents. Another case study on the Cambay basin is used to further demonstrate the influence of political factors on CCS implementation, even in an area considered to have suitable technical conditions. The outcomes of this study have implications for policy addressing global challenges, especially by means of international cooperation and technological change.

This paper uses the differential game approach to construct a model of cooperative emission reduction involving the government, manufacturing firms, and retail firms under different power structures. It is found that the dominant player receives more subsidies; the development of a mechanism for horizontal technology R&D among enterprises can reduce the financial pressure on the government to implement compensation strategies and improve the effectiveness and performance of supply chain emission reduction; and the government can develop differentiated subsidy schemes to achieve Pareto optimality in the supply chain and environmental performance based on different game strategies and revenue-sharing agreements by enterprises.
