The UK energy system is changing rapidly. Greenhouse gas emissions fell by 43% between 1990 and 2017, and renewables now account for 30% of electricity generation. Despite this progress, achieving emissions reductions has been difficult outside the electricity sector, and progress could stall without more effective policy action. The Paris Agreement means that the UK may have to go further than current targets, to achieve a net zero energy system. Reducing emissions is not the only important energy policy goal. Further, progress need to be made whilst minimising the costs to consumers and taxpayers; maintaining high levels of energy security; and maximising economic, environmental and social benefits. There is a clear need for research to understand the nature of the technical, economic, political, environmental and societal dynamics affecting the energy system - including the local, national and international components of these dynamics. This proposal sets out UKERC's plans for a 4th phase of research and engagement (2019-2024) that addresses this challenge. It includes a programme of interdisciplinary research on sustainable future energy systems. This is driven by real-world energy challenges whilst exploring new questions, methods and agendas. It also explains how UKERC's central activities will be developed further, including new capabilities to support energy researchers and decision-makers. The UKERC phase 4 research programme will focus on new challenges and opportunities for implementing the energy transition, and will be concerned with the three main questions: - How will global, national and local developments influence the shape and pace of the UK's transition towards a low carbon energy system? - What are the potential economic, political, social and environmental costs and benefits of energy system change, and how can they be distributed equitably? - Which actors could take the lead in implementing the next stage of the UK's energy transition, and what are the implications for policy and governance? To address these questions, the research programme includes seven interrelated research themes: UK energy in a global context; Local and regional energy systems; Energy, environment, and landscape; Energy infrastructure transitions; Energy for mobility; Energy systems for heat; and Industrial decarbonisation. The proposal sets out details of research within these themes, plans for associated PhD studentships and details of the flexible research fund that will be used to commission additional research projects, scoping studies and to support integration. A first integration project on energy and the economy will be undertaken at the start of UKERC phase 4. The research themes are complemented by four national capabilities that form part of the research programme: an expanded Technology and Policy Assessment (TPA) capability; a new Energy Modelling Hub; the UKERC Energy Data Centre; and a new Public Engagement Observatory. Research within TPA and the Observatory will align and integrate with the main research themes. These four capabilities will also enhance UKERC's ability to provide evidence, data and expertise for academic, policy, industry and other stakeholder communities. The UKERC headquarters (HQ) team will support the management and co-ordination of the research programme; and will also undertake a range of other functions to support the broader UK energy research community and its key stakeholders. These functions include promoting networking and engagement between stakeholders in academia, policy, industry and third sector (including through a networking fund), supporting career development and capacity building, and enhancing international collaboration (including through the UK's participation in the European Energy Research Alliance).

Observed, Strategic, sustained action is now needed to avoid further negative consequences of climate change and to build a greener, cleaner and fairer future. According to the Intergovernmental Panel on Climate Change the rise in global temperature is largely driven by total carbon dioxide emissions over time. In order to avoid further global warming, international Governments agreed to work towards a balance between emissions and greenhouse gas removal (GGR), known 'net zero', in the Paris Agreement. In June 2019 the UK committed to reaching net zero emissions by 2050, making it the first G7 country to legislate such a target. Transitioning to net zero means that we will have to remove as many emissions as we produce. Much of the focus of climate action to date has been on reducing emissions, for example through renewable power and electric vehicles. However, pathways to net zero require not just cutting fossil fuel emissions but also turning the land into a net carbon sink and scaling up new technologies to remove and store greenhouse gases. This will require new legislation to pave the way for investment in new infrastructure and businesses expected to be worth billions of pounds a year within 30 years. This challenge has far-reaching implications for technology, business models, social practices and policy. GGR has been much less studied, developed and incentivised than actions to cut emissions. The proposed CO2RE Hub brings together leading UK academics with a wide range of expertise to co-ordinate a suite of GGR demonstration projects to accelerate progress in this area. In particular the Hub will study how we can (1) reduce technology costs so that GGR becomes economically viable; (2) ensure industry adopts the concept of net zero in a way that will maintain and create jobs; (3) put in place sensible policy incentives; (4) make sure there is social license for GGR (unlike fracking or nuclear); (5) set up regulatory oversight of environmental sustainability and risks of GGR; (6) understand what is required to achieve GGR at large scale and (7) guarantee there are the skills and knowledge required for all this to happen. Building on extensive existing links to stakeholders in business, Government and NGOs, the Hub will work extensively with everyone involved in regulating and delivering GGR to ensure our research provides solutions to strategic priorities. We will also encourage the teams working on demonstrator technologies to think responsibly about the risks, benefits and public perceptions of their work and consider the full environmental, social and economic implications of implementation from the outset. CO2RE will seek to bring the GGR community in the UK as a whole closer together, functioning as a gateway to UK inter-disciplinary research expertise on GGR. We will inform, and stay informed, about the latest developments nationally and internationally, and reach out to engage the wider public. In doing so we will be able to respond to a rapidly evolving landscape recognising that technical and social change are not separate, but happen together. To accelerate and achieve meaningful change, we will be guided by consultation with key decision-makers and the general public, and set up a £1m flexible fund to respond to priorities that emerge with the help of the wider UK academic community. Ultimately we will help the UK and the world understand how GGR can be scaled up responsibly as part of climate action to meet the ambition of net zero.
