Report sets out key priorities to meet 2050 net zero target

Policy actions and solutions to help the UK to reach its 2050 net zero target have been outlined in a new paper by leading UK scientists.

The report, Net-Zero Solutions and Research Priorities in the 2020s, is published by the COP26 Universities Network and brings together 26 leading scientists from 10 UK universities, led by the University of Cambridge.

It sets out key solutions and policy actions that should be implemented now, as well as priority research areas for the next decade, which will be crucial to reducing emissions in order to meet the Paris Agreement goals.

Research in the 2020s must be prioritised into solutions for sectors that are particularly difficult to decarbonise, such as aviation, electricity generation and storage, and maritime shipping, says the report.

It also highlights net zero solutions which could be implemented now, such as the electrification of road freight, hydrogen produced using renewable energy instead of current carbon-intensive methods, and changes to land use planning to prioritise denser, mixed-use, low traffic neighbourhoods.

Additional solutions highlighted in the report include the retrofitting of buildings, increased R&D investment to bring low-carbon farming practices to market, and the deployment of Carbon Capture Utilisation and Storage (CCUS) at scale by the mid-2020s to support the first low-carbon and net zero industrial clusters.

The report comes at a critical time ahead of the United Nations COP26 Climate Change Summit, which takes place in Glasgow this November.

“It is abundantly clear from the recent IPCC report that the 2020s will be the crucial decade to reduce emissions in order to meet the Paris Agreement goals, and the decisions made at COP26 will be critical in achieving that,” said co-lead author Dr Erik Mackie from Cambridge Zero, the University’s climate initiative. “This cross-disciplinary report will aid decision-makers by identifying the key actions that we must take now, and the priority areas where we should urgently focus our research efforts to tackle hard-to-decarbonise sectors.”

The paper highlights net-zero solutions in eight priority sectors, setting out actions to take now, research priorities for the next decade, and future benefits for each sector. These are:

  • Electricity (generation, storage, system and networks)
  • Buildings
  • Road transport
  • Industry
  • Land/sea use and agriculture
  • Aviation and shipping
  • Waste
  • Greenhouse Gas Removal (GGR)

Nature-based Solutions (NbS) – key actions that can work with nature to address climate change and biodiversity loss across all sectors, while also supporting economic recovery – are highlighted separately.

“The coming decade will be about action and implementation, and we need to focus on solutions that can be practically implemented before 2030 – our report highlights some of these solutions for each of our priority sectors, many of which will have co-benefits due to their interdisciplinary nature,” said co-lead author Dr Elizabeth Tennyson, Marie-Curie Research Fellow in Cambridge’s Cavendish Laboratory. “No single sector is the solution: many sectors need to work in parallel in order to get to net zero. We hope this policy brief will not only influence change but also encourage further innovations.”

The authors stress that each solution should be assessed with respect to greenhouse gas emissions reductions, energy efficiency and societal implications to provide a basis for developing long-term policies, maximising positive impact of investment and research effort, and guiding industry investors in safe and responsible planning.

“It is great to see this group of universities pooling their expertise and coming to a broad consensus view about the needs for research and immediate actions in the fight against climate change,” said co-author Professor David Cebon from Cambridge’s Department of Engineering, who leads the Centre for Sustainable Road Freight.
