Principles for just and effective systemic risk governance
Non-Technical Summary We are in a polycrisis – the entanglement of crises across multiple, interconnected global systems such as climate, health, and finance – that interact to produce harms significantly greater than the sum of their parts. We propose that, to mitigate and adapt to this polycrisis, strong systemic risk governance is required, and that just and effective governance requires principles. Principles help us to identify common values…
The challenge with climate-energy-economy models in constructing fair and equitable climate futures
Climate change and policy are unevenly experienced across nations, social groups, households, sectors, and generations. Understanding how benefits and burdens of climate action can be equitably shared is therefore critical. While the cornerstone concept of ‘common but differentiated responsibilities and respective capabilities’ is broadly accepted, the absence of consensus on equitable effort-sharing principles presents a challenge that permeates…
Energy and socioeconomic system transformation through a decade of IPCC-assessed scenarios
Social inequalities and the environmental crisis
Social inequalities and ecological crisis have the same historical rootsThomas Piketty (1) has described the close relationship between the development of the "extractive" economy that led to the current environmental crisis, and the origins of social inequalities in the world, between countries and within countries.Both problems date back to the era of colonialism, when massive amounts of natural and human resources were literally extracted from…

Near-term transition and longer-term physical climate risks of greenhouse gas emissions pathways
Covid-19 recovery packages can benefit climate targets and clean energy jobs, but scale of impacts and optimal investment portfolios differ among major economies
Assessing synergies and trade-offs of diverging Paris-compliant mitigation strategies with long-term SDG objectives
The Sustainable Development Goals (SDGs) and the Paris Agreement are the two transformative agendas, which set the benchmarks for nations to address urgent social, economic and environmental challenges. Aside from setting long-term goals, the pathways followed by nations will involve a series of synergies and trade-offs both between and within these agendas. Since it will not be possible to optimise across the 17 SDGs while simultaneously transit…
The cost of mitigation revisited
A multi-model analysis of long-term emissions and warming implications of current mitigation efforts
Cost reductions in renewables can substantially erode the value of carbon capture and storage in mitigation pathways
Confronting mitigation deterrence in low-carbon scenarios
Carbon dioxide removal (CDR) features heavily in low-carbon scenarios, where it often substitutes for emission reductions in both the near-term and long-term, enabling temperature targets to be met at lower cost. There are major concerns around the scale of CDR deployment in many low-carbon scenarios, and the risk that anticipated future CDR could dilute incentives to reduce emissions now, a phenomenon known as mitigation deterrence. Here we cond…
Transitional assistance policies for just, equitable and smooth low-carbon transitions
While the decarbonization of the global economy will bring immense benefits in the aggregate and to many individuals, it will also be disruptive and costly for some, at least in the short term. As these disruptions and costs have become increasingly salient in recent years, there has been an explosion of interest in the climate policy community about how low-carbon transitions can be implemented justly, equitably, and politically smoothly. A key …
The desirability of transitions in demand
An inter-model assessment of the role of direct air capture in deep mitigation pathways
The feasibility of large-scale biological CO 2 removal to achieve stringent climate targets remains unclear. Direct Air Carbon Capture and Storage (DACCS) offers an alternative negative emissions technology (NET) option. Here we conduct the first inter-model comparison on the role of DACCS in 1.5 and 2 °C scenarios, under a variety of techno-economic assumptions. Deploying DACCS significantly reduces mitigation costs, and it complements rather th…
Direct Air Carbon Capture and Sequestration
Owing to the small quantity of carbon dioxide (CO2) that can be emitted before we exceed the 1.5°C–2°C target of the Paris Agreement on climate change, we are increasingly likely to require ways of removing significant CO2 from the atmosphere. In addition to the biological options considered to date such as afforestation and bioenergy with CO2 capture, direct air carbon capture and sequestration (DACCS) is emerging as a potentially important synt…
A deep dive into the modelling assumptions for biomass with carbon capture and storage (BECCS)
Bioenergy with carbon capture and storage (BECCS) is envisaged as a critical element of most deep decarbonisation pathways compatible with the Paris Agreement. Such a transformational upscaling—to 3–7 Gt CO 2 /yr by 2050—requires an unprecedented technological, economic, socio-cultural and political effort, along with, crucially, transparent communication between all stakeholders. Integrated Assessment Models (IAMs) that underpin the 1.5 °C scena…
