From least-cost to SDG-optimal sectoral allocation of Paris Agreement-compatible mitigation efforts
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…
Cost-optimal vs. policy-driven scenarios for a decarbonised European energy system
The European Union’s (EU) climate strategy, anchored in the European Green Deal, the Fit-for-55 package, and the updated National Energy and Climate Plans (NECPs), requires a rapid transformation of the energy system to meet the legally binding target of net-zero greenhouse gas emissions by 2050 and a 55% reduction by 2030 relative to 1990 levels. Yet, how national plans align with EU-wide ambition, alongside the implications for investment, infr…
Energy and socioeconomic system transformation through a decade of IPCC-assessed scenarios
A window of (missed) opportunity? A comprehensive stocktake and energy-system impact assessment of global Covid-19 recovery packages
COVID-19 reshaped global economic priorities at the time, with recovery packages offering unprecedented fiscal stimuli aimed at revitalising economies from the impacts of the pandemic and associated policy responses—including lockdowns. While these packages were quickly framed as an opportunity for aligning socioeconomic recovery spending with near- and longer-term climate goals, early assessments of their decarbonisation footprint were constrain…
A multimodel analysis of post-Glasgow climate targets and feasibility challenges
Navigating through an energy crisis
Covid-19 recovery packages can benefit climate targets and clean energy jobs, but scale of impacts and optimal investment portfolios differ among major economies
A multi-model analysis of long-term emissions and warming implications of current mitigation efforts
The desirability of transitions in demand
The importance of stakeholders in scoping risk assessments—Lessons from low-carbon transitions
Pathways for the transition of the Polish power sector and associated risks
In Poland, coal has been a key driver of energy security and, despite its declining role, still accounts for most of the country's power generation mix. Transition potential for the fossil fuel-based power sector can be reflected in a heated debate between a coal-oriented, evolutionary process of slowly reducing emissions; and a more ambitious renewable energy-driven pathway. Both pathways feature barriers; some are evident in standard economic a…
Integrated policy assessment and optimisation over multiple sustainable development goals in Eastern Africa
Heavy reliance on traditional biomass for household energy in eastern Africa has significant negative health and environmental impacts. The African context for energy access is rather different from historical experiences elsewhere as challenges in achieving energy access have coincided with major climate ambitions. Policies focusing on household energy needs in eastern Africa contribute to at least three sustainable development goals (SDGs): cli…
Contested energy futures, conflicted rewards? Examining low-carbon transition risks and governance dynamics in China's built environment
China's urbanisation has caused city populations to grow rapidly, boosting continuous development and scaling up the construction industry more intensely. The building sector is thus a key area to consider for climate change mitigation efforts. This study initially seeks to explore the development of a green transition pathway for the Chinese building sector, informed by national and local low-carbon policies and strategies, with specific referen…
Identifying optimal technological portfolios for European power generation towards climate change mitigation
Barriers to and consequences of a solar-based energy transition in Greece
In Greece, the renewable energy potential and a low-quality building stock constitute the background of a possible low-carbon energy transition. This transition, however, faces significant uncertainties, ranging from long-term effects of the ongoing economic recession and technological lock-ins, to the stability of the regulatory framework and issues of public acceptance. Such uncertainties may eventually give rise to significant barriers to, as …
