Focusing on London, UK, this paper presents evidence collected via semi-structured interviews with experts and practitioners involved in the propagation of climate emergency declarations to critically explore how and why these declarations emerged, and the various different roles they are perceived to play for different local actors.

Multilateral development institutions often use performance-based allocation (PBA), mathematical formulas based on a list of performance criteria, to inform the allocation of development assistance or environmental funding. The way the formulas are designed can have material and often unintended consequences on the allocation of funds; this paper highlights a particular problem called the ‘cardinal fallacy’. Read more

The number of climate change laws in major economies has grown from less than 40 in 1997 to almost 500 at the end of 2013. The passage of these laws is influenced by both domestic and international factors. This paper reviews the main international factors, drawing on a powerful new dataset of climate legislation in 66 national jurisdictions. We find that the propensity to legislate on climate change is heavily influenced by the passage of similar laws elsewhere, suggesting a strong and so far under-appreciated role for international policy diffusion.

This study explores the distributional impacts of a net-zero-consistent carbon price across different household types and income deciles in the UK; and examines which combination of interventions may reduce carbon consumption and still be progressive. The authors find that it is possible to design a revenue recycling scheme that leaves fuel-poor and low-income households better off while driving the transition to net-zero emissions in the UK by 2050.

National governments, with development partners, have an important role to play in supporting adaptation and climate-resilient development among private actors – households, producers and small businesses – in the semi-arid lands of developing countries, argues this brief, a final output from the Pathways to Resilience in Semi-Arid Economies (PRISE) project.

Policy - 2017

Ongoing concerns about the best policies to achieve affordability have led to three reviews: of energy costs, of the Levy Control Framework, and of carbon pricing. This paper draws on research findings and empirical evidence to identify key principles and issues that should be taken into account by the Government in relation to these separate but related reviews.

Adaptation presents developing countries with the ultimate dual challenge – building a rapidly evolving, sustainable economy within an environment increasingly altered by the impacts of climate change. To meet this challenge, adaptation policy must find balance and create synergy between the two, as climate resilience and economic resilience go hand in hand. Read more

Shifting from coal to natural gas for electricity generation can help the UK power sector to decarbonise in the near term. With good planning and investment, natural gas can support the development of a low-carbon power sector by providing essential backup for intermittent renewables, but could only play a bigger role longer-term if fitted with carbon capture and storage (CCS) technology.

However, a new UK ‘dash’ for gas on the assumption of low prices is a risky economic and environmental option. A lower risk option is a ‘dash’ for smart gas; using natural gas in those areas where it offers the greatest value in decarbonising the power sector. Read more
