Hydrogen is a cross-cutting energy vector that can help to decarbonise various end-use sectors. At least two-thirds of the global hydrogen production is projected to be green hydrogen by 2050, supporting the transition to a net-zero emissions global energy system. This paper presents a value...

Reducing air pollution is a major policy challenge, especially in densely populated urban areas where human exposure to emissions is considerable. This paper develops and examines a series of scenarios for the evolution of transport-related emissions in the area of Santiago, Chile. The analysis...

Achieving climate-resilient economies and societies will not only require increasing the billions of financial flows for adaptation, but also shifting broader -- public and private -- financial flows and investment away from potentially mal-adapted activities towards those that contribute to...

Air pollution is a global challenge to people’s health and has severe economic consequences. The region of Northeast Asia is no exception. Across most regions in Japan, and in the entire territories of Korea and China, annual average concentrations of fine particulate matter are above the...

This paper analyses existing methodologies developed by commercial services providers, research institutes or civil society organisations for investors and financial institutions, to assess the alignment of their assets and portfolios with the Paris Agreement temperature goal. The analysis is...

The fuel efficiency of conventional private vehicles is a key input in the design of several economic and environmental policies. Reliable projections of the fuel efficiency variable can improve estimates on the future emission savings from policies promoting vehicle replacement, and on future...

Women’s participation in environmental decision-making is important for advancing both gender equality and environmental action. The presence of women in political decision-making is linked to more ambitious climate goals and policies. Women on corporate boards consistently prioritise...

Trade in plastic waste and scrap plays a potentially important role in helping to strengthen markets for recycled plastics as it can help to achieve economic efficiency through for instance economies of scale. But such trade has also been criticised for leading to plastic pollution when...

This paper provides estimates of the cost of preventing land-based plastic leakage into the ocean, covering 38 OECD member countries and 10 selected major plastic waste emitters in Asia and Africa. The study estimates capital costs at EUR 54 billion in the Moderate Ambition scenario and EUR 74...

This paper assesses the role of carbon pricing in a sustainable recovery from COVID-19. It tracks the policy changes in carbon pricing within OECD and G20 countries between January 2020 and August 2021 of the COVID-19 pandemic. Carbon pricing as defined here includes emissions trading schemes,...
