National development banks (NDBs) and development finance institutions – domestically focused, publicly owned financial institutions with a specific development mandate – are poised to play a role in bridging the investment gap for climate-compatible infrastructure in developing countries.

The investment choices make in the coming years will either lock-in a climate-compatible, inclusive growth pathway, or a high-carbon, inefficient and unsustainable pathway for decades to come.

Embracing new technologies that could enable drastic reductions in GHG emissions will be key to delivering low-emissions pathways for growth, but it is not always obvious what the big breakthroughs will look like.

Investments in water and sanitation are a prerequisite to deliver on the Sustainable Development Goals (SDGs), in particular on SDG 6 ensuring availability and sustainable management of water and sanitation for all.

Based on an in-depth literature review and responses to a survey among OECD member countries, this paper discusses the use of flexibility mechanisms in environmental regulations.

This paper provides a concrete example of how policy analysts can use empirical programme evaluation studies to perform ex-post assessments of environmentally related tax policies.

Plastics are an important material in the economy but present a challenge for waste management, resource efficiency and the environment. Low rates of recycling and high rates of environmental leakage represent key sustainability challenges for plastics as well as product designers and producers.

Climate change and outdoor air pollution are two of the most challenging environmental issues that modern society faces. These challenges are strongly linked through their emission sources, the sectors they affect and the policies that can be implemented to reduce emissions.

This paper presents the potential benefits and challenges of enhanced international co-ordination on carbon pricing and outlines the different types and levels of co-ordination that are available for national and sub-national governments.

Large-scale catastrophic and smaller recurrent disasters generate considerable economic losses. Over the past thirty years, damages from major disasters have increased significantly.
