A reaffirmed commitment to fighting climate change has set Canada on a greener course, but the country needs to quickly implement planned measures to reduce the carbon intensity of its energy industry, particularly in oil sands, and green its transport sector in order to progress towards its 2030 emissions goals, according to a new OECD report.

This paper analyses the reform undertaken by Iceland to avert a looming crisis and restore fish stocks to sustainable levels; and outlines the process involved in designing and implementing this reform. It also reflects on the challenges encountered and the environmental, economic and social impacts of the reform. This country study draws on the OECD report "The Political Economy of Biodiversity Policy Reform".

This paper summarises efforts in two West African countries – Mauritania and Guinea-Bissau – to mobilise international finance to sustain the marine biodiversity upon which fisheries depend, and to establish conservation trust funds. The countries study draws on the 2017 OECD report The Political Economy of Biodiversity Policy Reform.

This Policy Paper summarises key messages about the economic case for water investment, the barriers to investment and the financing gap. It charts a course for action to better value water and to facilitate water investment at scale. The Roundtable on Water Financing, a joint initiative of the OECD, the World Water Council and the Netherlands, will continue to deepen the evidence base and broaden engagement on these issues.

This report examines what would be needed to achieve zero CO2 emissions from international maritime transport by 2035. It assesses measures that can reduce shipping emissions effectively and describes possible decarbonisation pathways that use different combinations of these measures; and reviews under which conditions these measures could be implemented and presents concrete policy recommendations.

The OECD proposes to conduct a first-of-its-kind review of Indonesia’s green growth policies, with the co-operation of four Ministries.

This Policy Paper comprises the Background Report prepared by the OECD for the G7 Environment, Energy and Oceans Ministers (19-21 September, Canada). It provides an overview of current plastics production and use, the environmental impacts that this is generating and identifies the reasons for currently low plastics recycling rates, as well as what can be done about it.

This Policy Paper comprises an Issue Brief and Background Report prepared by the OECD for the G7 Environment, Energy and Oceans Ministers (19-21 September 2018, Canada). It outlines the rising risks faced by coastal communities, which are being exacerbated by climate change; and shows how governments can harness innovation to help improve resilience and emphasises the need for close engagement with coastal communities.

Public support for metal extraction and processing has received little attention relative to that for the agriculture, energy, or fisheries sectors. This report addresses this knowledge gap by mapping out the most common forms of support provided for primary metals (produced from mineral ores) and secondary metals (produced from scrap).

This paper explores the consequences on the labour markets of structural changes induced by decarbonisation policies. These policies are likely going to have consequences on labour-income distribution given i) existing rigidities in the labour markets, and ii) their different impacts on sectors and on job categories.

This report investigates the effects of select climate policies, non-climate policies, as well as political economy factors on the decarbonisation of electricity in OECD countries from 2000 to 2015. Effects are analysed on the three phases of decarbonisation: (1) increasing the share of renewables installed, (2) increasing the use of renewables in generation, and (3) reducing the emissions from electricity.

Meeting the temperature goals of the Paris Agreement requires a transformational change in our infrastructure systems. This working paper aims to shed light on the extent to which current electricity generation projects under construction at the global level - the "pipeline" - are consistent with what a low-carbon transition requires.

A co-ordinated policy response is needed to ensure that new and existing infrastructure networks are resilient to climate change. This Policy Paper outlines a framework for achieving this based on the experiences in OECD and G20 countries. It shows how governments and businesses can collaborate to mobilise investment for climate-resilient infrastructure.

This report provides an overview of methodologies to evaluate the effectiveness of policy instruments for biodiversity, covering impact evaluation, cost-effectiveness analysis and other more commonly used approaches. It also provides an inventory of biodiversity-relevant impact evaluation studies, across both terrestrial and marine ecosystems.

Extended producer responsibility is a policy approach that aims to increase waste recovery and recycling. Extended producer responsibility systems aim to make producers responsible for the environmental impacts of their products throughout the product chain, from design to the end-of-life phase. This report focuses on free-riding of producers or retailers, which the fast expansion of online sales in recent years has been exacerbating.

The purpose of this study is to investigate the effect of congestion pricing on the demand for clean transport modes. It draws on an empirical analysis of the effect of Milan’s congestion charge on the use of bike sharing. The analysis indicates that congestion pricing increases daily bike-sharing use by at least 5% in the short term.

Parking policies have significant environmental and economic implications, which have often been left unconsidered. This paper reviews the relevant literature to provide a deeper understanding of the main environmental and economic consequences of common parking policies, and suggest policy options to protect the environment and increase social welfare.

This report offers a guide on potential reform pathways towards sustainable agriculture water use, based on a thorough review of selected past water and agriculture reforms and extensive consultation with policy experts.

This paper shows how women and men may use infrastructure differently according to their needs, social roles or preferences; and provides a framework to help countries align their infrastructure policies and projects with other societal and environmental goals, including supporting gender equality.

Rapid economic development and climate change are increasing our vulnerability to natural disasters, and a new joint OECD-World Bank report calls for pro-active management of the financial costs of those disasters before they strike.

To support government efforts to transition to a more sustainable ocean economy, the OECD is mobilising expertise across multiple policy fronts, covering environmental, economic, financial and social dimensions.

Fossil-fuel subsidies are environmentally harmful, costly, and distortive. After a 3 years downward trend between 2013 and 2016, government support for fossil fuel production and use has risen again, in a threat to efforts to curb greenhouse gas emissions and air pollution, and the transition to cleaner and cheaper energy.

Statistics by sector and by country based on DAC Members’ reporting on the Environment Policy Marker.

At their Summit in Osaka this weekend, G20 leaders agreed on a range of priorities for which analysis and support from the OECD and other international organisations are playing a crucial role.

Climate change and outdoor air pollution are two of the most challenging environmental issues that modern society faces. This paper presents the first global analysis of the joint economic consequences of climate change and outdoor air pollution to 2060, in the absence of new policies to address these challenges.

Policy instruments can be applied to improve the sustainability of plastics, including regulations, market-based instruments, information and voluntary tools. The report reviews the use of these instruments, provides good practice examples, such as product taxes and charges, eco-design standards, extended producer responsibility and environmental product labels, as well as discussing opportunities for their future applications.

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. A number of studies credibly identify causal effects of environmentally related tax policies, but do not necessarily provide all the information needed to fully inform the policy-making process.

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. This report looks at how blockchain technology can be applied to support sustainable infrastructure investment that is aligned with climate change objectives.

This paper focuses on how national and sub-national governments can align subnational financial flows to transition towards low-carbon, resilient and inclusive cities. The paper is a contribution from the OECD Champion Mayors for Inclusive Growth initiative and to the OECD Programme on Subnational Finance and Investment.

Taxing polluting sources of energy is an effective way to curb emissions that harm the planet and human health, and the income generated can be used to ease the low-carbon transition for vulnerable households. Yet 70% of energy-related CO2 emissions from advanced and emerging economies are entirely untaxed, offering little incentive to move to cleaner energy, according to a new OECD report.

National development banks (NDBs) and development finance institutions are poised to play a role in bridging the investment gap for climate-compatible infrastructure in developing countries. This paper highlights the role of NDBs drawing from case studies of the Brazilian Banco Nacional de Desenvolvimento Econômico e Social and the Development Bank of Southern Africa.

Secretary-General Angel Gurría addresses the Lord Mayor of Copenhagen and others to discuss highlights of the forthcoming OECD report on local green growth, as part of our efforts to develop more effective tools for measuring cities’ progress and monitoring the impact of green policies.

Noted actors in development share their views on what progress has been made from the past 50 years, the remaining challenges and the way toward a more efficient future in development.

Chile's OECD membership presents challenges both in the context of changing patterns of production and consumption, and in the framework of a more sustainable economy. Specifically, green growth emphasizes improving growth rates, particularly through greening existing industries, as well as through new eco-businesses.

Secretary-General Angel Gurría launched the 2012 Development Co-operation Report “Lessons in linking sustainability and development” at the 48th High Level Meeting of the Development Assistance Committee in London.

This report presents, for the first time a local ‘green growth’ indicator framework. This indicator framework was developed from the OECD ‘green growth’ strategy at the national level, but modified to highlight issues of transition that are most relevant for local areas.

Two new OECD reports provide wide-ranging evidence of how reforming subsidies and tax breaks for fossil fuels can help countries boost finances and meet green objectives.

A new OECD report presents around 550 measures that support fossil-fuel production or use in the OECD’s 34 member countries and also highlights the successes and challenges in bringing about reform, says this OECD Insights blog post.

Long-term projections suggest that without policy changes, the continuation of business-as-usual economic growth and development will have serious impacts on natural resources and the ecosystem services on which human well-being depends.

To benefit fully from cross-border trade in electricity, interconnected countries need to establish a non-discriminatory trading regime based on co-operation and co-ordination, says this study of trade in renewables-based electric power in Europe.

Ports are the nervous system of global trade. Over 80% of world cargo (by volume) is transported by sea. Our efforts to raise the efficiency, competitiveness and sustainability of ports can help boost trade, growth and jobs. It can also help us to promote green growth and development in the poorest regions, said OECD Secretary-General.

Boosting private sector investment in sustainable transport infrastructure will be essential as governments seek to meet long-term economic and environmental objectives at a time of constrained public finances, according to a new OECD report.

Cities can generate growth and jobs while becoming greener – this is the message of the OECD’s new Green Growth in Cities report. Drawing on case studies of Paris, Chicago, Kitakyushu and Stockholm, the report identifies green policies that can respond to urban growth priorities and suggests how to implement and finance them.

This paper discusses the results of the 2011-2012 OECD LEED study of measuring green growth in the Benelux countries (Belgium, The Netherlands and Luxembourg). The study paid particular attention to the challenges of measuring the transition to a low-carbon economy in cross-border areas as they have additional levels of complexity when it comes to measuring and monitoring their low-carbon transition.

People care for the environment, and a large majority state that they are willing to make compromises to green their lifestyle according to a new OECD survey of 12,000 households. However, the economic crisis has taken its toll, and the survey shows that the environment is slipping down on the list of people’s priorities.

With 7 billion people in the world today and 9 billion by 2050, we must invest in development that will meet the growing demands for food, water and energy. The new OECD publication Putting Green Growth at the Heart of Development suggests that these investments could define a path for inclusive growth and sustainable development by focusing on people’s needs and prospects while respecting the environment.

Credible and consistent carbon pricing must be the cornerstone of government actions to tackle climate change, according to a new OECD report.
