Rapid population growth, ageing infrastructure and new weather risks are straining the ability of cities in OECD countries to provide clean water and to protect against floods and droughts, according to a new OECD report. Cities will need large-scale investment and more effective tariffs and taxes to pay for upgrades to water systems.

2015 is a critical year for humanity. Our civilisation has never faced such existential risks as those associated with global warming, biodiversity erosion and resource depletion. Our societies have never had such an opportunity to advance prosperity and eradicate poverty. We have the choice to either finally embark on the journey towards sustainability or to stick to our current destructive “business-as-usual” pathway.

Poland has combined robust economic growth with reducing some of the pressures on its environment since it joined the EU in 2004. It has also brought environmental laws closer to European norms. Poland now needs to lessen its economy’s reliance on fossil fuels and make growth greener, according to a new OECD report.

According to shocking new research by Oxfam, the world’s richest 1% would, on current trends, own more than half the world’s wealth by 2016.

Ministers from OECD’s 34 member countries today welcomed the new OECD Principles on Water Governance, which set standards for more effective, efficient and inclusive design and implementation of water policies, and encouraged governments to put them into action.

The OECD’s Annual Meeting at Ministerial Level reinforced member governments’ support across a broad range of key OECD work.

Governments are under-utilising taxation as a tool to curb the environmental consequences of energy use, foregoing revenue and weakening their attack on the principal source of greenhouse gas emissions responsible for climate change and air pollution, according to new OECD analysis.

Taxes are potentially among the most effective ways of cutting pollution and greenhouse gas emissions, but they are currently – with very few exceptions – underused; and even where used, they are frequently designed in a sub-optimal way.

Building on the experience of OECD countries, this report sets out how the latest economic evidence and tools can enable better policy making for climate change adaptation.

Raw materials are essential for the global economy and future development depends on their continued supply. Like fossil fuels, minerals are non-renewable. In general, their deposits in the Earth’s crust are also geographically clustered, making security of supply a potential risk. The purpose of this report is to perform for the first time an analysis of critical minerals for the OECD countries as a whole.

Government support to fossil fuel consumption and production in OECD countries and key emerging economies remains high, at USD 160-200 billion annually, according to a new OECD report. This support is hampering global efforts to curb emissions and combat climate change.

Cost-benefit analyses and other quantitative appraisals are used in many countries to support decision-making in public policy, including investment projects in sectors such as transport and energy. This paper discusses the range of approaches which can be employed to value changes in carbon emissions in policy appraisalsand presents some case studies and a survey of current practice in OECD countries.

It has become the accepted wisdom that meeting the global climate challenge will require zero net greenhouse gas (GHG) emissions by the end of this century. Read the full op-ed by Gabriela Ramos, OECD Special Advisor to the OECD Secretary-General.

More than 150 countries have submitted their post-2020 Intended Nationally Determined Contributions (INDCs) to the United Nations Framework Convention on Climate Change (UNFCCC). Such contributions are vital to the #COP21 climate change conference in Paris this December.

Advanced and emerging economies have made progress in addressing climate change, yet most are on a trajectory that would see them fall short of their mitigation goals. Governments need to significantly accelerate their efforts and strengthen their climate change policies.

How have CO2 and greenhouse gas (GHG) emissions changed since 1990? Three different visuals tell three very different stories (click on them to see full size). Which perspective offers the most clarity?

This report on climate change disclosure in G20 countries takes stock of mandatory climate change reporting schemes in G20 countries and identifies commonalities and divergences between the various schemes.

In order to help address climate finance-related information needs under the UNFCCC, this paper explores the extent to which currently-available secondary data make it possible to estimate private finance mobilised by developed countries for climate action in developing countries.

The IEA is pleased to announce the second event in its new distinguished speaker series, Big IdEAs, which brings global leaders and decision makers to the IEA to share their views on a range of global issues. On Friday 29 January starting at 11h30, Professor Sir David King, the UK Foreign Secretary’s Special Representative for Climate Change, will speak on "Towards decarbonising the global economy".

Despite a relatively good performance on several points compared to other countries, there is still scope for improving the effectiveness of Israel’s taxation policy from an environmental perspective.

Urgent research is needed to assess the possible risks to human health and ecosystems from the ever-increasing amounts of engineered nanomaterials going into household waste and ending up in the environment, according to a new OECD report.

This paper presents the first empirical analysis of the macroeconomic relationship between environmentally related taxes and inequality in income sources. The analysis also investigates whether this relationship differs between countries which have implemented environmental tax reforms (ETRs) and ones which have not.

Clearly a revolution in the global economy is needed for a heavy reduction of GHG emissions. You may have heard of Carbon Capture and Storage or CCS. This technology prevents CO2 from fossil fuel combustion from accumulating in the atmosphere.

This report provides a brief review of how national government policies and guidelines apply to or regulate the use of environmental labelling and information schemes (ELIS) in selected OECD countries. The report reviews definitions relevant to environmental claims and identifies four types of potentially false or misleading environmental claims.

This report explores potential effects of the recent rapid growth in Environmental Labelling Information Schemes (ELIS) around the world, with a focus on the implications of ELIS multiplication for environmental effectiveness and international trade.

A stern warning for climate change, and our health - Shipping brings us 90% of world trade and has increased in size by 400% in the last 45 years. Cargo ships, tankers and dry-bulk tankers are an essential element of a globalised world economy, but they are thirsty titans and they won’t settle for diet drinks. There are up to 100,000 working vessels on the ocean and some travel an incredible 2/3 of the distance to the moon in one year.

The Paris Agreement is a landmark in collective efforts on climate change and is the result of many years’ hard work. It must now be implemented.

Climate change is not just about a change in climate towards hotter, wetter, and drier conditions, but also about an increase in the variability of the climate, as well as in the number and severity of extreme events.

‌Environment Ministers from OECD and key partner countries gathered in Paris on 28-29 September 2016 to discuss the environmental challenges facing the world and how to promote effective and efficient policy responses, under the guidance of the Chair, Minister Nick Smith (New Zealand) and the Vice-Chairs, Minister Irena Majcen (Slovenia) and Vice-Minister Marcelo Mena Carrasco (Chile).

Korea has improved access to environmental services and become a world leader in climate change mitigation technology.

New Zealanders enjoy a high environmental quality of life and access to pristine wilderness. However, New Zealand’s growth model, based largely on exploiting natural resources, is starting to show its environmental limits with increasing greenhouse gas emissions and water pollution, according to a new OECD report.

Developing countries are disproportionately affected by the rising trend of losses from climate-related extreme events. This paper uses case studies of Colombia and Senegal to examine how countries are using financial protection as part of their approaches to managing climate risks; it also identifies emerging priorities for development co-operation providers in supporting financial protection against climate risks.

This report examines the implications of regional climate governance for international trade and conversely the implications of regional trade governance for climate change action. Regional approaches to climate change governance are discussed with a specific focus on the rise of “climate clubs” and their implications for international trade.

Climate change is a clear and undeniable challenge that requires a global response. The Paris Agreement represents the careful crafting of a collective effort of over 190 countries to meet this challenge.

This paper presents updated results for the cost of ambient air pollution in 41 countries: the 6 major emerging economies known as the BRIICS – Brazil, Russia, India, Indonesia, China and South Africa – and the 35 OECD member countries.

OECD Secretary-General Angel Gurría announced today at the One Planet Summit in Paris the launch of the “Paris Collaborative on Green Budgeting”, a strategic initiative to assess and drive the alignment of national budgetary processes with the Paris Agreement and other environmental goals.

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".

The wet and verdant expanse of the Mekong Delta’s rivers and farms is a veritable rice bowl for the world. Not only do the region’s paddies produce half of Viet Nam’s rice crop yearly, the country is the world’s third largest rice exporter, with 17% of world exports of paddy rice. Our analysis identifies Viet Nam as facing the world’s fourth highest water risks for rice production.

Action to prevent the risk of major flooding in Paris and the Ile de France region has improved in recent years – particularly after the Seine burst its banks in May and June 2016 – but urban and territorial planning needs to be better adapted, governance strengthened and long-term funding clarified, according to the OECD.

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 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.

This report focuses on the extent to which governments have complied with the environmental commitments made in the trade agreements to which they are a Party. The report takes a two track approach. First, a review of implementation and evaluation reports associated with environmental provisions in such agreements is performed. Second, a survey of government officials, trade negotiators and other experts is carried out.

The Paris Collaborative on Green Budgeting was launched by the OECD Secretary-General Angel Gurría at the One Planet Summit in Paris on 12 December 2017. It aims to design new, innovative tools to assess and drive improvements in the alignment of national expenditure and revenue processes with climate and other environmental goals.

Hungary has made progress in greening its economy and cutting emissions, but it needs to speed up efforts to replace fossil fuels with renewable energy sources, improve energy efficiency in buildings and promote sustainable transport, according to a new OECD Review.

The Czech economy is thriving, with robust employment, expanding exports and falling government debt. Efforts should now focus on boosting workforce skills and innovation to improve labour supply and productivity, further reduce poverty and inequality, and green the economy, according to two new OECD reports.

This paper aims to test whether the inclusion of environmental provisions in Regional Trade Agreements has contributed to the improvement of environmental quality among the Parties to these agreements through empirical modelling and analysis. Three indicators are considered as a proxy for environmental quality: concentrations of suspended particulate matter less than 2.5 microns, sulphur dioxide and nitrogen oxide.

On 25 September 2018 in New York, the OECD, UN Environment and the World Bank Group hosted a high-level panel discussion on their joint initiative “Financing Climate Futures: Rethinking Infrastructure”. The project is being undertaken with the support of the German Federal Ministry of the Environment, Nature Conservation and Nuclear Safety.

Three years on from the commitments made at COP21 in Paris, the overwhelming majority of governments have not taken the necessary action to contain growing risks to the climate. With emissions on the rise again, OECD governments need to get serious about shifting their economies to a low-carbon model and stop investing in carbon-intensive infrastructure.

This summer, we witnessed record-breaking heat and extreme weather events across the globe. To address the urgent climate challenge, and meet our broader development goals, trillions of dollars need to be invested in low-emissions and resilient infrastructure.
