The OECD participated in this annual event held in Stockholm (1-5 September 2013) where two major reports "Water Security for Better Lives" and "Water and Climate Change Adaptation: Policies to Navigate Uncharted Waters" were launched by the OECD's Secretary-General, Angel Gurría.

The meeting took place on 17-18 September 2013 in Tbilisi, Georgia and marked the 20th anniversary of the OECD environment-related co-operation with countries of Eastern Europe, Caucasus and Central Asia.

We must aim for their complete elimination by the second half of the century and need to come to grips with the risk of climate change. While many countries have announced ambitious targets to reduce fossil fuel emissions by 2020, and even mid-century, further efforts are needed.

Governments need to put together the optimal policy mix to eliminate emissions from fossil fuels in the second half of the century. Cherry-picking a few easy measures will not do the trick. There has to be progress on every front, notably with respect to carbon pricing, and that is what peer review and learning from best practice should help achieve, said OECD Secretary-General.

The Government of Israel and the OECD co-organised an international conference on "Joining Forces to Develop Smart, Cost-Effective Urban Water Utilities: Policy, Economics, Environment, Regulation and Technologies" on 23 October 2013, in Tel Aviv.

Carbon taxes and emission trading systems are the most cost-effective means of reducing CO2 emissions, and should be at the centre of government efforts to tackle climate change,according to a new OECD study.

Air pollution is costing advanced economies plus China and India an estimated USD 3.5 trillion a year in premature deaths and ill health and the costs will rise without government action to limit vehicle emissions, a new OECD report says.

Today’s post, marking World Environment Day, is from OECD Secretary-General Angel Gurría. Air pollution has become the biggest environmental cause of premature death, overtaking poor sanitation and a lack of clean drinking water.

In its 2012 edition of the World Energy Outlook, the International Energy Agency (IEA) produced an Efficient World Scenario to assess how implementing only economically viable energy efficiency measures would affect energy markets, investment and greenhouse emissions (GHG). Using the OECD ENV-Linkages macro-economic model, this report simulates the economic and environmental impacts which the IEA Efficient World Scenario implies.

This workshop focused on putting priorities into practice in OECD countries. Country-specific prioritisation, sectoral approaches, mainstreaming tools including questions on public sector finance and research needs were all topics covered during the two days of the workshop.

Climate change and biodiversity loss have increasingly become the subject of international policy deliberations. It is widely recognised that strong and effective international co-operation is required to address these issues. Co-operation in science and technology between developed and developing countries is considered to be of particular importance.

Education plays a crucial role in raising awareness of environmental challenges and shaping the attitudes and behaviours that can make a difference. A recently released Trends Shaping Education Spotlight looks at the role of education in both preparing and providing our citizens with the skills needed for a sustainable and productive future.

Iceland must balance growth in power and tourism industries with nature conservation, OECD says Iceland has one of the world’s most pristine natural environments and its glaciers, volcanoes and hot underground springs bring major economic benefits via renewable energy and tourism.

Reversing the damage is within our grasp, but it will hinge on a strong international climate agreement and policies that make polluters pay. Op Ed by Angel Gurría, OECD Secretary-General and Nick Stern, Chair of the Grantham Institute for Climate Change and the Environment at the London School of Economics, The Guardian.

Saving the Earth’s climate is sometimes compared to saving the world’s financial system following the crisis in 2007. But it’s not. The taxpayer saved the financial system by bailing it out a cost of trillions of dollars over a very short period, but there is no bailout option for the climate.

The UN Climate Summit took place on 23 September 2014 at the United Nations Headquarters in New York. The OECD's Secretary-General, Angel Gurría, chaired the session on "The Economic Case for Climate Action," where global leaders discussed The New Climate Economy Report: Better Growth, Better Climate, by the Global Commission on the Economy and Climate.

As the Millennium Development Goals (MDGs) approach their expiry date, we must focus our efforts on ensuring a brighter, more inclusive and sustainable future for all. We face a plethora of common issues: growing inequalities; changing consumption patterns and population dynamics; increasing natural resource scarcity; and ongoing illicit financial flows.

Despite large and growing investments in knowledge and innovation, productivity growth in many countries has slowed in recent years. At the same time, the urgent need for more rapid innovation (including its uptake and diffusion) in several key areas, such as in environment. This joint OECD-NBER workshop on 25-26 September 2014 will bring together academic experts to consider these challenges.

When you think of biodiversity conservation, you probably think of the classic images: the polar bear, the lion, the elephant, the giraffe. The ecological community likes to call them charismatic megafauna, with only a hint of satire.

The G20 needs to go structural, social, and green! With fiscal and monetary policy room nearly exhausted, structural reforms are the best choices, sometimes the only choice. The OECD battle cry in this regard has been unchanged since 2008: “go structural!”.

This meeting addressed green growth policies for small and medium-sized enterprises, water governance in line with green economy requirements, and reporting on the Task Force programme implementation and plans for 2015.

Climate policy and competitiveness issues have created a new need for international co-ordination, beyond the scope of our current frameworks. There is no need to trade economic growth for environmental stringency. Environmentally stringent policies are an incentive for greater efficiencies which leading edge companies can easily achieve.

Please join me in an ode to the giant tortoise, recently confirmed to be back from near extinction on the Galapagos Espanola Island after conservation work that began forty years ago. Whoever thought this waddly wild wonk would be a model for humans to improve environment through adept household behaviour?

This study uses a unique dataset of investment flows to analyse the role of two categories of public interventions (finance and policies) in mobilising flows of private climate finance worldwide and in the more specific context of flows to and in developing countries. The objectives are threefold. Find out more.

The polar bear, floating mournfully away on an ice floe as his habitat melts around him, is perhaps one of the most well-travelled symbols of the impacts of climate change.

Business brief. Overcoming the challenges of an arid climate and scarce natural water reserves has always been a vital necessity for the growth of Israel’s population and economy since the founding of the state. This has led to continuous improvements in Israel’s water sector, through innovations in technologies, practices and long-term plans.

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.

Water resources allocation determines who is able to use water resources, how, when and where. Capturing information from 27 OECD countries and key partner economies, the report presents key findings from the OECD Survey of Water Resources Allocation and case studies of successful allocation reform.

Latest Environment Working Papers on greening household behaviour: overview of results from econometric analysis and policy implications; energy; food; transport; waste; and water.

This series is designed to make available to a wider readership selected studies on environmental issues prepared for use within the OECD. Two recent working papers: sustainable Consumption Dilemmas and Tender Instruments: Programme Participation and Impact in Australian Conservation Tenders, Grants and Volunteer Organisations.

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.

Developing countries are increasingly moving towards more strategic national policies and plans, the effectiveness of which will depend upon proper assessment of a given country’s vulnerability to climate change. This report draws upon emerging monitoring and evaluation practices across developed and developing countries to identify four tools that countries can draw upon in their own assessment frameworks.

Is it possible for 9 billion people to live on this planet and enjoy a good standard of living? And on such a planet, is it possible for economies to grow, businesses to profit, and communities to prosper without undermining the natural systems that support all life? And without destroying some of the planet’s last great wildernesses?

In January of this year I visited the Mexican state of Tabasco– a state crossed by rivers and facing the Gulf of Mexico. The state’s population has doubled over the past 30 years and its economy relies heavily on oil and natural gas resources. It has its challenges as well: unemployment, poverty and a lack of resources.

For many years one of the predominant conventional wisdoms in both business and policymaking circles was that cutting greenhouse gas (GHG) emissions necessitates a sacrifice in economic growth.

For the past decade or so, there has been a lot of debate in policy circles on how to get governments and the private sector to work together more collaboratively in order to catalyse the transition to green growth. The good news is that in that time many factors have come together to make this more of a reality.

Challenging free trade orthodoxy is a heavy lift in our political culture; anything that has been in place for that long takes on an air of inevitability. But, critical as these shifts are, they are not enough to lower emissions in time. To do that, we will need to confront a logic even more entrenched than free trade–the logic of indiscriminate economic growth.

This paper refines indicators to measure innovation in environment-related technologies, drawing on recent methodological advances that allow a more accurate assessment of environment-related innovation in a broader range of countries. Three indicators are discussed: an indicator of technology development; an indicator of international collaboration in technology development and an indicator of technology diffusion.

Governments should rethink the role of coal in energy supply as the scale of new investments being made in unabated coal-fired electricity generation poses the most urgent threat to our climate, OECD Secretary-General Angel Gurría said today.

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.

The recent droughts in Brazil’s Rio de Janeiro and São Paulo states have exposed the need to shift from crisis management to effective risk governance of the country’s water resources, according to a new OECD report.

The current Volkswagen diesel emissions scandal highlights the difficult reality of making the transition to a low-carbon economy. It also highlights the growing need for governments to make smart policies, based on actual costs.

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?

To increase transparency and improve understanding of different countries’ situations, the OECD has developed an interactive map that brings to life key climate change mitigation statistics and policy settings. The webinar on Monday 16 November 2015, 15h00-16h30 (Paris time) consisted of a summary of the main messages of the report "Climate Change Mitigation: Policies and Progress" and a demonstration of the interactive tool.

Tackling climate change may be costly, but not tackling it will cost even more. And the longer we wait to act, the more our environment, our health and our economies will be damaged. Find out more about the likely impacts of rising GHG concentrations on global temperature, and how that will affect all of us.

Countries everywhere have committed to fighting climate change but many are still subsidising fossil fuels, investing little in green technologies, failing to put a realistic price on carbon, and allowing transport emissions to grow. Much more can and should be done.
