Mexico’s river basins are under severe water stress. The quality of rivers, lakes and aquifers is declining and floods, droughts, and hurricanes are more frequent. These are some of the alerts signaled in OECD’s Making Water Reform Happen in Mexico.

Mexico is faced with difficult trade-offs as it pursues its economic, social and environmental goals. Like other emerging economies Mexico is balancing the need to protect its natural resources with the need to address high levels of income inequality and poverty.

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.

The GGKP’s second annual conference will be held at the OECD Headquarters in Paris on 4-5 April 2013. The discussion will be framed around two headline themes: Greening global value chains and Measurement and reporting for green growth.

The rise in international investment and trade in goods and services related to renewable energy has been rapid but not always smooth. This paper surveys, through the lenses of market-pull and technology-push policies, the numerous domestic incentives used by governments to promote renewable energy, focusing on those that might have implications for trade.

This paper proposes a new measure of stringency to measure the consequences of environmental regulations on investment, labour demand, and patterns of international trade that would be based on emissions data and which could be constructed separately for different pollutants.

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.

The OECD organised a number of events focused on key aspects of the negotiations: side events on tracking private climate finance, establishing and understanding post-2020 mitigation commitments, and credible policies to achieve climate targets and mobilise private finance. The OECD also convened a High Level Breakfast addressing the issues around long-term investment and green infrastructure.

The Netherlands is a global pioneer in water management with a long history of containing flood risks and reclaiming land from the sea. Yet it will need to adapt its water governance policies to meet the looming challenges of shifting demographics, regional development and climate change, according to an OECD report.

This paper presents a framework to include feedbacks from climate impacts on the economy in integrated assessment models. The proposed framework uses a production function approach, which links climate impacts to key variables and parameters used in the specification of economic activity. The paper pays particular attention to the challenges of distinguishing between damages and the costs of adapting to climate change.

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.

The paper reviews a number of commercial and public data sources to examine their potential for increasing coverage and understanding of the volume and characteristics of private climate finance beyond renewable energy projects. Such information is needed to assess progress towards the global transition to low-carbon, climate-resilient economies.

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.

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.

Water security is one of the greatest challenges we face today, yet the situation has never looked more perilous. By 2050 the OECD Environmental Outlook projects that nearly 4 billion people will live in river basins under severe water stress, and global nitrogen effluents from wastewater are projected to grow by 180%. Whilst, over the same period, global demand for water is expected to grow by 55%.

The world will need more and better targeted financing to meet the challenges of global development post-2015. This means taking important decisions not only on what qualifies as official development assistance (ODA), but also on how those flows can be most strategically used.

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.

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.

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.

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.

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.

Public and private finance mobilised by developed countries for climate action in developing countries reached USD 62 billion in 2014, up from USD 52 billion in 2013 and making an average of USD 57 billion annually over the 2013-14 period, according to a new OECD study in collaboration with Climate Policy Initiative (CPI).

"Back to the Future" festivities marking 21 October 2015 as the date Marty and Doc travel to the future in the famous film with Michael J. Fox. If only we had a similar time machine allowing us to travel to 2045 to see what the climate has in store to better decide what policies to adopt today. Alas, no time machine has been invented yet but, in the absence of such a cool device, we can rely on climate and economic models...

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.

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.

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.

The consequences of degradation of environmental quality as well as the consequences of environmental policies are typically unevenly distributed. In general, poorer countries and lower income households are more severely affected by environmental degradation and at the same time have less capacity to adapt.

A dirty, rundown environment has quantifiable costs for the economy and the well-being of societies. For example, the welfare costs of air pollution from road transport alone are estimated to amount to around 1.7 trillion USD in OECD countries, 1.4 trillion USD in China and 0.5 trillion in India.

This report provides a review of recent firm-level and plant-level surveys containing questions on environmental policies, innovation practices or performance which are relevant for environmental policy analysis and assessment. We specifically focus on the core element that relates environmental policies to environmental and economic performance, namely the adoption of innovative practices and environmental innovations by firms.

Peru is a multicultural, megadiverse country, with abundant ecosystem and natural resources, and an ancient tradition in the sustainable management of its resources. Growing pressures from extractive industries, unplanned urbanisation and deforestation are threatening its natural heritage and the population's well-being.

The OECD will convene its 6th Workshop on Regional trade agreements and the environment on 10 June 2016, at the OECD Headquarters. The focus of the workshop will be on chapters of regional trade agreement (RTAs) that are concerned mainly with issues other than the environment, such as market access, investment, or government procurement, TBT, regulatory coherence or dispute settlement.

France has improved its environmental performance over the last decade, lowering greenhouse gas emissions, reducing some air pollutants and cutting its use of fresh water. Further effort will be needed, however, to reduce pollution by nitrates and pesticides and meet ambitious renewable energy targets, according to a new OECD report.

This paper surveys a broad range of studies and highlights the main findings of the empirical literature regarding business finance and productivity.

Estonia needs to move faster to reduce its dependence on oil shale so it can advance towards a greener economy and reduce air pollution and waste generation, 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 provides an analysis of how climate change damages may affect international trade in the coming decades and how international trade can help limit the costs of climate change. It analyses the impacts of climate change on trade considering both direct effects on infrastructure and transport routes and the indirect economic impacts resulting from changes in endowments and production.

Ending poverty and combating climate change: two years after the adoption of the UN Sustainable Development Goals and the Paris Climate Agreement, these inter-related challenges remain as daunting as ever, not least in developing countries.

Our response to the climate challenge will define our collective future for generations to come. We must act. We must act swiftly, collectively, and decisively.
