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.

With headlines of record‑breaking water-related disasters around the world, this blog, written by Kathleen Dominique, OECD Environment Economist, discusses the water impacts of climate change. This post is part of Wikiprogress' series on "water" and the "environment".

This event held on 18-19 March 2014 at the OECD is part of a series of seminars, organised by the OECD and the IEA, which aims to promote dialogue and enhance understanding between a wide range of experts on technical issues in the international climate change negotiations. The agenda, presentations and list of participants are now available.

The latest Climate Change Report from the IPCC argues that human interference with the climate system is occurring, and climate change poses risks for human and natural systems. The report identifies eight major risks with high confidence, and says that each of these risks contributes to one of more of the five “reasons for concern”.

A new OECD report describes what Ethiopia and Columbia are doing to sustain development in a changing climate.

The OECD’s 34 member countries today affirmed their common resolve to work towards a deal on combating climate change at the COP21 talks in Paris in 2015. OECD accession countries Colombia and Latvia joined the statement issued at the Organisation’s annual Ministerial Council Meeting, attended by finance, economy, trade and other ministers.

Twenty years ago climate change was viewed as just an environmental issue. Today it is squarely an economic issue. Climate change poses significant risks to our economic systems that could result in very large damages. To mitigate these risks we need to radically transform our economies and societies to stop global warming.

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 document provides a detailed technical description of the ENV-Linkages model. The OECD ENV-Linkages Computable General Equilibrium (CGE) model is an economic model that describes how economic activities are inter-linked across several macroeconomic sectors and regions. It links economic activity to environmental pressure, specifically to emissions of greenhouse gases (GHGs).

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.

Extended Producer Responsibility (EPR) is increasingly recognised worldwide as an efficient waste management policy to help improve recycling and reduce landfilling of products and materials. This Forum took place on 17-19 June 2014, in Tokyo, Japan, to identify key challenges and opportunities for further developing EPR policies.

In many areas today, there is no such thing as a “natural” landscape. Thousands of years of farming have selected and encouraged some species, marginalised or eliminated others. The land itself has been altered by ploughing, enclosure, herding and other human interventions. We may feel that we have tamed Nature. Reports like this new one from the OECD remind us of our ignorance and warn us about our arrogance.

This Global Forum plays an important role as the tool for on-going dialogue on responsible business conduct. I am pleased to announce that today, Ministers from over 20 countries are coming together to discuss how to integrate responsibility considerations throughout government policies. Their work will contribute to protect internationally recognised fundamental rights and to ensure good governance, fair regulations, and transparency.

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.

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.

Reversing the damage is within our grasp, but it will hinge on a strong international climate agreement and policies that make polluters pay.

Angel Gurría and Michael R. Bloomberg reaffirmed today their commitment to support international cities’ efforts to lead in the global fight against climate change — and called for national support to make this happen.

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 OECD Environment Directorate has produced two videos to explain key climate issues as the UN Climate Summit opens today at UN headquarters in New York.

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 environmental pressures continue to rise, governments throughout the OECD area have not been sitting back. If anything, the stringency of their policy measures has been increasing on the whole, not least to combat pollution and climate change. And as the evidence shows, stringent environmental policies can be introduced without hurting overall productivity.

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.

In today’s hard times, policy-makers can find it difficult to sell their environmental policies. To many, these policies represent a burden on the economy.

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.

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.

It’s time for governments to ramp up the development of alternative energies and to nail a price onto every tonne of CO2 emitted. With COP21 taking place in Paris in November, sending the right message on climate change means gradually increasing the cost of CO2 emissions, and creating a strong economic incentive to reduce the carbon entanglement and to move towards a zero-carbon world.

If you’ve just visited the room with no windows and enjoyed the effortless push of the “deposit disposal button” followed by a stream of fresh, clean tap water to wash your hands, you could well be in an OECD city

Climate change and, more generally, environmental damage have quantifiable economic and health costs, which weigh on long-term growth and well-being. If left unchecked, climate change is projected to decrease global GDP by 0.7 to 2.5 % by 2060. At the same time, the costs to society of air pollution already appear substantial–equivalent to some 4% of GDP across OECD countries and even higher in some rapidly developing economies.

The OECD Secretary-General, Mr. Angel Gurría, chaired several high-level panels; the OECD actively participated through a series of events, the launch of four new reports and by taking part in a number of workshops and seminars throughout the forum. ‌

A transition to a low carbon economy is achievable, but will require a concerted, more consistent effort across a range of policy areas, from tradeable permits to stringent norms.

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 his remarks to the Business & Climate Summit, the Secretary-General said that business lies at the heart of what we need to achieve on climate action. If Governments produce clear, credible and coherent national policies and clear messages and signals, the full transformative power of business, markets and human ingenuity will be unleashed.

Over the coming months, the world will be preparing for what is heralded as an historic meeting for climate change negotiations. If the right decisions are taken–with the aim of making a sustainable energy future a reality–we will be able to reap enormous, multiple benefits deriving not only from decarbonisation, but also from reduced air pollution, better energy access, energy security and economic prosperity.

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.

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.

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.

This joint OECD/France conference to be held in Paris on 16 September 2015 will aim to lay the foundation for the international effort which is needed on public policy options and economic incentives to support food security, the fight against climate change and adaptation to climate change while integrating soil issues in that effort.

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.

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).

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.

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.

Average global temperature could rise by 3-6 degrees Celsius by 2100 if we don’t act. To keep the rise to 2 degrees Celsius, we need to have net zero emissions by the end of the century. Emissions would need to peak by 2030 to give us a fighting chance of achieving this.

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.

Tackling climate change will require action in three key areas. First, we must strengthen carbon pricing and remove fossil fuel subsidies. Second, we must remove barriers to green investment. And third, we must align policies across the economy to leave fossil fuels behind and improve transparency on climate finance.
