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. 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.

This event held on 16-17 September 2014 at the IEA 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.

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 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.

This report is the third OECD review of Sweden’s environmental performance. It evaluates progress towards sustainable development and green growth, with a focus on Sweden's longstanding commitment to mitigating emissions of greenhouse gases and its management of marine ecosystem services and water.

Find out how the OECD participated in the 20th session of the Conference of the Parties to the United Nations Framework Convention on Climate Change (COP 20) which took place from 1-12 December in Lima, Peru.

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.

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.

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.

The international discussions under way in the course of this vital year–including July’s Finance for Development Meeting in Addis Ababa, the agreement of a new set of universal Sustainable Development Goals at the UN in September and the climate change summit in Paris at the end of 2015–represent a remarkable and unprecedented opportunity to establish what might be called a “Magna Carta for the earth” for our times.

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.

"We absolutely should and must demand a strong deal in Paris". Read the full blog by Chris Barrett, Executive Director, Finance and Economics, European Climate Foundation, and former Australian Ambassador to the OECD.

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.

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.

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.

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.

"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...

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.

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 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.

The UN Conference on Climate Change (COP21) in Paris 30 November-11 December is a once-in-a-generation opportunity to reach a new international agreement to combat climate change and accelerate our transition to a low-carbon economy. The “carbon entanglement” of our economies is keeping us on a collision course with nature.

Climate change mitigation requires globally, at national levels and locally, and across a range of policy areas. Priorities include widening the scope of carbon markets and investing more in innovative technologies. Efforts to cut emissions need to be stepped up, both in energy-related areas and in sectors like industry, agriculture and waste.

OECD urges efforts to better price carbon as new analysis finds that 90% of CO2-emissions are priced below EUR 30 per tonne, a low-end estimate of climate damage, and 60% are not priced at all. Effective Carbon Rates in the OECD and Selected Partner Economies calculates effective carbon rates (ECR) on CO2-emissions from energy use for 41 countries which together use 80% of global emissions.

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.

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.

Given the years of preparation – and for some OECD colleagues, a life’s work – my hope was for an enduring, ambitious text, helping us to avoid climate catastrophe. My expectation was far less grand, more closely aligned to the reality of getting 195 countries to adopt an agreement with legal force.

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.

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.

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.

This paper provides an in-depth review of experiences and insights from mainstreaming biodiversity and development in South Africa. More specifically, it describes how biodiversity considerations have been mainstreamed in five key sectors/areas, namely: land use planning, mining, water, infrastructure, and the agricultural sector.

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.
