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.

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.

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

When considering a by-product, can this material or waste be used in another industry or in another manufacturing process instead of putting it into the environment, moving “from waste to resources” as the OECD says?

Concerns around potential losses of competitiveness as a result of unilateral action on carbon pricing are often central for policy makers contemplating the introduction of such instruments. This paper is a review of literature on ex post empirical evaluations of the impacts of carbon prices on indicators of competitiveness as employed in the literature, including employment, output or exports, at different levels of aggregation.

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. ‌

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.

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.

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.

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.

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.

Today, more than 22% of global emissions are covered by a carbon price. Almost 40 countries and over 20 cities, states and provinces use carbon pricing mechanisms or are planning to implement them. The OECD recommends that countries make carbon pricing the cornerstone of climate policy. Price signals sent to consumers, producers and investors alike need to be consistent and facilitate the gradual phase-out of fossil fuel emissions.

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.

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.

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.

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.

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.

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.

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.

Brazil has made remarkable social and economic progress in the past two decades, but must now overcome important challenges if it is to put its economy on a stronger, fairer, greener growth trajectory, according to two new reports from the OECD.

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.

Participants to the Arrangement on Officially Supported Export Credits have agreed new rules on official support for coal-fired power plants, including restrictions on official export credits for the least efficient coal-fired power plants, the OECD announced today.

This project is unique in that it explores how national-level policies impact household behaviour. Topics include energy use, food consumption, personal transport choices, waste generation and recycling, and water consumption. Yet the project does not specifically discuss the term “ecological footprint,” and it retains a macro-policy focus, targeting governments interested in learning which policies to implement.

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.

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.

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.

Paris is a beautiful city but has an ugly problem with air pollution. Using 2 wheels to get to work, one becomes acutely aware of this insidious addiction to cars, and the “essence” of the problem, DIESEL.

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.

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.

Water is linked to many economic activities, and there are complex channels through which water affects economic growth. The purpose of this report is to provide background information useful for a quantitative global assessment of the impact of water scarcity on growth using a multi-region, recursive-dynamic, Computable General Equilibrium (CGE) model.

This paper reviews the latest climate projections for West Africa and considers alternative ways in which the knowledge generated from climate science can be understood in the context of preparing for an uncertain future that provides practical help for decision makers.

Current carbon prices are falling short of the levels needed to reduce greenhouse gas emissions driving climate change, but even moderate price increases could have a significant impact, according to new OECD research.

This Global Forum, held on 24-25 October 2016, aimed to shed light on the links between environment and economic growth, and the toolkits to quantify these links. It provided a platform to explore how a well-managed natural environment can contribute to economic growth and how an effective and efficient regulatory system can best be designed?

New evidence on the effect of energy prices on outward FDI can provide some reassurance in light of concerns about Pollution Havens.
