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.

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.

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!”.

Angel Gurría, Secretary-General of the OECD congratulated the newly elected President of Indonesia, Joko Widodo, for taking a bold first step in his economic reform agenda by substantially cutting fuel subsidies.

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.

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.

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.

Our world and its problems should have been watched for long enough. Inequality, debt, financial instability, corruption, conflict, ecosystem damage, waste and poverty have been seen through history.

The OECD’s latest Environmental Performance Review of Spain finds the country has decreased the energy and carbon intensity of its economy, reduced industrial pollution and cut per-capita waste generation since 2000.

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.

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.

United Nations Secretary-General Ban Ki-moon today called on OECD governments to ensure that a series of major summits this year result in a new era of sustainable development.

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 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.

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.

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.

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.

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.

An early leader in environmental policy, the Netherlands has decoupled greenhouse gas emissions from economic growth and virtually eliminated landfilling over the past decade. Yet a very fossil fuel-intensive energy mix and looming pressures from traffic congestion and intensive farming are creating new challenges, according to a new OECD report.

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.

Following is a list of OECD activities and events during the COP21 UN Conference on Climate Change. You can visit the OECD Pavilion in Hall 3 (Blue Zone) at any time to attend events (complete list of OECD events at COP21) and browse OECD reports & dataviz on climate change and the environment.

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.

This is a watershed day for the world and especially heartening for the OECD as one of the first international bodies to call for zero net emissions in the second half of the century, for a price on carbon and for greater efforts to channel finance into the low carbon economy.

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.

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.

Clearly a revolution in the global economy is needed for a heavy reduction of GHG emissions. You may have heard of Carbon Capture and Storage or CCS. This technology prevents CO2 from fossil fuel combustion from accumulating in the atmosphere.

The initials ‘CCS’ usually stand for Carbon Capture and Storage. However, I was with the team in Paris during COP21 promoting the Cap Global Carbon proposal; the mechanism embodied in Cap Global Carbon is Cap & Share, and it occurred to us that the name ‘Carbon Cap & Share’ has the same initials, CCS. Are these two types of CCS complementary or antagonistic? Are they friends or enemies?

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.

China was among the near-200 countries to adopt the Paris Climate Change Agreement (Paris Agreement) at an historic UN conference in Paris, France on 12 December 2015. As an emerging economy and one of the world’s major emitters of greenhouse gases, how China implements the Paris Agreement will be important. We asked Dr Xuedu Lu of the Asian Development Bank for his views.

This brief is a contribution to the 22nd Conference of the Parties to the United Nations Framework Convention on Climate Change (COP22) and a submission of recommendations for the renewal of the Lima Work Programme on Gender. It provides an overview of how well members of the OECD Development Assistance Committee (DAC) are integrating gender equality into their bilateral aid to climate change.

This study was one of the first attempts to evaluate and quantify the benefits of transboundary co-operation between Georgia and Azerbaijan. A specific framework for inventorying these benefits, taking into account all the different dimensions of transboundary water management, was built and applied to the major transboundary water bodies.

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.

Integrating measures to tackle climate change into regular economic policy will have a positive impact on economic growth over the medium and long term, according to a new OECD report prepared in the context of the German Presidency of the G20.

This report examines the implications of regional climate governance for international trade and conversely the implications of regional trade governance for climate change action. Regional approaches to climate change governance are discussed with a specific focus on the rise of “climate clubs” and their implications for international trade.

Climate change is a clear and undeniable challenge that requires a global response. The Paris Agreement represents the careful crafting of a collective effort of over 190 countries to meet this challenge.

Countries need to look beyond narrow national policy agendas to curb global emissions and reduce climate risks, OECD Secretary-General Angel Gurría said today. Governments should seize the flexibility built into the 2015 Paris Agreement to increase and accelerate their emissions-cutting ambitions.

Air pollution in Delhi has been so bad this November that the Indian Medical Association declared a public health emergency. According to the latest Global Burden of Disease study published in The Lancet, outdoor air pollution caused more than a million premature deaths in India in 2016, whose cost, according to OECD estimates, amounts to more than USD 800 billion. Read the full blog.

Infrastructure resilience requires a coordinated policy response to ensure that infrastructure owners and developers have the incentive and capacity to integrate resilience. The framework is aimed at policy makers in OECD countries, but the underlying messages can be applied to other country contexts.

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.

OECD Secretary-General Angel Gurría announced today at the One Planet Summit in Paris the launch of the “Paris Collaborative on Green Budgeting”, a strategic initiative to assess and drive the alignment of national budgetary processes with the Paris Agreement and other environmental goals.
