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. Please contact Catherine Bremer (catherine.bremer@oecd.org, 0603 483456) for interview requests.

Over the past year, OECD Insights has published a series of blogs from contributors inside and outside the Organisation on the issues being debated over the next two weeks at COP21 in Paris. Here they are, in alphabetical order by title.

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.

The world looks to the Paris Conference of the Parties to deliver a new climate agreement that transforms our development pathway. Success at COP21 can drive and accelerate the transition to a cleaner, healthier and more secure future, locking-in sustainable economic growth and development.

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.

World leaders faced a fundamental dilemma: take strong action to address the risks associated with climate change, or see the ability to limit this threat slip from their grasp. Check out how the OECD contributed to get a successful outcome on 12 December at COP21 in Paris.

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.

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.

Outdoor air pollution is a major determinant of health worldwide. The objective of this paper is to inform the development of improved estimates of the social costs of human morbidity impacts resulting from outdoor air pollution in two components; namely to develop a core set of pollutant-health end-points to be covered when estimating the costs of morbidity, and to review current estimates of the cost of morbidity from air pollution.

The IEA is pleased to announce the second event in its new distinguished speaker series, Big IdEAs, which brings global leaders and decision makers to the IEA to share their views on a range of global issues. On Friday 29 January starting at 11h30, Professor Sir David King, the UK Foreign Secretary’s Special Representative for Climate Change, will speak on "Towards decarbonising the global economy".

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.

“If He holds back the waters, there is drought; if He lets them loose, they devastate the land”. To be fair, that was in the days before governments played “a key role in developing targeted policy responses to market failures that impede the mitigation and allocation of drought and flood risks”, as the OECD report on Mitigating Droughts and Floods in Agriculture puts it.

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 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.

Countries that implement stringent environmental policies do not lose export competitiveness when compared against countries with more moderate regulations, according to a new OECD study that examines trade in manufactured goods between advanced and emerging economies.

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.

Cloudy head on climate change? Join the webinar on Wednesday 30 March 2016 from 1-2 pm (Paris time) with Professor Per Espen Stoknes on What we think about... when we try not to think about... global warming!

The natural environment provides crucial inputs and services for economic development, but its role for productivity growth is insufficiently explored. Environmental scarcities can pose a drag on productivity growth and a risk for its sustainability.

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.

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.

The Paris Agreement is an unprecedented achievement in the fight against climate change. A record number of countries came together, first in the French capital for the COP21 conference in November-December 2015 and then formally to sign the agreement at the UN on 22 April 2016, to ensure that future generations enjoy a stable, healthy and habitable world.

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.

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.

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.

Advanced economies have reduced their consumption of raw materials and improved waste management, but more should be done to design and produce goods in a way that uses fewer natural resources and produces less waste, according to a new OECD report.

The theme of Biodiversity Day this year is “Mainstreaming biodiversity; sustaining people and their livelihoods”. According to World Bank figures, “natural capital accounts for an estimated 30% of total wealth in low income countries compared to only 2% in OECD countries”.

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.

The Paris Agreement is a landmark in collective efforts on climate change and is the result of many years’ hard work. It must now be implemented.

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.

Sound public policies grounded in evidence – and implemented effectively – will be crucial for the achievement of the 2030 Agenda for Sustainable Development. This document outlines four broad areas for future action for the OECD, highlighting what it could do more of – or do differently – to support the achievement of the Sustainable Development Goals. C/MIN(2016)6.

Outdoor air pollution could cause 6 to 9 million premature deaths a year by 2060 and cost 1% of global GDP – around USD 2.6 trillion annually – as a result of sick days, medical bills and reduced agricultural output, unless action is taken, according to a new OECD report.

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.

Chile has taken steps to address the rising environmental pressures from its rapid economic growth, strengthening its environmental institutions and introducing new instruments, including a carbon tax. It now needs to move ahead and thoroughly implement policy measures to stem the threat to its land, air and water, according to a new OECD report.

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.

Climate change is not just about a change in climate towards hotter, wetter, and drier conditions, but also about an increase in the variability of the climate, as well as in the number and severity of extreme events.

The OECD has welcomed the release by China and the US of peer reviews of their fossil fuel subsidies.

Anyone else feeling exhausted by all this drum humming about air pollution? Indeed it appears the fumes won’t be dissipating any time soon as we consider the extent to which tyre and brake rubbish exacerbate the problem.

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.
