This paper refines indicators to measure innovation in environment-related technologies, drawing on recent methodological advances that allow a more accurate assessment of environment-related innovation in a broader range of countries. Three indicators are discussed: an indicator of technology development; an indicator of international collaboration in technology development and an indicator of technology diffusion.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

Korea has improved access to environmental services and become a world leader in climate change mitigation technology.

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.

This paper describes MOLES 1.0, an integrated land-use and transport model developed with Object-Oriented Programming principles in order to combine selected characteristics from Spatial Computable General Equilibrium and microsimulation models. MOLES 1.0 models the links between urban land use, mobility patterns, urban economic activities and their environmental impacts, in particular air pollution and emissions of greenhouse gases.

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.

This paper presents updated results for the cost of ambient air pollution in 41 countries: the 6 major emerging economies known as the BRIICS – Brazil, Russia, India, Indonesia, China and South Africa – and the 35 OECD member countries.

“National governments must take the lead and do so with a recognition that they are part of a global effort.” Speaking last week at the Munk School of Global Affairs in Toronto, OECD Secretary-General Angel Gurría urged countries not to retreat behind their national borders in dealing with climate change.

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.

This paper details a methodology for calculating the extent of terrestrial and marine protected areas recorded in the World Database on Protected Areas by country, type and IUCN management categories. The method allows the data on protected areas to be summarised in a harmonised and more detailed way than is currently available, without requiring any additional reporting by countries.

One focus of tomorrow’s One Planet Summit, organised by President Macron, is “to determine how those working in public and private finance can innovate to support and accelerate our common efforts to fight climate change.”

The wet and verdant expanse of the Mekong Delta’s rivers and farms is a veritable rice bowl for the world. Not only do the region’s paddies produce half of Viet Nam’s rice crop yearly, the country is the world’s third largest rice exporter, with 17% of world exports of paddy rice. Our analysis identifies Viet Nam as facing the world’s fourth highest water risks for rice production.

Action to prevent the risk of major flooding in Paris and the Ile de France region has improved in recent years – particularly after the Seine burst its banks in May and June 2016 – but urban and territorial planning needs to be better adapted, governance strengthened and long-term funding clarified, according to the OECD.

Taxes are effective at cutting harmful emissions from energy use, but governments could make better use of them. Greater reliance on energy taxation is needed to strengthen efforts to tackle the principal source of both greenhouse gas emissions and air pollution, according to a new OECD report.

This report focuses on the extent to which governments have complied with the environmental commitments made in the trade agreements to which they are a Party. The report takes a two track approach. First, a review of implementation and evaluation reports associated with environmental provisions in such agreements is performed. Second, a survey of government officials, trade negotiators and other experts is carried out.

This paper reviews the existing literature on modelling the macroeconomic consequences of the transition to a circular economy. It provides insights into the current state of the art on modelling policies to improve resource efficiency and the transition to a circular economy by examining 24 modelling-based assessments of a circular economy transition.

The Czech economy is thriving, with robust employment, expanding exports and falling government debt. Efforts should now focus on boosting workforce skills and innovation to improve labour supply and productivity, further reduce poverty and inequality, and green the economy, according to two new OECD reports.

26-31 August 2018 - The OECD will be participating at Stockholm World Water Week, the theme of which is "Water, ecosystems and human development”. The OECD is convening and speaking at a series of events throughout the week related to financing investment in water, water quality management and nature-based solutions.

This paper aims to test whether the inclusion of environmental provisions in Regional Trade Agreements has contributed to the improvement of environmental quality among the Parties to these agreements through empirical modelling and analysis. Three indicators are considered as a proxy for environmental quality: concentrations of suspended particulate matter less than 2.5 microns, sulphur dioxide and nitrogen oxide.

Three years on from the commitments made at COP21 in Paris, the overwhelming majority of governments have not taken the necessary action to contain growing risks to the climate. With emissions on the rise again, OECD governments need to get serious about shifting their economies to a low-carbon model and stop investing in carbon-intensive infrastructure.

Public support for metal extraction and processing has received little attention relative to that for the agriculture, energy, or fisheries sectors. This report addresses this knowledge gap by mapping out the most common forms of support provided for primary metals (produced from mineral ores) and secondary metals (produced from scrap).

The transition towards a resource efficient and circular economy has linkages with international trade through the emergence of global value chains as well as trade in second-hand goods, end-of-life products, secondary materials and waste. This paper highlights the interaction of international trade and the circular economy in order to map out potential issues to address and to guide further research areas to explore on this topic.
