Discover Key OECD initiatives

The OECD supports and helps drive higher levels of ambition and tangible outcomes – on mitigation, adaptation and resilience, and financing – that better align with the collective goals of the Paris Agreement.

The Inclusive Forum on Carbon Mitigation Approaches (IFCMA) is an initiative designed to help improve the global impact of emissions reduction efforts around the world through better data and information sharing, evidence-based mutual learning and inclusive multilateral dialogue. It brings together all relevant policy perspectives from a diverse range of countries from around the world, participating on an equal footing basis, to take stock of and consider the effectiveness of different carbon mitigation approaches.

The Climate Change Expert Group (CCXG) is a group of government delegates and experts from developed and developing countries. The aim of the group is to promote dialogue on and enhance understanding of politically important technical issues in the international climate change negotiations and for the implementation of the Paris Agreement.

The OECD’s Horizontal Project on Climate and Economic Resilience is using the multidisciplinary reach of the OECD to support governments in driving the swift transformational change needed to tackle climate change. The project will provide analysis and insights for governments looking at the whole climate picture: driving a rapid and resilient transition to net-zero while building resilience to physical climate impacts, all in the context of lingering effects of COVID-19 and the far-reaching effects of Russia’s unprovoked war of aggression in Ukraine.

The OECD International Programme for Action on Climate (IPAC) supports country progress towards net-zero greenhouse gas (GHG) emissions and a more resilient economy by 2050. Through regular monitoring, policy evaluation and feedback on results and best practices, IPAC helps countries strengthen and co-ordinate their climate action. It complements and supports the UNFCCC and the Paris Agreement monitoring frameworks.

Discover OECD publications

OECD publications aim to make available to a wider readership selected studies on environmental issues drawing on the work of the OECD on climate action.

This paper explores how Parties can prepare enhanced NDCs that take forward GST1 outcomes on mitigation and relevant provisions on NDCs, building on lessons learned from successive NDCs and available follow-up opportunities to support this process.

Building on a cross-country survey and country case studies carried out in Chile, Korea, the Slovak Republic and the United Kingdom, this report provides insights into current OECD country practices in measuring climate adaptation.

Aligning finance with climate policy goals is crucial for achieving net-zero greenhouse gas emissions and resilience to climate change, as called for by Article 2.1c of the Paris Agreement. Evidence-based policy making and investment decisions towards such alignment need to be informed by robust assessments. To support such efforts, this inaugural OECD Review on Aligning Finance with Climate Goals brings together best-available evidence on three core questions.

This paper puts forward key findings that can help to inform the final months of international discussions relating to the NCQG.

This year's edition presents a comprehensive evaluation of net-zero targets, major climate-related hazards, and the key trends in climate action. Directed towards policy makers and practitioners, the findings suggest that current 2030 commitments to reduce greenhouse gas emissions are not ambitious enough to meet the Paris Agreement temperature goals, and that without a significant expansion in national climate action, countries will not be able to meet the net-zero challenge.

The Climate Adaptation Investment Framework has been developed to help governments unlock increased investment in adaptation by strengthening their domestic policies. Building on the OECD's Policy Framework for Investment and Foreign Direct Investment Qualities Policy Toolkit, it provides non-prescriptive guidance covering critical policy areas for climate adaptation, as well as useful questions, examples of good practice and links to relevant resources.

Pricing Greenhouse Gas Emissions 2024: Gearing Up to Bring Emissions Down tracks how explicit carbon pricing instruments as well as specific taxes and subsidies on energy use have evolved between 2021 and 2023 across 79 countries, covering approximately 82% of global greenhouse gas (GHG) emissions. This report focuses on emissions trading systems, carbon taxes, fuel and electricity excise taxes, as well as subsidies that lower prices on emissions or energy products. The tax rates for this edition reflect rates applicable on 1 April 2023 while emissions trading schemes implemented throughout 2023 are also included.

Discover OECD data

OECD data and indicators on the environmental, economic, financial and social dimensions of climate change provide essential information for effective climate policies. Navigate the data, explore emissions by country and by sector, and countries’ energy mix, and learn more about country policies including carbon pricing, fossil fuel subsidies and investment in renewable energy.

The Environment at a Glance Indicators provide real-time interactive on-line access to the latest comparable OECD-country data on the environment from the OECD Core Set of Environmental Indicators – a tool to evaluate environmental performance in countries and to track the course towards sustainable development.

The Climate Action Dashboard by the OECD features key indicators to track progress towards climate objectives and provide a snapshot of country climate action. It is one of the four components of the International Programme for Action on Climate, set up to help countries pursue progress towards net-zero greenhouse gas emissions and a more resilient economy by 2050.

The OECD provides a platform to help governments evaluate their allocation of scarce budgetary resources to fossil fuels and their alignment with environmental and well-being goals. To do so, the OECD Inventory of Support Measures for Fossil Fuels documents and estimates government measures that encourage fossil-fuel production or consumption relative to renewable alternatives.

Despite the key financial role that regions and cities play in the carbon-neutral transition and the global response to climate change due, in large part, to their jurisdiction over crucial adaptation and mitigation-relevant policy areas (land-use planning, waste management, transport) there is a lot that we do not know about their financial role.

Climate Club highlights progress on decarbonising heavy industry in Leaders Event at COP29 in Baku.

The Climate Club, initiated in 2022 by the G7, was launched at COP28 by 35 countries and the European Union. It focuses on decarbonising industry in emerging and developing economies where much of the industrial growth will happen in the following years. To achieve near-zero emissions in industrial production, the Climate Club seeks to foster cooperation and collective action.

Delivered on 12 November 2024 in the context of the high-level Climate Club event at COP29.

Current emissions reduction targets are still falling short of the 1.5°C goal established by the Paris Agreement, reminding us of the urgent need for stronger action. The OECD's International Programme for Action on Climate (IPAC) provides key data and metrics to assess countries’ progress towards net-zero goals.

Watch

Climate change impacts are increasingly being felt and are projected to become more extreme. Yet, current levels of investment in climate adaptation are insufficient. The OECD developed a Climate Adaptation Investment Framework to help governments put in place the policies needed to increase public and private investment in climate change adaptation.
