This report presents the OECD methodological guidelines for compiling Environmentally Related Tax Revenue accounts. The guidelines are in line with the System of Environmental Economic Accounting and ensure consistency with national and international data sources and manuals. The OECD guidelines are based on those of Eurostat with refinements and additional memo items. First, revenue from greenhouse gas taxes is split into two sub-categories: an energy-related part (recorded as an energy tax) and a non-energy-related part (recorded as a pollution tax). Second, four 'memo items' are introduced to enhance the relevance of the accounts for policy work: (i) certain land taxes, (ii) taxes on oil and natural gas extraction, (iii) taxes on the resource rent and (iv) elevated VAT levied on environmentally related tax bases. The practical application of these guidelines was successfully pilot-tested in 2018-19, and the guidelines were implemented in the 2019 and 2021 rounds of data collection from OECD member and partner countries. The results show that it is feasible to compile the accounts, including the refinements and the additions outlined in this document, across OECD and beyond.

Endocrine disrupting chemicals (EDCs) are contaminants of emerging environmental and health concern that have been detected in freshwater, wastewater and drinking water. They interfere with the endocrine system in humans and wildlife, and produce adverse effects such as developmental, reproductive, neurological and immune effects. Their presence in water raises concerns for the integrity of ecosystems and biodiversity. Addressing the challenges of EDCs in water is particularly complex due to their ability to trigger adverse effects at very low concentrations, their potency in mixtures with other chemicals, and the vast range of sources and entryways of this group of chemicals into the environment. This report presents new water quality monitoring methods, such as bioassays and non-targeted analysis, that are well equipped to capture the impacts of EDCs in water. These new methods supplement the traditional substance-by-substance chemical analysis of water quality. The report also outlines policy instruments to manage the chemicals’ lifecycle from source to end-of-pipe. It proposes tools and regulations that respond to the negative effects of endocrine disruption, even if the culprit chemical is still unknown. The analysis draws on case studies from OECD countries to provide practical examples and concrete policy actions.

In recent years, international development co-operation has undergone a transition from a conventional donor-recipient model to a partnership-centred approach, including with regions and cities. Friuli Venezia Giulia, a small region in north-eastern Italy with extensive policy autonomy, has been active in international co-operation and is seeking to get more out of its actions both for the region and with its co-operation partners around the world. This paper evaluates its strategy on international partnership and co-operation and proposes recommendations, including more targeted initiatives that leverage the expertise of the region for greater impact in partner countries and for local benefits.

A megadiverse county, Costa Rica is known globally for its success in reversing deforestation and pursuing a growth model based on the sustainable use of its environmental resources. However, energy use and related greenhouse gas emissions increased in the last decade. Private cars are a major and growing source of emissions affecting climate and air quality. Waste disposal still relies on landfills, and much wastewater is untreated. Costa Rica’s extensive protected area network and pioneering programme of payments for ecosystem services have helped reduce biodiversity loss and extend forests’ carbon sequestration capacity. However, more should be done to tackle pressures on biodiversity from development of infrastructure and settlements, tourism, farming and fishing. The sheer scale of investment needed to achieve the Sustainable Development Goals calls for improving the efficiency of public spending, mobilising private finance, strictly enforcing regulations and providing adequate incentives. This is the first OECD Environmental Performance Review of Costa Rica. It evaluates the country’s progress towards sustainable development, with a special chapter focusing on biodiversity, and provides 52 recommendations.

While many countries of Latin America and the Caribbean (LAC) have committed to achieving climate neutrality and building resilience, translating these commitments into actions is imperative. This requires, for instance, better management of increasing risks from climate change and climate variability, as well as reducing greenhouse gas (GHG) emissions through promoting innovation and green investments. Achieving these goals will require comprehensive long-term strategic and financial planning, a more integrated and inclusive approach, which better aligns adaptation and mitigation policies and measures across different sectors, albeit at a differentiated level. This report identifies LAC countries’ main climate change policy priorities, which were discussed through a series of Regional Policy Dialogues and Expert Workshops and complements these with findings of recent analyses by the OECD and other international partners. It explores issues related to their implementation on climate adaptation, mitigation, and cross-cutting policy areas. The report covers various economic sectors, ranging from energy, transport, agriculture and tourism, as well as environment-related policies on infrastructure, water, biodiversity and ecosystems. The report also explores cross-cutting topics, such as climate governance and finance, environmental information, technology transfer, circular economy, oceans, gender equality and education. To overcome challenges and grasp the opportunities associated with a transition towards climate resilience and neutrality, the report proposes an Action Plan, with 40 key policy recommendations.

Carbon lock-in occurs when high-emission infrastructure or assets continue to be used, despite the possibility of substituting them with low-emission alternatives, thereby delaying or preventing the transition to near-zero or zero-emission alternatives. Transition finance, which focuses on the dynamic transformation and decarbonisation of hard-to-abate sectors, frequently faces the issue of carbon lock-in, particularly in considerations of investment feasibility and eligibility. Despite most transition finance approaches incorporating lock-in avoidance as a core principle, existing transition instruments and approaches put in place varying or limited mechanisms to prevent lock-in. Building on the OECD Guidance on Transition Finance, this report takes stock of how carbon lock-in risk is addressed in existing transition finance approaches (such as taxonomies, roadmaps, or guidance), financial instruments, and relevant public and private investment frameworks and methodologies. The report provides good practices on the integration of credible mechanisms to prevent carbon lock-in, address greenwashing risks and build confidence in the market. It can inform both public and private actors in the development of transition finance approaches, standards for green, transition and sustainability-linked debt, frameworks for corporate transition plans, or broader climate-related disclosure frameworks.

Policies aimed at reducing the environmental impact of human activities have important consequences for labour markets, jobs, and skills. As employment is shifting towards more sustainable activities, workers are increasingly expected to have skills that support the transition to a greener economy. Assessing and anticipating emerging skill needs is crucial to avoid bottlenecks and sustain the green transition. This report sheds light on existing methods to measure changes in skill demand and supply related to the green transition through an in-depth review of practices in five OECD countries (Australia, Austria, France, Norway and Sweden). It also identifies best practice on how to feed information on changing skill needs into policies, notably in the areas of employment, career guidance, education and adult learning.

This Policy Guidance is a product of the Development Assistance Committee’s multi-year programme of work on Illicit Financial Flows (IFFs) in oil commodity trading. It proposes a set of relevant, feasible actions for providers of official development assistance (ODA) to respond to IFFs in oil commodity trading. The aim is to enhance the mobilisation of domestic resources for the benefit of populations living in oil-producing developing countries, and enable integrity in their energy transition, particularly in carbon trade.
