This paper is part of a subset of working papers within the Environment Working Paper series, presenting research on the enabling environment for investment in water security. The subset includes country and regional projects aimed at pilot testing the Scorecard, designed to assess the enabling environment for investment in water security. The paper 'Assessing the Enabling Conditions for Investment in Water Security: Scorecard Pilot Test in Asian Countries' delineates the findings from the initial phase. This paper marks the commencement of the second round of pilot tests in the EU’s Eastern Partnership Countries. It presents the results obtained from assessing the enabling environment for investment in water security in Armenia, using the Scorecard. It also presents policy recommendations based on the priority investment barriers identified during stakeholder consultations in the country, involving representatives from various Ministries engaged in water security and international donors. The assessment and recommendations cover the public investment framework and its impact on water-related sectors, the water investment framework, project bankability and sustainability, as well as the contribution of other economic sectors to water security.

There is mounting evidence that, depending on social and economic circumstances, some communities and groups may face disproportionate exposure to environmental hazards, bear an inequitable share of the costs associated with environmental policies or face more barriers to participating in environmental decision-making. As countries increase their efforts to tackle environmental degradation, pollution and climate change, the concept of environmental justice can shed light on how to ensure fairness in the processes and outcomes of environmental policymaking. This report examines the plurality of the concept of environmental justice, its underlying conceptual pillars and how it has emerged in different contexts around the world. The report also provides the first policy stocktake of how governments across the OECD and beyond are seeking to redress environmental justice concerns, building upon insights from 26 responses to the OECD Environmental Justice Survey as well as complementary desk analysis across a broader set of countries.

The Paris Agreement is underpinned by Nationally Determined Contributions (NDCs) in which Parties set out how they plan to support the Agreement’s long-term temperature goal. Parties are to submit their next NDCs by early 2025, informed by the first global stocktake (GST1). The GST1 sets out key signals and a series of mitigation focused calls in line with 1.5°C pathways that can guide the next generation of NDCs. 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. Insights from experiences highlight the interlinkages between enhancing NDC ambition and implementation. Ambitious NDCs underpinned by robust implementation plans and accompanying investment plans can ensure NDCs are action oriented, implementation ready and investable. At the same time, adopting whole-of-government, whole-of-society approaches to NDCs can foster a sense of national ownership and increase social acceptance, leading to more ambitious NDCs and support subsequent implementation. The paper also explores potential guidance that could be relevant for negotiations on NDC features in 2024. While recognising the nationally determined character of NDCs, Parties could use these negotiations to provide clarity on new issues that have emerged since the Paris Agreement was adopted and on existing elements that could benefit from clarification. When addressing negotiations on NDC features, Parties may also want to consider a longer-term perspective beyond the next NDCs and links with other relevant negotiation processes on reporting and transparency.

This paper examines the current status of water availability, water demand, and influences from climate change in the European Union. It provides an overview of economic policy instruments to address water scarcity and manage water demand. Additionally, the paper explores policy options and considerations for addressing water scarcity and meeting Water Framework Directive (WFD) objectives. These considerations include balancing demand management and supply augmentation, managing water scarcity through robust allocation regimes, and increasing the use of agro-environmental measures and practices. The paper also discusses the principles and features of effective allocation regimes, drivers and incentives for allocation reforms, the hierarchy and sequencing of water use, abstraction charges, ensuring return flows and ecological flows, and improving the coherence of WFD measures and climate change policies. This is the third in a sub-set of four working papers within the Environment Working Paper series destined to support the further implementation of the economic pillar of the Water Framework Directive. The four papers are best read in combination and provide lessons which are relevant beyond the European Union.

This paper examines three sets of issues related to strategic investment planning and financing for water: i) Investment planning in an uncertain context; ii) The benefits of supplementing project level planning with a consideration for pathways of investments; iii) Facilitating access to a wider range of financing sources, most importantly commercial finance. Together these issues can enhance the performance of water-related finance, making the best use of available finance and assets, in a context marked by high-level of (public and private) debt and rising cost of finance. This is the first in a sub-set of four working papers within the Environment Working Paper series destined to support the further implementation of the economic pillar of the Water Framework Directive. The four papers are best read in combination and provide lessons which are relevant beyond the European Union.

This paper examines the concept of cost recovery of water services under the EU Water Framework Directive (WFD), including the different types of costs and cost-recovery mechanisms. It presents the state of play in the implementation of cost recovery in EU Member States, for financial, environmental and resource costs. It also analyses the political, societal and technical issues affecting cost recovery in EU Member States. Furthermore, it examines emerging options to recover rising costs, including ways to minimise costs and innovative arrangements to supplement existing funding streams. Finally, it questions how fit cost recovery is as a concept for emerging and future water-related challenges in the EU. This is the fourth in a sub-set of four working papers within the Environment Working Paper series destined to support the further implementation of the economic pillar of the Water Framework Directive. The four papers are best read in combination and provide lessons which are relevant beyond the European Union.

This paper examines the challenges and policy imperatives involved in implementing the Polluter Pays principle (PPP) in the context of the Water Framework Directive (WFD). It presents the state of play of the Polluter Pays principle in EU Member States. It also analyses the coherence with other policies in EU Member States, such as agriculture, land planning and industry. Furthermore, it examines the practical limitations of the Polluter Pays principle in relation to diffuse and legacy pollution. Finally, it questions how the principle fits into the Green Deal and future water-related challenges in the EU. This is the second in a sub-set of four working papers within the Environment Working Paper series destined to support the further implementation of the economic pillar of the Water Framework Directive. The four papers are best read in combination and provide lessons which are relevant beyond the European Union.

Companies are announcing pledges to increase their use of recycled content in their plastics products or packaging. But companies have historically failed to meet the goals that they have announced. OECD governments are adopting policies that will require the use of recycled content. There is some initial evidence that these policies strengthen recycling markets. Businesses have experienced some challenges in their initial efforts to comply due to a disharmonious range of definitions and targets. Additionally, there is an insufficient volume of useable recycled material in the market. This is especially an issue for food-contact packaging. Governments are facing limitations in what is feasible for monitoring and verifying compliance. This paper reviews current policies and methods for checking compliance. This review informs description of considerations for the design of recycled content policies and insights about their use.

The consumption of products, services and transportation has significant environmental consequences and account for the majority of global greenhouse gas emissions. Meanwhile, demand-side policy measures have the potential to reduce the environmental footprint of these activities by up to 40-70%. This Policy Paper draws on the OECD’s recent household survey on environmental policy and behavioural change to provide insights and policy recommendations for specific measures that can encourage more sustainable household consumption of energy, transport and food as well as more sustainable waste practices. The report was prepared in support of Japan’s 2023 G7 presidency.

This report outlines results from the initial pilot-testing of a Scorecard to assess the enabling environment for investment in water security, referred to as 'the Scorecard'. Developed in collaboration with the Asian Development Bank and partners, the Scorecard aims to identify conditions for attracting and maintaining investment in water security. The report outlines the Scorecard's rationale, scoring methodology, and presents its main components. It also provides results from seven Asian countries, namely, Bangladesh, Mongolia, Nepal, Pakistan, the Philippines, Uzbekistan, and Sri Lanka. Armenia's findings from a subsequent Eastern European pilot test are also incorporated. This is the first in a sub-set of working papers within the Environment Working Paper series presenting research on the enabling environment for investment in water security. It marks the beginning of a process to apply the tool and support policy reforms. The report refrains from offering policy recommendations, focusing on testing the scorecard's ability to assess conditions to attract and sustain investing in water security. For an illustration of country-specific policy recommendations, please refer to the forthcoming Environment Working Paper 'Enabling environment for investment in water security: Pilot test in the EU’s Eastern Partner Countries - Armenia case study'.
