The OECD and the Directorate-General for Environment, the European Commission department responsible for EU policy on the environment, joined forces to examine current and future water-related financing challenges faced by EU member states. These include investments needed to comply with EU regulation for water supply, wastewater collection and treatment, and flood protection.

This report presents a summary of the key challenges and opportunities related to financing that contributes to water security and sustainable growth distilling insights from the Roundtable on Financing Water and related analyses. It covers a broad range of water-related investments, including water and sanitation services, water resources management, agricultural water and managing water-related risks (“too much”, “too little” and “too polluted”).

The Toolkit for Water Policies and Governance compiles policies, governance arrangements and related tools that facilitate the design and implementation of water management practices in line with the OECD Council Recommendation on Water.

The OECD and the Directorate-General for Environment, the European Commission department responsible for EU policy on the environment, joined forces to examine current and future water-related financing challenges faced by EU member states. These include investments needed to comply with EU regulation for water supply, wastewater collection and treatment, and flood protection. As part of the research, new data was produced on current levels of expenditure for water supply, sanitation and flood protection, as well as on projected needs. It supported a comparison across member states and substantiated tailored policy discussions in selected countries and at European level. This report captures the rationale for the research, the main quantitative outcomes and the policy issues and recommendations that derived from this two-year co-operation. Lessons from Europe outlined in this report can inspire similar research and policy discussions in other parts of the world.

Water is a finite and non-substitutable resource. As the foundation of life, societies and economies, it carries multiple values and benefits. But unlike most other natural resources, it has proven extremely difficult to determine its true 'value'. The 2021 edition of the United Nations World Water Development Report, titled "Valuing Water" assesses the current status of and challenges to the valuation of water across different sectors and perspectives and identifies ways in which valuation can be promoted as a tool to help improve its management and achieve global sustainable development.

Investing in Water and Growth: Recent Developments and Perspectives addresses this conundrum in a cohesive and practical way. It is a one-stop shop for understanding why the financing of water-related expenditures matters, what is at stake, and the options available to ensure water-related investment needs are properly financed in ways that generate benefits for communities and contribute to sustainable growth. The book combines the perspectives of policymakers, economists and financiers in a unique, multidimensional and multidisciplinary approach. The book is structured into four distinct parts that target a specific set of questions and content development. Each section of the book has a multidisciplinary approach that provides a robust overview of key issues. The book combines different types of knowledge – from theory to practice, providing a full view of the topics discussed. - Includes numerous examples and real-world case studies - Discusses the concepts of planning, the planning process, integrated planning and public involvement - Synthesizes key evidence and arguments for investing in water security and sustainable growth

As in most OECD countries, the pandemic triggered a deep recession in Portugal and put huge pressure on the healthcare system. The policy response helped to weather the shock and the recovery has gained speed, sustained by progress in vaccination.

Despite remarkable improvement in water supply and sanitation services, Estonia faces finance and investment challenges to keep up with social expectations and environmental health regulations. With downward demographic trends expected to affect water utilities revenues and the projected phasing out of EU water funding, which was essential in the rapid improvement of service provision over the last two decades, substantial efficiency gains are required to transition towards sustainable water service provision.

Ireland’s progress in delinking the economy from environmental pressures has been uneven in the last decade. Greenhouse gas emissions, waste generation and nutrient pollution rose with strong economic growth between the mid-2010s and the inception of the COVID‐19 pandemic.

The Environmental Tax Policy Review of Andalusia provides a detailed review of the environmentally related tax framework in the areas of greenhouse gas emissions and air pollution, water usage and pollution, and waste and circular economy in the Autonomous Region of Andalusia, Spain.
