Belgium has made progress in decoupling several environmental pressures from economic growth, in improving wastewater treatment and in expanding protected areas. Regions have achieved high levels of recovery and recycling, and have pioneered circular economy policies. However, further efforts are needed to progress towards carbon neutrality, reduce air and water pollution, reverse biodiversity loss and consolidate results of circular economy initiatives. Strengthening co‑ordination between the federal government and the regions, and among the regions, as well as enhancing policy coherence will be key factors of progress. As the COVID-19 emergency passes, recovery efforts should focus on putting the country back on track to meet the Sustainable Development Goals. Investing in low-carbon and natural infrastructure, promoting circular economy, strengthening carbon prices and phasing out environmentally harmful subsidies should be priorities. This is the third Environmental Performance Review of Belgium. It evaluates progress towards sustainable development and green growth, with special features on biodiversity and waste, materials management and the circular economy.

This report draws on more than 1 300 government budgetary transfers and tax expenditures providing preferential treatment for the production and consumption of fossil fuels as documented in the 2020 OECD Inventory of Support Measures for Fossil Fuels to track progress in reform of support. It sets out principal trends across 50 OECD, G20 and European Union (EU) Eastern Partnership (EaP) economies, including as resulting from the COVID-19 crisis and novel sectoral decomposition of Inventory data. It reports on developments in tracking and monitoring fossil fuel support in the context of the G20 and the UN Sustainable Development Goals, and with respect to enhancing the interpretation of tax expenditure data. Finally, the report offers a sequential framework to assist governments assess and address the effects of fossil-fuel support measures and their reform, given ongoing challenges in gaining traction for reform.

While COVID 19 has hit Peru particularly hard, with about 1.4 million cases as of March 2021, the pandemic further emphasised the importance of water and sanitation for health, the environment and the economy. The country is not yet on track to meet the targets of SDG 6 'Clean water and sanitation' by 2030, with 3 million Peruvians (9.2% of the population) lacking access to water services and 8.2 million Peruvians (25.2%) lacking access to sewerage services, and a large urban rural divide. In addition, between 2000 and 2020, floods affected an estimated 4.43 million people, while inadequate management of solid waste and some economic activities are amongst the causes of water pollution, leading to severe public health issues, and social conflicts. In the face of climate change and demographic growth, strengthening water governance in Peru is key for long term water security improvements. The report provides an analysis of water governance in the country and policy recommendations to: strengthen the multi sectoral approach to water; improve the use of economic instruments to protect and sustainably use water resources, its sources and related ecosystem services; and strengthen regulatory conditions to improved access to safe drinking water and sanitation in urban and rural areas.

In 2018, the city of Cape Town, South Africa, was close to the 'Day Zero', requiring all taps to be shut off and citizens to fetch a daily 25 litre per person. Though the day-zero was avoided, it is estimated that, at the current rate, South Africa will experience a 17% water deficit by 2030 if no action is taken to respond to existing trends. Lessons learned during that drought crisis have been valuable for the city to manage the short-term COVID-19 implications and design long-term solutions towards greater water resilience. As a result of a multi-stakeholder policy dialogue involving 100+ stakeholders from the city of Cape Town and South Africa, this report assesses key water risks and governance challenges in Cape Town, and provides policy recommendations towards more effective, efficient and inclusive water management building on the OECD Principles on Water Governance. In particular, the report calls for strengthening integrated basin governance, transparency, integrity, stakeholder engagement, capacities at all levels of government, financial sustainability and for advancing the water allocation reform to better manage trade-offs across multiple users.

This report analyses planned infrastructure projects, decision-making frameworks related to infrastructure development and strategic planning documents in the six countries of the EU Eastern Partnership: Armenia, Azerbaijan, Belarus, Georgia, Moldova and Ukraine. It compares current investment flows with countries' national development objectives to identify misalignments and provides policy-makers with recommendations to improve the integration of climate change and other environmental concerns into infrastructure development decision-making processes. The report presents a comprehensive overview of infrastructure investment, primarily in the transport and energy sectors, throughout the region and identifies the risks and opportunities emerging from current investment patterns.

The COVID-19 pandemic has acted as a magnifying glass on pressing water and sanitation challenges in African cities, stressing and widening inequalities, especially for the 56% of the urban population living in informal settlements, lacking basic handwashing facilities, and relying on public water points and shared toilets. Before the pandemic, African countries and cities were already facing mounting water challenges with, in Sub-Saharan Africa only, 418 million people lacking basic access to water supply and 717 million to sanitation, in addition to concomitant floods, droughts and pollution issues. Megatrends related to climate change, urbanisation and population growth add more pressure on water resources and require urgent attention for African cities to cope with future water challenges. Building on a Survey on Water Governance across 36 cities of all size in Africa, this report provides a regional overview of the allocation of roles and responsibilities for water management, the existence and implementation of institutional, policy and regulatory frameworks, as well as the critical governance gaps that need to be bridged in order to boost city government capacity to drive water security in the continent.

This working paper focuses on the role of monitoring, evaluation and learning (MEL) for promoting effective climate risk management. It aims to introduce a conceptual framework that governments and development co-operation providers can draw on when developing MEL frameworks for their interventions on climate risk management. The paper also presents existing methods and tools to address the technical challenges to developing such MEL frameworks. Further, it provides examples of good practice for adjusting or updating existing MEL frameworks in support of climate risk management. It contributes to the project Strengthening Climate Resilience: Guidance for Governments and Development Co-operation of the Organisation for Economic Co-operation and Development (OECD).

The COVID-19 crisis has amplified the urgency of addressing together the dual challenges of inequality and environmental degradation. This paper contributes to the debate on the inequalities-environment nexus by analysing the consequences of the environmental degradation and of environmental policies on four well-being dimensions: health, income and wealth, work and job quality, and safety. The analysis shows that the impacts of environmental degradation tends to be concentrated among vulnerable groups and households. At the same, the benefits and costs of environmental policies are also likely to be unevenly distributed across households. In this context, policy packages for an inclusive green transition should aim at: (i) mitigating the possible regressive impact of pricing environmental externalities, (ii) investing in human capital and upgrading skills to facilitate labour reallocation, (iii) addressing systemic inequalities with sectoral and place-based policies, (iv) ensuring efficient and responsive governance. The paper concludes by highlighting the need for an effective framework to measure progress towards a people-centred green recovery, and possible areas of future work.
