This report discusses the main results of a project on how an influx of funds could spur development of cleaner public transport, and reduce air pollution and greenhouse gas (GHG) emissions in large urban centres in Moldova, by providing an analysis for designing a green public investment programme in this sector. This sector represents an opportunity for Moldova to address key objectives in its environmental and climate-related policies as part of the country’s ambitions to transition to a green economic path of development. The investment programme is also designed to support the modernisation of the urban transport fleet in the country and stimulate the domestic market to shift to modern buses powered by clean fuels. The programme is foreseen to be implemented in two phases: the first covers the cities of Chisinau and Balti and the second extends to areas outside of the initial pilot city centres (pilot city suburbs as well as inter-city transport). These investments are expected to result in significant environmental, public service and socio-economic benefits.

This report aims to support the development of a sound economic regulatory system for the water supply and sanitation (WSS) sector in the Republic of Moldova (hereafter 'Moldova'). The prevailing policy framework calls for drastic developments in WSS to modernise and optimise WSS systems and improve operational efficiency (non-revenue water, staff-output ratios etc.) – in line with domestic and international commitments (including the Association Agreement with the European Union, the Sustainable Development Goals, the Paris Agreement and the national WSS strategy). This report outlines ways and means for strengthening the capacity of the Moldovan government to provide sound regulation and that of WSS operators to deliver higher standards of service while ensuring the affordability of WSS services. Such a transition cannot happen overnight. It requires a sound economic regulatory system conducive to affordability, cost recovery and debt servicing, and a realistic performance improvement path for water utilities.

This report assesses the key bottlenecks within the water-energy-land-food nexus in Korea, and proposes policy recommendations and governance arrangements to future-proof environmental integrity and enhance sustainable growth. The increasing pressure caused by urbanisation, industrialisation, population growth and climate change in Korea has led to more land consumption and augmented water supply, at the expense of the environment and at a high cost for public finance. Korea has engaged with the OECD via a national policy dialogue to explore best practices from the wider international community to better manage the nexus at the river basin scale.

This report provides a new perspective to the nature of urban sprawl and its causes and environmental, social and economic consequences. This perspective, which is based on the multi-dimensionality of urban sprawl, sets the foundations for the construction of new indicators to measure the various facets of urban sprawl. The report uses new datasets to compute these indicators for more than 1100 urban areas in 29 OECD countries over the period 1990-2014. It then relies on cross-city, country-level and cross-country analyses of these indicators to provide insights into the current situation and evolution of urban sprawl in OECD cities. In addition, the report offers a critical assessment of the causes and consequences of urban sprawl and discusses policy options to steer urban development to more environmentally sustainable forms.

This report provides an assessment of spatial inequalities and segregation in cities and metropolitan areas from multiple perspectives. The chapters in the report focus on a subset of OECD countries and non-member economies, and provide new insights on cross-cutting issues for city neighbourhooods, such as the patterns of segregation across income groups, migrant concentration and diversity across cities of different sizes, the role of public transport accessibility in widening intra-city inequalities, and the expected path dependency on outcomes related to segregation. The report also discusses methodological alternatives for measuring different dimensions of inequality and segregation across cities, and highlights the role of public policies in bridging urban divides and the relevance of the scale of analysis in order to make sound international comparisons.

This toolkit, based on existing good practice, aims to help governments in the EU’s Eastern Partnership (EaP) countries (Armenia, Azerbaijan, Belarus, Georgia, Moldova and Ukraine) to design and implement key instruments to promote environmental compliance and green business practices among small and medium-sized enterprises. Reducing the environmental impact of SMEs in both manufacturing and services is a key success factor in greening the economy. At the same time, improving environmental performance is a significant business opportunity for SMEs as important suppliers of goods and services. Developed under the EaP GREEN project, this report will be of interest to environmental and economic ministries, as well as business associations and non-governmental and academic institutions in EaP countries.

More than 8 000 large multi-purpose water infrastructures (MPWIs) around the world contribute to economic development, as well as water, food and energy security, encompassing all human-made water systems including dams, dykes, reservoirs and associated irrigation canals and water supply networks. Focused on the specific case of the Shardara MPWI located in Low Syr-Darya Basin, South Kazakhstan and Kyzyl-Orda oblasts (provinces) of Kazakhstan, this report looks at the choice and design of MPWI investment strategies that ensure a high economic return on investments and potential bankability, based on application of a computer model and lessons learned from 15 international MPWI case studies.
