This report presents global projections of materials use and their environmental consequences, providing a quantitative outlook to 2060 at the global, sectoral and regional levels for 61 different materials (biomass resources, fossil fuels, metals and non-metallic minerals). It explains the economic drivers determining the decoupling of economic growth and materials use, and assesses how the projected shifts in sectoral and regional economic activity influence the use of different materials. The projections include both primary and secondary materials, which provides a deeper understanding of what drives the synergies and trade-offs between extraction and recycling. The report projects a doubling of global primary materials use between today and 2060. Population and converging per capita income growth drive the growth in materials use. However, structural change, especially in non-OECD countries, and technology improvements partially dampen that growth. Metals and non-metallic minerals are projected to grow more rapidly than other types of materials.

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 aims to provide policy makers with a comprehensive examination of 'project pipelines', a common concept in infrastructure planning and investment discussions, and one which has become a focal point in countries’ efforts to implement their climate commitments. The analysis is structured around some basic but important guiding questions, including: What is meant by project pipelines? How can we characterise them? What concrete approaches and actions can governments and other public institutions take to develop project pipelines and mobilise private finance into these projects? This close look at pipelines suggests that they can only be as robust as the investment-ready and bankable projects that constitute them, as effective as institutions that deliver them, and as ambitious as the objectives to which they are linked. Through a series of case studies, the report highlights that while governments and public institutions are already taking actions to develop robust pipelines in a range of country settings, these pipelines nevertheless need to be strengthened significantly to meet long-term climate mitigation objectives. Good practices pioneered by the countries and actors in the case studies can provide models for governments to adapt and bolster their own efforts.

This report looks at the fiscal, environmental and social impacts of energy subsidy reform in Moldova with a particular focus on energy affordability. Reduced value added tax (VAT) rate on natural gas consumption and a VAT exemption on electricity and heat consumption by domestic users represent the largest fossil-fuel consumer subsidies in Moldova. Reforming these will imply an increase of the VAT rate, which will lead to an increase of gas, electricity and heat tariffs for households, and will in turn affect household consumption levels, related expenditures and energy affordability. If reform measures are to work, they will need to be accompanied by a carefully-designed social policy to protect poor households.

The need to mainstream biodiversity into economic growth and development is being increasingly recognised and is now also firmly embedded in the Sustainable Development Goals. Drawing on experiences and insights from 16 predominantly megadiverse countries, this report examines how biodiversity is being mainstreamed in four key areas: 1) at the national level, including national development plans and other strategies, institutional co-ordination and national budgets; 2) the agriculture, forestry and fisheries sectors; 3) in development co-operation; and 4) the monitoring and evaluation of biodiversity mainstreaming and how this could be improved.

Plastics have become one of the most prolific materials on the planet: in 2015 we produced about 380 million tonnes of plastics globally, up from 2 million tonnes in the 1950s. Yet today only 15% of this plastic waste is collected and recycled into secondary plastics globally each year. This report looks at why this is the case and what we can do about it, as the pervasiveness of plastics is becoming an urgent public health and planetary problem. Not only is the diffusion of waste plastics into the wider environment creating hugely negative impacts, but plastics production emits approximately 400 million tonnes of greenhouse gas (GHG) emissions annually as a result of the energy used in their production, transport, and final waste treatment. Improved plastics collection and recycling represents a promising solution to these concerns.

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.
