An overview of ‘material efficiency’ is provided in a recent study, which assesses a range of technical and sociological approaches to material efficiency. The need for drastic efficiency improvements is highlighted by the researchers, as well as cuts in the total amount of materials used.

A new tool to help planners choose urban designs that positively influence flows of energy, carbon, water and pollutants in cities is presented in a recent study. It is designed to integrate scientific knowledge into the planning process and support cities in achieving sustainability objectives.

Investment in restoring coastal habitats is an effective way of creating new jobs, recent research has found. The US study analysed 44 ‘blue infrastructure’ restoration projects and found that, on average, 17 jobs were created for every US$ 1 million (€0.76 million) spent on these developments. This is more jobs than are created in the coal, gas or nuclear energy industries, where the same investment only results in 4-7 jobs.

Local context may have more influence over public acceptance of restrictive policies, such as road tolls and parking fees, than factors such as age, gender or education, a new study suggests. The researchers analysed public reaction to Norwegian policies used to reduce car use and found that there were three aspects of local context that were particularly important: local urban development policies, sense of local identity, and public understanding of the problems.

Public support for pay-as-you-throw (PAYT) waste schemes is significantly higher among those who have actually experienced them, finds new research. The study indicates that there is less resistance to such schemes, which charge householders a fee that varies with the amount of waste collected, once they have been introduced.

How can stakeholders best be involved in the implementation of the EU Floods Directive? According to recent research examining Germany as a case study, three types of strategy are being pursued across the country’s 16 federal states: the first draws on Water Framework Directive (WFD) procedures, the second meets only minimum requirements for participation and the third involves stakeholders more intensively.

There are adequate resources to implement the Marine Strategy Framework Directive (MSFD) in Europe, a recent study concludes. However, more clarity is needed on the roles of different institutions at EU, regional and national levels in implementing the Directive.

A pilot Marine Spatial Planning (MSP) project in the UK has found MSP to be a useful approach in managing marine waters sustainably. Sharing the knowledge and experiences gained in developing the Shetland Islands’ Marine Spatial Plan (SMSP) can help other authorities in the process of developing similar plans, says the project team.

The Irish public are sceptical of government and industry’s ability to manage the marine economy, finds a survey. However, they place a large amount of trust in scientists. The research also indicates that people living in Ireland have a reasonable level of knowledge of the importance of different marine ecosystem services.

Plans for new Marine Protected Areas (MPAs) need to consider social impacts alongside economic and environmental impacts, according to a recent study, which found that an MPA in the UK has increased some tensions within its local community. The researchers suggest that collaborative management could also help increase support for MPAs and reduce stakeholder conflict.

We need a better understanding of how the public perceive the risks of population growth, a new discussion paper argues. Research into public perceptions of the environmental and social challenges of population growth could guide behavioural-change communications to help limit growth and manage the difficulties. Specific communication issues include how to convey statistical information and the complex impacts of population growth.

More than 200 pieces of English and EU-wide marine environmental legislation have been analysed in a recent review. While complex, the legislation adequately covered all areas of the marine environment, the authors conclude. However, there is opportunity to remove overlap and conflicts between different legislation and improve cross-border co-operation.

A new tool has been developed to map the sensitivity of seabirds to offshore wind farm development. The Seabird Mapping and Sensitivity Tool (SeaMaST), currently for use in English waters, combines information on the sensitivity of seabird species to wind turbines with data on the birds’ distribution. It provides maps that can be used for both the offshore wind farm industry and marine spatial planning.

A Portuguese waste management system for packaging has brought a range of environmental, economic and social benefits, according to a recent study. One of the scheme’s main achievements was that it avoided around 116 kilotons (kt) of CO2 equivalent emissions in a single year, equal to the emissions associated with the electricity use of 124 000 households. These emissions were largely circumvented because the system recovers large amounts of energy and materials from the waste packaging.

Improving the efficiency of industries and products has not led to overall reductions in the consumption of goods and services, a new study has found. The research looked at the historical relationship between efficiency improvements and resource consumption across 10 different activities, including electricity generation and passenger air travel. However, shorter decade-long periods, where efficiency improvements outpaced resource consumption, suggested that legislation and price pressures could be effective at reducing resource consumption.

Policy efforts to decrease energy consumption by improving efficiency may be lessened by rebound effects. New research on household energy consumption indicates just under half EU countries (plus Norway) have rebound effects above 50%, and six are over 100% which means the efforts to increase efficiency backfire, i.e. they increase, rather than reduce, overall household energy consumption. There is a need to think critically about a policy response to the rebound effect and gain a better understanding of why it occurs.

A human rights ‘protection gap’ exists for people forced to migrate by environmental stress and climate change, according to researchers. The lack of a legal framework and practices to protect ‘environmental refugees’ stems from the historic and political context of migration issues — and land access rights more broadly — the researchers say in a recently published paper.

Marine protected areas (MPAs) are widely used to safeguard marine ecosystems across Europe. This study investigated the effect of a partially protected area (PPA) off the coast of Norway on a population of Atlantic cod (Gadus morhua). The PPA reduced the number of deaths due to fishing, increased survival and stimulated movement to surrounding areas. The authors say that preventing fishing altogether would increase survival even further and recommend no-take zones in areas where populations are severely reduced.

Recycling of excess heat, via ‘district heating’, has the potential to improve energy efficiency in Europe. This study mapped excess heat and demands for heat in EU27 Member States to identify regions suitable for the large-scale implementation of district heating. The authors identified 63 ‘heat synergy regions’, generally large urban zones, which generated almost half of all excess heat generated in the EU27.

Marine protected areas (MPAs) have well-reported ecological benefits, but may also have important socioeconomic effects on local communities. Existing methods to assess these effects have been hampered by a number of limitations. This paper describes a new framework to monitor and assess the socioeconomic effects of MPAs, which overcomes many of these limitations to provide greater value for decision makers.

Agricultural land use presents a number of environmental challenges, which the European Commission is committed to addressing through a range of agri-environmental policies. A new study points to the importance of aligning agri-environmental policies with farmers’ needs and operations. Using the case of land clearing in Finland, the research underlines the importance of incorporating input from grassroots stakeholders into policy design.

Industry has traditionally claimed that strict environmental regulation has a negative effect on its competitiveness. However, a recent theory proposes it may actually increase productivity and innovation. This study used a large database of inter-sectoral transactions to investigate the effect of environmental taxation on manufacturing businesses across Europe. The findings show that environmental regulation can increase innovation and productivity.

‘Network bridging organisations’, such as farmer unions, Regional Nature Parks and Local Action Groups, promote cooperation between farmers, non-state collective actors and state actors under the Common Agricultural Policy. This study finds that farmers who have regular contact with these organisations show a higher commitment to long-term practice change. This could represent an opportunity to improve the effectiveness of payments for environmental services in Europe.

Effective regulation of genetically modified organisms (GMOs) calls for monitoring of the potential environmental risks. This study explored whether the German permanent soil monitoring programme could be a useful tool for this purpose. The researchers say the programme has potential to monitor the effects of GMOs on local soil communities, but that adaptations would be necessary.

Governments and funding bodies are increasingly evaluating the ‘impact’ of academic research. There are growing discussions about impact – what it means, and how it can be demonstrated – and it is a challenge to evaluate impact on society. This study investigated the broader benefits of scientific research, beyond technology development, to support more comprehensive evaluations of science.

Researchers have provided a set of guidelines to help policymakers, designers and operators develop sustainable solutions for energy-storage systems for electricity grids. The guidelines cover a range of energy-storage technologies and grid-integration options.

Norway has the highest battery-electric vehicle market share of any country worldwide. A new study investigated the incentives that have persuaded consumers to purchase electric vehicles in Norway, revealing that up-front price reductions (such as exemptions from purchase tax) are the most powerful incentives.

A large proportion of ships are recycled on the beaches of developing countries in Asia. This study considered shipbreaking in Bangladesh, using critical scenario analysis to explore different futures for the industry and its workers. The paper suggests that a radical shift in socioeconomic and political structures is needed to enable environmentally sound practices while retaining employment opportunities for local people.

When broken down, ships can release hazardous substances into the environment. This study investigated the environmental impact of shipbreaking in one of Europe’s few ship recycling yards, based in Portugal. The results reveal large differences between assessment methods and show that environmental impact depends on composition rather than size or class.

An inventory of materials used in ship construction could minimise waste and increase ships’ recycling rates and resale value, according to the Sustainable Shipping Initiative (SSI). Although extra data management would be required on the part of suppliers, manufacturers and owners, it would help make the industry more efficient and future-proof with regard to developments in international legislation on ship building.

Global interest in urban agriculture is growing. However, the importance of local context is not reflected in current governance approaches, argues a new study which evaluated urban agriculture in Belgium and Poland. The authors say that considering city-specific factors can help urban agriculture achieve its full potential, and recommend a broader policymaking strategy that considers the benefits beyond food production.

A SWOT (strengths, weaknesses, opportunities, threats) analysis of efforts to combat environmental crime in the EU has been recently conducted. It highlights a number of opportunities for improvement, including better crime data gathering across the EU and enhanced cooperation between Member States.

Alongside fines, prison sentences are important punishments for environmental crime, but there is uncertainty about how often they are used. This study summarises evidence from several countries, showing that prison is indeed a genuine threat for environmental criminals, but that more needs to be done to improve its credibility.

Administrative sanctions against environmental crime, such as fines, are generally easier and cheaper to implement than criminal punishment methods, such as prison sentences. This study explored enforcement methods for environmental crime in four Western European areas: Flanders (Belgium), Germany, the Netherlands and the UK. Based on their findings, the authors say it is most cost-effective — and may increase deterrence — to use both forms of enforcement.

Policymakers often have to make decisions under great complexity, uncertainty and time pressure. A new study presents a support tool for the first stage of policymaking: identifying and exploring alternatives to solve problems. The software tool, called QUICKScan, increases the speed of this process and combines the input of many stakeholders in participatory workshops. It has been applied 70 times in 20 different countries, for a wide range of environmental policy issues.

The effects of market regulation and environmental policy on eight types of renewable energy in the EU are identified in a study which examines nearly three decades’ worth of data. The researchers found that reducing entry barriers is a major driver of renewable energy innovation and that the ability of environmental policy to promote renewable energy innovation depends on the technology; for example, quota systems appear to work better with older technologies.

Agri-environment schemes (AES) are widely researched; some important issues, however, remain unstudied. Researchers have investigated some of these issues using a sample of olive growers in southern Spain. Their study reveals the level of monetary incentive needed for farmers to accept an ‘ecological focus area’, and a general unwillingness to participate collectively. These results could help policymakers design more cost-effective AES.

Researchers have developed a new indicator for policymakers, which shows the strength of renewable-energy technologies for electricity production in a country’s energy security. They compare their Renewable Energy Security Index (RESI) to the carbon footprint, in that it is easy to report and practical to use in energy policy.

International trade has increasingly relied on material resources since the 1990s, according to a new study. The research used the most detailed global computer model available for capturing the effects of international trade on the environment and on the efficiency of resource use between 1995–2011. Sharp increases in the trade of cheap ‘fast fashion’ and mass market electronics are highlighted as two of the fastest growing drivers of this change in material inefficiency.

Milan and Seoul are considered by many as pioneering examples of cities in promoting a sharing economy. A new study has analysed governance in these two cities, and concludes that they have both laid the right foundations for a sharing economy to develop. The researchers propose that while such economies carry risks, they are also able to benefit the economy, environment, and society.

A study into how agriculture can help humanity meet the United Nations’ Sustainable Development Goals finds that research in Europe on agricultural land systems largely omits key priorities from policy and practice. The researchers identify 32 variables that researchers, policymakers and practitioners collectively prioritise when it comes to European agricultural systems, and suggest that future research includes these in order to more comprehensively analyse trade-offs and identify opportunities for sustainable progress.

To better understand the social and ecological implications of the non- food sector of the EU’s expanding bioeconomy, an economy which is based on the production and conversion of renewable biological resources into products and energy, a study has assessed the global cropland footprint of the region’s non-food products. The results show that the EU was the world’s biggest consumer and importer of these products from 1995 to 2010: two-thirds of the cropland required to satisfy the EU’s non-food consumption is located elsewhere in regions including China, the USA and Indonesia, bringing potential impacts for distant ecosystems. These findings can inform EU policymaking and support the EU Bioeconomy Strategy.

The German Renewable Energy Sources Act was introduced in 2001 to encourage an increase in renewable energy supply. Since then, supply has increased from 7% (in 2001) to 37% (in 2017. Wind energy is an important part of Germany’s renewable energy production — but deploying sufficient turbines to achieve the climate goals requires a large amount of raw materials, many of which are metals in limited supply. This study found copper and dysprosium to be the most critical of these metals, as they could face future bottlenecks and are essential elements in present and future turbine design.

The announcement of a new no-take fishing zone in the Pacific led to a 130% increase in fishing activity ahead of its implementation, satellite data reveal. Although fishing activity dropped to zero once the marine protected area (MPA) came into effect just over a year later, the study warns that the pre-emptive short-term surge in fishing could have caused long-term ecological damage.

A new study has analysed how to reduce the environmental footprint of EU trade by preferentially importing goods from countries that have greener production processes. The study concludes that the environmental impacts of 200 product groups imported into the EU could be considerably reduced in this way. For example, water consumption caused by these imports could be cut by 72%, and land use by 65%.

A more circular economy could reduce global levels of raw material extraction by 10% by 2030, a new study suggests. It could also drive a slight increase in overall employment levels, but the types of jobs available would change significantly, moving away from low- and medium-skilled work in the manufacturing and mining sectors and opening up more opportunities for medium- and high-skilled jobs in the service sector.

Reducing the amount of phosphorus used in agriculture could go a long way in meeting the Baltic Sea Action Plan (BSAP) targets. A Swedish evaluation of measures for reducing agricultural phosphorus suggest phosphorus inputs to the sea could be cut by 180 tonnes per year, or about two-thirds of Sweden's target.

Water shortages are an urgent issue in many areas of the world and it is likely that the construction of desalination plants will increase to meet the rising demand for fresh water. A new study has evaluated a combined process to manage both the brine by-product from desalination plants and capture carbon dioxide.

A new study has analysed the impact of industrial and agricultural changes on nutrients in Estonian rivers. The results indicated that there were significant reductions in nitrogen in one third of the sites, significant reductions in phosphorus in a quarter of sites and significant reductions in both nutrients in nearly a tenth of sites.

Solar-powered irrigation that delivers water directly to plant roots could help ensure food security in Africa, say researchers. Their study in the Sudano-Sahel region of West Africa indicated that this irrigation method could increase both household income and nutritional intake, particularly during the dry season.
