A recent study has assessed the lifecycle environmental impact during the production and use phase of three battery types for plug-in hybrid (PHEV) and full performance battery electric vehicles (BEV). The study indicates that newer lithium-ion (Li-ion) technologies outperform current nickel-metal hydride (NiMH) batteries and identifies processes contributing to 13 environmental impacts

By ranking the ???hazard potential??? of a wide range of chemicals used to make common plastics, Swedish researchers have highlighted which plastic polymers are made from the most hazardous chemicals. These should be prioritised for assessing the risk of causing human or environmental harm.

A new analysis of how to encourage pro-environmental behaviour highlights four effective techniques: goal-setting, prompts or reminders, witnessing the behaviour of others and introducing new behaviours that correspond with existing beliefs.

Global air quality will significantly deteriorate by 2050 unless further steps are taken to cut current emissions from human activities, according to recent research. Most people around the world will be affected by worsening air quality with hotspots of particularly poor air occurring in China, northern India and the Middle East.

A new German study suggests that residents??? level of satisfaction with their urban neighbourhood can be predicted from their perceptions of multiple and co-occurring burdens, such as poor air quality, lack of green space, noise and low cleanliness.

Citizen science is not only a tool for collecting valuable scientific data, it can also enable participants to reconnect with nature and encourage pro-conservation behaviour, new research has shown. Participants in a French butterfly monitoring programme reported making wildlife-friendly changes to their gardens as a result of taking part in the initiative.

A recent study has investigated how waste disposal sites in southern Italy have affected residents living nearby. Villagers reported being annoyed by odours, but the perceptions of residents living in the village closest to the facilities were possibly influenced by receiving financial compensation for the presence of the facilities.

Researchers have developed a new model to assess the health-related external costs arising from air pollution from ten major emission sectors. Applying the model at national and Europe-wide levels, they suggested that the major contributors to costs were industrial power production, agriculture, road traffic and domestic combustion.

Two tagged Cuvier's beaked whales have shown intense and lasting avoidance behaviours in response to military sonar. In the first study of this kind, the whales showed significant responses to sonar at volumes that are currently assumed in the US to have no effect on behaviour.

International agreements to reduce plastic use are needed to address plastic litter in the marine environment, as well as increased public awareness of the problem, according to scientists at a workshop on the EU Marine Strategy Framework Directive held in Italy in 2013. The issues discussed at the workshop have been summarised in a recent research paper.

The global production, trade and use of goods and services has a significant impact on the environment — and rates of consumption are rising. A new study combines two assessment methods to quantify the impact of European trade on the environment. It finds that, overall, the EU was a net importer of environmental impact from 2000 to 2010, that machinery, equipment and vehicles contributed most to the EU’s export impacts and that the EU’s trade balance (import impact minus export impact) is increasing over time. The two assessment methods complement one another well and could form the basis for future country or region-wide studies, suggest the researchers, by enabling a detailed analysis of individual steps within a product’s trade flow, while also providing a larger picture of the overall process.

Invasions of alien species are rising at an alarming rate, largely due to growing global trade and transport routes. Preventing the successful establishment of alien species by better understanding the factors determining success is a step toward limiting the threat of future biological invasions. Statistical modelling using observed bird invasion data — including location, event and species-level factors showed which factors were key to successful establishment by the alien species.

As 3D printing, also known as additive manufacturing (AM), begins to replace conventional manufacturing, the environmental impacts of its implementation must be assessed. This study conducted a life cycle assessment (LCA) to investigate the environmental and resource implications of using AM to manufacture the metal parts of an engine in a light distribution truck. In the LCA, the impacts of both present and possible future states of AM technology were compared with current conventional manufacturing. The results suggest that there are potential environmental and resource benefits1 to AM technologies, but that these benefits rely on the achievement of a clean energy source and further technological development.

Approximately 88 megatonnes (Mt) of food are wasted every year in the European Union, causing 186 metric tons (Mt) carbon dioxide equivalent (CO2-eq) — a universal measure for all greenhouse gases. The impact of food waste on the climate, acidification and eutrophication is around 15–16% of the environmental impact of the entire food chain. In developed countries, food waste is high at the point of consumption— so significantly reducing food losses would require a food-waste reduction in households and the food-services sector.

In Sweden, 63% of areas designated as Special Protection Areas (SPAs) for endangered birds are impacted by major roads or train lines, according to a new study. The research showed that 126 000 hectares (ha), or 4.2% of the SPAs, fall within 1 km of a road or train line, leading to a predicted 1% loss in bird abundance. The problem is greater in the south of the country, where 25.8% of land designated as SPA falls within 1 km of a road or rail line, representing an estimated 4 to 7% reduction in birds’ abundance within SPAs.

New research has compared the environmental impact of four alternative methods of water supply in Copenhagen. Results indicated that rain and stormwater harvesting is the most environmentally sound approach, whilst desalination currently has a large environmental impact, mainly due to electricity use. However, if freshwater extraction is included as an impact, the environmental credibility of desalination is improved.

A recent study has compared the environmental impact of a range of building materials. Energy consumption, carbon dioxide emissions and water demand can all be reduced by switching to renewable sources of energy, improving technologies and promoting eco-friendly alternative materials.

Environmentally responsible attitudes and behaviour do not necessarily translate into real benefits for the environment, according to the results of a new study. The study shows that people who think they are environmentally aware – and even those who, in some respects, seem to behave in an environmentally friendly way – actually have just as large an impact on the environment as other consumers.

A method has been developed to compare how EU Member States have implemented the Energy Performance Buildings Directive. It suggests that implementation varies widely across Europe but that the Czech Republic, Finland, Portugal and Slovakia have kept to the Directive’s aims and guidelines most closely, based on data available in 2009.

New research has assessed the environmental impact of gold production using life cycle assessment and estimated embodied energy and greenhouse gases, embodied water and solid waste burden that each tonne of gold produces, using various processes.

Using high-strength concrete in construction could help to reduce its impact on the environment, according to a study by French researchers. The researchers compared the environmental impacts of bridges built from ordinary and high-strength concrete and found that the high-strength solution had a lower impact on the environment overall.

A new concrete-reinforcement system, used by the LIFE INSU-SHELL1 project, replaces steel rods with non-corrosive textile structures to reduce the amount of concrete needed in construction. This nearly halves the global warming potential of traditional steel-reinforced concrete which is the largest producer of CO2 emissions in the building industry.

Staff in buildings that have been certified as ‘green’ under the LEED scheme are just as satisfied with their indoor working environment as people working in non-LEED buildings, according to research on commercial buildings. The study suggests that investment in the thermal and acoustic aspects of buildings, however, would further improve occupant satisfaction.

DEF CON and Black Hat announced today that their upcoming security conferences in Las Vegas this summer will no longer be in-person and are instead moving to an all-virtual event. [...]

The public can help assess the human impact on wild birds through amateur ‘citizen science’ networks, according to new research. Scientists evaluated the suitability of data collected by amateur bird-watchers for long-term monitoring of European bird populations. Their findings suggest that citizen data may significantly improve the accuracy of existing official survey methods, as well as help increase public awareness of wild bird conservation.

A review of the community-led research programme Open Air Laboratories (OPAL) – a UK national programme that brings scientists and communities together to investigate environmental issues – concludes that it benefits both science and the public. The public’s involvement not only raises their awareness of their relationship with the environment, but also contributes to securing a sustainable future.

Researchers have used the psychological concept of ‘commitment’, normally used to understand relationships between people, to investigate our relationship with the environment. The results indicate that an individual’s commitment to the environment is important in their ecological behaviour, for example, their willingness to use public transport and make sacrifices for the environment.

People who are committed to reducing their environmental impact at home do not necessarily behave in the same way when on holiday, according to a new study. The study presents a more complex view of consumer environmental behaviour than is often used to inform policymaking.

Standardised methods of categorising environmental data are needed at European and international levels for effective international policies. A recent study has concluded that a European framework that harmonises environmental data at the continental scale corresponds well with national classification systems, although some modifications may be needed to capture small-scale regional variations.

A new analysis of how to encourage pro-environmental behaviour highlights four effective techniques: goal-setting, prompts or reminders, witnessing the behaviour of others and introducing new behaviours that correspond with existing beliefs.

A recent study has investigated how waste disposal sites in southern Italy have affected residents living nearby. Villagers reported being annoyed by odours, but the perceptions of residents living in the village closest to the facilities were possibly influenced by receiving financial compensation for the presence of the facilities.

An overview of research into ‘nudge’ theory and practices has recently been presented. While there is much evidence to show how humans make decisions, translating these psychological and economic insights into viable policy instruments that encourage behavioural change remains challenging, the authors conclude.

Campaigns which remind individuals of the environmentally-friendly actions they already perform may motivate them to even more pro-environmental behaviours, new research suggests. If people identify themselves as environmentally-friendly, they are more likely to carry out green actions, even in the absence of any incentive.

Effective ‘knowledge exchange’ - the process of producing, sharing, understanding and using knowledge - is vital to good environmental management. New research has uncovered five principles for this process which could help researchers, decision makers and other parties work together to better manage environmental change.

Integrated environmental modelling (IEM) is an organised approach to streamlining the movement of scientific information from its research sources to its application in problem solving, according to a study that envisions a global-scale IEM community. The researchers present a roadmap for the future of IEM, describing issues that could be addressed to develop its potential even further, such as how best to integrate diverse stakeholder perspectives and appropriate guidelines for ‘problem statements’.

The impact of air quality on public welfare is important to policy development. However, it is difficult to make a clear link between the two when air pollution tends to be reported at a country level and wellbeing is an individual measure. A new study takes a step further towards linking the two by analysing regional level air quality across the EU and relating it to levels of life satisfaction.

The phrase ‘emerging risk’ has been widely used in scientific and business communities, but without consensus on how to define and govern such a risk. A new study proposes that risk emergence goes through four states, from ‘unknown unknowns’ to risks that are fully in the public domain. Understanding emergence as a process can help decision makers detect and manage risks on the basis of scientific evidence.

Long ago, one great ocean flowed between North and South America. When the narrow Isthmus of Panama joined the continents about 3 million years ago, it also separated the Atlantic from the Pacific Ocean. If this took place millions of years earlier, as recently asserted by some, the implications for both land and sea life would be revolutionary. Aaron O'Dea, staff scientist at the Smithsonian Tropical Research Institute (STRI), and colleagues writing in Science Advances firmly set the date at 2.8 million years ago.

A recent study has revealed that grassland plots planted with a mixture of several agricultural plant species produced a greater yield than plots planted with a single species. The findings provide valuable evidence for scientists, farmers and policymakers who strive to increase the productivity of grassland, while reducing input of nitrogen fertilisers.

The development of Green Infrastructure (GI) in a UK case study has been researched in a recent study. Some issues caused by an imbalance in stakeholder power and conflicting roles played by major stakeholders were identified with the project. Stakeholder participation is central to the concept of GI and the research reiterates the importance for those implementing GI to ensure that participation is effective and balanced.

Over 8% of land in Europe could be at moderate-to-high risk of wind-driven soil erosion, a new study has estimated. In the first assessment of its kind, the researchers produced maps which show wind erosion risk across 36 countries. This information could help guide actions to tackle land degradation.

Wildfires in the Mediterranean region are a significant threat to human life and the natural environment and cause considerable economic damages. Recent research from Italy suggests that different types of land cover influence the timing of wildfires throughout the year and this knowledge can be used to improve fire risk assessment and prevention strategies.

The European Directive on the assessment and management of flood risks1 (the Floods Directive) represents a shift towards holistic and catchment-oriented management of flood risk and is likely to prompt changes to policy in many Member States. New research from Germany suggests that effective implementation of the Floods Directive is likely to be greatly aided by the participation of stakeholders and communication between groups.

Soil erosion after wildfire can be substantially reduced by using a combination of sowing grass seeds and protecting the soil with a layer of straw, a Spanish study suggests. The authors of the research found that, although seeding alone made little difference, the combination of straw mulch and seeding reduced soil erosion by 93%.
