The EU Joint Research Centre has produced a new part of the handbook that provides guidelines for developing and using Life Cycle Assessments (LCA), which evaluate the environmental impacts of products, focusing specifically on life cycle impact assessment (LCIA). It recommends that assessments should be comprehensive, accessible and easy to apply in order to make LCA a more mainstream concept in decision-making.

Increasing the use of recycled materials could substantially reduce the carbon footprint of plastic packaging, research suggests. A new study of the life-cycle of plastic trays has shown that increasing the proportion of recycled material could lead to a significant reduction of greenhouse gas emissions.

International rail vehicle construction company, Stadler, disclosed that it was the victim of a cyberattack which might have also allowed the attackers to steal company and employee data. [...]

Sustainable management of complex ecosystems requires clear understanding of uncertainty. However, scientific guidance documents show a lack of clarity and coherence regarding uncertainties and tend to focus solely on the need for more data or monitoring, new research indicates. The researchers suggest that scientific guidance should recognise uncertainty as an inherent part of any complex ecosystem.

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.

Excess nutrients in sea water can cause eutrophication, a major environmental concern. Shellfish species such as mussels can ‘soak up’ some of these nutrients. A recent Swedish study examines the cost-effectiveness of mussel farming in the Baltic Sea as a method of reducing nutrient concentration and compares its potential with other methods of combating eutrophication.

The health risks to humans of using recycled water to irrigate crops needs to be carefully managed. New research has demonstrated that ???managed aquifer recharge??? can be just as effective as conventional water treatments in improving the quality of recycled water for use in irrigation.

The presence of plastics in aquatic environments is a growing concern across the EU. This study explored the amount of microplastic particles present in raw and treated water at three water-treatment plants in the Czech Republic. While treated water contained fewer particles than raw1 fresh water, the amount found in treated water was not negligible, and largely comprised tiny particles of <10 micrometres (μm) in diameter. Ways to filter microplastics from potable water must be identified and their risk to humans, sources and routes into drinking water determined, say the researchers.

A recent study has assessed the sustainability of different nuclear cycle scenarios in Europe, and suggests trade-offs are required between reducing the amount of uranium fuel needed, costs and proliferation risks.

The Fukushima accident in Japan has sparked international debate on nuclear energy. A new study has identified five factors which may have influenced the contrasting energy policy responses to the incident in the UK and Germany. Following the disaster, the UK is continuing to back nuclear power generation, whilst Germany is withdrawing support.

Regulators should establish a process to consider the full lifecycle greenhouse gas (GHG) emissions of electric vehicles, according to a new US study. This would help ensure that vehicle emissions regulations are placed on a sound scientific basis, manufacturers continue to improve the efficiency of electric vehicles, and the full benefit of regulations to limit GHG emissions from vehicles are realised, say the researchers.

Researchers have used a new comprehensive life cycle approach to estimate greenhouse gas (GHG) emissions from road construction. When applied to four projects in Spain, the results suggest improvements could be made in the use and efficiency of off-road machinery, the choice of materials and restoration of ecosystems.

The greenhouse gas (GHG) emissions produced during the decommissioning phase of nuclear power plants may have been underestimated in previous assessments, new research suggests. The study estimated that the decommissioning process for a German plant resulted in 1 651 265 tonnes of CO₂ (or equivalent) emissions, or 0.825 tonnes of CO2 equivalent per tonne of waste. While the researchers acknowledge that impact is highly dependent on the unique characteristics of each decommissioning project, these results raise questions as to whether this phase has been accurately assessed in earlier research.

Although life cycle assessment (LCA) is a widely accepted method for supporting decision-making, it can face difficulties when being translated into practical life cycle management. A recent case study on local waste management has led to the development of several principles to ensure that LCAs are understandable and applicable.

End-of-life-vehicles are a major stream of waste in the EU. A new study investigates the costs of landfill, advanced thermal treatment and incineration of waste from vehicle recycling factories and suggests that the factories are profitable, even while operating under strict conditions designed to meet the requirements of the EU’s Directive on End-of-Life vehicles.

Life cycle assessment (LCA) can measure the environmental impact of the different stages of a ship’s life cycle, from design to dismantling. This assessment focused on the impact of recycling the metal parts of a ship and did not consider the crucial impact of the hazardous materials present on board. The results showed that re-use of metals had environmental benefits, but overall these were small compared to the environmental impact of other life cycle stages, such as operation.

Recycling has significant environmental benefits and is key to a circular economy. The EU has set a goal for Member States to recycle 50% of their municipal waste by 2020 and plans to set a 65% target for 2030, although progress towards this goal is variable. This study assessed a waste separation scheme in Malta, a Member State with traditionally low levels of recycling. Even though mixed waste was collected more frequently and for free, residents contributed to the voluntary recycling scheme, with participation increasing over time. This study provides useful insights for developing voluntary policy approaches.

Aeration technologies designed to help landfill waste break down faster need to be refined in order to reduce pollution, greenhouse gas emissions and the long-term costs associated with landfill. This is according to a recent review of landfill aeration, which outlines some of the different systems currently available and highlights the need for better monitoring and sharing of data.

Recycling offers a promising means of supplying the rare earth elements neodymium and dysprosium, used in computing and low-carbon technologies, research suggests. If recycling infrastructure and technologies are prepared now to deal with the larger volumes of high-tech waste expected in the future, 7-9% of global demand for these critical elements could be met by recycling by the year 2030.

Desktop three-dimensional (3D) printers, available for use in offices and homes, can release between 20 and 200 billion ultra-fine particles (UFPs) per minute, finds new research. UFPs may pose a risk to health, and the study’s authors recommend caution when operating 3D printers inside unventilated or unfiltered indoor environments.

Researchers use life-cycle assessment (LCA) as a tool to evaluate the environmental impact of products and technologies across their entire lifetime — from extraction of raw material to end-of-life (disposal or recycling). It is challenging to apply the conventional LCA method to new or emerging technologies, however, due to the sheer quantity of data needed for such studies. This study proposes a screening-to-LCA method that uses available data to systematically evaluate the performance of such technologies, and support the uptake of those that are most environmentally sustainable.

The environmental and economic costs of a selection of common crops have been determined by a new study, which hopes to improve agricultural sustainability assessments in Europe. The researchers used life cycle analysis on organically farmed tomatoes and pears, and intensively farmed wheat, apples, and lettuce to show the overall impact of agricultural methods.

The economic costs of replacing energy inefficient high-pressure mercury (HPM) lamps, used in outdoor lighting, with more efficient alternatives have been explored in a recent study. High-pressure sodium (HPS) lamps would be more cost effective than light-emitting-diode (LED) technology, although the researchers say LEDs could become more economical in the future.

Recent research suggests that increasing the number of private electric vehicles would have very little impact on electricity consumption in Milan, Italy. However, unless there are suitable regulations, the daily demand for power to recharge the vehicles at peak times could overload the capacity of the electric supply system.

Researchers have identified policies in Denmark, Germany and The Netherlands that have made cycling safe, convenient and mainstream in these countries. Coordinated transport, educational and land use measures have increased the popularity of this sustainable mode of transport over recent decades.

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.

Better fuel economy, lower emissions and longer driving ranges are important factors for people considering the purchase of alternatively-powered vehicles (APVs), new research suggests. The German study also found that people would consider paying more for an APV if they could enjoy vehicle tax exemptions, free parking or bus lane access.

What drives people to behave in more environmentally friendly ways? A new study explores factors that affect Dutch motorists’ intentions to switch to electric vehicles. The authors found that they could reliably predict the intention to switch by applying a theoretical framework—Protection Motivation Theory—based on perceptions of the threat of environmental damage.

Public subsidies are important in encouraging organisations to trial and expand electric vehicle fleets, according to new research. The study, based on interviews and reports from 17 organisations, found that the opportunity to test new technology was the most important factor in deciding to trial electric vehicles. However, some smaller independent companies chose not to expand their fleet because of the expense.

The measures available to reduce the noise and vibration produced by trains have been outlined in a recent study. The researchers say the most appropriate mitigation should be determined on a case-by-case basis and life-cycle assessments can help analyse the economic costs and carbon footprint of different methods.

Hybrid and electric vehicles emit lower levels of carbon dioxide and air pollutants than conventional petrol and diesel vehicles, yet their market uptake in the EU remains limited. New research provides an assessment of the Total Cost of Ownership (TCO) — which combines purchase and operating expenses — of different vehicle types. By comparing historical data on hybrid, petrol and diesel vehicles in three countries (Japan, the UK and the USA), researchers found a strong link between TCO and market share of those vehicles. They also identified a number of ways in which policymakers may promote the adoption of cleaner vehicles through the provision of financial incentives.

Electric vehicles (EVs) could play a role in future power supply, but face issues surrounding the longevity of their batteries. This study reconciles two recent contradictory results on the effects of vehicle-to-grid (V2G) technology on battery life-time, and shows that V2G — a process via which EVs would exchange energy with the power grid to provide ancillary services, such as supplying power during peak periods, and helping to regulate grid frequency — could actually extend the lifespan of commercial lithium-ion batteries.

I did not bad mouth my predecessor. However, I never attempted to defend him or any of his actions. I fixed them!

Recycling waste products between companies in industrial recycling networks can bring environmental and competitive benefits. A recent study on whether such networks can be used to advance sustainable development more broadly suggests companies first need a clear, shared network identity before other types of sustainability-oriented cooperation can take place.

As buildings become increasingly energy-efficient in terms of heating and operation, researchers are highlighting the importance of reducing the energy needed to construct the buildings. However, there is a lack of accurate, consistent data, or a standard methodology to properly assess energy requirements at this stage, a new study has found.

Satellite images could be used as evidence in environmental crime cases in the future, a Belgian judge and researcher predicts. However, there are several obstacles to their use at present. Notably, they do not provide sufficiently detailed evidence for the courtroom.

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.

Confusing water bills and complex water tariffs could be making it more difficult for consumers to monitor and manage their own water use, according to a survey of householders on the Portuguese island of Madeira.

The health risks to humans of using recycled water to irrigate crops needs to be carefully managed. New research has demonstrated that ‘managed aquifer recharge’ can be just as effective as conventional water treatments in improving the quality of recycled water for use in irrigation.

Industries, such as paper production, require large amounts of water which can drain vital supplies of fresh drinking water. Researchers working towards the ultimate goal of ‘closing the cycle’ by re-using industrial water onsite have now identified innovative new treatments for wastewater from a paper mill.

Applying a low voltage to polluted river sediment can boost microbes’ natural ability to degrade harmful polychlorinated biphenyl (PCB) contaminants, according to a new study. The approach could be a cost-effective, sustainable strategy to bioremediate polluted sites.

Shellfish harvesting areas in the UK are cleaner, thanks to sewerage improvement schemes over the last decade which have lowered average levels of Escherichia coli in oysters, mussels and other commercially-important species and boosted the shellfish industry’s economic value. Addressing the additional pollution risks from agriculture could further reduce contamination and human health risks.

Investment in cycling initiatives, such as creating new cycle lanes or providing training, can increase the number of people who routinely cycle to work, a new large-scale study in the UK suggests. Town-wide cycling initiatives seemed to be particularly successful when they included workplace measures such as bike lockers, showers and cycle parking.

Ocean-energy technologies — which harvest renewable energy from the sea — will have a significant role to play in a future low-carbon society. A recent life-cycle analysis of different ocean-energy devices has found that life-cycle environmental impacts are caused mainly by the materials used in the mooring, foundations and structures. Improving the efficiency and lifespan of the devices, as well as improving mooring and foundations and deploying devices further out at sea, will help to further reduce the life-cycle environmental impact of ocean-energy systems, according to the study.

Reusing waste water for non-drinking uses in decentralised plumbing networks may improve the efficiency of water supply in urban areas, a new study has found. Modelling this approach in San Francisco, researchers found that, depending on the local geography, a decentralised water supply could lead to energy savings and reductions in greenhouse gas emissions from water treatment of around 30%. Improvements in emerging water-treatment technologies are likely to lead to further savings, which could help increase the efficiency of urban water supply.

Available evidence from the last decade, describing the nature, behaviour and effect of engineered nanoparticles (ENPs) in the environment, has been reviewed. It identified factors that influence ENP distribution and fate and highlighted the existence of significant research gaps which, if filled, would help in understanding the impacts of long-term accumulation of nanomaterials and the changes that occur to them when they are released into the environment.

This study paves the way for better projections of the impact of climate change on plants, including agricultural crops and carbon drawdown. The research shows how an equation used in climate models to represent soil moisture levels is responsible for major variations in estimates of the carbon cycle.
