The economic impact of reducing food waste in Germany, Poland and Spain

A third of all food produced for human consumption is lost or wasted, and the EU alone wastes an estimated 88 billion tonnes of food every single year. This is equivalent to 76 kilograms per person per year. This is an unsustainable level of waste which threatens food supply and the environment. The EU is taking several actions against food waste, as a critical part of efforts to achieve a circular economy, where resources are used more sustainably.

Europe makes tentative progress in reducing transport’s environmental impact

A new report indicates that some progress has been made towards meeting key sustainable transport targets, but challenges remain. Improvements in passenger vehicle efficiency has led to reductions in emissions, however, reductions in oil consumption are not sufficient to meet targets, with more policy initiatives and continued monitoring needed to ensure that sustainability goals are achieved.

Ocean acidification reduces fishes' ability to respond to sound

Researchers have found that ocean acidification leads to changes in the ways that clownfish normally respond to sound. As many species rely on hearing for orientation, habitat selection, avoiding predators and communication, ocean acidification could compromise auditory behaviour crucial for survival.

Long-term exposure to railway noise linked to reduced cognitive performance

Residents living near a busy railway line in Strasbourg were found by researchers to have reduced cognitive function compared to residents in quieter areas, which may be the result of long-term exposure to night-time noise. Psychological tests suggested that they had not adapted to the noise over the years, and they did not become less affected with time.

New tool to assess sustainability of transport noise reduction devices

A new method of assessing the sustainability of noise reduction devices (NRDs) used in transport infrastructure, such as noise barriers or absorptive claddings, is presented in a recent study. The new set of specially designed sustainability criteria allows NRDs to be easily and accurately evaluated, its developers suggest.

A vegetarian diet can help reduce water consumption across Europe

Different European regions have very different diets and environmental conditions, meaning their water consumption varies widely. Despite this, switching to vegetarian diets in keeping with regional variation would substantially reduce water consumption in all areas, a new study concludes. Where people choose to eat meat, adopting a healthy diet low in oils and sugar will also reduce water consumption, although to a lesser degree.

Energy-efficient cooperative housing reduces bills for residents

Relatively simple, low-cost measures, such as insulating walls and installing solar collectors and efficient heaters for hot water can significantly reduce energy consumption in housing developments, according to a recent study from Portugal.

Tools to reduce resource consumption identified by analysis of historical resource efficiency

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.

Warming boosts plant growth, but reduces species diversity

Wetland biodiversity may fall under climate change, a new study suggests. The researchers' experiments indicated that, overall, plant growth in wetlands will be boosted, but a small number of plant species well suited to the warmer conditions will out compete other species. However, climate change's effects on biodiversity may be less severe if plants are able to move to cooler locations, towards the poles.

Shale gas: independent planning is key to reducing environmental impacts of fracking

Funding for scientists, planners and inspectors should be available before any shale gas development begins, a new review recommends. As revenue for such staff is often provided by the development itself, planning, which is vital to provide immediate environmental protection as well as monitoring long-term impacts, is neglected. The researchers also advocate the use of 'adaptive management' as a decision-making framework for this complex issue.

Persuading the public to reduce bottled water consumption

Despite tap water being freely available and safe in many countries, bottled water is widely consumed around the world.

Holistic approach needed to reduce consumption of lightweight plastic carrier bags

Reducing plastic carrier bag consumption in different EU Member States requires different approaches and combinations of measures, according to a new study. The authors studied consumption and littering levels across Europe in relation to national plastic bag consumption reduction policy options, and found that there is not one specific solution for both of these factors, nor a single solution that can be used in all Member States. They suggest a holistic approach and additional research into consumer or stakeholder behaviour is needed.

Good water quality improvements in the River Seine – but more needs to be done to reduce nitrate pollution

Water policies at European and French national levels have led to a clear improvement in the water quality of the River Seine, a new study has found. A significant reduction in phosphate and ammonium pollution and increasing oxygen concentrations are evident. However, nitrate concentrations are still higher than the recommended level for good freshwater status, despite substantial reductions of surplus nitrogen in agricultural soils over the past few decades. The researchers recommend strengthening current agri-environmental management measures to help the river to return to a fully healthy status.

Volume of leachate and environmental impact from landfills reduced — but legacy effects remain

Landfill leachate is the liquid that seeps through or out of waste deposits in landfill sites. EU regulations, such as the Landfill Directive1, have significantly reduced the volume of leachate produced, a study on leachate management in Ireland has found. Leachate, mainly from younger landfills in Ireland is, however, stronger since implementation of the legislation, and the researchers say the future treatment of leachate under stricter environmental protection regulations will continue to be a long-term concern for landfill operators and regulators.

Decentralised supply of recycled water may save energy and reduce greenhouse gas emissions

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.

Food waste: a reduction of up to 50% could reduce EU household expenditure and environmental impact

As the global population increases, it is increasingly urgent that policymakers and other actors facilitate feasible, sustainable solutions to the issue of food waste. This study explored the market effects of reducing household food waste within the EU. The researchers found that reductions of up to 50% by 2030 would lead to household cost savings, a shrinking agri-food sector, a mild negative macroeconomic impact and desirable reductions in environmental pressures, such as greenhouse gas emissions, land use and water abstraction.

Soil biodiversity reduces nitrogen pollution and improves crops’ nutrient uptake

Increased soil biodiversity can reduce nitrogen pollution, improve nutrient uptake by plants and even increase crop yields, new research suggests.
