Environmental targets for sustainable agriculture can usually be met in a variety of ways, but their exact impacts are rarely known. A new study has compared the social, economic and environmental impacts of different policy approaches to hitting conservation targets in Australia, to help regional governments understand the costs, benefits and trade-offs of different policy options.

A recent study has provided support for an alternative means of tackling the unsustainability of resource-intensive economic growth. Using examples of best practice, it upholds a model of moderate growth in GDP combined with a significant increase in the environmental technology market and greater resource-efficiency across all industries.

Renewable energy plays an important role in economic development, according to a recent study which investigated the relationship between economic growth and energy consumption in Europe.

A standardised method to help choose the most cost-effective measures to remediate contaminated sites has been developed by Austrian researchers. The method takes into account a wide range of factors, including the principles of sustainability.

Although most energy in homes is used for heating and hot water, significant amounts of energy are also used when a house is built. A lifecycle assessment of a low-energy, affordable timber house indicates that large energy and carbon savings can be made when alternatives to traditional methods of construction are used.

Assessing the potential of new environmental management tools often brings an ‘innovation dilemma’: is it better to stick with what is known to work, or to implement new measures that are potentially more effective, but also more uncertain? Researchers have proposed an approach to deal with these dilemmas, and applied it to the case study of an invasive species programme in the US.

EU integration may have led to more sustainable consumption patterns in new Member States (NMS) during 1995-2007, according to researchers from Lithuania. Their study indicates that, during this period in new Member States, a smaller share of household expenditure was spent on ‘essential’, but more environmentally-damaging items, such as food, drink and housing, and a larger share on ‘luxurious’, but less environmentally damaging, items.

Informing consumers about their energy use and giving advice on how it can be improved can result in lower public energy consumption, new research suggests. However, if such information campaigns are based solely on monetary savings they are not effective, the study concludes.

A new economic tool designed to encourage sustainable production and consumption has been proposed in a recent study. To ensure that the environmental impact of products is reflected in their cost, the authors of the research recommend a system of green value added tax (VAT) based on life cycle assessment (LCA).

Researchers have developed a new tool to help policymakers access and use data regarding the environmental impacts of consumption and production. Using the EUREAPA tool, decision makers can analyse data from a range of perspectives and create scenarios to understand the implications of changes in consumption and production.

Green taxes could boost economic growth and reduce the 'cash-in-hand' untaxed shadow economy, according to new research. The study modelled green taxes' effects on Spain's economy and suggests the revenue from these taxes would increase economic activity and employment if it was used to reduce income tax.

Congestion schemes can encourage people to adopt environmentally friendly behaviours more generally, a new study suggests. Researchers who surveyed car owners after the introduction of a congestion scheme in Stockholm found that after its introduction nearly half of people surveyed adopted greener behaviours such as conserving energy and water.

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.

Policies and programmes providing technological solutions to improve household energy efficiency alone may be insufficient to actually reduce overall household energy consumption, finds new research. The research examined home renovators’ motivations, behaviours and use of green technologies. Overall, reduced energy consumption was often undermined by other considerations, such as installation and maintenance costs, aesthetic considerations and daily routines or social concerns.

The drive to increase renewable energy production can sometimes be at loggerheads with the desire to preserve natural landscapes. In this study, researchers from across Europe assessed the environmental impacts of renewable energies in the Alps, making key recommendations to resolve conflicts between different users of habitats.

The construction industry is among the top three drivers of resource use in the EU. This study investigated the environmental impacts of a common construction method, drill and blast tunnelling, using life cycle assessment. The researchers assessed 20 years of data on tunnelling in Norway to identify areas that could be targeted to reduce its environmental impact. They recommend reduced consumption of explosives and increased use of renewable energy.

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.

The Alang-Sosiya shipbreaking yards in India highlight the inequalities and opportunities of global waste management. The yards, which recycle retired ships from more economically developed countries, have dramatically altered the ecosystems and social structures of the local area. A study looking at stakeholder perceptions analyses different positions on the social and environmental impacts of the yards.

The uncertain economic climate has severely affected companies’ decisions on whether to renew Eco Management and Audit Scheme (EMAS) certification in Spain, a recent survey indicates. The study suggests that a company is less likely to renew if initial certification was mainly motivated by government subsidies and grants than if certification is believed to improve business performance.

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.

Insights from a recent Italian study could help local authorities across Europe improve their rates of separate waste collection for recycling. The researchers found higher rates of separate waste collection in municipalities with high-quality governmental institutions for waste collection, non-mountainous terrain and higher income levels. Separating household waste into streams, such as glass or food, for re-use and recycling helps free up resources for a circular economy. Good-quality institutions are the main driver of separate waste collection and can overcome barriers such as low economic prosperity.

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.

A recent study highlights the need to consider water consumption when evaluating low-carbon energy production systems, such as biofuels and solar photovoltaic systems, for use in transportation.

Monitors in showers, which display how much water is being used and sound an alarm when a limit is reached, have significantly cut water consumption in household trials. The immediate feedback from the alarm monitor made consumers more aware of their behaviour, which they could then modify.

New research in harbours has explored the most influential environmental and human factors on the release of contaminants from sediment. The scientists suggest that the rate of release can vary considerably between locations and risk assessments of water pollution could be improved if they account for this.

A new review from Romanian researchers has summarised current and emerging methods for cleaning up contaminated land and water. It highlights the need for more consistent testing, reporting and evaluation of different remediation techniques.

A new study suggests shale gas extraction leads to methane contamination of underground water sources and calls for thorough surveys of methane levels at extraction sites. The study presents a timely insight into a relatively under-researched area of science that will help support decisions on the future of shale gas exploration.

A new Spanish study has highlighted current developments in the tourism sector that have significant implications for water supply and demand, but are barely addressed in recent land use policies. The findings indicate that any tourist destination that is to follow the ‘quality tourist’ model will have an increased water demand in domestic residential areas, which is one of the biggest threats to sustainable water management.

Dishwashing is responsible for over half of tap water used in the kitchen, according to the results of a new study, which also suggest that people who live alone consume double the water per person that those that live in a four or five-person household. Although relatively few households were studied, this research could prove useful in helping develop consumer advice for saving water.

Energy production uses large quantities of water and, in turn, water provision requires considerable amounts of energy. A new study has investigated the interconnection between water and energy, the ‘water-energy nexus’, in Spain and found that 5.8% of total electricity consumption is for water-use and 25% of water withdrawals are for energy generation.

The global sea level is rising, yet only part of that rise can be attributed to the effects of climate change. New research has calculated that human impacts on terrestrial water storage make up around 42% of total sea level rise, in particular, the extraction of groundwater that eventually makes its way to the ocean.

A new study has reviewed the dramatic changes that have taken place over recent decades in ‘network-bound systems’ of electricity grids, water supply and wastewater management. Focusing on case studies in The Netherlands, the study found that consumers are becoming more active participants in the supply of these resources and services.

Reservoirs of water stored under the earth’s surface, otherwise known as groundwater, are a valuable resource. However, using a footprinting method, a new global study has indicated that about 1.7 billion people live in areas where groundwater is being used more quickly than it can be replenished.

A new study has shown that agricultural products make the largest contribution to the water footprint of the EU and recommends reducing food waste, changes in diet and increased agricultural efficiencies. On average, each EU citizen consumes 4,815 litres of water per day, when the water used to produce all goods and services, including those imported into the EU, is accounted for.

A recent study suggests that a shift to more sustainable development, based on ecosystem services, is needed to support human health and wellbeing. Focusing on ecosystem services provided by river catchments, this study recommends that more needs to be done on a practical level to support decision-makers, in a way that recognises the relationships between different types of ecosystem services.

Forest management could help adaptation to climate change through its effects on water supply. A long-term US-based study has analysed the impact of forested land use changes on water flow into streams and rivers. It indicated that converting forests from deciduous to pine trees could help water storage in extreme wet conditions, but may be unsuitable in droughts. As such, it recommends tailoring management decisions to the context.

Improving local water quality could mitigate the damaging effects of rising CO2 on marine ecosystems, new research suggests. Scientists in Australia found that nitrogen pollution in seawater, when acting in combination with heightened CO2 concentrations, had a significant effect on the growth of turfing algae, which displace kelp forest ecosystems.

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.

A recent study has revealed how water use has changed across the world over the last 60 years. Growing populations and economic development, particularly in newly-emerging countries, have increased water demand, but technological developments have led to water efficiencies and savings, which moderate these demands.

Research into future climate scenarios suggest that by 2100, climate change could lead to annual damages in the EU from river flooding alone of €14 billion to €21.5 billion, with more people affected than today, and a reduction in household welfare.

A study on how diet can affect water usage in the EU has concluded that a vegetarian diet is the most sustainable, but any reduction in meat consumption would be a move towards more sustainable water use.

Economic valuation of ecosystem services, from good quality water supplies to cooling cities in the face of climate change, can provide vital information for policy decisions. However, the definition and interpretation of ecosystem services need to be clarified to ensure accurate valuations, suggests new research.

Human water consumption has increased the frequency and intensity of periods of abnormally low flow in streams, new research suggests. The frequency of these events increased by 30% globally, largely due to use of water for irrigation, the researchers conclude.

Droughts and floods can significantly damage economic growth, recent research has found. A 1% increase in the area affected by drought can slow a country’s gross domestic product (GDP) growth by 2.7% per year and a 1% increase in the area experiencing extreme rainfall can reduce GDP growth by 1.8%, according to the study. Investments in water security could help reduce this negative economic impact, say the researchers.

Small, artificial wetlands can reduce river pollution by trapping soil and nutrients swept off agricultural land by rainfall, a recent study finds. The researchers recommend that they are used as a back-up option to soil management measures also designed to reduce runoff into rivers.

An average shale gas well in the Marcellus formation will use around 20 000 m³ of freshwater over its life cycle, new research suggests. In total, 65% of this is directly consumed at the well site and 35% is consumed further along the supply chain

Contamination of drinking water in areas close to several fracking sites in the Marcellus and Barnett Shales, USA, is caused by structural problems leading to wells leaking natural gas into aquifers, a new study suggests. The researchers measured trace amounts of chemicals, called noble gases, which formed signatures of the sources of gas contamination in over 130 samples. These findings suggest that, rather than coming from natural sources, such contamination in the area of the investigation is an engineering problem to do with the wells themselves, the researchers say. They stress the importance of ensuring the structural integrity of the wells, which can be done in an affordable manner.

Despite tap water being freely available and safe in many countries, bottled water is widely consumed around the world. This has negative effects on the environment, including water wastage and pollution. This study assessed beliefs about purchasing bottled water and tested three strategies to change behaviour, showing that combining persuasive information and social pressure can create the most positive intentions to reduce consumption.
