Digital noise maps developed under the EU’s Environmental Noise Directive (END) are a useful way of assessing traffic noise exposure for local residents, according to a recent Swedish study. The END maps could also be used to standardise noise exposure information in noise and health research.

Exposure to environmental noise levels above recommended levels results in 1169 cases of dementia, 788 strokes and 542 heart attacks every year in the UK alone, new research suggests. Valuing a year of healthy life at £60 000 (€74 002) means that these health impacts together have a ‘cost’ of £1.09 billion (€1.34 billion), the study’s authors conclude.

Vulnerable groups of people, including those with long-term illnesses, those sensitive to noise or tinnitus (ringing of the ears), people with mental health problems and unborn and newly born babies, are often more susceptible to physical and emotional stresses. As a result, vulnerable groups of people may be more at risk from exposure to environmental noise than healthy adults. However, there is comparatively little research focusing on the adverse health effects of noise on vulnerable people, say scientists reviewing these health impacts.

Physical inactivity raises the risk of ill health, so environmental factors that reduce the level of physical activity in people should be of concern to policymakers as well as to individuals. A new study has associated long-term annoyance with transportation noise with reduced physical activity in Swiss residents, which may indirectly contribute to diseases including cardiovascular disease, diabetes and obesity.

People who are annoyed by environmental noise are also more likely to suffer from depression and anxiety, a new, large-scale study from Germany suggests. The results do not prove that noise causes mental health issues but suggest a possible link, which the study’s authors are exploring further. Of all the types of noise considered in the study, aircraft noise was reported to be the most annoying.

Sustainability in the production of goods and services could be encouraged by replacing value-added tax (VAT) with ‘DaVAT,’ a damage and value-added tax, a new study suggests. This tariff is partly based on a life-cycle assessment (LCA) of goods and services and varies from high (products deemed to seriously harm the environment and human health) to low (those with a lesser impact). The researchers propose a novel way to convert VAT into DaVAT and provide a new policy tool, based on LCA, that can be applied by any country wishing to reform its consumption tax system and move towards a more sustainable future.

A new study has developed a scoring system that could help authorities approve proposals for onshore wind plants. It considered four aspects of a wind farm: the technical properties, the social impact, the environmental impact and the share of earnings offered as compensation for any negative effects.

As wind power becomes more important in the energy mix, so too does the need to manage its variability. A new study has reviewed the options and indicates that, although state-of-the art technologies exist to maximise gains from wind power, they need proper and insightful management.

Climate change will affect the spread and risk of many infectious diseases in Europe, according to a recent survey of leading health experts. The results suggest that more needs to be done to prepare for the expected changes in infectious disease levels, such as improved monitoring of disease.

How does climate change cause extinction? An extensive analysis of the available evidence has explored this question and concluded that climate change’s effects on the interactions between species is likely to be the main reason for local extinctions. For example, climate change may lead to the loss of prey for predators.

Several barriers to upgrading existing social housing with innovative energy systems (IES) have been identified by a study of eight large-scale renovation projects in the Netherlands. These include a lack of trust between stakeholders, opposition from tenants on grounds of increased costs or delays, or poor experience with previous energy projects.

Greenland’s four major glaciers could contribute 19 to 30 mm to sea level rise by 2200, according to a new study. The researchers developed a sophisticated model which provides new insight into the effects of climate change on Greenland’s glaciers, by capturing the complex processes involved in their movement and melt.

Long, unbroken periods of drought can be damaging to the mental health of people living in rural areas, new research suggests. An Australian study found that rural inhabitants who had experienced extensive drought periods over a seven-year period, combined with an unbroken spell for the year before they completed the survey had substantially higher distress scores than other participants.

Ensuring successful public engagement in policy can be difficult. Four key challenges – communicating complexity, providing balanced information, creating space for deliberation and accessing broader values – are highlighted by a new study. Its authors show how they dealt with these challenges in a UK programme, designed to gather public views on the future of national energy policy.

Although low-income households consume less energy than wealthier households, they are still keen to learn how to save energy, for both economic and environmental reasons. This is the conclusion of a recent Swedish study which explored the energy-related behaviour of residents on low incomes. It provides insights which could help inform energy-awareness campaigns targeted at this section of the population.

A number of studies have shown that the public misunderstand global warming. Taking a fresh approach, this study investigated the willingness of the public to take part in activities that mitigate climate change. An international survey of 24 countries revealed that this is strongly related to personal experiences with global warming. The authors say linking actions to benefits could encourage climate change mitigation behaviour.

While extreme environmental events — such as floods and tsunamis — may trigger migrations, the underlying drivers of migration are far more complex and diverse, says new research. The research reviewed the available evidence on population movements associated with extreme weather events and found that people could find themselves ‘trapped’ and vulnerable, whether they stayed at their homes or moved to new locations.

Decision-making about complex environmental problems like desertification, which also have important social and economic implications, could be improved by employing methods outlined in a new study. The study outlines the steps taken by researchers on behalf of the Canary Islands government in devising a policy strategy for tackling desertification and describes a three-step methodology and participatory decision-making process.

Spanish medical and public health researchers have found no clear evidence for increased heavy metal levels in adults living near a recently-built urban solid waste incinerator over two years of operation. Concentrations of lead, chromium and mercury in blood and urine samples taken around the plant were not significantly higher than for populations who lived further away.

A recent study has investigated how taxes on virgin raw materials used in construction, such as gravel and sand, have reduced the use of these resources, based on experiences in Denmark, Sweden and the UK. However, greater incentives to recycle these materials are still needed, says the study.

A new tool to improve the measurement of waste management performance has been presented by a recent study. The researchers applied it to three high consuming cities aspiring to ‘zero waste’, finding San Francisco to be closer to achieving zero waste than Stockholm and Adelaide, due to its emphasis on reusing solid waste.

Plastic debris is a serious environmental concern, as a physical pollutant as well as a chemical pollutant when it breaks down in the marine environment. A new study has now shown that plastics can also concentrate other pollutants, with significantly higher concentrations of toxic pollutants adhering to soft, rubbery plastics, rather than hard, glassy plastics.

Flat screen televisions and computer monitors should be designed so they can be quickly dismantled for recycling, a recent study says. The researchers calculated that in order to ensure the recycling process remains economically viable, it must be possible to disassemble small screens in less than 11 minutes. Good design could lower the costs of recycling and enable near-total recovery of precious metals from the waste screens.

Mussels exposed to high levels of microplastic pollution display signs of stress, new research has shown. However, levels of exposure were higher than found in the wild and no effect on the energy reserves of either mussels or lugworms was observed in the lab. tests. The researchers caution that longer experiments may be needed to reveal microplastics' full effects.

Recycling ships for scrap is a known asbestos exposure hazard, yet this study is one of few to trace asbestos-related cancer rates in shipbreaking workers. The results, obtained from former shipbreakers in Taiwan, show higher rates of cancer overall, especially oesophageal and lung cancers.

A study has evaluated three types of media campaign conducted by a large UK supermarket to encourage shoppers to reduce their food waste. These used social media, an e-newsletter and a print/digital magazine, respectively. Although they all appeared to lead to reductions in food waste to some extent, similar behavioural changes were also seen for customers who had not participated in any of the campaigns.

Urban agriculture is becoming increasingly popular. A recent assessment of rooftop farming in Barcelona shows differing attitudes towards the practice, and provides important recommendations for the development of agricultural policy for the 21st century, such as including food production as a potential use of rooftops in planning legislation.

Sixty-four per cent of organizations in India and Europe invested in cloud technologies in the last two years, followed by IoT, where 51% firms made investments.

In this environment, the delivery of platform-enabled solutions at speed across the entire technology stack becomes even more important, it said. From cloud to networking, data centre to security and more, breadth and depth of capability are essential to recover and restore operations and position organisations strongly for the coming years.

Researchers have shown that graphene paper can be used to construct flexible and rechargeable batteries, which may even perform better than non-flexible batteries. These might be used in a range of portable, bendable and rollable devices and could also help develop new energy generation technology, such as flexible solar cells.

European policies have eliminated the most visible and harmful effects of air pollution, but current rates of emissions still pose a threat to the environment and to human health. A new study has assessed the policy scope to make further environmental improvements by applying the GAINS (Greenhouse gas-Air pollution Interactions and Synergies) model.

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.

Constructed wetlands can effectively remove veterinary drugs from wastewater, preventing contamination of the environment, research suggests. A recent study has demonstrated that laboratory-scale constructed wetlands were able to remove between 94 and 98% of two commonly used antibiotics from pig farm wastewater.

Adding nanoparticles to water in solar collectors, which are used to capture the sun’s energy, can considerably improve their performance, a recent study on nanofluids has found. The energy efficiency of the collector can be increased by up to 76.6% when using water containing 0.1% by volume of titanium dioxide nanoparticles, compared with water alone.

Wind and solar energy are effectively limitless resources, but construction of renewable power must compete for a finite amount of land. This study uses a constrained assessment of available land to see whether global energy demand could be fully met by renewable sources. The analysis predicts that by 2070, the world could produce between 730 and 3700 exajoules of electricity per year (EJ/a1) from renewable power, which, even at lowest available land estimates, could meet 2070 electricity needs in most countries.

Storing atmospheric carbon dioxide (CO2) has the potential to mitigate the impacts of changes in climate. Researchers have now developed a way to inject CO2 into volcanic rock, and tested it in Iceland. Over 95% of the injected CO2 was mineralised (converted into a solid) within two years, instead of taking centuries or millennia as previously anticipated. The technique demonstrates potential for the permanent and safe storage of CO2 within basaltic rocks.

A new study explores how to weigh up the costs and benefits of technologies that extract phosphorus from livestock waste for re-use as fertiliser. Findings from a US case study suggest that recycling phosphorus in this way can cut both water pollution levels and the costs of cleaning up the mineral. However, the technologies’ long-term economic feasibility depends on the yield, quality, and market value of the recovered phosphorus.

The insurance company is planning to make more investments in digital selling and workforce management, thus eyeing the covid-19 situation as an opportunity to strengthen the digital posture than a business challenge.

The rental car service has tweaked its model to support emergency services during the lockdown and is gearing up its IT infrastructure for the post-Covid surge in demand.
