Noise pollution in urban areas can harm our physical and mental wellbeing, and can have damaging effects on urban wildlife. Now, researchers from China have shown for the first time how a ‘land use regression method’ can be used to model urban noise and predict the effects of future planning decisions on noise levels.

Major roads, railways, airports and industrial areas can be a major source of noise nuisance for local communities. To help city planners and architects determine the most appropriate sound insulation design for the exterior of buildings, Turkish researchers have developed a new method that transforms noise maps into insulation maps.

A new study has assessed the annoyance caused by a combination of noises typically found on an industrial site. The results could help improve total noise annoyance prediction models. For example, it was found that ‘broadband’ noises, which consist of a wide range of frequencies, lead to more annoyance if they are combined with a specific additional set of low frequency noises, which can lead to an overall identical noise level.

It is difficult to compare estimates of noise exposure across EU Member States because the methods used to produce the data vary between countries. A new study has investigated five methods of estimating noise exposure and identified some of the reasons for variation in the data they produce.

A recent pan-European study has reviewed the factors which influence how annoyed a person feels about road traffic and aircraft noise. Among its findings, residents in terraced housing or apartments were less annoyed by road traffic noise than residents in semi-detached or detached housing.

Increasing noise levels are a global environmental concern, and have been linked to important health issues, such as heart disease and cognitive development. New Danish research has now shown that it is also associated with an increased risk of diabetes.

Green roofs have the potential to significantly reduce road traffic noise in the urban environment, according to a new study. The results suggest that greening of roofs and walls with materials suitable for growing plants softens the urban environment keeping sound levels low, whereas hard, manmade structures tend to amplify traffic noise.

Ship noise increases shore crabs’ metabolism, a new study suggests. The researchers found that larger crabs were particularly affected by recordings of ship noise in controlled experiments. Increased metabolism is a sign of stress and could potentially reduce the growth of crabs and have implications for their survival, as well as for fisheries.

Researchers in Greece have added a new dimension to noise level mapping by including data on residents’ perception and value of different sounds. This consideration of the experiences of residents in this way could lead to more effective policy implementation.

Companies that adopt the environmental management system ISO 14000, designed to help reduce businesses’ environmental impacts, generally back this up with sincere investment in environmentally-friendly practices, research suggests. Researchers found that adoption of the ISO 14000 was not ‘greenwash’, but reflected a move towards more sustainable practices in both European and North American companies.

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 aircraft noise at night for more than 20 years could increase the risk of heart disease and stroke, according to research conducted around six European airports. Risk also increased for those constantly exposed to road traffic, but this may have been caused by air pollution rather than noise.

Noise from underwater geological surveys may be affecting the feeding and social interactions of harbour porpoises, new research has found. The study, conducted off the north-east coast of Scotland, found that the buzz clicks used by porpoises to hunt and socialise were reduced by 15% during the surveys.

The noise generated by commercial shipping can impair the ability of the critically endangered European eel to avoid predators, new research has found. The results show that marine noise can have serious effects on these animals with potentially fatal consequences.

People living close to road, rail and aircraft noise are likely to experience negative health effects. Long-term noise exposure may lead to problems with their heart and circulatory (cardiovascular) system and night-time noise is particularly disruptive of sleep patterns, which in turn may lead to cardiovascular health problems, a review of research into the effects of noise on cardiovascular diseases has found.

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.

Recent research into the impact of different levels of noise on 75 volunteers reveals that disturbed sleep caused by night-time aircraft noise can damage blood vessels and increase the levels of stress hormones. As these physical changes are potential pathways to high blood pressure, heart and circulatory disease over the long term, reducing night-time aircraft noise is important for preventing cardiovascular disease in people living near airports.

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.

While occupational exposure to noise has declined, ‘social’ exposure in the form of personal music players or rock concerts is estimated to have tripled for young people since the 1980s. A new review examines studies that have investigated noise sources, including environmental (e.g. traffic) and social (e.g. via headphones) sources. The review also explores research into the range of health effects beyond hearing impairments, such as annoyance and cardiovascular problems.

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.

Methods for assessing the sustainability of tourist destinations have been developed. In a new Spanish study, researchers describe a framework for analysing sustainability that is designed for policymakers and tourism managers, and, as a case study, apply it to the region of Andalusia.

A recent study has analysed risks to European renewable industries from the Chinese supply of critical raw materials. The offshore wind sector was found to be the most vulnerable of the renewable industries to supply risks. EU and industry strategies should be able to deal with these supply risks in the short term, but there are potential long-term risks to solar and wind sectors. The development of alternative technologies less reliant on these raw materials, and methods to recycle these materials is, therefore, a priority.

Risk analysis and technology assessment (RATA) involves assessing the possible human, environmental and societal risks of a novel technology at various stages of the development process. However, best practices for RATA’s successful incorporation into large-scale research programmes are still in development. In a recent study, researchers present a case study of their efforts to bring RATA into practice within a large Dutch nanotechnology consortium. By outlining the procedures and products they developed and reflecting on their experiences, the researchers provide valuable insights for the future integration of RATA in technology development projects. The findings are relevant to stakeholders with an interest in supporting the design of key enabling technologies, including governmental agencies and industrial partners.

A new study by European researchers highlights the important contribution of greenhouse gases (GHGs) other than carbon dioxide to climate change and suggests policy measures to help reduce their impact. The study provides improved estimates of the current GHG balance of Europe, taking nitrous oxide and methane into account.

Information policy measures aimed at reducing household energy consumption need to take a number of approaches, according to Swedish researchers. They should stress both economic and environmental motives and encourage public discussion.

Miscanthus grass could have greater potential to mitigate greenhouse gas (GHG) emissions during cultivation than some other biofuel crops, such as switchgrass and corn, according to researchers. The study modelled how carbon and nitrogen circulate through ecosystems on a bioenergy farm, and estimated that miscanthus could provide a net sink of up to 350-428 g of CO2 per m2 per year during this stage of biofuel production.

Continuing economic development and public health measures are likely to outweigh the impact of climate change on malaria prevalence, according to new research. The research found that the prevalence of malaria has declined over the past century despite rising temperatures.

One method that has been proposed for removing carbon dioxide (CO2) from the atmosphere is to ‘fertilise’ the ocean to encourage phytoplankton (algae) blooms. A recent study has outlined the environmental, legal and social implications of large-scale fertilisation of the sea with urea in the Sulu Sea off the coast of the Philippines.

Communication about climate change could benefit from reframing it as a public health issue, according to new research. A health perspective could make climate change more relevant and understandable to the public, whilst information about the health benefits of mitigation policy could provide a positive vision for the future.

New research has predicted that, if current warming continues, an important type of coral in the central Red Sea could stop growing by 2070. Although the same coral has recovered after previous short-term warming events, it appears that the current continuing trend in warming is likely to be more damaging.

Tiny organisms called phytoplankton, which are crucial components of marine ecosystems, have been slowly disappearing over the last century, according to researchers. The decline is worrying because it may have profound effects on marine life, fisheries and carbon cycling. The study suggests the decline in phytoplankton could be linked to climate change.

By 2080, parts of Germany could be susceptible to the spread of malaria for up to six months a year, according to new research. The study mapped areas at risk of an outbreak, considering predicted climate change-driven rise in air temperature and data on the spread of malaria.

Dire messages about the impact of global warming may increase scepticism because they contradict a commonly held belief that the world is a just and orderly place. This is the conclusion of new psychological research which investigated the reaction of individuals to messages about global warming.

New research identifies important influences on the energy and environmental performance of biofuels made from agricultural crops. Type of land use change, type of biofuel crop and the by-products from the conversion process all influence performance.

Although the public are largely aware of climate change, their understanding of how they produce and manage carbon is generally not sufficient to lead to changes in behaviour and lifestyle, according to a recent study. The researchers therefore recommend policy action to increase the ‘carbon capability’ of the general public.

A recent report has summarised what is currently known about the effects of ocean fertilisation as a climate change mitigation measure. The report highlights gaps in scientific understanding of the long term-effects of large-scale ocean fertilisation activities and raises questions about the effectiveness of the approach and the possibility of unintended impacts.

Over a 20-year time period, the greenhouse gas (GHG) footprint of shale gas is greater than that of coal, oil or conventional gas, according to a recent study. Methane emissions make up most of this footprint. This suggests that substituting conventional fossil fuels with shale gas may not have the desired effect to mitigate climate warming in the short-term.

Technological advances in European cement production could reduce energy consumption by up to 10% and CO2 emissions by 4%, according to a new analysis. The research suggests that initial costs of some of the pending technological improvements could be recouped in as little as a year.

New research investigating the effects of naturally occurring iron fertilisation in the sea suggests that large scale geoengineering projects designed to sequester carbon in the deep sea could have a dramatic impact on marine ecosystems. The study found that the organic matter arriving at the sea floor and the species that live there are very different, depending on whether waters are fertilised by iron leached from nearby islands or not.

Rising levels of atmospheric carbon dioxide (CO2) is likely to cause some soils to release large quantities of two potent greenhouse gases (GHGs), nitrous oxide and methane, according to a recent analysis. The results suggest that the contribution of soils and terrestrial ecosystems to slow climate change has been overestimated.

The greenhouse gas emissions from the construction of new houses are so high that they exceed the emissions from three decades of use, a Finnish study has found. The research is based on houses complying with recently introduced, energy efficient building regulations. According to the authors, as buildings become more efficient this ‘carbon spike’ associated with construction is more important than has been suggested by previous studies.

Satellite data from the Torres Islands in the southwest Pacific suggest that rising sea-levels in the region widely attributed to climate change is also partly caused by sinking of the islands following earthquakes in the 1990s, according to recent research.

Permafrost and wetlands in high latitudes could switch from carbon sink to carbon source by the end of the century, according to a recent study. Using a model of terrestrial ecosystems that showed how carbon is stored and released in soils at high latitudes, researchers revealed that climate change could cause these soils to release much more carbon than previously predicted.

The risk of contamination of ground and surface waters and leakage of methane emissions remain key concerns associated with shale gas projects, according to a recent assessment. This is particularly the case if monitoring and regulatory systems are not rigorously enforced. In addition, investment in shale gas could divert resources needed to develop a low-carbon economy, suggest the report’s authors.

A different picture of greenhouse gas (GHG) emissions can be achieved if responsibility for emissions from different economic sectors is placed with the end energy users, according to a new report from the European Environment Agency (EEA). This approach makes sectors such as households responsible for many emissions that would otherwise be attributed to the energy industry.

Scientists’ best estimates of the Energy Return on Investment (EROI) of oil shale suggest it is very inefficient compared to conventional fuel and emits up to 75% more greenhouse gases (GHGs. However, differences in the way energy efficiency is calculated can cause confusion over its potential use, according to the US study.

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.
