The lifetime environmental impacts of non-electrical consumer products, such as clothes, could be cut by over 40% if consumers maintained them in a more environmentally friendly manner, new research suggests. The study found the impacts of eco-designed products fell significantly when user guidelines were included in the eco-design.

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.

Biofuels have a role in future energy production. However, the way in which they are produced and managed can determine if they benefit society, the economy and the environment, concludes a recent report on the sustainable production and use of biofuels.

A new analysis of greenhouse gas (GHG) emissions from Swiss household consumption reveals a large difference between the best and worst households – which range between the equivalent of 5 to 17 tons of CO2 per capita per year. It suggests GHG reductions are possible if more households adopt similar consumption patterns to those with the lowest emissions.

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.

Maintaining and restoring the world's drylands or arid zones could provide a win-win option for addressing climate change, according to new research. Drylands not only store large amounts of carbon, but improving how they are managed could reduce the vulnerability of ecosystems and humans.

The thinning of Iceland’s ice caps could be influencing volcanic activity, according to new research. The study developed a model to predict the changes in pressure on magma caused by thinning ice and applied it to the recent activity of two Icelandic volcanoes. The results suggest that the effects of thinning ice may increase volcanic activity in some cases, but reduce it in others.

New research undertaken in Greece has demonstrated that although 90 per cent of people believe climate change is related to fossil fuel consumption, only half think that biofuels could be an effective solution. The findings have important policy implications for the public acceptance of biofuels.

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.

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.

A Belgian public survey on greener energy consumption has found that positive messages about environmental issues may be more effective than negative messages in encouraging behavioural change for large sections of the public. The researchers suggest this can help policy planners devise targeted communications strategies.

The impact of climate change on electricity consumption is important to both adaptation and mitigation policies. New research has estimated that over the next 100 years climate change could cause up to a 20 per cent decrease in demand for electricity for heating in Northern Europe and up to a 20 per cent increase in demand for electricity for cooling in Southern Europe.

Recent research from China suggests that partially converting both natural gas and coal into 'syngas' fuel for power generation can generate around 6 per cent more electricity than competing 'conventional' gasification methods. The savings arise from more efficient use of the chemical energy in gas and coal which is lost in a conventional burner.

Land cleared in the tropics loses nearly twice as much carbon and produces less than half the annual crop yield as land in temperate zones, according to researchers. Their analysis of the trade-off between crop production and the loss of carbon stored in vegetation highlights the need to target reforestation in the tropics.

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.

Vehicle fuel economy has markedly improved, but there are other factors that influence fuel consumption and transport emissions, according to new research on the EU, USA and Japan. Changes in vehicle size and power also play a role indicating that, if fuel prices do not keep rising, policy focus may need to shift to managing vehicle use.

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.

A new report on biofuels by the UK’s Nuffield Council on Bioethics has produced a set of five ethical principles to guide the development of biofuels technology and policy. It recommends applying these principles to create comprehensive standards to ensure that biofuels address, rather than exacerbate, global problems.

A potential method for reducing greenhouse gas (GHG) emissions associated with extracting energy from oil shale has been highlighted by a recent study. A ‘self-fuelling’ method that recycles waste gas could cut GHGs emissions by 50% compared to the conventional oil shale product and 70% compared to crude oil.

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.

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.

A new survey from 2010 reveals that upfront costs of up to €14,000 and lengthy payback times can discourage even the most environmentally conscious citizens from installing domestic renewable technology, such as solar panels and wind generators. However, people signing up to a ‘climate pledging’ scheme were still at least 11 times more likely to install these technologies than the average person in the UK.

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.

The majority of respondents to a UK survey would like to see labels explaining the carbon footprint of the food they buy. 72% of the supermarket shoppers questioned were in favour of carbon labels on food. The survey also found that 42% had changed their shopping habits in the last 10 years in response to environmental concerns.

Concerns about the negative impacts of ‘sunshade’ geoengineering on global food security are not supported by a recent modelling study, the first to simulate yield changes in a geoengineered climate. However, to mitigate climate change, the researchers suggest actions to reduce CO2 emissions are safer than introducing geoengineering projects, partly because some regions may actually suffer reduced crop yield in a geoengineered climate.

Turning brown seaweed into biofuels is one option that has been proposed to help meet the world's growing energy demands from renewable sources. Recent research has overcome a major barrier to converting the majority of sugars in seaweed into bioethanol and other valuable products by using genetically engineered bacteria to break down the seaweed.

A new study has explored how cities can create a low carbon future by presenting an approach to stakeholder engagement that develops scenarios of an ideal city. Rather than projecting towards a low carbon target for the future, the study suggests that ‘backcasting’ to the present day from these scenarios may provide a useful goal-orientated approach to environmental planning in cities.

Residents living within half a mile of unconventional natural gas wells may have an increased risk of illness from exposure to air pollution from the wells, according to a recent study. The peer-reviewed study recommends that risk prevention efforts to minimise impacts on human health should concentrate on communities living and working close to wells during well completions and that further studies on health effects of exposures to air emissions from such projects should be carried out.

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.

A recent study has explored how national regulations and culture, company size and experience with weather incidents have influenced adaptation to climate change in electricity distribution companies in Norway and Sweden. Smaller companies in a strongly regulated environment, with less experience of extreme weather events, find it more difficult to pursue climate change adaption results,

Techniques for reducing the noise caused by wind turbines are reviewed in a new study. Noise pollution is one drawback of wind power and restricts where wind farms can be located in relation to people and wildlife. The researchers identify methods that could aid the design of low-noise wind turbines, including modifying the blade’s shape and adding rows of brushes to the edge of the blade.

Grasses growing at the bottom of our oceans lock away large quantities of ‘blue carbon’, according to a new study. The results suggest that the soil that seagrass grows on is capable of storing more carbon than soils on land and as a result of the current global decline in seagrass, vast stores of carbon may be being released into the ocean and atmosphere.

A free online system for assessing the sustainability of buildings is due to be launched across Europe in July this year. The tool captures scientific complexity whilst being accessible and easy-to-use, its developers say.

Green spaces in cities can have a cooling influence which helps reduce the ‘urban heat island effect’. New research from Portugal has demonstrated that even a small community garden can provide a significant cooling impact that can help efforts to adapt to climate change.

Climate change is a particular threat to island nations and effective adaptation is vital. A new analysis examines current adaptation measures in tropical Oceania and identifies guidelines for implementing resilient, ecosystem-based adaptation (EbA). Among its recommendations, local communities should be fully involved in planning adaptation measures.

Coastal wetlands can substantially reduce erosion, property damage and human deaths in the face of rising sea levels and severe storms, recent research concludes. Understanding whether wetlands can provide effective coastal protection is essential to developing effective climate change adaptation strategies.

Conserving salt marshes helps protect our coasts, according to research which shows that they stabilise shorelines and protect them from damage by incoming waves. Their benefits are particularly significant in light of the destruction caused by storms and flooding, which are likely to increase under climate change.

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.

Climate change may increase the risk of outbreaks of infectious diseases, such as salmonella or tick-borne encephalitis. A new study has outlined five main steps in assessing policies to ensure that they can respond effectively to this challenge and highlights the importance of involving stakeholders at every stage of policy assessment.

Research from the US helps paint a clearer picture of the extent of global sea level rise, by considering new satellite data on the Earth’s gravity. Its findings support reports of accelerating ice melt and suggest that most of the change in sea levels is caused by receding polar ice sheets and mountain glaciers.

The world’s ocean ecosystems will suffer warming, increased acidity, low oxygen and reduced primary food supply as a result of rising CO2 and this is likely to have dramatic environmental and social impacts, a new study concludes. It predicts that the most vulnerable low-income countries, where 870 million people are dependent on marine ecosystems, would be affected if CO2 emissions are not tackled.

A measure of ‘chemical footprint’ is being developed by researchers to assess the environmental impacts of the toxic chemicals released by the production and consumption of goods. The methodology, based on life cycle and risk assessment, is also designed to be linked to the resilience of ecosystems to chemical exposure.

A community-level initiative in the UK has successfully used social marketing techniques to encourage participants to reduce their greenhouse gas emissions. On average, participants reduced their emissions footprint by 2 tonnes every year. Based on the initiative, the authors of this study propose a framework to guide future community engagement.

Over 75 000 regulatory inspection reports for over 32 000 oil and gas production wells drilled in Pennsylvania, US between 2000 and 2012, have been analysed in a recent study. In these reports, the inspectors logged six times as many incidents of damage to the walls of shale gas and oil wells than in wells for conventional oil and gas.

Rising levels of atmospheric CO2 will increase the severity of wheat diseases, reducing yields and threatening food security, a new study suggests. Researchers found that levels of two common wheat diseases increased significantly when plants were grown with elevated CO2. Furthermore, disease levels were even worse when the plants and pathogens had been acclimatised to the higher concentrations of CO2 beforehand.
