Protest votes: why will some people not tell how much they are willing to pay for clean air?

What is the value of clean air? Answering such a question may be achieved by asking citizens how much they are willing to pay. However, some individuals give 'protest vote' responses to such questions. Recent research in EU countries found that the main reasons for this were because they felt that the polluters themselves or the government should be responsible for such costs.

Regional air pollution improvements have global health benefits

Reductions in emissions of fine particle air pollution can prevent premature deaths, not just locally, but also in countries thousands of kilometres away, new research illustrates. The transcontinental study examines the effects of reducing air pollution emitted from Europe, North America, South and East Asia by 20% and shows that, for example, reductions in the EU would mean 3700 fewer premature deaths in the other three regions every year.

Waters acidified by air pollution have recovered as predicted

Back in 1999, a group of scientists predicted how changing air pollution levels would affect the acidity of lakes and rivers in Europe in 2010 using a computer model. A follow up study has now gathered actual measurements of these waters to see if the predictions came true. The observations show that most of the rivers and lakes did recover from acidification, as forecast by the model, and demonstrate the model’s value in predicting future water chemistry, the authors say.

Methane: satellite data may improve emissions estimates

Greenhouse gas (GHG) inventories are significantly underestimating methane emissions from a region in the southwest of the United States, and potentially elsewhere, a new study has found. The authors of the study suggest that satellite data could be used to identify and quantify new sources of methane, such as fracking.

Two for the price of one: climate change mitigation measures also reduce air pollution

Effective greenhouse gas (GHG) mitigation measures to stabilise global temperature change to no more than 2°C above pre-industrial temperatures would also substantially reduce air pollutant emissions, recent research predicts. A variety of mitigation options are available, including switching from fossil fuels to renewable sources of energy. To achieve the necessary GHG emission reductions, one key option is to impose carbon taxes. However, these would need to be high to help achieve this target, according to the study’s authors.

Air pollution modelling could help predict algal blooms

Models that predict how nitrogen from the air is deposited in the sea could be useful in predicting algal blooms. Based on the knowledge that excess nitrogen increases algal growth rates, researchers simulated nitrogen deposition in the North Sea and suggested that, using predicted weather data, it might be possible to adapt this approach to predict algal blooms.

Long-term exposure to aircraft emissions causes premature death

As well as contributing to the greenhouse effect, aircraft emissions have an important impact on air quality and human health. This study, which quantified the effect of civil aviation emissions across the globe, suggests they could be responsible for 16 000 premature deaths every year, at an annual cost of over €18 billion. The air quality costs of aviation were similar to its climate costs, and over 10 times larger than accident and noise costs.

Emissions from 2008–2015 VW diesel vehicles fitted with ‘defeat devices’ linked to 59 premature deaths

In September 2015, the United States Environmental Protection Agency (EPA) alleged that Volkswagen (VW) violated the US Clean Air Act by fitting ‘defeat devices’ in their light-duty diesel vehicles to falsify the results of emissions tests. According to a study assessing the potential impact of this decision, an extra 59 early deaths in the US are likely to be caused by exposure to PM2.5 and ozone.

Air quality assessment in the EU: room for improvement?

Different modelling approaches are used to design and assess air quality plans across Europe. This study assessed the strengths and weaknesses of these different approaches.

They identify integrating local-scale and large-scale models and verifying models with measurements as the most important challenges.

Nitrification inhibitors — climate change mitigation tool recommended by the IPCC – may be less effective than previously thought

Nitrification inhibitors are thought to mitigate climate change by reducing emissions of nitrous oxide — a potent greenhouse gas — from land. However, they may not be as effective as once thought, a new study suggests. The researchers found that, while inhibitors decrease emissions of nitrous oxide, they can increase emissions of ammonia — which is later converted to nitrous oxide. They recommend these effects are considered when evaluating inhibitors as a mitigation technology.

Precautionary Principle: decision-making under uncertainty – September 2017

One of the greatest challenges facing today’s environmental policymakers is how to deal with complex risks, such as those associated with climate change. These risks are difficult to deal with because they are not precisely calculable in advance. Where there is scientific uncertainty about the full extent of possible harms but ‘doing nothing’ is also risky, decision-makers may use the precautionary principle. This Future Brief explores the role of the precautionary principle in EU law and policy, and examines key points of discussion drawn from the evidence.

‘Cooling-off effect’ causes public perception of novel environmental technology to improve over time

Researchers have published a paper providing evidence that a ‘cooling-off effect’ can lead to increased public acceptance of new environmental technologies over time. The scientists analysed survey results from over 1 000 respondents in Germany, using solar radiation management (SRM), a controversial climate-engineering technique, as a test case. They found that, following a cooling-off period of either one month, 12 months, or 18 months, acceptance of SRM increased significantly — and that the longer the cooling-off period, the larger the increase. These findings have far-reaching implications, both for the deployment of SRM and for climate policymakers seeking to more accurately measure the public acceptability of novel interventions.

New energy-positive waste-water treatment process uses just 15% of the energy required for current alternative

Conventional municipal waste-water treatment processes are based on aeration, which is energy intensive. Now, researchers have developed an alternative waste-water treatment process. In addition to avoiding the use of aeration in favour of filtration/biofiltration and encapsulated denitrification (the application of capsules containing nitrifiers, which convert ammonium into nitrate), the process also uses waste biosolids to generate electrical energy. The process has been tested in a pilot facility and found to require just 15% of the energy required for conventional approaches. Moreover, the process is energy positive, as the biosolids are able to generate more than enough energy to power the treatment plant. If this technology could be scaled up to the municipal level, it could significantly reduce the energy use and environmental impacts of waste-water treatment.

How can ‘omics’ technologies – which enable large-scale, speedy biological data analysis – improve environmental risk assessment and management?

High-throughput ‘omics’ technologies, which allow exact and synchronised study of thousands of DNA, RNA, proteins and other molecules, are rapidly becoming more advanced and affordable. As these technologies develop, it is becoming quicker, easier and more affordable to generate unprecedented amounts of biological data, much of which could usefully inform environmental management. So far, however, the application of omics information in environmental management has failed to keep pace with the rapid development of omics-based research, meaning there is untapped potential. A recent study highlights the value of bringing omics information into environmental management and outlines practical ways in which omics can contribute to the risk assessment and management of chemicals.
