An influx of pollution from Asia in the western United States and more frequent heat waves in the eastern U.S. are responsible for the persistence of smog in these regions over the past quarter century despite laws curtailing the emission of smog-forming chemicals from automobile tailpipes and factories.

The news about the Environmental Protection Agency’s plan to limit carbon pollution from existing power plants just got even better: the proposed Clean Power Plan (CPP) can save the power industry and its customers — us — as much as $2 to $4 billion in 2020 and $6 to 9 billion in 2030, while cleaning our air and modernizing the electricity sector.

The Brazilian government is seeking to award contracts in an auction tomorrow for natural gas- and coal-fueled power plants, reversing a drive that previously favored renewable-energy projects. It would lead to the first new thermal plants in three years, after the government scaled back such projects and awarded wind contracts starting in 2009 and solar energy earlier this year.

Beijing, where pollution averaged more than twice China’s national standard last year, will close the last of its four major coal-fired power plants next year.

Air pollution is costing advanced economies plus China and India an estimated USD 3.5 trillion a year in premature deaths and ill health and the costs will rise without government action to limit vehicle emissions, a new OECD report says.

Today’s post, marking World Environment Day, is from OECD Secretary-General Angel Gurría. Air pollution has become the biggest environmental cause of premature death, overtaking poor sanitation and a lack of clean drinking water.

Taxes are potentially among the most effective ways of cutting pollution and greenhouse gas emissions, but they are currently – with very few exceptions – underused; and even where used, they are frequently designed in a sub-optimal way.

The current Volkswagen diesel emissions scandal highlights the difficult reality of making the transition to a low-carbon economy. It also highlights the growing need for governments to make smart policies, based on actual costs.

Outdoor air pollution is a major determinant of health worldwide. The objective of this paper is to inform the development of improved estimates of the social costs of human morbidity impacts resulting from outdoor air pollution in two components; namely to develop a core set of pollutant-health end-points to be covered when estimating the costs of morbidity, and to review current estimates of the cost of morbidity from air pollution.

Outdoor air pollution could cause 6 to 9 million premature deaths a year by 2060 and cost 1% of global GDP – around USD 2.6 trillion annually – as a result of sick days, medical bills and reduced agricultural output, unless action is taken, according to a new OECD report.

Anyone else feeling exhausted by all this drum humming about air pollution? Indeed it appears the fumes won’t be dissipating any time soon as we consider the extent to which tyre and brake rubbish exacerbate the problem.

New evidence on the effect of energy prices on outward FDI can provide some reassurance in light of concerns about Pollution Havens.

This paper presents updated results for the cost of ambient air pollution in 41 countries: the 6 major emerging economies known as the BRIICS – Brazil, Russia, India, Indonesia, China and South Africa – and the 35 OECD member countries.

Air pollution in Delhi has been so bad this November that the Indian Medical Association declared a public health emergency. According to the latest Global Burden of Disease study published in The Lancet, outdoor air pollution caused more than a million premature deaths in India in 2016, whose cost, according to OECD estimates, amounts to more than USD 800 billion.

Populations of otters, grey seals and sea eagles are slowly recovering in Sweden, which is likely to be thanks in part to a ban on organochlorine chemicals, such as PCBs and DDT, in the 1970s, according to a new study. However, the research shows that negative effects of these chemicals on the reproductive health of female animals persisted for more than 15 years after the ban was introduced.

A recent study has assessed the costs and effectiveness of reducing phosphorus pollution for lakes in Scotland, UK, to achieve good ecological status as required by the EU???s Water Framework Directive (WFD). It was found that phosphorus in 72% of the lake area in Scotland could be mitigated at a cost of ??5.7 million (???7 million) per year, which is considered a proportionate or reasonable cost given the resulting social benefits.

To date, it has been difficult to collect data that are robust enough to demonstrate specific effects of chemical pollution in rivers on aquatic wildlife. However, a recent study combining detailed chemical, toxicological and ecological data in three European river basins now provides evidence linking cause and effect by revealing significant differences in the effects of differently polluted sediments on the organisms living in the river basins and the riverbed biodiversity.

Levels of air pollution significantly increase on the island of Svalbard in the Norwegian Arctic when tourist cruise ships are present, according to a recent study. With shipping levels rising in the region, the researchers recommend that stricter emissions regulations are introduced in order to limit the impact of pollution on the Arctic environment.

Researchers have developed a new model to assess the health-related external costs arising from air pollution from ten major emission sectors. Applying the model at national and Europe-wide levels, they suggested that the major contributors to costs were industrial power production, agriculture, road traffic and domestic combustion.

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.

A pan-European survey has revealed the public’s awareness, concerns and priorities about human impacts on the oceans. The results show high levels of concern about marine pollution in particular, and that, generally, respondents were most concerned about the issues they felt most informed about. The study could help policymakers develop marine strategies that are more responsive to public preferences, its authors say.

Underground water aquifers are a significant source of drinking water. In a recent study, French researchers found that pesticides applied to crops can take many years to sink down through the ground and reach groundwater. This means that they may still be entering aquifers, even after agricultural application has stopped.

Phosphorus is a major pollutant of surface waters, contributing to poor water quality. A recent study investigated best management practices to reduce the over-application of phosphorus and minimise phosphorus losses from agriculture in four regions across Europe and North America.

Widespread use of antibiotics to prevent and treat infections in people and animals as well as for promoting growth in livestock is causing environmental contamination. A new study highlights the need for extra measures to reduce environmental pollution from antibiotics. Such pollution can increase the risk of diseases caused by bacteria that become resistant to antibiotics.

The damaging health impacts of some key air pollutants can occur at lower atmospheric concentrations than indicated by the most recent World Health Organization (WHO) Air Quality guidelines, set in 2005 and currently used in Europe. This is according to a new WHO report, which assesses scientific evidence to help inform European air pollution policies.

A target level of 20 micrograms of phosphorus per litre of lake water could help keep many lakes safe for recreation by restricting the growth of harmful algal blooms, European research suggests. The scientists analysed the relationship between phosphorus levels in medium- and high-alkalinity lakes, the growth of cyanobacteria blooms and the concentrations of cyanobacteria that trigger World Health Organization (WHO) warnings.

People exposed to fine particle (PM2.5) and ozone pollution are at increased risk of suffering out-of-hospital cardiac arrests, according to a recent Finnish study. Cardiac arrest is more likely within 24 hours after exposure to PM2.5 and up to several days after exposure to ozone.
