Since their peak around thirty years ago, emissions of air pollutants in Europe have come down significantly. Tougher emission standards for industry and road vehicles have resulted in less polluting power plants and cars. In addition, stricter environmental legislation has helped to speed up structural changes in the energy and transport sector and improved energy efficiency.

While the air we breathe has become cleaner, it is still unhealthy or even deadly. Current levels of air pollution are responsible for more than 400,000 premature deaths in the EU every year, as well as allergies and respiratory and cardiovascular diseases which result in extra medication, hospitalisations and millions of lost working days.

These health impacts carry enormous costs to society. In the year 2010 alone, health damage in the EU from air pollution was estimated to amount to between €330 and €940 billion. This means that even a pure economic cost-benefit approach motivates a significant stepping up of action to tackle air pollution, since the health benefits alone outweigh by far the additional costs for emissions control.

For example, the monetized health benefits of the Commission’s recent proposal for a new national emissions ceilings (NEC) directive are up to 42 times greater than the estimated emission abatement costs.

Moreover, it is not only people that suffer. Air pollution also damages nature and biodiversity, with the deposition of acidifying and eutrophying pollutants and the concentrations of ground-level ozone still exceeding the tolerance limits of sensitive ecosystems over millions of hectares in Europe.

Clean air and water, healthy forests and heathlands, and a rich flora and fauna are necessary for a high quality of life, and must not be overlooked by policy makers just because they are difficult to value in monetary terms.

The gravity of the current air pollution situation calls for an EU air quality strategy that establishes a very high level of ambition. It is certainly not acceptable that even after 2030 air pollution will still cause a quarter of a million of premature deaths among EU citizens, and that millions of hectares of valuable ecosystems will still be exposed to pollutant levels in excess of their critical loads, as would be the case under the ambition level of the Commission’s proposed new NEC directive.

Applying new and improved emission control techniques must be part of the solution, but minimising the use of fossil fuels is key to resolving both climate change and air pollution, as it cuts emissions of the main greenhouse gas carbon dioxide as well as those of health-damaging sulphur dioxide, nitrogen oxides, fine particulate matter and mercury.

Improvements in energy efficiency, increased use of less- or non-polluting renewable sources of energy and behavioural change (e.g. reducing car usage and meat consumption) are examples of measures that will benefit both air quality and the climate.

Going for tougher climate and energy targets will help to achieve air quality targets, and the significant short-term co-benefits for health and nature from the resulting air pollution reductions should also help to motivate a much higher level of ambition for climate policy.

Air pollution still harms ecosystems

While acidification has been greatly reduced since its peak in 1980, emissions of nitrogen-containing air pollutants continue to damage more than half of sensitive ecosystems.

Since their peak around thirty years ago, emissions of air pollutants in Europe have come down significantly. Tougher emission standards for industry and road vehicles have resulted in less polluting power plants and cars.

Continued succes for renewables

Denmark got 41 per cent of its power from the wind in the first six months of 2014.  Renewables are advancing all over Europe.

Saving Turkey from coal

Turkey should stop the construction of new coal- and lignite-fired power stations and start phasing out the existing ones, says Greenpeace Mediterranean.

A fair share of climate responsibility

Annex 1 countries need to have negative emissions of 441 GtCO2 by 2050, according to a new equity proposal from several Latin American countries. 

Lignite power provides bargain-priced pollution

Combustion of lignite is one of the environmentally worst ways to generate energy. Even so, there is a continued increase in many parts of Europe.

Proposal for coal phase-out in Germany

BUND, a German environmental organisation, suggests a legally binding law to close all coal power stations by 2030.

Emissions are falling – but not enough

While emissions of acidifying sulphur pollutants in the EU have come down by 84 per cent since 1990, those of nitrogen compounds have fallen only by 41 per cent.

UK brought to court on bad air quality

New figures from the UK government show air quality in some of the country’s biggest cities will not meet European Union pollution limits until after 2030, twenty years after the original deadline.

Sustainable food choices

Excluding meat from our diet is not enough on its own to benefit the climate. Eating a lot of cheese or simply eating a lot of everything also leads to high greenhouse gas emissions.

New figures on global ship emissions

In 2012 worldwide shipping consumed some 300 million tonnes of fuel oil, resulting in emissions of 949 million tonnes of carbon dioxide. Unless concerted action is taken, these emissions are expected to grow by up to five times by 2050.

US to cut CO2 from existing power plants

By 2030, the CPP proposal should reduce CO2 emissions from the power sector by 30 per cent nationwide, compared to 2005 levels, and provide up to US$93 billion in climate and public health benefits

Carbon dioxide concentration surges

The concentration of carbon dioxide in the atmosphere increased last year at the fastest rate for nearly 30 years, according to the latest data from the WMO.

EU’s Dirty thirty

The thirty most CO2-polluting power plants in Europe also cause 20 per cent of the health costs of the sector.

High diesel NOx emissions prevail

A study by Dutch consultancy TNO has found that in spite of facing a tighter NOx emissions limit of 80 mg/km, diesel-driven Euro 6 vehicles emitted around 500 mg/km in real-world driving circumstances, which means they are approximately equal to Euro 4 and Euro 5 vehicles.

Cracks found close to Norwegian CCS operation

An EU-funded project called ECO2 has investigated the influence of CO2 seeping from the Norweigan CCS project by the Sleipner gas field in the North Sea.

Norway invests in Dutch CCS

The Norwegian government cancelled its national CCS project in Mongstad in 2013 because of spiralling cost estimates for setting up a full-scale CCS plant. Instead, it will invest 14 million euro in a CCS demonstration project in Rotterdam in the Netherlands.

Vattenfall to co-operate on Canadian CCS

Vattenfall has stopped its CCS research in Europe, including Schwarze Pumpe CCS. The company has instead taken some first steps to cooperate with SASK Power in Canada and its Boundary Dam Power Station CCS project. 

Beijing shuts down big coal-fired power plant

Beijing has closed the first of four large coal-fired power plants set to be decommissioned as part of the city’s efforts to cut smog-forming air pollution. Beijing’s three remaining coal-fired power plants are all to be closed by the end of 2016.
