Where are Europe’s Air Pollution Hotspots and How are they being Cleaned Up?

Modelling street level PM10 concentrations across Europe: source apportionment and possible futures (15 page pdf, Kiesewetter, G., Borken-Kleefeld, J., Schöpp, W., Heyes, C., Thunis, P., Bessagnet, B., Terrenoire, E., Fagerli, H., Nyiri, A., and Amann, M., Atmos. Chem. Phys., Feb. 13, 2015)

Also discussed here: Clearing up Europe’s air pollution hotspots (News, International Institute for Applied Systems Analysis, Feb 19, 2015)
Today we review modeling sources of ambient air pollution across Europe down to the street canyon scale (using the GAINS, model developed by the International Institute for Applied Systems Analysis) as measured by 1850 monitoring stations (including 300 traffic stations) and then applying various policy scenarios. Results indicate the while most areas show improvement over the next two decades, some continue to remain below EU air quality limits, specifically, southern Poland, the Czech Republic, Slovakia, northern Italy, and Bulgaria. Adherence to these limits require more than vehicle emission controls such as introduction of low emission zones, improved road materials and road dust removal and eliminating studded tires and controlling emissions from home heating fuels such as wood burning.

A Check List for Managing Urban Air Quality

Growing Public Health Concerns from Poor Urban Air Quality: Strategies for Sustainable Urban Living (9 page pdf, Bhaskar Kura, Suruchi Verma, Elena Ajdari, Amrita Iyer, Computational Water, Energy, and Environmental Engineering, Apr. 2013)

Today we review a paper that zeroes in on the issue of urban air pollution and its health impacts, identifying which pollutants cause the greatest harm and what to do about that in terms of identifying and controlling pollution sources. Given that a million premature deaths and another million pre-native deaths are linked to urban air pollution, along with 2-5% GDP costs for developed and developing countries respectively, much more attention is needed at the municipal level now.

How Will Europe Meet its 2030 Renewable Energy Goal?

Implementing the EU 2030 Climate and Energy Frame-work – a closer look at renewables and opportunities for an Energy Union  (14 page pdf, Anne Held, Mario Ragwitz; Gustav Resch, Lukas Liebmann, Fabio Genoese, Intelligent Energy – Europe, ALTENER, Dec.8, 2014)

Today we review a discussion paper that examines the changes facing the EU in achieving a 27% increase in the share of renewable energies while also reducing greenhouse gas emissions by 40 % before 2030, only 15 years away. Among the factors considered are the declining need for energy efficiencies or at least for financial renumeration as technology improves and matures, the need for states within the EU to consider implementing joint or regional plans to take advantage of and lessen negative impacts of border states.

How Has Germany Improved Its Air Quality?

Clean Air – Made in Germany (50 page pdf, Federal Environment Agency of Germany, Nov. 2014)

Today we review measures undertaken by the national and municipal governments of Germany over the last decade or two to reduce air pollution particularly in its cities and particularly from transportation although initiatives are also in place to deal with wood combustion and ammonia from emissions from agriculture. Specific measures include Low Emission Zones and application of road pricing, restrictions for parking and lower speed limits of 30 kph on major roads. The result is that air quality in German cities today are as high as in rural areas 20 years ago. Future challenges include reducing greenhouse gas emissions to meet EU targets and reducing NO2 and PM emissions from diesel powered vehicles.

What are the Costs and Benefits of Renewable Energy?

The Net Benefits of Low and No-Carbon Electricity Technologies (38 page pdf, Charles R. Frank, Jr., Global Economy and Development Working Paper 73, Brookings Institute, May 2014)

Today we review a research paper that examined the costs and benefits of various non-carbon energy sources, as opposed to oil and gas alternatives, under a number of carbon tax scenarios. Several factors are clear: the benefit of a stable base power or capacity as seen in either natural gas or nuclear outweigh the much lower carbon emissions from solar and wind- to the point that with a $100 per ton carbon tax, nuclear is the favoured option over wind and solar at #4 and #5. If the carbon tax is lower, solar and wind benefits are much much lower than from the other fuel sources. The case for a higher carbon tax is clear if any hope of reducing carbon emissions is to be satisfied.

UK calls for Action to Reduce Air Pollution and Its Health Impacts

Action on Air Quality – HC 212 – Sixth Report of Session 2014–15 (51 page pdf, Environmental Audit Committee, House of Commons, UK, Nov. 26, 2014)

Also discussed here: Air pollution ‘causing deadly public health crisis’ (James Gallagher, Health editor, BBC News, Dec. 7, 2014)

Today we review a report from a Committee of the British House of Commons calling for action both in the short and long term (2030) to improve air quality – its 3rd report on this issue in the last 5 years. In 92% of the Air Quality Management Areas, road transport is the main cause of that pollution, so that recommendations call for more efficient vehicles and fewer diesel powered ones and more Low Emission Zones. The Committee recognizes the powerful lobbies (such as automobile associations and oil/gas industry) against progress – as it is, if not more so in Canada and the USA – but pleads that the UK government should not wait to be ordered by the EU parliament to act.

The Future of the World’s Urban Economy and Carbon Emissions

Cities and the New Climate Economy: The Transformative Role of Global Urban Growth (68 page pdf, Graham Floater and Philipp Rode, New Climate Economy Cities Paper 01. LSE Cities, London School of Economics and Political Science, Jul. 2014)

Today we review a report on the future likely for the globe’s urban areas in terms of growth, their increasing share of the world economy, population and greenhouse gas emissions. A “Three C” model is proposed that shows the advantages of cities adopting compact urban growth, connected infrastructure and coordinated governance that already has shown itself in cities such as Stockholm which has seen a 41% economic increase while reducing carbon emissions by 35% over the last 7 years.
