parncutt I am writing on behalf of a Graz NGO called Rettet die Mur (save the river Mur).

The City of Graz plans to fell about 10,000 (ten thousand) trees along the river Mur in October 2017 to enable construction of a disputed sewage/rainwater storage pipe. Further information:

In the past decade, the European Union has repeatedly warned the City of Graz about particulate matter pollution levels. Graz is surrounded by hills so there is relatively little wind. Although some progress has been made, felling 10,000 trees near the city centre is likely to cause particulate pollution levels to increase.

Is it possible for the EEA or another European institution to intervene on this basis?

RuiweiChen Hello, I have 3 questions concerning the report EMEP/EEA air pollutant emission inventory guidebook - 2013, part 1.A.3.b.i - iv.
(1) For the cold-start quotient for calculating the cold-start emissions of road transport, in the table 3-46 on page 64, part 3.4.3.2, this coefficient is less than 1 for VOC if the temperature is higher than 24°C, or for PM if the temperature is higher than 22°C. In these cases, perhaps the cold emissions are less than the hot ones for theses two pollutants, but with the equation (10) in page 42 to calculate the corresponding cold emissions, the results would be negative. Would there be a different formula to calculate the cold emissions for these cases?
(2) Still for the cold emissions, the beta reduction factors are available for post-Euro 1 gasoline vehicles till Euro 4, in table 3-44 on page 63. Is there factors for post-Euro 5 vehicles? Same question for diesel light commercial vehicles of table 3-63, on page 74.
(3) For calculating the cold emissions for post-Euro 1 light commercial vehicles (gasoline or diesel), the part 3.4.3.8 (last paragraph) and 3.4.8.9 (page 73) indicate using the equation (32) on page 66, in which the hot emission is based on Euro-4 vehicles, while the parameter tables recommended are for Euro 2 -- Euro 4 vehicles (table 3-44 for gasoline light commercial vehicles, and table 3-63 for diesel ones). I am wandering if we could use the equation (29) on page 63 instead.
 
Thank you in advance for your kind answers.
