Figure 4 also shows large differences between the two emissions categories in many prefectures, indicating the importance of investigating carbon footprints at the sub-national level.
The public health problem of traffic is amplified as one considers that in 2001 a large proportion of the vehicles were in the high emissions categories (EURO 0 and EURO 1) and that 17.4% of them were diesel-powered vehicles.
65, this one works selected industries or emission categories (lead particles, in the case of battery makers).
This chapter applies the physical, chemical, and biological mechanisms described in the previous chapter to controlling and preventing air pollution from actual sources in various emission categories.
In general, singular approaches for estimating individual emission categories have been proposed [24, 115] and only one approach has been outlined for dealing with the uncertainties of using different spatial units for the full life cycle assessment [69].
Therefore it's no wonder that within the derivation of generic emission categories (environmental release categories, ERC) the question of where to draw the boundary leads to controversial discussions between industry (wants very specific stipulations) and ECHA (wants "use" to be understood more broadly) [23].
In Germany, the so-called ETB guideline (ETB = Committee on Harmonized Prescriptions for Construction) was created in 1981 and classified particle board into three emission categories, E1−E3.
Whereas ocean transport (JD318) and coal products (JD139) have similar global GHG intensities to JD153 and JD166, these derive mainly from emission categories (D) and (F).
For most sectors, it is clearly the contributions of emission categories (S) and (F) that push global GHG intensity values upward, but the magnitude of these contributions varies among sectors.
The sector numbers and corresponding sector names and global GHG intensities as well as figures for the emission categories (D), (S), and (F) are listed in Table A2 of the Supporting Information.
