2.B.10.b - Storage, Handling and Transport of Chemical Products

Emissions from storage consider all refinery products. According to the EMEP guidebook, fuel-related emissions are reported under 1.B.2. (see Chapter 3., 1.B.2a Oil ). Emissions from other mineral oil products that are not used as fuel (like naphtha, methanol etc.) are reported separately here.

A distinction of mineral oil products is only made between fuels and naphtha. Based on the individual annual amount for these two subcategories, a split factor is calculated.

The annual production of naphtha through the time series is listed in Table 1 below.

The emission factor used for NMVOC was determined by evaluating emission declarations from refineries for the period 2004 through 2016, in the framework of a research project (Bender & von Müller, 2019)¹⁾. Since no data was available for earlier years, the data obtained this way was used for all years as of 1990.

No recalculations have been carried out compared to last year's submission.

An ongoing research project estimates emissions from storage and cleaning of tanks for oil and oil products - results are planned to be implemented into the inventory in 2025/26.
