For estimating the national heavy metal emissions for the BAU and MFTR scenario by a bottom-up approach, it is necessary to assume which measures are implemented for the emission sources and based on this to estimate there emission factors. For the sake of completeness, these assumptions are listed here not only for the two future scenarios considered in ESPREME but also for the two 2020 scenarios that will be assessed in the succession project DROPS.

Sector	BAU 2010	BAU 2020	MFTR 2010	MFTR 2020
Large combustion plants	Dedusting: fabric filters and electrostatic precipitators operated in combination with FGD	Activated carbon filters Sulphur-impregnated adsorbents Selenium impregnated filters	Like BAU 2020	Integrated gasification combined cycle (IGCC) Supercritical polyvalent technologies In 2020 50% participation in electricity generation by thermal method
Iron and steel production	In sintering: fine wet scrubbing systems or fabric filters with addition of lignite coke powder In blast furnaces: scrubbers or wet ESPs for BF gas treatment In basic oxygen furnace: dry ESPs or scrubbing for primary dedusting and fabric filters or ESPs for secondary dedusting In electric arc furnaces: fabric filters	In sintering: catalytic oxidation	BAU 2010 and 2020 techniques in existing installations Sorting of scrap	New iron-making techniques Direct reduction and smelting reduction
Cement industry	Dedusting: fabric filters and electrostatic precipitators	-	Like BAU 2020	All plants with techniques for heavy metals reduction To 2010 activity decrease by 7% To 2020 activity decrease by 29% (DEG)
Agriculture	-		80% reduction of sewage sludge applications on agricultural areas 80% reduction of the use of basic slag for liming 80% reduced amounts of heavy metals in the forage of cattle, pigs, poultry, sheep and goats 80% reduced amount of nitrogen application to fields in countries outside the EU
Chlor-alkali industry	Phase-out of mercury cell plants by 2010
Road transport	Phase-out of leaded petrol in all countries except Russia, Belarus and Serbia-Montenegro (Directive 2003/17/EC for EU-countries)
