| Zusammenfassung |
| During the last twenty-five years European emission data have been compiled
and reported under the Cooperative Programme for Monitoring and Evaluation
of the Long-range Transmission of Air Pollutants in Europe (EMEP) as part of
the work under the UNECE Convention on Long-range Transboundary Air
Pollution (LRTAP). This paper presents emission trends of SO2 reported
to EMEP and validated within the programme for the period 1980–2004. These
European anthropogenic sulphur emissions have been steadily decreasing over
the last twenty-five years, amounting from about 55 Tg SO2 in 1980 to
15 Tg SO2 in 2004. The uncertainty in sulphur emission estimates for
individual countries and years are documented to range between 3% and
25%. The relative contribution of European emissions to global
anthropogenic sulphur emissions has been halved during this period. Based on
annual emission reports from European countries, three emission reduction
regimes have been identified. The period 1980–1989 is characterized by low
annual emission reductions (below 5% reduction per year and 20% for
the whole period) and is dominated by emission reductions in Western Europe.
The period 1990–1999 is characterised by high annual emission reductions (up
to 11% reduction per year and 54% for the whole period), most
pronounced in Central and Eastern Europe. The annual emission reductions in
the period 2000–2004 are medium to low (below 6% reduction per year and
17% for the whole period) and reflect the unified Europe, with equally
large reductions in both East and West. The sulphur emission reduction has
been largest in the sector Combustion in energy and transformation industries,
but substantial decreases are also seen in the
Non-industrial combustion plants together with the sectors Industrial combustion and
Industrial production processes. The majority of European countries have
reduced their emissions by more than 60% between 1990 and 2004, and one
quarter have already achieved sulphur emission reductions higher than
80%. At European level, the total sulphur target for 2010 set in the
Gothenburg Protocol (16 Tg) has apparently already been met by 2004.
However, still half of the Parties to the Gothenburg Protocol have to reduce
further their sulphur emissions in order to attain their individual country
total emission targets for 2010. It is also noteworthy that, contrasting the
Gothenburg Protocol requirements, a growing number of countries have
recently been reporting increasing sulphur emissions, while others report
only minor further decreases. The emission trends presented here are
supported by different studies of air concentrations and depositions carried
out within and outside the framework of the LRTAP Convention. |
