In the period between 1990 and 2003.

The cloture of inefficient plants in the former East Germany is clearly seen in the spreadsheet. However, the matter of emissions is physics. How it came about is not such a big deal. The fact is that it happened. The combined German state reduced coal consumption by 250 MMT in that period, which was not a victory only for the German people, but for humanity as a whole.
Great Britain reduced it's coal consumption by 50 MMT. The chief reason for this was the discovery of natural gas reserves in the North Sea and the expanded use of combined cycle (highly efficient) power plants. (Great Britain this year for the first time in many years has become a net importer of natural gas, and the operating costs of these plants are expected to rise substantially in the next decade.)
France is next on the list, having reduced it's coal consumption by 13 MMT. (France wasn't burning all that much coal in 1990 either, having already replaced most of it's coal burning electricity plants before then - the big reductions in coal consumption came in the 1980's.)
Only Greece (which sells lots of electric power to Italy), Portugal, Turkey increased coal consumption in this period. Italy, Denmark, Norway, and a few other countries remain essentially unchanged in their coal consumption over this period, but they are minor players.)
Some of the coal in the EU has been replaced by natural gas, of course, which is a dirty fuel contributing to global warming, but it is less of a contributor than coal, since modern combined cycle plants are efficient. However the shit is about to hit the fan, in the sense that natural gas prices are climbing rather dramatically.
During the period in 1990-2003, natural gas consumption in Europe has increased by almost 70%. Some of this natural gas, of course, is used for heating and cooking. Conventional thermal generated electricity in Europe increased by 27% while coal consumption was decreasing. This gives an idea about the role of natural gas in European electrical generation. (It also gives an idea about what further reductions are possible - the "path of least resistance," natural gas, is about played out.)
The increase in production of nuclear electricity in Europe kept pace with thermal production, increasing 24% in this period.
