The „Rhine Action Programme“ introduced by the ICPR in 1987 as a comprehensive restoration programme was the most important predecessor of “Rhine 2040” and “Rhine 2020”. A year earlier, the Rhine had been poisoned by a catastrophic chemical spill, killing fish and small animals over a distance of more than 400 km from Basel to Koblenz and severely polluting the Rhine water as far as the Netherlands.
In 2000, the "Rhine Action Programme" came to an end. The balance shows that, largely, it achieved or surpassed its objectives:
