It all depends on the local waste management. In most of western Europe, plastic is either recycled or burned in a waste management facility to recycle energy.
The impact of plastic bottles is probably lower than for alternatives like glass. Glass is heavier and causes more CO2 emissions because of the increased energy use for transporting them.
