Climate change in Germany
The Rhineland is historically a heavily industrial and population-dense area which includes the states of North Rhine-Westphalia, Rhineland Palatinate, and Saarland. This region is rich in iron and coal deposits and supports one of Europe's largest coal industries. In the past, sulfuric acid emissions from Rhineland coal plants contributed to acid rain, damaging forests in other regions like Hesse, Thuringia, and Saxony.
