Footprints across Central Europe

Here in the UK, our ecological footprint is 5.6 global hectares per person. That is one of the highest in Europe, requiring around three planets' worth, if everyone were to live in the same way. Below are the footprints of some of the countries of Europe (some of which I hope to visit), all much lower than the UK, as follows:

~ Czech Republic (4.9)
~ Austria (4.7)
~ Switzerland (4.7)
~ Germany (4.4)
~ Netherlands (4.4)
~ Hungary (3.7)
~ Slovenia (3.5)
~ Slovakia (3.4)
~ Croatia (3.0)
~ Bulgaria (3.0)
~ Serbia & Montenegro (2.5)
~ Bosnia Herzogovina (2.2)
~ Macedonia (2.2)
~ Romania (2.1)

I am interested in concrete examples of good practice, methods and lifestyle which we could use as a model, to reduce our own footprint.
