When Ceska Sporitelna, one of the Czech Republic’s leading banks and a subsidiary of Austria’s Erste Bank, decided to dip its toe into the world of sustainable banking, it decided to devote half of its environmental banking resources to renewable energy projects and the other half to ecologically sound infrastructure projects.

But over the past four years, it has become obvious that there is much more interest in renewable energy like wind farms than in so-called green buildings, says Jan Herman, leader of sustainable banking product development at Ceska Sporitelna.
