The efforts to raise awareness on this topic go back to a paper we published in 2005 on the added value created by environmentally friendly property.

In addition to the expertise-based real estate business foundation, the Bank has worked to orient its businesses toward promoting environmentally friendly property through pioneering initiatives in environmental real estate.
