Niina Pussinen is co-initiator of the Dutch circular economy platform, CIRCL.NL. This initiative by ABN AMRO Bank supports knowledge sharing and collaborations between business and finance ecosystem players. Real-Estate and the building sector is one of the focus areas. Before CIRCL Niina worked in various lead positions in strategic change and busines management. Sustainability became part of her professional agenda when she was responsible for the development and maintenance of ABN AMRO’s real estate portfolio. Niina introduced the “Right-to-copy”-principle: use own projects as testbeds for sustainable innovation and actively share the knowhow with ABN AMRO’s clients. The efforts resulted e.g. in winning the international BREEAM Award for the ABN AMRO head office and the European Urban Land Institute Award for the CIRCL pavilion. Most importantly the lessons of own initiatives have been shared with hundreds of thousands people worldwide and have sparked up new initiatives and collaborations in the transition to a new carbon neutral circular economy.
