KKR completed the investment in GreenCollar, an environmental markets platform. Financial terms were not disclosed. "This acquisition is both a culmination of part of the development of our long term strategy and the beginning of the new phase of our growth with a virtually limitless horizon. KKR has already brought dynamism and capacity to exciting sustainability initiatives planned but not implemented until we found the right partner," Lewis Tyndall, GreenCollar Co-Founder and Non-Executive Director.
