KKR's Global Public Affairs team, an internal team of experts, represents the core of the ESG-related expertise at KKR. The team was formed in 2008 to serve as a resource to KKR, our professionals, and our portfolio companies. The Global Public Affairs team is involved in the due diligence process for all potential private equity investments and also regularly engages with portfolio companies and external stakeholders. Overall, several individuals across KKR have a role in managing ESG issues, including investment team members and KKR's legal and compliance team. Investment Committees oversee ESG issues that are material to an investment and that have been raised to their attention when making an investment decision. Our Portfolio Management Committees and investment professionals have implementation roles with respect to material ESG issues that have been identified in the investment process.
Ken Mehlman (Member), and member of the Global Management Committee, has ultimate responsibility of the Global Public Affairs team and over KKR’s responsible investment efforts. KKR has three full-time professionals dedicated to working on KKR and KKR’s private equity portfolio companies’ sustainability programs. Additional members of the team are responsible for specific ESG opportunities based on their geography or subject matter expertise.
Additionally, in order to better capture value associated with environmental performance management, in 2014, KKR Capstone hired a professional that is 100% focused on environmental resource-related issues with a major focus on energy management. This executive is a Professional Engineer, a Certified Energy Manager, a Certified Building Commissioning Professional, and a LEED Accredited Professional. As of December 31, 2016, KKR Capstone is a team of approximately 60 full-time operating professionals who work exclusively with our investment professionals and portfolio company management teams or our designees. Executives from KKR Capstone play a significant role in managing and supporting KKR's ESG-related programs at KKR portfolio companies, including through the Responsible Sourcing Initiative and the Green Solutions Platform. More information on these programs is available at www.green.kkr.com, www.kkr.com/responsibility/esg-management/partnering-our-portfolio, and www.kkresg.com.
In addition to our internal team and KKR Capstone, we have developed a strong network of external resources, such as non-profit organizations, membership organizations, and thought leaders, to help us manage critical issues, including evolving U.S. and non-U.S. rules governing investment activities generally, environmental and energy policy, labor relations, supply chain management, transparency, and other matters.
