Charterhouse invested in SLR in 2018, having tracked the business for several years and identifying it as a global pure-play environmental consultancy, with potential to be strategically repositioned to meet the rapidly growing demand for ESG consulting services. Charterhouse has significant experience in the environmental consulting sector through its prior investment in global environmental consultancy ERM, and leveraged its network of industry experts and managers to secure the deal alongside SLR’s management team.
