Who We Are

Solutions for Success

Kedge Environmental & Social Impact Consulting, LLC was founded in 2014 as a social enterprise with a single mission: to leverage environmental clients in the global north to support environmental leaders & innovators in the global south. 


Though we’ve grown since our founding, we’re still the same at heart: we use our networks and expertise to accelerate the impact of environmental conservation efforts across North America & Europe, then leverage those outcomes into support for environmental projects in East & Southern Africa.
