Consulting for Planet & People

SUMA Net Impact (SUMANI) is partnering with YPE NYC, Comrie Enterprise, BlocPower, RSTR Media & Strategy LLC, and Kinetic Communities Consulting for its biannual panel event! Join us for a discussion that highlights the multifaceted world of sustainability consulting. This semester’s theme is “Consulting for Planet and People – Environmental Justice for all” and the panel will showcase prominent consultants who have successfully managed projects that have combated the negative effects of climate change, bettered the lives of BIPOC groups suffering from numerous injustices, and stimulated economic growth. We will get to hear their unique experiences and learn their distinctive tactics to best mitigate environmental issues, uplift marginalized communities, and still make a significant return on investment. We want to show new and veteran consultants that it is time to holistically consider the triple bottom line and consider the net impact of our work on all stakeholders, not just shareholders.
