The Top 25 Sustainability Consultants and Leaders of 2022

The Consulting Report is pleased to announce The Top 25 Sustainability Consultants and Leaders of 2022. Sustainability has become an important concern in corporate boardrooms across all industries, but many companies have struggled to actually implement successful changes and meet their ESG (environmental, social, and governance) goals. Meanwhile, pressure has been mounting on companies from stakeholders of all types—from customers to investors to employees—to show that they not only care about protecting the environment, but that they are making a concerted effort to become more environmentally friendly. The leaders on this year’s list are the keys that unlock the sustainability potential of these companies and add incredible value for their clients.

Dr. Velislava Ivanova, Americas Chief Sustainability Officer for EY, leads a team of more than 500 professionals in the EY Americas Climate Change and Sustainability Services practice. Clint Follette, Managing Director and Senior Partner at BCG, leads BCG’s climate and sustainability work globally in oil, gas, and chemicals and advises while advising leading companies on topics like decarbonization, plastic waste, and renewable fuels and materials. And Sasha Duchnowski, Partner at Bain & Company, leads Bain’s global Food System Transformation efforts and has led or advised on critical programs and collaborations like Pacific Island Tuna and the Alliance to End Plastic Waste.

This year’s awardees hold a variety of positions and work across many different industries, but they all are indispensable to their clients for the same reason: they are the catalysts companies need to get their ESG effort in order, whether that means getting it off the ground or accelerating it to net-zero and beyond. In so doing, they offer their clients the ability to outstrip their competition and increase profits while protecting the environment. Please join us in recognizing The Top 25 Sustainability Consultants and Leaders of 2022.
