Who’s Who in Sustainability? Top 50 Influencers to Follow

by | May 23, 2023 | Influencer Lists,

In recent years, sustainability has emerged as a crucial concern for businesses across the globe. With increasing awareness about environmental and social issues, organizations are recognizing the importance of integrating sustainable practices into their operations. This trend is particularly evident in the business-to-business (B2B) sector, where companies are actively seeking sustainable solutions and forging partnerships with like-minded organizations.

Sustainability has become a driving force in the B2B sector, reshaping business practices and influencing decision-making. By embracing circular economy principles, ensuring supply chain transparency, adopting renewable energy and resource efficiency, fostering collaboration, and leveraging digital transformation, B2B organizations can position themselves at the forefront of sustainable innovation. As we move forward, these emerging trends will continue to shape the future of sustainability in B2B, paving the way for a more environmentally and socially responsible business landscape.

Our Who’s Who in Sustainability highlights the top 50 thought leaders and influencers who drove the most engagement across LinkedIn & Twitter over a 6 month period on the topic of Sustainability. Most of these people are industry practitioners and thought leaders who speak at events, write books, articles, and create video and audio content to advance the industry forward.
