How Marc is building a better working world

“As we accelerate towards standardized ESG reporting due to market-driven and regulatory developments, the ESG ecosystem to subject to ongoing disruption.

I’m passionate about helping our clients navigate the evolving expectations of stakeholders. My work setting sustainability standards directly helps companies communicate to the capital markets. By bringing my network together, we can advance the conversation between companies, standard-setting bodies, and all stakeholders.

As more companies look to expand corporate reporting and communicate how they plan to reduce their global impacts, I can bring corporate leaders together so we can collaborate on building a fairer and just working world.”
