Fortune 500 companies now collectively represent $41 trillion in revenue, over a third of the global GDP, and employ 70 million people worldwide.¹

As the climate crisis intensifies, these large corporations are setting ambitious net-zero targets and creating ripple effects across their vast supply chains. Nearly half of Fortune 500 companies now plan to reach net zero by 2050, up dramatically from just 8% in 2020.²

In this webinar, GM’s Chief Sustainability Officer, Kristen Siemen, and Greenplaces CEO, Alex Lassiter, shared strategies and insights for mid-market suppliers on how to navigate evolving standards, protect key accounts, and transform compliance into a competitive advantage.

Key takeaways

  • Start small to build momentum. Kristen shared how GM’s early push for renewable energy enabled them to surpass their initial 2050 goal, achieving 100% renewable energy in the U.S. by 2025. Taking the first step is often the hardest but yields the most significant results.

  • Supplier collaboration is critical. GM’s Supplier Sustainability Council and supplier pledge demonstrated how partnerships across the supply chain drive alignment with ambitious carbon-neutral goals.

  • Sustainability is a business resilience strategy. Beyond compliance, embracing sustainability reduces risk, increases efficiency, and strengthens customer relationships. As Kristen said, “It’s just good business.”
