By John Engel, Chairman, President and Chief Executive Office, Wesco International.

I am pleased to present Wesco’s 2025 Sustainability Report, which demonstrates our commitment to furthering sustainability, innovation and connection in a rapidly changing world. This report highlights how we continue to build a brighter future for our customers, supplier partners and the communities we serve.

In 2024, we continued to focus on execution while furthering our vision to become the best tech-enabled supply chain solutions company in the world. Our digital transformation is well underway. We’re more than halfway complete on our technology and capabilities build which, once deployed, will help us to do our jobs better, deliver new products and services for our customers and create added value for our supplier partners.

Our progress was driven by strong employee engagement, evidenced by our Wesco Listens survey results which showed improvements in trust and safety, surpassing industry and global benchmarks. These metrics reflect our commitment to operational excellence and our dedication to creating a trusted and safe workplace for all.

Wesco’s global capabilities, leading scale and expanded portfolio of services and solutions uniquely position us to address the world’s critical infrastructure needs, including enhanced power generation, electrical grid modernization, automation, connectivity, security, and supply chain resiliency. I am incredibly proud of our talented Wesco team, whose hard work and dedication drive our success.

This year, we saw momentum in four key areas:

Environmental Stewardship:

We continued to pursue our sustainability goals with progress towards achieving our 2030 carbon reduction target. Our focus on renewable energy exhibits our dedication to reducing our environmental impacts.

Empowering Our People and Communities:

We believe that investing in our employees is crucial for our continued success and growth. In 2024, our employees collectively spent over 172,000 hours in training and development. This commitment to training not only enhances the skills and capabilities of our workforce but also fosters a culture of innovation and inclusiveness. We launched the Wesco Cares Scholarship Program to support the next generation of tradespeople and fortify our commitment to the electrical industry. The $200,000 in scholarships has been awarded to qualified and deserving students pursuing careers in specialized fields within the U.S. electrical industry.

Our Wesco team worked especially hard to help our communities in times of need and I am grateful for their dedication to our customers, supplier partners and one another. In addition to responding to storms and other natural disasters, together we made a positive impact through our Wesco Cares program. Wesco team members volunteered more than 3,000 hours of their time in 2024. We expanded our partnership with Habitat for Humanity, contributing to projects such as Home Equals and construction of sustainable homes in Chiapas, Mexico, along with support of the 2024 Jimmy & Rosalynn Carter Work Project in St. Paul, Minnesota. We joined The Red Cross’s Annual Disaster Giving Program to help them mobilize and respond to emergencies big and small at a moment’s notice.

Ethics and Governance:

Integrity remains at the core of Wesco’s operations. Our robust global compliance program continues to promote the highest ethical standards. We remain steadfast in our commitment to transparency and accountability.

Innovation for a Greener Tomorrow:

We offer a wide range of sustainable products and services that help our customers reach their own sustainability goals. From energy-efficiency and energy-management solutions to renewable energy, we are dedicated to environmental responsibility.

Wesco has developed programs, services and solutions that are designed to be scalable and adaptable, enabling us to meet the evolving needs of the industries we serve. This includes supporting residential, commercial and utility-scale solar projects through supply chain solutions, a broad product portfolio, and expertise that adapts to consumer demands. Innovation remains a cornerstone of our success. We continue to expand our portfolio of sustainable solutions, providing customers with tools to achieve their own environmental goals.

Sustainability is a journey. As we look to 2025 and beyond, I am confident that the dedication of our teams, partners and stakeholders will continue to drive progress. From advancing renewable energy solutions to supporting our employees and communities, we remain steadfast in our vision for a better future for all.

Thank you for being part of this journey.

  an international organization that helps companies and cities measure and disclose important environmental impact information through an annual questionnaire and rating system.
