Pete Trelenberg has experience in the world’s largest publicly traded energy company, Exxon Mobil, through assignments in Texas, New Jersey, California, and Hong Kong. Today, he advises Exxon Mobil leaders on the company’s response to environmental issues, sustainability, and regulatory reform.
Trelenberg joined the company at the Bayway Chemical Plant in Linden, New Jersey, in 1980, shortly after earning his UW-Madison bachelor’s degree in civil and environmental engineering. While at Bayway, and then at Exxon Chemical’s headquarters in Houston, Pete served in a variety of roles in plant operations and maintenance, planning, project management, marketing and business analysis. From 1997 to 2001, he and his family lived in Hong Kong and Trelenberg served as the company’s Asia oxo alcohol business director. His success in building up Exxon Chemical’s presence in the fast-growing China market ranks among his proudest accomplishments.
After returning to the United States, Trelenberg was transferred to Torrance, California, where, as refinery manager, he focused on improving operations performance, strengthening underlying management processes, and upgrading facilities at the Torrance Refinery. During nearly four years at Torrance, Trelenberg was instrumental in establishing programs to improve safety, reliability, environmental compliance, and profitability.
Prior to assuming his current position, Pete was ExxonMobil Chemical Company’s planning and business development manager, where he was responsible for long range strategic planning, annual planning and budgeting, and mergers and acquisitions for one of the world’s largest chemical companies.
In 2011, Trelenberg became Exxon Mobil Corporation’s manager for environmental policy and planning, where he advises senior management and the board of directors on climate change, and manages greenhouse gas, sustainability, and regulatory reform policy for the corporation.
Trelenberg’s many fond memories of his time at UW-Madison include the Badger men’s hockey team winning the 1977 NCAA championship; Friday afternoons on the Terrace; Saturday football games; canoeing on Lake Mendota; and running along the lakeshore. Living in Madison also gave him the chance to spend time with relatives who lived in Merrill and Janesville. He has maintained his UW-Madison connections through Exxon’s recruiting efforts, and through his participation on the civil and environmental engineering visiting committee.
Trelenberg lives in Dallas with his wife, Susan. The two frequently visit their children, Leigh Anna, Peter Jr., and Erik, who reside in southern California, and Trelenberg enjoys cycling, fishing, upland bird hunting, and hiking. He enjoyed coaching youth sports when his children were younger, and remains an avid Badger sports fan.
