O U R S U S T A I N A B I L I T Y C O M M I T M E N T Brad Barron President & Chief Executive Officer, NuStar Energy L.P. Doing the right thing for the right reasons is deeply ingrained in NuStar’s culture of responsibility, caring and sharing and has been since NuStar was established 20 years ago. In fact, long before ESG became a common term, one of the things that made NuStar such a great place to work was our strong corporate culture, which was created by our Chairman, Bill Greehey. In our culture, we treat everyone with respect, we give back to our communities, we protect the environment, and we demand that all of our employees hold themselves and each other to the highest ethical standards. We are proud of our record of responsible operations, and we are committed to maintaining excellence and continuing to take care of one another and our planet. We are also proud of the resilience and strength our business has shown, across economic cycles and our footprint. We are focused on nurturing that resilience and strength to ensure NuStar continues to prosper as the Nation’s and the World’s growing energy needs evolve, and we are already demonstrating our ability to do just that through the success of our West Coast renewable fuels logistics network, which both generates solid returns for our investors and helps lower carbon emissions in communities across the region. We are also focused on continuing to do the right thing, across our operations, every day of every week: to protect the environment, our communities and our employees, to ensure safe, reliable energy service to our customers and to build value for our investors. R e s p o n s i b l y R e s i l i e n t 5 We are Committed to Maintaining Excellence and Taking Care of Each Other and Our Planet, now and in the Future
