About NuStar

Continuing Sustainability Excellence in 2021

During 2021, we continued serving our communities and ensuring they had the reliable fuels needed to power their everyday lives. While the last few years have tested our industry more than any other time in recent history, our excellent sustainability performance demonstrates the strength of our assets and resiliency of our company to meet future energy challenges. 

Company Overview

NuStar Energy L.P. is headquartered in San Antonio, Texas and is one of the largest independent liquids terminal and pipeline operators in the nation, responsibly storing and distributing renewable fuels, ammonia, refined products, crude oil and other liquids. As of December 31, 2021, NuStar had 1,267 employees and operated, primarily in the United States, approximately 9,935 miles of pipeline and 64 terminal and storage facilities with a combined system comprising roughly 57 million barrels of storage capacity.

NuStar’s years of dedication to community, sustainability and resilience is a result of our strong corporate culture, which reflects the vision and leadership of our Chairman, Bill Greehey, and NuStar’s nine Guiding Principles.

Our Guiding Principles are the foundation of everything we do: how we treat each other, the environment, our communities, our customers and business partners. As a result of our strong culture and our Guiding Principles, NuStar has received numerous awards including being named to FORTUNE Magazine’s “100 Best Companies to Work For” list 12 times, FORTUNE Magazine’s “Best Workplaces for Millennials” list five times and Latino Leader Magazine’s “Best Companies for Latinos to Work” list two times. We have also been awarded the International Liquid Terminals Association’s (ILTA) Safety Excellence Award 12 times. Our commitment to making a difference not only ensures that NuStar continues to provide our communities with safe, reliable and affordable access to fuels, but also ensures that we continue to support our employees and build value for our investors. While we are proud of those honors and awards, we are even prouder of the work we do every day: safely and reliably supplying the energy that fuels modern life, contributing to our communities in the markets we serve and building value for our unitholders.

Service to Our Communities

To power modern life, our communities need to stay connected to reliable, convenient and high energy density fuels. We are proud to be a company that safely transports and stores liquid fuels, including fossil fuels and lower carbon intensity renewable fuels, in an environmentally responsible way to meet those needs. These high energy density liquid fuels are used in the vehicles that get us where we need to go, whether that is commuting to work, shopping for groceries, taking our children to school or flying on an airplane to visit family and friends. The liquid fuels that we transport and store also provide the energy our society depends on to reliably power everything from the trucks and airplanes that deliver goods and products, the generators people rely on in emergencies and essential services vehicles used by our first responders and military. Whether for powering rescue vehicles for first responders to save lives, transporting us to and from our daily errands or delivering food and packages quickly, our society depends on liquid fuels, and NuStar is proud to have been connecting people with that energy, safely and sustainably, for more than 20 years.

In addition to storing and transporting the liquid fuels that power urban communities, we are proud to serve America’s farmers and rural areas where the reliability and convenience of these fuels can be even more important. NuStar plays a vital role in helping to ensure America’s food supply — from fueling for tractors, to supplying the ammonia America’s farmers use to fertilize their fields and increase crop yields, to fueling the trucks that transport food from the farm to your table, NuStar plays an integral part in bringing affordable, healthy foods to our communities, throughout the Midwest and across the country. In addition, we look forward to developing future partnerships to supply ‘green’ and ‘blue’ ammonia, for existing applications and for exciting future opportunities, like renewable electricity generation and safe, efficient transportation of hydrogen to power fuel-cell vehicles.[1]

We are also proud of our contributions to America’s economic well-being and energy independence, and we plan to continue to provide our communities with the reliable liquid fuels they need for decades to come, safely and responsibly, so our communities can continue to be secure and thrive.

[1]“Blue” ammonia is produced with natural gas, but the associated emissions are captured and stored. “Green” ammonia is produced using “renewable” electricity to power an electrolyser to extract hydrogen from water and an air separation unit to extract nitrogen from air, which are then combined, through a chemical reaction powered by renewable electricity, to produce ammonia.

Our Continuing Tradition of Sustainability

We are committed to maintaining our 20-plus-year record of sustainability excellence, and we are proud to publish this Sustainability Report, updating our inaugural report.

In 2019, we formed an ESG Task Force to focus on sustainability reporting and build upon our best practices. In 2020, we created our Sustainability Working Committee to enhance our sustainability disclosures. This committee includes representatives from Environmental, Safety, Human Resources, Corporate Communications, Investor Relations, Legal, Operations, Accounting, Business Development, Internal Audit and other departments. In 2021, we promoted our commitment to ESG excellence in alignment with our strategic goals, and we also launched our Sustainability webpage. 

This Sustainability Report continues to highlight our performance and is informed by guidance from the Energy Infrastructure Council (EIC) and the Sustainability Accounting Standards Board (SASB). Unless otherwise noted, all information, data and metrics in this report reflect our worldwide operations as of December 31, 2021 and include any divested assets through the date of divestment.
