Cummins Scores 100 In First Year on Climate Disclosure Leadership Index

Cummins transparency and openness about climate change impact and progress earned it top marks.

CDP LogoCummins has joined companies like Boeing, Apple, Google and Microsoft on the CDP’s Climate Disclosure Leadership Index in 2015.

The company was identified as a U.S. leader for the quality of climate change related information that it has disclosed to investors and the global marketplace through CDP, the international not-for-profit working to promote sustainable economies. The CDP was formerly known as the Carbon Disclosure Project.

The CDP’s S&P Climate Disclosure Leadership Index (CDLI) was released in late 2015 in the S&P edition of CDP’s annual global climate change report.

Cummins earned its position on the index by disclosing high quality carbon emissions and energy data. In its 2015 filing with CDP, the company for the first time estimated that the collective emissions of the just more than one million engines Cummins and its joint venture partners sold in 2014 would be 914 million metric tons of carbon dioxide (CO2) over their useful lives of 10, 20, or even 40 years.

CO2 is a key contributor to global warming and the primary greenhouse gas emitted through human activities, according to the U.S. Environmental Protection Agency (EPA). Improving fuel efficiency results in an almost equal reduction in CO2.

The data reported by Cummins has been independently assessed against CDP’s scoring methodology and is marked out of a top score Climof 100. Cummins scored 100. Those organizations graded within the top 10 percent of the companies participating in the CDP constitute the CDLI.

Cummins has disclosed its greenhouse gas inventory and emissions through Carbon Disclosure since 2006. The company’s Action Committee for Environmental Sustainability has said the company’s biggest opportunity to reduce its CO2 footprint is through the fuel efficiency of current and future products, both in their design and use.

"At Cummins, we are dedicated to fostering a cleaner, healthier and safer environment..." - Jennifer Rumsey, Cummins Vice President and Chief Technical officer

The company has launched an aggressive effort to work with its customers to improve fuel efficiency in addition to its initiatives to design for the environment while providing customers with the power they need to succeed.

Jennifer-Rumsey“At Cummins, we are dedicated to fostering a cleaner, healthier and safer environment and we know our stakeholders value this commitment,” said Jennifer Rumsey, Cummins’ Vice President and Chief Technical Officer. “Our customers and their businesses trust our leadership in technology and innovation and depend on us to be the experts in enabling environmental sustainability. Our investors and other stakeholders value this transparency and accountability.”

The CDP says top scores indicate a high level of transparency in the disclosure of climate change-related information, providing investors with a level of comfort to assess corporate accountability and preparedness for changing market demands and emissions regulation.

Cummins officials today (Sept. 18, 2018) dedicated a state-of-the-art integration center designed to test the integration of company products and concepts into customer trucks and other equipment.

The new Cummins Machine Integration Center in Columbus, Indiana (USA), is capable of testing a variety of powertrains, including electrified power, and represents another significant step in the company’s efforts to enhance innovation across a broad portfolio of power options.

“This facility is already a key tool in our toolbox as we work to provide turn-key machine integration solutions for our global customers,” said Jennifer Rumsey, Vice President and Chief Technical Officer at Cummins. “In addition, we can showcase our global integration technology leadership and provide an enhanced workspace for our employees who will have new opportunities to develop their skills and capabilities.”

The new center replaces a crowded facility in Columbus that was retrofitted for the same kind of work. The new center is larger, with room for 60 to 70 trucks on the site, and includes 16 dedicated service bays, a fabrication shop, an instrumentation lab, a parts inventory and a powertrain integration area. Everything is laid out for the greatest possible efficiency, including making it easier to pick up materials for recycling.

The center is perfectly aligned with the company’s goal of offering customers a range of dependable power solutions, including clean diesel, natural gas, and hybrid and fully electric powertrains. It has a dedicated space just for electrification work, with limited access to ensure only those with the appropriate safety training can enter.

The new building also has office space for about 45 employees and plenty of collaborative working space for visiting employees from nearby Cummins facilities who might have business at the center. Finally, the new center has room for expansion as critical technologies are identified and incorporated into Cummins products.

Dedication of Cummins Machine Integration Center
A crowd of elected officials, the media and Cummins employees attended today's dedication and toured the facility.


A lot of the center’s work will be dedicated to figuring out the best way to integrate Cummins’ engines and other products into customers’ machines. Cummins is an independent engine manufacturer so a lot of the company’s products are sold to customers who build trucks and other equipment. The company wants to be a partner in its customers’ success so product integration is critical.

But there will also be “real world” testing going on at the center into the concepts the company is exploring for possible use in the future.

The center is merely the latest step in the company’s innovation efforts over the past year. Cummins acquired several companies to enhance its electrification efforts. It opened a new technical center in India in March and celebrated the 50th anniversary of its technical center in Columbus in October of 2017.

In NASCAR, this Job is Never Truly Done, but the Hauler Driver can Always Count on Cummins

The hauler containing Clint Bowyer’s No. 14 Ford depends on a Cummins engine to get the NASCAR team to its next race.
The hauler containing Clint Bowyer’s No. 14 Ford depends on a Cummins engine to get the NASCAR team to its next race.

When Bill “Stump” Lewis pulls the hauler containing Clint Bowyer’s No. 14 Ford into the next track on the NASCAR circuit, he knows there’s a pretty good chance he’ll never see the actual race. 

Lewis is usually busy packing the Cummins powered tractor-trailer during a race to get back on the road as quickly as possible after the checkered flag falls.

Every second counts, both on and off the track, for Bowyer’s team, which is sponsored in part by Cummins in 2018. It’s just part of the job, says Lewis, who has been doing this kind of work for more than 20 years. 

“Sometimes I don’t even know who won the race,” he said with a laugh, taking a short break from his duties for Stewart-Haas Racing (SHR) earlier this season at the Michigan International Speedway in Brooklyn, Michigan (USA).

It’s OK, the affable Lewis says, driving the truck is still one of his favorite parts of the job.


Hauler drivers are typically the first to arrive at a track for a NASCAR team and often the last to leave. Some say they have the toughest job on the circuit and that’s easy to understand listening to Lewis describe his typical week during the season.

It starts at the SHR garage in Kannapolis, North Carolina (USA), where Lewis gets everything loaded into the hauler – including two cars, nearly enough parts to build another, tools of all sort, and the electronic equipment used to evaluate a car’s performance on the track. Lewis is even in charge of the snacks served in the team break room inside the hauler – which usually means he makes a trip to the grocery store before leaving town.

By the time the hauler hits the road, it’s filled either at or near the legal limit – 80,000 pounds. When he gets to the track, Lewis’ work is just beginning. He gets everything out and positioned, so the crew can get right to work the minute they arrive on site. Even at 66, Lewis can run circles around many of his younger peers on the NASCAR circuit.

For select races, the Cummins logo will appear on the hood of Clint Bowyer’s No. 14 Ford for Stewart-Haas racing.


It’s a tough job, agrees Gary “Bear” Geissman, who is the fleet manager for SHR and has been involved in the racing transportation business in various capacities for some 40 years. He oversees all of the team’s haulers and 16 to 18 drivers. Sometimes more than one driver is needed if a trip takes more than the legal time limit before a driver must rest.

The SHR team’s haulers are usually on the road for more than 220 days a year, each covering about 70,000 miles annually, crisscrossing the United States under all kinds of driving conditions. There are seldom any “empty miles” that other truck drivers experience heading home after a delivery.

Keeping the haulers clean and in top condition is paramount. First, they each carry about $1.5 million worth of equipment, Geissman said. If that weren’t enough, the haulers amount to rolling billboards for teams and their partners. 

In certain locations, the haulers even have their own rabid fans. After NASCAR’s stop at Watkins Glen International in upstate New York, Lewis said people were lined up for miles on the sides of the road to see the haulers head south into Pennsylvania.

Nobody wants to get stuck by the side of the road, the drivers of a stock car hauler perhaps least of all. They know a race has never been delayed or cancelled because someone’s hauler had engine trouble getting to the track.

Lewis says torque and dependability are key to getting his job done and Bowyer’s hauler has had a 600-horsepower heavy duty Cummins engine for about three years. 

“We are at maximum load with our trucks,” said Geissman, who’s worked with Cummins engines for most of his career. “With a Cummins engine we get the power we need to pull all of our equipment. We can get up to and stay at the speed limit, and our Cummins engines are really good on fuel, too. ”

Hauler drivers have enough to worry about. They shouldn’t have to worry about their engines, too. 

The Cummins’ name debuted on the No. 14 Ford of driver Clint Bowyer at the Aug. 18 Monster Energy NASCAR Cup Series race at Bristol (Tenn.) Motor Speedway. Cummins will return to Bowyer’s car for the Oct. 15 race at Talladega (Ala.) Superspeedway.

Cummins Joins Council Promoting Hydrogen as a Future Energy Source

Cummins' membership in the Hydrogen Council will support the company's efforts to develop its capacity with alternative forms of energy.
Cummins' membership in the Hydrogen Council will support the company's efforts to develop its capacity with alternative forms of energy.

Cummins has joined the Hydrogen Council, a global coalition exploring and promoting hydrogen as a clean energy source to help meet the world’s climate challenges.

The company is one of eight new members joining the council’s steering committee, the group announced today (Sept. 5, 2018) in Brussels, Belgium. An additional six entities joined as supporting level members.

“Over the last 18 months we have brought together a critical mass of members, laid out a clear path forward to realize a global scale up of hydrogen in our ‘Hydrogen, Scaling Up’ study and fostered new actions with governments around the world,” said Dr. Woong-Chul Yang, vice chairman of the Hyundai Motor Company and co-chair of the Hydrogen Council. “There is more to come – look out for more exciting announcements from the council as we come together during the Global Climate Action Summit next week.”

Today’s announcement is the latest development in Cummins’ efforts to explore and support the use of low-carbon energy sources to help address global climate challenges.

The company has been working quickly to develop its own capabilities in electrification, establishing a new Electrified Power business segment in 2018. Leaders have pledged to have an electric powertrain system for the urban bus market by the end of 2019.

Cummins recently acquired several companies to help the company develop its expertise in electrification including Silicon Valley (USA)-based Efficient Drivetrains, Inc., which designs and produces hybrid and fully-electric power solutions for commercial markets, Oregon (USA)-based Brammo, which designs and develops battery packs for mobile and stationary applications and U.K.-based Johnson Matthey, a high-energy automotive battery business.

In addition, Cummins announced in 2017 it was partnering with Microsoft to study the use of natural gas-powered fuel cells as an energy source for datacenters, potentially allowing them to unplug from the grid.

Cummins wants to offer its customers a broad portfolio of clean power options, including clean diesel, natural gas and electrification, to help them best meet their sustainability goals.

The company has also been working to diversify its own use of energy. Cummins last month celebrated the start of construction at a northwest Indiana wind farm it is supporting through a financial arrangement called a virtual power purchase agreement. The expansion, when it comes fully on line in 2019, will produce energy equal to all of the electricity the company uses in its headquarters state of Indiana (USA).

The Hydrogen Council now has 53 companies within its membership, including Daimler, General Motors, Toyota, Honda, 3M, Airbus and Royal Dutch Shell. The group has more than quadrupled in size since launching at the World Economic Forum in Davos, Switzerland, 18 months ago. Today’s announcement comes ahead of the Council’s next annual CEO meeting, which will take place during the Global Climate Action Summit in San Francisco, California (USA) next week. 

The council shares the joint vision of hydrogen potentially averting 6 gigatonnes (Gt) of carbon dioxide (CO2), creating a $2.5 trillion market that will provide employment for more than 30 million people by the middle of the century.

Hydrogen is currently being used on a limited basis as a source of energy in fuel cells powering cars. It still faces technical challenges regarding its production, transportation and distribution.

Cummins Roars Back Into NASCAR Competition

The company looks to add to its rich racing heritage through a partnership with Stewart-Haas Racing and driver Clint Bowyer.

Cummins recently announced that it is returning to stock car competition, with the company inking a three race deal to sponsor the No. 14 Ford driven by Clint Bowyer of Stewart-Haas Racing (SHR) in the Monster Energy NASCAR Cup Series. 

Cummins will sponsor Bowyer’s No. 14 car at three of the most prestigious races on the NASCAR calendar: Bristol, Indianapolis and Talladega. While the sponsorship provides Cummins a unique opportunity to connect the company’s brand to innovation, dependability and success, it isn't Cummins' first foray into motorsports. Quite the contrary. In fact, the company's involvement in motorsports can be traced back to the founder of Cummins himself, Clessie Cummins 

"Cummins has a nearly 100-year commitment of developing innovative technologies that enable our customers’ success," said Amy Boerger, Vice President of Sales, Cummins Inc. "We are pleased to partner with Stewart-Haas Racing, a company that shares this deep commitment to innovation and success, as we add another chapter to our rich heritage in auto racing. Personally, I cannot wait to see the Cummins brand back on the racetrack with Clint Bowyer and the No. 14 team."

Read: "Cummins and the Indianapolis 500: A Time-Honored Tradition in Racing." 

The sponsorship is a homecoming of sorts for Cummins, which has deep motorsports ties in IndyCar and NASCAR. Cummins’ racing lineage dates back to the inaugural Indianapolis 500 in 1911 when Clessie Cummins, the company’s founder, served on the pit crew for Ray Harroun’s winning Marmon Wasp. A Cummins powered IndyCar also sat on the pole for the 1952 Indianapolis 500, the only diesel powered car to hold that distinction, and Cummins was the primary sponsor for Al Unser Sr. who won the Greatest Spectacle in Racing in 1987.

The Cummins Diesel Special
The Cummins Diesel Special was an innovative Indy 500 Roadster that set a recording-breaking pole speed of 138 MPH at the 1952 Indianapolis 500 Mile Race. 

In the stock car world, Cummins adorned Mark Martin’s Ford in the 1990’s, often appearing on the Hall of Famers iconic red, white and blue paint schemes. Martin drove Cummins sponsored cars to 25 victories during the heyday of NASCAR. 

The sponsorship also provides the opportunity for the company to partner with one of Columbus, Indiana’s favorite sons, Tony Stewart. Stewart is a co-owner of SHR and echoed his excitement to see Cummins return to stock car racing. 

For as long as I can remember, Cummins and motorsports were one in the same, said Stewart, the three-time NASCAR Cup Series champion, 1997 IndyCar Series champion and four-time USAC champion.

"Cummins always had a presence in the Indianapolis 500 and I remember seeing their logo in NASCAR for years with Mark Martin," added Stewart. "To be able to team up with a hometown company and help Cummins grow its business with another SHR partner in Rush Truck Centers, is something I take a lot of personal pride in. I know what winning feels like as a driver, but this is what winning feels like when you’re a team owner." 

Be sure to tune-in and watch Clint Bowyer drive the Cummins sponsored car at the following races:

  • Saturday, Aug. 18 – Bristol Motor Speedway (NBCSN)
  • Sunday, Sept. 9 – Indianapolis Motor Speedway (NBCSN)
  • Sunday, Oct. 14 – Talladega Superspeedway (NBC)
