Delta: Working Toward Net Zero Through Sustainability, Climate Impact
Delta Air Lines employs 95,000 people and operates 4,000 flights a day, flying to more than 280 destinations on six continents, and expects to serve nearly 200 million customers this year. 13.7 million passengers flew in or out of Detroit Metro Airport in 2022, making it Delta’s third-largest hub. We interviewed Gail Grimmett, Delta’s senior vice president of sustainability performance and strategic partnerships, to learn more about the airline’s sustainability strategy. Q: How does Delta approach sustainability? A: We are on a journey to reach net zero by 2050, so we have milestones and smaller goals we are working toward for 2025, 2030, and 2035 to help us get to net zero. Our goals fall into two main pillars. The first is to embed sustainability in everything we do. This allows us to concentrate on things we can control today and allows sustainability to penetrate the entire business. The second is to eliminate our climate impact from flying. This is where our fuel and fleet come into play. So, we focus on these two main pillars and have set key targets and goals for each. Q: What does your sustainability team look like and how is it organized within the company? A: It’s set up to support the pillars. We have councils set up across the organization that work toward our goals. For example, we have a Carbon Council that is led by our chief of operations. This group is focused on innovation and fuel usage, looking for fuel efficiencies and savings Last year we saved 10 million gallons in fuel by weight reduction and by flying in a more efficient manner such as altitude and speed. We have sustainability embedded across the organization working on finding efficiencies and opportunities in areas we can control today. Q: Is sustainability addressed any differently here? A: All airports are different, but because we have great partners with the Airport Authority, we’re able to make changes outside of just our operation, like with LED lighting, low-flow water within the terminal, and within our catering kitchens. Since Detroit is a hub, it is a key airport for us that we look at regularly. We’ve been working on electrifying our ground service equipment (GSE) to convert to 100% electric by 2025 in five of our hubs and 100% in all of our hubs by 2035. Q: What are your short-term sustainability goals? A: In the short term, we are focusing on what we can control within our operation. For example, leveraging our councils to reduce fuel usage by another 10 million gallons this year. By 2035 we expect the Carbon Council to have saved 1.1 billion gallons of fuel, which is important from both a cost and emissions perspective. We are eliminating single-use plastics from planes. We eliminated 4.9 million pounds of plastic from planes as of last year, and on Dec. 5, we announced a new paper cup that we are testing in-flight that once fully rolled out will eliminate another 7 million pounds of single-use plastic. Changes like a new paper cup are no easy task. These cups must handle both hot and cold materials and meet international regulations that can vary from country to country. We’re a global airline, and, operationally, we can’t just stock every aircraft differently based on the countries they travel through. We have to satisfy the sustainability regulations of all countries on all planes. Q: What about longer-term goals? A: We need to be net zero by 2050. That is the goal everyone in the industry is racing toward. To accomplish this, we need to focus on large-scale changes – things like switching to sustainable aviation fuel and hydrogen to power aircraft and building the supporting infrastructure. All this is still being researched and tested. When we think about our fleet – what we fly and how we fly – we are looking at what we can do in the medium term and the long term. For example, each new aircraft we add to our fleet generates around 25% fuel savings, so we are also updating our fleets to be more efficient. Q: What else are you working on to get to net zero by 2050? A: The number one lever we can pull to decarbonize our industry is sustainable aviation fuel (SAF). Currently, there is not enough of it, so we need to ramp up production of it. Today, there is only enough SAF to barely cover one day’s worth of flying for the entire industry. The government and policymakers are important as the production of SAF scales because we need the right policies and incentives to increase production and build the infrastructure to support SAF. While that may seem daunting, a positive is that SAF is an immediate solution – it can be added directly into planes right now. So, while there isn’t enough of it, it can be blended with current fuel, so we can start with 50% SAF and move to 80% and then 100% as the production ramps up. Also, this first-generation SAF won’t be the last. It will continue to evolve. This is one of the most exciting times to be in this field as there is so much need here, and so much innovation happening. Q: I read that you focus on building your fleet to have the longest, most sustainable life possible. Can you tell us more about that? A: Circularity is important to us. We look at refreshing planes, regenerating materials, and recycling. We hold onto our fleet for a long time but continually look at how to be more efficient with the fleet. Adjustments are being made to certain planes to reduce drag, which helps them become more fuel-efficient. This goes back to controlling what we can control while continuing to refresh the fleet as we can. Q: What are the biggest challenges overall? A: There are two. The first is the pace of technology advancement. It needs to speed up and I think it will. And,
Detroit Greenways Coalition’s Todd Scott Talks Greenways and Sustainability
The Detroit Greenways Coalition (DGC) works to promote and build a network of greenways, Complete Streets, and bike lanes that will connect people and places, improve the quality of life, beautify neighborhoods, and stimulate neighborhood-level economic development in Detroit. Its mission is to create, conserve and promote greenways and green spaces to connect people, places, and nature. Its vision is a strong, healthy, vibrant City of Detroit and a region where a seamless network of greenways, green spaces, blueways, and Complete Streets are an integral part of people’s active lifestyles including day-to-day transportation and recreation. SBN Detroit spoke to DGC Executive Director Todd Scott to gain insights about their work. Q: How big of a driver was sustainability for the city of Detroit in the forming of the Greenways Coalition? A: In the beginning, we had to tackle more basic issues about how to build and maintain greenways across the entire city and how to make green transportation easier and safer. Our vision was certainly supporting sustainable transportation and green space, but we were focused initially on more basic issues. Some examples here are developing a citywide greenway network vision, advocating for redesigned city streets that better accommodate green transportation, and finding the resources to make this all a reality. Over time we’ve been able to move beyond these issues and push sustainability more, especially in light of the need for Climate Action – reducing transportation carbon emissions and providing green stormwater management. Q: The vision of the Greenways Coalition is ultimately to connect every neighborhood over time. Please speak to how this impacts the city in terms of sustainability from these aspects: Environmental: Greenways and Complete Streets (i.e. streets designed to safely accommodate all users) can do more than provide green transportation. They can help manage stormwater through green stormwater infrastructure, street trees, and even de-paving roads. They can also reduce urban heat island effects. Flooding and extreme heat are big issues in Detroit that our work can help address. Transportation/Mobility: The most important impact is how these connections help Detroiters use green transportation. That’s not just walking and biking, but public transit as well. They provide safe and convenient routes that connect schools, jobs, parks, retail areas, and more. Economic: There are many examples of greenways and Complete Streets driving economic urban revitalization around the world. Locally, there may be no better example than the Livernois Avenue of Fashion. The streetscape project reduced vehicle travel lanes (and speeding), widened sidewalks, and added bike lanes. Businesses along the route have flourished. There is a tremendous opportunity for additional retail revitalization along the 27-mile Joe Louis Greenway. It will be interesting to see how places like the Oakman/Grand River strip and even Downtown Hamtramck increase business activity as a result of the greenway and the bike and pedestrian traffic that it brings. Social/Inclusivity: Biking and walking can be very social. We’ve seen this with the numerous biking and walking clubs that have formed across the city over recent years, but especially during COVID. Greenways and Complete Streets support these club events that are open to everyone. Q: Does the Greenways Coalition have a set of sustainability goals? A: What we largely do is advocate for institutions to have sustainability goals. We’ve done that with the City of Detroit through their Sustainability Action Agenda. We’ve been heavily involved in the carbon neutrality discussion at the state level through the MI Healthy Climate Plan. We’ve even weighed in on federal issues, such as the recently proposed U.S. DOT Greenhouse Gas Emissions rule. You could say our agenda is to get sustainability incorporated at the institutional level so that it leverages the benefits of our vision. Q: From a sustainability standpoint what are the direct benefits the Greenways offer to Detroit residents? A: The largest direct sustainability benefit is transportation. Greenways provide “green ways” to get to destinations around the city and to connect with public transportation. The “green” in greenways has multiple meanings. It’s more than just landscaping, it’s about sustainable transportation. It’s also about saving some “green,” e.g. money. Sustainability can benefit Detroiters, but that benefit must also improve the financial sustainability of the household budget. Vehicle transportation can eat up a large portion of that budget. Greenways can benefit many and reduce that burden. Be sure to subscribe to our newsletter for regular updates on sustainable business practices in and around Detroit.
