This Earth Day, we are thrilled to announce Delta Americas has received a 2026 SEAL Business Sustainability Award for dramatically reducing its greenhouse gas (GHG) emissions and rapidly adopting renewable energy.
It's the kind of news that lands well on Earth Day. But the work behind it? Decades in the making. Delta’s mission—"To provide innovative, clean, and energy-efficient solutions for a better tomorrow”—has guided our operations and product development since the company’s 1971 founding by the visionary Bruce Cheng.
Delta’s focus on climate action and energy transition is as baked in as can be. The SEAL Award is the latest acknowledgement that our focus and strategies are creating extraordinary environmental benefits today, not in some hoped-for far-off future.
The Numbers That Earned It
SEAL stands for Sustainability, Environment, Achievement, and Leadership. The organization's Business Sustainability Awards recognize companies that prove "measurable environmental progress happens when innovation, operations, and leadership align around impact."
When it considered Delta for its award, the SEAL organization heard an emissions story as straightforward as these numbers: The Americas region cut its annual carbon emission from about 3,600 metric tons (MT) of carbon dioxide equivalent (CO₂e) in 2021 to around 1,750 MT in 2024. That’s a reduction greater than 50%.
And on the energy side, the region went from only 28% renewable-powered electricity in 2021 to using 100% renewable electricity across all its 32 facilities in 2025. (For more details on how Delta achieved this awesome milestone, see Delta Americas Reaches RE100—Five Years Ahead of Schedule).
Even more impressive, Delta got these results without impacting any of its business growth, as quickly as we could’ve imagined. That's what decoupling environmental impact from business expansion looks like.
How Delta Got There: A Tiered Renewable Energy Strategy
The company's primary decarbonization lever is its ability to source electricity. That’s because Scope 2 emissions, from purchased electricity, make up the largest share of its operational footprint. Delta ranks its action plan by positive environmental impact:
- Top priority: Self-owned solar installations, which deliver the greatest environmental benefit by adding new, clean capacity to the grid. For example, Delta has built a 1.1 MW system at its US headquarters in Fremont, CA; a 0.425 MW solar array paired with a 1.2 MW battery at its Detroit facility; and a 1.53 MW system at Delta Intelligent Building Technologies.
- Second priority: Power Purchase Agreements (PPAs) and Green Electricity Products (GEPs). These fund the development of new large-scale renewable projects rather than just crediting existing capacity. The current roadmap will get us to more than 70% by 2030.
- Lowest priority: High-quality, locally sourced Renewable Energy Certificates (RECs) from programs like Green-e, EcoLogo, and I-REC. These are a last resort to close any remaining gaps. Nevertheless, Delta sources RECs abiding by the strictest standards available, committed to create additional community and environmental values.
The Secret Sauce: Internal Carbon Pricing
In 2021, Delta introduced an Internal Carbon Pricing (ICP) mechanism set at $300 per metric ton of CO₂e. Every Americas facility pays carbon tax into a central carbon fund based on its emissions.
Under our ICP mechanism, facilities cannot avoid paying carbon tax by purchasing any kind of carbon offset. This creates a true momentum to move away from carbon emission generating activities, rather than just on-paper reductions.
Then Delta reinvests this carbon fund in its operations. Any facility can propose using the carbon fund as much as it wants, as long as the fund is reasonably invested in renewable installations, efficient resource management, and low-carbon innovations. This creates truly a self-reinforcing loop that rewards genuine decarbonization.
In just three years, from 2022 to 2024, Delta Americas internally allocated $10.3 million from its ICP funding to targeted projects.
Looking Forward
Delta's broader commitments, including its Net Zero 2050 target, provide the long-term arc. We expect to expand the ICP system to cover broader emission categories, ensuring even stronger accountability across the company’s entire value chain.
The SEAL Award is a welcome recognition that affirms the Delta model: Rigorous measurement, tiered renewable investment, and a financing mechanism that makes low carbon operation the financially rational choice.
For a company whose mission has always been to power a better tomorrow, this Earth Day feels like a good time to pause and bask in our sustainability accomplishments to date. Then it’s back to work.
