Mastercard 14.6 MW
On-Site Solar Project
A multi-site on-site solar portfolio supporting Mastercard's commitment to renewable electricity and operational carbon reduction. The projects contribute to the company's broader climate strategy while reinforcing long-term energy resilience and sustainability leadership.
Background
Mastercard has publicly committed to advancing renewable energy adoption across its global operations as part of its broader climate and sustainability initiatives. The company has set science-based emissions reduction targets and continues to pursue strategies that support long-term decarbonization of its facilities.
To support these objectives, Mastercard implemented on-site distributed solar installations at select U.S. locations. The systems contribute directly to renewable electricity generation at the point of use, reducing reliance on grid-supplied power and supporting measurable progress toward corporate climate commitments.
On-site solar plays a strategic role in helping corporations stabilize long-term energy costs, reduce exposure to utility volatility, and demonstrate tangible environmental leadership.

Year: 2026
Supporting Corporate Climate Commitments
Mastercard has publicly committed to achieving net-zero emissions across its value chain by 2040, with science-based targets aligned with climate science and an ongoing expansion of renewable electricity sourcing across its operations.
On-site solar installations directly support these commitments by increasing renewable electricity generation at owned facilities, reducing Scope 2 emissions associated with purchased electricity, and providing visible infrastructure investment aligned with ESG priorities. Distributed solar complements broader renewable procurement strategies — such as renewable energy credits (RECs) and utility-scale power purchase agreements — by adding resiliency and localized generation capacity.

On-Site Solar in Corporate Strategy
Estimated Emissions Reduction Impact
For large corporations with energy-intensive facilities, distributed generation offers several strategic advantages. On-site production provides long-term energy cost predictability, reduces dependency on grid fluctuations, delivers measurable facility-level carbon reductions, and demonstrates visible sustainability investments for employees, customers, and investors.
Projects such as Mastercard's illustrate how corporate facilities can serve as active participants in the energy transition rather than passive energy consumers.
