Making strides in sustainability

Black Hills Corp. reported a 27% reduction in greenhouse gas emissions from its natural gas distribution system since 2022. This marks meaningful progress towards its goal to achieve net zero emissions by 2035. Additionally, the company has reduced its electric utility greenhouse gas emissions by nearly one third since 2005 and is on track to achieve its goal to reduce electric emissions intensity 40% by 2030 and 70% by 2040 compared to 2005.

“We're committed to creating a cleaner energy future that builds upon our responsibility to provide the safe, reliable and cost-effective energy that improves our customers’ lives,” said Evans. “We strongly believe that multiple energy sources, working together, will provide the solutions for a cleaner and resilient energy future.”

Additional report highlights include:
