Environmental Stewardship

• Dominion sponsors the Virginia and West Virginia Envirothon programs, which encourages high school students to be actively engaged in the environment around them. Students participate in both written and hands-on competition relating to a specific environmental issue. Teams from across the country compete for the chance to earn thousands of dollars in scholarships.

• Dominion’s approach to the environ-ment goes beyond a compliance mindset to a culture of stewardship. To find out more, visit Dominion’s Citizenship and Sustainability Report online at www.dominioncsr.com.
