Booz Allen Hamilton, a management and technology consulting firm, has released a tool that figures out the environmental impact of the NCAA tournament based on which bracket wins.

• The bracket with Louisville winning the tournament would have the smallest carbon footprint in the men’s tournament
• The bracket with St. Mary’s winning the tournament would have the largest carbon footprint in the men’s tournament
• The bracket with Maryland winning the tournament would have the smallest carbon footprint in the women’s tournament
• The bracket with UCLA winning the tournament would have the largest carbon footprint impact in the women’s tournament
