New Dominion Bank and the recruiting firm Sherpa don't have much in common, but the two Charlotte companies have been in a heated competition since June 1.
The winner will have added the least pollution to the city's air this summer.
The competition began when two Sherpa employees - Kori Renn and Heather Tatum - decided they wanted to step up the company's involvement in Clean Air Works!, a Charlotte-based program helping 116 businesses improve air quality.
Employees gain points for carpooling to work and to lunch, using public transit, swapping old light bulbs for energy-efficient ones, refueling cars after 6 p.m. and using reusable grocery bags.
Combined, the companies' actions have saved 2,985 miles in vehicle usage - by carpooling to work or walking to lunch - and 1,941 grams of nitrogen dioxide, a chemical that adds to the formation of ground-level ozone and can have adverse affects on the respiratory system, Dory said.
An average commute for a Charlotte resident - about 24 miles round-trip - creates 15 grams of nitrogen, according to Mecklenburg County air quality emissions.
