Calgarian Krista Thomas usually commutes to her job at Devon Canada with two others, but has extra incentive this week as the company participates in the commuter challenge.

Thomas, who works in the communications department, said last year Devon Canada had 38 per cent of employees involved in the challenge and believes they will have more this year.

“We came first in a different challenge last year,” said Thomas. “We knew it was something our staff was really interested in.”

The commuter challenge, which runs until Friday, is a competition between workplaces and cities across Canada to use something other than single occupancy vehicles. In Calgary, 120 companies are embracing the challenge.

“This is a way to get people to engage in the behaviour that’s necessary for the city to take the steps to change the infrastructure,” said Kathryn Winkler, national commuter challenge leader.

Options that the commuter challenge is promoting are biking, transit, carpooling and teleworking. Winkler said it’s about finding sustainable options.

Commuters can track their greenhouse gas emissions, calories burned and money saved on

Prizes are awarded at the end of the week to companies that participate.
