At Clif Bar, maker of foods and energy products, an employee can get $500 to buy a commuter bike. If workers carpool, ride bikes, use public transportation, or walk, they earn points toward a maximum of $960 in annual rewards. Employees can get $6,500 contributed toward buying a car with a hybrid, biodiesel, or natural gas engine. Since 2008, 79 of 192 eligible employees have used the bike incentive and 56 have taken the car incentive, according to Jennifer Freitas, Clif Bar's human resources manager. Aside from incentives reducing the amount of carbon dioxide in the air, Freitas says "employees are enjoying healthier, more relaxing ways of getting to and from work."
