Providing workplace charging is one of the more effective ways for businesses to reduce the greenhouse gas emissions of their employees’ daily commute. Offering a bike purchase subsidy can be even more cost effective but may not be suitable for all employees. Transit subsidies may be a good option but there is a wide range of potential costs from $284 to $1,231 per metric ton of carbon dioxide equivalent (CO2e). The vanpool subsidy has the highest cost of the options shown potentially exceeding $2,000 per metric ton of CO2e.
