It is separated into five areas of focus: Education: Gain company buy-in for your environmental initiatives. From senior management to all employees, it is up to everyone to make sustainability work within their space. Employee education and participation is the key! Utilities: This section will make you aware of the amount of electricity and water used in your space and provides various ways to decrease or limit that usage. Office equipment accounts for approximately 31% of the average tenancy’s energy use. By simply turning off equipment and computers before leaving the office you can decrease the amount of energy used in your space. What is the Green Tenant Guide?

Travel: Since transportation accounts for over 20% of CO 2 emissions, this section provides ways to decrease emissions by traveling smarter to work. The CTA replaces the equivalent of approximately 400,000 vehicles on area roads each weekday. Encouraging employees to use public transportation assists with the reduction of CO 2 emissions. Waste: All JBC managed buildings have a recycling program in place. This section provides tips on how you can further decrease the amount of paper, plastics, and electronic equipment waste generated in your space. Setting your copier to print double sided reduces the amount of paper waste, which is 55% of the total trash typically created in an office. Purchasing: This section provides suggestions on what items to purchase that will have a minimal impact on the environment. By using a water cooler instead of purchasing plastic water bottles, we can reduce part of the 80% of plastic waste that ends up in landfills.
