Making different food and beverage choices can decrease your carbon cost: eating a locally-grown apple instead of a banana flown in from Ecuador, or passing on a tilapia fillet which has been frozen using electricity from a coal-fired power plant and flown in from China on a carbon-dioxide-emitting jet. The company also encourages drinking tap water instead of bottled water.
