It’s cool to conserve energy! Most households in Canada use natural gas and oil to keep cool in the summer. On average, an air conditioner emits 1026 kilograms (kg) of carbon dioxide (CO2) every year. During the hot summer months, for every degree the temperature is raised above 22.20C , cooling costs drop by 3% and CO2 emissions decrease by 55kg. In the summer, you can reduce emissions by turning off (or down) your air conditioning. Switching off a central air conditioner in a typical house of 232 square metres will save a full 2,000kg CO2 per year. If you have room air conditioners, switching them off will save about 425kg per year per room.
