• Bring a reusable coffee mug or water bottle and refill it throughout the day to reduce disposable paper cups and plastic bottles.
• Bring your own lunch in reusable containers.  Food vendors often produce lots of waste from disposable containers and packaging. 
• Try to minimize the use of elevators by taking the stairs; it also makes good exercise.
• Choose a laptop instead of a desktop. They consume 5 times less energy.
• Do online readings on the computer and avoid printing them out.  If printing is needed, try to print double sided and/or fitting two pages on one side of the paper.
• Use laser printers instead of ink cartridge printers.  Stacked end to end, cartridges thrown away in North America in 1 year would cover a distance of over 38,000 km - enough to circle the earth.
• Reuse single-sided print-outs as scrap paper.
• Turn off your computer monitor and set your computer to stand-by or sleep mode when you’re not using it.  You can set your computer and computer monitor to automatically go to stand-by or sleep mode by a timer (5 minutes recommended).
• Rent a bus to get to and from a large group off-campus event or arrange car-pooling.
• Compost food scraps after an event.  If the 21.5 million tons of food residuals generated annually were composted instead of being sent to landfills, the resulting reduction in greenhouse gas emissions would be equivalent to taking more than 2 million cars off the road.
• Event planners should consider serving food in buffet style instead of boxed lunches or individually wrapped items and use refillable or reusable containers and serving products.
• Planning the event menu using local, seasonal produce and offer organic produce and meats, and fair trade, shade-grown, organic coffee.
• In a presentation, use projectors and distribute electronic copies to minimize print-outs.

• Buy recycled, chlorine-free paper and recycle office paper when you are finished with it.
• Reuse envelopes.
• Do not dispose used toners and cartridges in the garbage.  There are collection centers (Staples Business Depot) or some manufacturers will even pay for the shipping cost for your empty toners to be returned.
• Buy office supplies in bulk to minimize packaging.
• Turn off the lights when no one is using the office.

• Turn off the lights, television, computer, and stereo when you leave the room.
• If possible, line-dry your clothes outside in the summer.
• Ensure that windows and door frames are sealed properly to prevent heat from escaping in winter or cool air in summer.
• Lower the temperature of your hot water heater to 50ºC.  Setting your water heater temperature down 5ºC can save 3% of your energy costs.
• Look for the ENERGY STAR qualified symbol when purchasing new appliances.
• Keeping lids on pots when you are cooking will use up to 20% less energy and your food will also cook more quickly and evenly.
• Refrain from using outdoor power equipment during hot, hazy summer days when smog is a problem.
• Mow your lawn late in the evening, after 7 p.m. This gives ozone-forming chemicals a chance to dissipate overnight.
• Use snowblowers only for moderate to heavy snowfalls. Clear away light snowfalls with shovels.
• Solar pool covers can reduce water loss by up to 50%. The less water lost, the less energy you will need to use to heat your water. You will also reduce the amount of chemicals that you need to use.

• Walk, bike or take public transportation to school.  If driving is necessary, try car pooling or use a fuel efficient car.  One busload of passengers removes 40 cars during rush hour, saves 70,000 L of fuel, avoids more than 175 tons of greenhouse gases for that trip, and prevents 9 tons of air pollutants a year.  The SCSU also runs a free bike share programme.
• Change your highway cruising speed to 90 km/hr. Decreasing your highway cruising speed from 120 to 90km/hr will decrease fuel consumption by about 20%.
• Avoid abrupt stops and starts. The more smoothly you drive, the less gas you will use. Tests show that rapid starts and hard braking reduce travel time by only 4%. However, fuel consumption increases by 39% and emissions of toxic air pollutants are more than five times higher.
• Turn off your car's engine if you will be idling for more than 10 seconds. Ten seconds of idling uses more fuel than restarting the engine. Restarting your car many times has little impact on engine components, adding only around $10 per year to the cost of driving, money that is recovered in fuel savings.
• Avoid using a remote starter, since it will increase the amount of time your car sits idling.
• Remove unnecessary items from your trunk. The lighter your car, the higher your fuel efficiency.
• Try to use fresh air vents on the highway. Air conditioning uses around the same amount of fuel as having the windows open. Open windows are the worst option, since they create drag and force your engine to work harder.
  

• Sort your garbage into compost, recyclables and waste.
• Develope the habit of turning off the lights when you exit a room.
• Choose local and seasonal produce when grocery shopping.

• If every Canadian household swapped a 60W incandescent light bulb with a 20W CFL, 400,000 tons of GHG emissions would be prevented - the same as eliminating 66,000 cars - and $73M a year would be saved on energy.
• Recycling one plastic bottle will save the same amount of energy needed to power a 60-watt light bulb for 6 hours.
• Organic beef emits 40% less GHGs and consumes 85% less energy because the animals are raised on grass instead of concentrated feed. [source]
• LCD monitors use 80-90% less energy than conventional cathode ray tube monitors (CRT).
