Let's lead by example, therefore 12 Simple Things You Can Do to Reduce Your Carbon Footprint from UNDP (see full ad here):
Turn it off
Turn off lights, televisions, videos, stereos, heaters, cars and computers when not in use - they can use 10 to 40% of the power when on standby. Also, unplug chargers as soon as they have finished charging.
Fill the kettle with only as much water as you need.
Don't leave fridge doors open for longer than necessary.
Check your tires
Properly inflated tires can improve your car’s fuel efficiency.
Use no plastic
Use cloth bags when going shopping and avoid buying products which use too much plastic.
Instead of using air conditioners in the summer, wear cool clothes, and use a fan.
Do your weekly errands in a single trip or pay your bills online. Walk, bike, ride the bus or carpool.
Optimize your speed
You will consume up to 25% less fuel if you drive no more than 90 km/hr.
A hybrid or other fuel-efficient car emits less carbon dioxide.
Replace your incandescent bulb with a compact fluorescent light bulb (CFL). CFLs cost 3 to 5 times as much but use less than a third of the power. Also, replace old fridge and other appliances with energy-efficient ones.
Watch what you eat
Choose food produced close to your home.
Consume less, and re-use old products.
