IF EVERY SUNSET READER DID ALL THESE THINGS

• Replaced 1 incandescent lightbulb with a compact fluorescent bulb (CFL), we'd save 2 million pounds of CO2 per day

• Reduced their driving by 1 mile every day, we'd save 4.8 million pounds of CO2 per day

• Washed their clothes in cold water, we'd save 2.4 billion pounds of CO2 per year

• Line-dried 1 load of laundry once a week, we'd save 836 million pounds of CO2 per year

• Turned down the thermostat 2° (to 68°) in winter and up 2° (to 78°) in summer, we'd save 26 million pounds of CO2 per day

• Unplugged their electronics when not in use, we'd save at least 13 million pounds of CO2 per day

We'd save 20 billion pounds of CO2 per year, the equivalent of 2 million fewer cars on the road for 1 year.
