I will keep lights, electronics, and appliances turned off when not using them.

I will avoid wasting water while waiting for the shower or sink to heat up.

I will switch to washing my clothes in cold water, saving up to 1,600 lbs of CO2 over the course of the next year.

I will adjust my thermostat down 2 degrees from usual when I use the heat, and up 2 degrees when I use air conditioning.

I will research the social or environmental issues in my community that matter to me and tell 2 friends and/or colleagues each day about what I learn.
