I will power down my computer and monitor when not using it for more than 2 hours, saving up to (1.1) lbs of CO2 each day that I do this.

I will naturally heat and cool my house, office, or dorm room by opening or closing my windows, curtains, and blinds, and by using fans.

I will switch to washing my clothes in cold water, saving up to 133 lbs of CO2 a month and 1,600 lbs of CO2 over the course of the next year.

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