I believe there is a difference in the calculation of my carbon with my family invovled. There are only two people in my home. My carbon usage would be way lower if my father wasnt included. He likes to leave the water running while not using it. He also turns the air on when we have fans. He leaves the lights on all day. I try to turn them off as much as i can. If i had my own home i would live in a town. hopefully near school and work. If i lived near school and work i could walk to get there. Things would be easier.
