I'm doing this energy poster at school and I need a slogan, I'be thought of some, what do you guys think? Any ideas?

It has to relate to planting shade trees to reduce CO2, or painting your house a light color if you live in a warm climate and painting your house a dark color if you live in a cool climate.

Which one do you think? Less CO2 pollution is a great solution. Less Co2 pollution is the best solution. Be a saint, Plant and Paint. (?? is that appropriate for school?) Give a hoot, don't pollute. A good solution is no CO2 pollution.
