Plant Green plants with less water and more trees to provide shade

While it is true that planting more trees will help in the short term because they essentially soak up carbon, they also release carbon dioxide when they die. So it just postpones the problem. But there are other reasons to plant trees - as wind breaks to save energy, and as shade to lower cooling costs. And even the short-term help while we get our act together is a good thing.

As for plants, do everything you can in your yard and garden to create ways in which plants use less water. Choose hardier plants, plant things in groups that need more water and put in mulch to help keep moisture in. When you mow your grass, make sure you do it smartly - with sharp blades, and only when the grass needs cutting. Finally, make sure you water your lawn sparingly. All of these will conserve energy.
