What can we do in UAE to reduce CO2 levels?

Here in U.A.E many of us can do a good thing to prevent the global warming. Even in our houses we can do a good job to decrease the danger of the global warming. The main thing that causes the global warming is burning fuel and gasses through factories and plants. We can reduce using electricity in our houses to decrease the pressure to electrical generators which depend and work using fuel and gas. Also instead using a 4 wheel cars we can use a small cars with 4 cylinders which consumes a small amounts of fuel. In the same case we can increase using of cars which work by gas instead of oil because it is less harmful to the environment and don’t consume gas a lot. Adding to that we can switch on the screen saver in our computers when we don’t use them to save the battery which depend on the electricity. All of these are a simple things which we can follow them easily and encourage other people to follow them.
