Global Warming Question. (Don't want anything saying that global warming is fake.)?

Ok, I'm doing a report on global warming, and what solutions we have to prevent global warming. The solution I chose was that we could walk more, and become more energy efficient. Now I have to have statistical date to back up what I'm saying. Is there any data that has something like "Cities with many walkers have less carbon emissions." Or, "Homes with flourescent lightbulbs release less carbon emissions." I really need something like that. Thanks!
