4. Ditch the Car!
Not only does driving less reduce emissions in the atmosphere but you also save on petrol and walking and biking are great forms of exercising. Also look at public transport and car-sharing to work or school. When you do have to drive, however, make sure that you are using your car effectively. Check your tires are properly inflated – having properly inflated tires can improve your mileage by more than 3%. Every litre of petrol you save not only helps you save money but it also helps reduce carbon emissions.
