Your car is probably the item you own that makes up your largest source of personal pollution. While it’s difficult to go without a car, it is easy to make your car more environmentally friendly. You can do just a few simple things to reduce your carbon footprint and contribute to a better environment.
Open Your Windows
One of the easiest ways to make your car more eco-friendly is to reduce your air conditioning use. The air conditioner puts a significant load on your engine and reduces your gas mileage by up to 25% on short trips in very hot weather. On hot days, open your windows when you first start driving to flush out the hot air. On short trips around town when the weather isn’t too hot, ride with the windows down so you breathe in the nice fresh air while reducing your environmental impact. There are times when you don’t want to open your windows while driving and this is at highway speeds. The drag created by open windows actually is greater than the load placed on the engine with the air conditioner.
Don’t Load Your Car Up
Extra weight in your car will reduce your gas mileage and increase its carbon footprint. If you are carrying around weight in your car needlessly, you aren't doing anyone any good. You should look inside your car and see if you have anything in it that you don’t need. Remember things add up so even if a single thing doesn't weigh a lot, several of them can add up. This includes driving around with cargo box on your roof. Not only do you have extra weight but give you extra aerodynamic drag on your vehicle. Reducing your weight in your car can get you an extra 1% for every 100 lbs. of weight.
Drive More Conservatively
Are you the first one off the line when the green light shines? Do you look at the speed limit as just a suggestion? Do you love using your brakes? Any one of these habits can be costing you at the fuel pump. In fact, they could be costing you 20% to 60% more in fuel costs. If you are driving a late model sedan at speeds of 75 mph, you will use almost 50% more fuel than if you were driving 50 mph. Yes, it takes more time to get where you are going, but you are saving money and helping the environment in that extra time spent driving. The US Department of Energy maintains a speed limit fuel economy calculator that can tell you exactly how much you will save based on the year, make, and model of your vehicle.
Keep Your Check Engine Light Off
Computers are responsible for monitoring your sensors and ensuring that your car is running at optimal fuel economy. When one of the systems is not performing its best, the computer will turn on your check engine light. It’s easy to ignore the light if your car is otherwise running well, but it could be putting out significantly more pollution and damaging the environment. This is why it’s so important to keep your check engine light off. Many auto parts stores will do a free scanning of your system and let you know which parts or sensors need to be replaced. Sometimes, your fix can be as simple as tightening your gas cap.
Don’t Overfill Your Car
Topping off your tank seems like an innocent thing to do. Unfortunately, it is one of the worst things you can do at the gas station. Not only do you risk spilling fuel that will eventually get washed into your local rivers and streams, but you also risk damaging your fuel system. Every modern car has a charcoal canister to capture vapor so they can be burnt in the engine. When you overfill your tank, the excess fuel can saturate this charcoal canister. At best it loses efficiency and vents harmful gases to the atmosphere, but at worse, it can fail leaving you with a repair bill that can run into the hundreds of dollar.
It’s easy to implement these tips and not only save money but also help the environment. It’s clear that if you use these 5 ways, your car use will be more environmentally friendly.
