SS i am very proud of you! Here are a couple things:

Consider purchasing reusable cloth bags to shop for your groceries with instead of using the stores plastic bags, many grocery chains now sell them and they run about 3-4 dollars each. Plastic bag manufacturing consumes a lot of oil and causes a lot of pollution.

Make sure you keep the tires in your car properly inflated, it has been estimated that collectivly in the US we waste millions of gallons of gas and cause a lot of unecessary carbon emissions from underinflated tires
