If you've resolved to live a greener life this summer, you've come to the right place.

Your carbon footprint equals the total impact you have both directly and indirectly on greenhouse gas emissions. A significant portion of our personal contributions to greenhouse gas emissions happen in our homes, i.e. heating, cooling, electricity and water usage, and yes, cooking.

No matter how minute, every step you can take to waste less in your home counts. Here are 9 easy tricks you can use in the kitchen to live a more eco-friendly life.

Try a fridge thermometer.

Start by making sure your fridge and freezer aren’t too cold. Recommended temperatures are 35° to 38°F for the fresh food compartment and 0°F for freezers—anything colder means wasted energy.

Do a door test.

Make sure your refrigerator door seals are airtight. Test them by closing the door over a piece of paper so it’s half in and out. If you can pull the paper or bill out easily, the latch may need adjustment, the seal may need replacing, or you may consider buying a new unit.

Leave leftovers covered.

Cover liquids and wrap foods stored in the refrigerator. Uncovered foods release moisture and make the compressor work harder.

Fight off excess frost.

Regularly defrost manual-defrost freezers and refrigerators; frost buildup decreases the energy efficiency of the unit. Don't allow frost to build up more than one-quarter of an inch.

Pick a proper pan.

Make sure the cookware you’re using matches the size of the heating element. For instance, a 6-inch pot on an 8-inch burner wastes over 40% of the burner’s heat—this can save about $36 annually for an electric range and $18 for gas. Also, covered pots and pans will heat up faster and need less energy to hold it in than uncovered.

Keep your cooktop clean

A gas range’s burners will reflect heat much better when they aren’t hiding under burnt-on grime. Also, look for blue flames— yellow indicates that gas is burning inefficiently and may need adjustment from the manufacturer or your local utility.

Use small appliances

When able, cook with countertop electrics like a toaster oven, pressure cooker, or slow cooker rather than firing up your full-sized range. A toaster or convection oven uses a third to a half as much energy as a traditional oven (and you won’t have to crank up the A/C to cool down your house in warmer months).

Remember a tote

Bring reusable bags to the grocery store instead of using disposable shopping bags. As a reminder, you can stash a few next to where you keep your shopping list so they’ll be ready when you are.

Reduce, reuse, then recycle

When it comes to environmental impact, reusing trumps recycling. Only 14% of plastic packaging waste gets recycled, and out of this only 2% can be really recycled into equivalent products! Only recycle products when you cannot repurpose them.
