Are you already recycling? Carrying around a refillable water bottle rather than contributing to the ocean-bound plastic problem? Composting your food scraps? That’s all commendable, but there’s more to be done to achieve a net-zero lifestyle. If you’re ready to up your environmental commitment this year (and hold larger entities accountable along the way), here are a few ideas — some more dramatic than others — for sustainable resolutions in 2021.

Get rid of your car

If you have a car, sell or donate it. Once you’ve unloaded the gas guzzler, do your errands on foot or by bike. If you don’t have your own bike, join your city’s bike-share program. With proper COVID-19 precautions, take public transportation for longer distances.

Ditch the plastic liners

Do you know how long those kitchen trash bags take to decompose? Anywhere from 10 to 1,000 years. Instead, go au naturel and regularly clean your trash, recycling and compost containers.

Change your laundering style

Did you know that most of the energy it takes to run a washing machine comes from heating the water? Only 10% of energy is for working the machine, so switch to cold-water washing. Once your clothes are clean, hang them to dry. If you live somewhere sunny and have space for a clothesline, this won’t be too hard. If you live somewhere cold and rainy, see if you can hang an inside clothesline or set up a drying rack. But if this is impractical and you must run the dryer, make sure it’s fairly full so you make the most of the energy. Dryers are the third-biggest energy hogs in the average house, after the refrigerator and washer.

Forget the lawn

Lawns are a huge waste of space and resources. In the U.S., people spray about 3 trillion gallons of water on them every year, use 800 million gallons of gas in their lawnmowers and treat them with nearly 80 million pounds of pesticides. But who are we trying to impress with this golf course-looking terrain around our homes? Instead, go with xeriscaping or planting vegetables. Let clover take over, or fill your yard with pollinator-friendly plants.

Control your climate

Invest in ways to weatherize your home and lifestyle year-round. If you have the money and own a home, a heat pump can cut your energy use in half. Try low-tech solutions like wearing thicker socks and a fleece bathrobe over your clothes so that you don’t need to turn the heater up as much in winter. Add an extra blanket to the bed, and turn your thermostat down at least seven degrees at night. You use about 1% less energy per eight hours for every degree you turn it down.

In summer, air conditioning is a massive energy hog. Three-quarters of U.S. homes have air conditioners, which use 6% of the total electricity produced in the nation, according to Energy Saver. Annual cost? About $29 billion dollars and 117 million metric tons of carbon dioxide released. If you must use AC, don’t set it so low. Add insulation to your house. Wear a bikini. Eat more ice pops. Sweat a little, it won’t hurt you.

Go vegan

Yes, Meatless Mondays are a terrific start. But this year, try adding Tuesday. And Wednesday. Et cetera. A University of Oxford study concluded that cutting out meat and dairy could reduce your carbon footprint by 73%. “A vegan diet is probably the single biggest way to reduce your impact on planet Earth, not just greenhouse gases, but global acidification, eutrophication, land use and water use,” said lead author Joseph Poore, as reported by The Independent.

Boycott new

One way to stop supporting the constant addition to more junk in the waste stream is to boycott buying anything new (excluding food, prescriptions or emergency items). Perhaps you already enjoy thrifting and flea markets. If so, committing to buying nothing new might be a fun challenge. Make 2021 your year of browsing the free libraries, finding your new look at a garage sale and swapping useful items with other folks in your neighborhood.

Set up regular donations to environmental organizations

Just about every organization needs your help right now. Whether you prefer whales or bats, oceans or rivers, an environmental charity exists that would greatly appreciate your recurring donation, even if it’s just five bucks a month.

Control your food waste

The U.S. is one of the top countries for food waste in the world, tossing almost 40 million tons annually. Most of this food goes to landfills. In fact, food waste is the second-largest component of the average American landfill behind paper. This year, commit to only buy what you’ll eat and to eat what you buy. If you don’t already compost, get yourself a compost bin and throw in all your banana peels, coffee grounds, etc.

Get political

On the most basic level, vote. Beyond that, support causes you believe in by writing letters to your politicians or boycotting companies that are contributing to the global climate crisis. Attend town hall meetings with your local or state representatives. If you have the time, energy, resources and moxie, run for office.
