I will replace 3 incandescent lightbulbs with Energy Star-certified LED bulbs, saving up to $14 per fixture per year.

I will plan ahead to use paper products only made from post-consumer recycled paper for my home or office.

Contamination prevents what is recyclable from being recycled. I will research and recycle all materials that are accepted by local haulers or drop stations in my community, including electronics and metals.

Using Drawdown's Job Function Action Guide, I will learn about climate actions I can take at work.

I will enjoy 1 meatless or vegan meals each day of the challenge.

I will complete a plastics audit to see where plastics show up in my life and determine how I can reduce the use of single-use plastics.

I will practice the "5 Rs" — refuse, reduce, reuse, repurpose, and recycle — to reduce my waste more than I can with just recycling alone.

I will use smaller plates and/or serve smaller portions when dishing out food.

I will spend at least 15 minutes learning more about the energy generation potential of geothermal energy and consider investing in this technology.

I will spend at least 15 minutes learning how to differentiate between sell by, use by, and best by dates.

I will reduce the amount of paper mail that I receive by 0.11lbs (0.05kg) a day or 3.3lbs (1.6kg) a month by opting into paperless billing, ending unwanted subscriptions, and opting out of junk mail.
