Actor and director Ed Begley Jr. knows a thing or two about living the green life. His Platinum LEED-certified Los Angeles home is powered by solar energy, and he’s won awards for his environmental work from groups such as the California League of Conservation Voters and the Natural Resources Defense Council.

SafeBee recently asked him for his advice on small changes we can make in our daily lives that will have a big impact on the environment. If one of your New Year’s resolutions was to be greener this year, here are four ways to achieve that goal, courtesy of one of the greenest celebrities around.

1. Ride your bike if weather and your fitness permits. By riding a bike instead of driving a car, you’re not burning non-renewable fossil fuels, you’re not producing air pollution and you’re not adding to congested roadways. Not to mention — it’s good exercise.

“The U.S. Census estimates that about half of all Americans live within five miles of their workplace. Those who decided to bike those five miles every day rather than driving an average car could reduce total household emissions by six percent,” National Geographic reports.

Begley practices what he preaches here. He even rides his bike to major Hollywood award shows, including the 2015 Academy Awards.

2. Take public transportation if it’s available near you. By riding a bus or subway with other commuters, you’re conserving gas and energy and reducing your carbon footprint, according to the American Public Transportation Association (APTA). In fact, if you switched from driving a 20-mile roundtrip commute to using public transit, your annual carbon dioxide emissions will decrease by 4,800 pounds per year, APTA says. That’s equal to a 10 percent reduction in a two-car household’s carbon footprint.

Plus, you’ll get a little exercise walking to and from the bus stop or subway station.

3. Eat more plant-based foods. A panel of experts tasked with developing recommendations for the 2015 Dietary Guidelines for Americans noted that animal agriculture produces greater greenhouse gas emissions than plant agriculture. In addition, producing meat requires more water, energy and land than growing most vegetables and fruits.

4. Change your lighting. In this video, Begley suggests families use energy-efficient light bulbs for their homes as a cost-effective way to help the environment. Compact fluorescent lamps (CFLs) and light emitting diodes (LEDs) typically use about 25 to 80 percent less energy than traditional incandescent bulbs and can last up to 25 times longer, according to Energy.gov.
