In honor of St. Patrick's Day, we gathered tips on how to celebrate your Irish side in the greenest of ways.

1. Bike to the bar.

The Irish, more than any other national group, have managed to get their bars into nearly every city on Earth. When you head out for the pub this year, join the growing movement of bike-only commuters and cycle there instead of driving to slash your greenhouse-gas emissions. However, remember to  limit your intake; a BUI can be serious business. If your regular bar is too far to bike, try someplace new: Use this app to locate the closest bar with Guinness on tap. Cheers!

2. Buy organic, local corned beef.

Although not traditional Irish cuisine, corned beef has become a St. Patrick’s Day staple for North Americans. If you plan to serve it up — with cabbage, of course — buy your beef from an organic producer who practices sustainable ranching methods. You can also visit your local farmers' market to find beef raised in your area; often, eating local is even ecofriendlier than eating organic.

3. Dress in green clothes you already own.

On St. Patrick’s Day, wearing green is mandatory if you want to avoid pinches from eager fingers. But the eco-friendliest way to dress green is to wear what you already own: Less consumption means less waste, and even a small showing of the color (socks?) gets you into the pinch-free zone. If you must shop for a verdant hue, support one of the many fashion companies who manufacture with the planet in mind. Not surprisingly, many responsibly minded clothiers favor the color green, or even emphasize it, so it shouldn’t take the luck of the Irish to find what you need.

4. Drink this ecofriendly Irish coffee.

If cloudy March weather has you shivering, stay warm today with a nice, warm Irish coffee. A well-balanced blend of your favorite eco-friendly coffee and whiskey is a proper way to kick off St. Paddie’s Day. If coffee’s not your thing, pour yourself a pint o'Guinness, which now gets its signature head from a biodegradable cellulose “widget,” so the whole can is recyclable.
