Here’s what we know.

The transportation sector is the largest single source of California’s greenhouse gas emissions, at nearly 40% of the state’s total emissions.

Almost 90% of transportation emissions in California derived from on-road sources.

31% of vehicle trips in Napa County are less than 2 miles, and 63% are less than 5 miles – which are within reasonable biking distance.

If Napa County residents shifted just some of their short trips (<5 miles) to biking, we would make noticeable progress toward meeting environmental goals and cleaner air. You can read the latest on reducing carbon emissions via bike commuting here.

Take NCBC’s Earth Day Challenge!

Step 1) Pledge to ride your bike during Bike Month (May) through our Pledge to Ride form. In the “Why You Ride” question, make sure to mention the Earth Day challenge! You’ll be automatically entered into our weekly prize drawings for great bike-themed prizes, and you’ll be entered to win a special Earth Day Challenge prize.

Step 2) Use the Bike2it! tool, developed by our friends over at Sonoma County Bicycle Coalition, to find destinations within a 2-mile radius of your house, office, or school. If you’re feeling ambitious, make that radius even bigger!

Step 3) Pick at least one destination you normally drive to and switch that trip to biking for the month of May, whether you go there once a day or once a week. The more trips you shift to bike, the smaller your carbon footprint.

Step 4) Use Omni’s Car vs. Bike Calculator to calculate your CO2 reduction for the month of May. Remember: only calculate for bike trips that are replacing car trips.

Check out our Bike Month page for resources, events, and other programs going on during the month of May!

Contest Rules:

Must be a Napa County resident to be eligible for a prize. Prize drawing for the Earth Day Challenge prize will be selected from Pledge to Ride submissions sent in between April 1, 2021 and April 26, 2021.
