Earth Hour

tcm:6-6622_Earth Hour LogoThe City of Boston invites all residents and businesses to participate in Earth Hour to raise awareness about climate change. Organized by the World Wildlife Fund, Earth Hour will take place on Saturday, March 29th, 2014 from 8:30 to 9:30 PM and asks participants to extinguish all non-essential lighting during this one hour. Boston will be among over 7,000 cities and towns world-wide that have pledged to shut off lights for Earth Hour; we ask all residents and business to participate by shutting off all non-essential lighting for Earth Hour.

Help Us Celebrate Earth Hour

Earth Hour is a great opportunity for all Boston residents to join city officials and other civic and business leaders in demonstrating how we are working together to reduce the risk of climate change and to showcase your individual contributions to the larger solution.

You can help us spread the word by inviting your friends and neighbors to participate in Earth Hour by sending them an email. Use this opportunity to start a dialogue with your friends and neighbors and discuss why finding a solution to climate change is important to you.

This year, we are also asking Bostonians to share Earth Day photos and stories with us on Facebook and Twitter via #EarthDayBos so we can compile them and show how committed Boston is to this cause!

What Do I Have to Do for Earth Hour?

Earth Hour participants are asked to turn off all non-essential lighting for their buildings, especially architectural lighting, from 8:30 to 9:30 pm on Saturday, March 29th 2014.  Any lighting that is essential for active use or related to public safety, such as street and emergency lighting, should be kept on.  If any lights need to remain on for additional functions within the building, we ask that the shades be drawn if possible.
