Lights Out London

This year, Bird Friendly London is launching a grassroots city-wide initiative to reduce light pollution in London by encouraging businesses to turn off unneeded lights after dark during the week of May 13-19, 2022. This coincides with World Migratory Bird Day on May 14, with this year’s theme dedicated to reducing light pollution.

Participating is easy - just complete these three steps:

1) Let us know! If you are a business or property manager in London or surrounding area, or if you live in a large residential building that will be participating, please fill out this form indicating that you'll be turning out some or all of your lights after dark. We would be thrilled to acknowledge you among participating partners in London.

2) Let people at your organization or in your community know about this initiative. We suggest circulating an email to people who should know about this in the first week of May and/or posting notices on the premises to remind building users to turn off lights at the end of each work day, or to close curtains or blinds if bright lights will be left on inside. You may want to print or circulate this template poster, such as by posting it near an elevator or main entrance.

3) Please share word of your participation on social media, to help raise awareness of light pollution and your organization's commitment to address it. We suggest using the hashtag #lightsoutlondon or tagging us at @BirdFriendlyLdn and @LondonEnviroNet on Facebook, Twitter or Instagram.
