Something really incredible is happening in Paris this December, when world leaders will gather for COP-21, a once-in-a-lifetime opportunity to forge a crucial climate agreement between nations. While they negotiate about the fate of the planet, community organizers, businesses, innovators, and citizens like you will be able to send them a message.

So, this is it: Our chance to tell world leaders that we care about the outcome of Paris. That’s why we here at GOOD are teaming up with a group of remarkable partners—from the United Nations Foundation to The City of Paris—to ensure we make the most of this historic moment.

Let’s make sure they hear our voice. Visit earthtoparis.org to find out how you can take part in this extraordinary movement. (We’ll be updating with big news very soon.) In the meantime, download this digital toolkit for easy ways to participate. Plus, join us today—and every week—for a conversation on Twitter leading up to COP-21 with the hashtag #EarthToParis:
