What are we screening?

The Do The Math documentary is a 42-minute film about the rising movement in the United States to change the terrifying maths of the climate crisis and challenge the fossil fuel industry. While it is set in the United States, the maths the film outlines apply globally -- making it important for all of us to watch. It is in English with the option of subtitles in French, German, Portuguese or Spanish.

When can we host a screening?

Whenever you want -- try to host it at a time when you think lots of people can join you.

Who will be hosting the screening?

ANYONE -- students, teachers, parents. You don't need to have ever done anything like this before. 

Why host a screening?

Film is a great tool for organising and mobilising our movement for action. By hosting this screening and discussion, the film should spark dialogue and action in communities across the world. We must understand the terrifying maths of global warming, promote just solutions and fight dirty fossil fuel projects.

Where do I sign up to Host a Screening?

On this page -- fill out the form and you'll be ready to go.

I just signed up to host a screening, what next?

You should have been emailed a confirmation from and direct contact information with our support staff to answer further questions to help make your screening a success, in addition to links to watch/download the film. After you sign up, you can also use your "host tools" to communicate with people who RSVP. 

I'm anxious about hosting a screening – I've never done this before.

Hosting a screening is very simple -- all you need to do is register your event, make sure you've got the equipment you need to screen the movie, reserve a couple of hours, and spread the word! You can always co-host a screening and invite local leaders to co-lead the discussion after the film if you wish.

I can no longer host my screening, but I have attendees that have already signed up?

Let us know by contacting [email protected] -- we can try to recruit another event host in your area, and let your attendees know about the change of plans. 

What is the schedule? How much time should we plan for?

The whole event should take about 1.5 hours. Here's a sample schedule:

19:00: Event starts, allow approximately 10 minutes for people to arrive.

19:10: Short introduction to the film. 

19:15:  Start the movie! It's 42 minutes long. 

20:00: Discussion of the movie for 30 minutes.

Whom should I invite?

Family, friends, neighbours — anyone you feel should see the film. If you want to expand your reach, consider inviting representatives from diverse community groups so numerous points of view are included and a well-rounded conversation can take place.

How do I find a venue or place to screen the film?

We encourage bigger groups to get together to screen the film if possible – and that means bigger places to congregate.  Possible venues include schools, universities, religious institutions and community centres. Be proactive. Think Big. Any place people can get together, watch and discuss can be a screening venue. If you don't want to deal with any logistics, you can also host a screening at your home.

How do I watch the movie online or download a video file?
We'll email you a Youtube link to the movie ahead of the screening date, or you can download the video file (low, medium and high resolution options) after filling out this short form here. Note that you'll need a way to hook up your computer to a TV or projector to play the file on a larger screen.

How do we lead the discussion?

The film will inspire conversation on its own, but choosing one person who will moderate or facilitate discussion will help to focus the group and clearly identify actions that people can easily engage in. It's a good idea to designate one person to take notes and collect all attendees’ contact information so that you can continue to communicate with one another after the screening.

We recommend that before the discussion ends, you offer your guests a list of easy, specific actions that they can take within your community -- we'll email you more information in your host's packet after you register your event.

Does the movie only focus on Bill McKibben?
While Bill McKibben is the central character of the movie and provides a compelling personal narrative, the movie tells a movement-wide story, and features a diverse range of friends and allies in the United States. 

How do I create a playable DVD?
If you need a playable DVD, you can download the video file and then burn it to create a playable disc using these programs:

How can I edit my event or check on RSVPs?
To edit your event or check on RSVPs, you need to use your "Host Tools." 

To access the Host Tools, you have two options:

1) You can click on the link that is in the confirmation mail  (subject line:'Confirm your "The Do the Math Movie! Screenings and House Parties" event') we sent you.

2) You can also login to your Host Tools at If you've never logged in before, you'll need to click the link on that page to to set a password.

Can I have a private screening?
The best way to make sure your screening isn't open to the public is to select the "Make your event private" box when you register a screening. Private Screenings won’t be displayed on our map or publicly searchable -- but you can distribute the link to others if you want to let them RSVP.

I tried to register using the online form but got an error -- what should I do?
Sorry about that -- sometimes our system has a hard time with certain addresses. You can fill out our backup backup form and we can register your event manually.
