Whether you’re a Twitter addict or a fanatical instagrammer, please tell everyone about Clean Air Day using the hashtag #CleanAirDay and let’s get millions of people talking about it.

We’ve set up an Clean Air Day event on Facebook to promote the day too. So invite your friends and family, and ask your workmates to join in. Hey, tell your Gran about it – the more the merrier.

And don’t forget to tell us what you’re planning to do on 21 June.
