On Saturday 19 September 2026, buildings, landmarks, and homes around the world will light up green to raise awareness of mitochondrial disease. From famous monuments to quiet neighbourhoods, this global event brings visibility to a condition that affects thousands but is still widely misunderstood.
Light Up for Mito is more than just a beautiful display. It is a collective moment of solidarity. Each green light represents a step toward recognition, understanding, and change for those living with mito.
How to get involved
You don’t need a famous building to make an impact. Whether you organise a city-wide event or switch on one green bulb at home, you are part of a powerful global movement.
Light up a local landmark
Ask a nearby monument, museum, hospital, or town hall to participate. We have everything you need to make it easy, including a template invitation letter and press release that you can customise and share. A single illuminated landmark can spark media coverage, conversations, and greater awareness.
Light Up Your Home
Make a difference from your doorstep. Change your home light to green or use your smart lighting to create a glow that gets people talking. Invite neighbours to join and explain why your home has gone green for mito. Small actions lead to big awareness.
Spread the word online
Take photos and videos of any green-lit spaces and share them on social media using #LightUpForMito. Tell others why you are involved and help grow the campaign. Your story can inspire more people to join and support the cause.
Use the free toolkit
Our downloadable resources include posters, social media graphics, press materials, and step-by-step guidance to help you plan and promote your activity. Everything is ready to personalise and use in your community.
Go virtual with green
Take part from anywhere in the world by using our Light Up for Mito virtual resources. Download and use our template Zoom or Teams background, update your social media profile picture or share our digital graphics throughout the day.
Whether you're joining a meeting, attending a virtual event, or connecting with friends online, every green screen helps spark conversations and raise awareness of mitochondrial disease.
