About Giki Zero

Learn what you can do about climate change

Three quarters of global greenhouse gas emissions come from people so to really cut carbon everyone needs to be involved.

The challenge is that many people don’t know what to do or where they can have the biggest impact. Giki Zero helps with both.

How does Giki Zero work?

With a few simple questions we can estimate your carbon footprint. You can then choose from over 150 steps to find ways to reduce it. It’s free and super easy to use.

Personalise your carbon footprint

Giki has a detailed, science based, carbon calculator which is still easy and fun to use! Enter as much, or as little, information as you want. The more you put in, the more personalised your estimate and we cover everything from home, food and travel, to pets, financial services, clothes and lots more.

Find the right steps for your lifestyle and budget

Giki is used by everyone from sustainability starters to green Pros. That’s because we’ve got steps covering everything from quick wins to Planet Savers. Use our handy checklist to help you complete your steps. Every step comes with lots of useful extra information to help you along the way.
