No more sitting behind an event table with no one speaking to you all day

An attention grabber

Grabs passing trade including sustainability newbies and even those who at first might not care

You are visible

People will see you from at least 25 metres across the room at events

Mind-blowing for players

Who’s going to ignore a life-size banana talking to you!? (the game wall is 2m wide x 2.2m high)

Prepare to be busy

A busy stall draws more people to you and you WILL be busy

Use the spillover effect

It lures people into signing up to your other sustainability activities

What the players say

The stealth bomb for delivering climate science

In the BIG Carbon Footprint Game you take 5 paired items and in each pair the player has to guess which one has the higher carbon footprint.

This might look like a simple comparison card game but it’s way more that that. It’s a stealth bomb for delivering climate science! Your people have fun playing the game and absorb new climate facts as they go. For many people this is the gateway learning experience so they can no longer ignore the climate emergency and are ready to engage with your plans. The BIG Carbon Footprint Game gives power back to the people and makes them see THEY can BE the change in the world they now want to see.

Every action matters in our climate changing world and the Carbon Footprint Game opens your players hearts and minds to recognising their own impacts.

Want to play one round yourself?

Which one of these two items has the higher carbon footprint?

But don’t guess.

Consider the following:

  1. What does the supply chain look like?
  2. Where does it come from?
  3. How does it get to you?
  4. Which part has the biggest carbon footprint/ impact?

Touch the cards to flip them over.


So were we, when we started developing the game. There are many ‘not so obvious’ carbon facts out there.  If you wonder why a tank full of petrol is so much higher than the week’s food shopping of a vegetarian and which part has the biggest impact on the carbon footprint, then turn around the next card to get some explanations.

Our experience is that everybody leaves having learnt something new and most people are shocked by the things the game can show them. Many players are inspired to act on what they’ve learnt.



Touch me to get the answer

An empowering game changer

The game breaks the impacts down into digestible chunks so it’s never imposing. It’s not condescending – it is empowering. It creates critical-thinking in your players that spreads across and beyond the climate crisis so your people can understand many sustainability issues.

You might compare two food cards and their carbon impacts but the carbon conversation can flow across travel, production, water, waste and even working conditions. You can use the cards to raise other environmental and social issues – the conversation is completely down to you as the facilitator but don’t worry we will skill you up with our Carbon Academy to be the best facilitators of the game or you can rent us to do it for you. We will come to your event and facilitate the game for you.

Do you have more questions?

All of our games are for those who wish to find a different way to educate about the climate crisis and carbon footprints. You could be a primary or secondary teacher, a trainer, facilitator or environmental educator at a charity.

You don’t need to have any prior knowledge of carbon footprints to play the game with others. All you need is a willingness to learn and read the ‘How Bad are Bananas?’ book as well as some facilitation experience or confidence (if you’re low on experience or confidence, our games have been shown to help facilitators develop both).

Delivering messages, teaching new things and trying to change behaviours is a continuous battle.

But, what if it didn’t need to be…

The Small Carbon Footprint game brings the ‘wow’ back into learning and excitement into engaging with people. The game encourages and creates a connection with your learners that far too often other learning methods ignore.

By having cards in the game that represent everyday items that everyone has consumed (food, shoes, clothes, tech, cars) learners can identify and are able to resonate with the messages the game teaches. The critical thinking learners can develop has the ability (in some of them) to provide the first gateway into the world of sustainability and climate action. Everybody leaves having learnt something new and most people are shocked by the things the game can show them and many wish to go on to act on what they’ve learnt.

The game is straightforward and easy to use and the Carbon Academy provides the facilitation training and learning necessary to play with your users straight away and we feel there is no better way for you to perfect your facilitation skills than play with learners straight away.

There is no other game like this on the market.

Sector leading research
Mike’s book ‘How Bad are Bananas?’ underpins all data used in the game and is the most up-to-date compendium of carbon footprint research in the UK.

Expert facilitators
We have our 6 years of game facilitation experience to share with you and when your facilitation is right, the game will ‘wow’ your audiences into engaging with your sustainability or climate action initiatives.

Accessible learning style
Our games are unique because they help the user to personally identify with the issues rather than coming to the learning out of context. This style of learning makes for a more accessible and fun approach which has a lasting effect on the learner.

Did you find this FAQ helpful?

Research has shown that children can recall far better details of games they have played than most formal learning they receive. Using games as a way of learning works very effectively as they engage players in multiple different ways simultaneously.

As Kolb (1984) outlined in his theory of experiential learning, we all learn in multiple different ways (active learning, planning, theorising, reflection) and games are very good at engaging multiple learning capacities simultaneously. Marketeers know that we love receiving prizes, recognition, badges and rewards for doing (or not doing!) stuff. This trend for gamification has taken off and is now all around us!

The only way our game is different is that it’s a game NOT JUST gamified learning. By building on societies love of games, we aim to create even more intrinsic motivation for people to engage with the game than just the extrinsic motivation to collect rewards.

Our original and highly eye-catching BIG carbon footprint game is the best way to start carbon conversations with anybody! It’s a carbon conversation tool, a critical thinking developer, and a fun game all delivered in an easily digestible format. The 4m wide by 3m high game wall is supported by infographics that magnetise your audience towards you for engagement! There is no escape! LOL! The large print ‘How Bad are Bananas?’ side caps intrigue some players to come and find out the answer to the question (Loughborough University students were gutted bananas might be ‘bad’! But are they?! That’d be telling!).

Did you find this FAQ helpful?

From the selected pack of cards, players are invited to compare 5 paired items, and in each pair guess which item has the higher carbon footprint. Sometimes it’s easy (an eco-child vs an average child) sometimes it’s pretty tricky (the papertowel vs. the hand-dryer) and sometimes it can be a very random pairing (a pair of jeans vs. 1 kg of organic, vine-grown cherry tomatoes from the UK).

The comparisons are designed to get players thinking about where items come from, what makes up their carbon footprint and encourages them to use their own experiences of the world to reach an answer. The skill is in the delivery of the facilitator, and we have ALL the support you might need (the Carbon Academy AND Carbon Literacy courses) to become a GREAT facilitator of the game.

Did you find this FAQ helpful?

With every game you buy you will receive 1x user licence to access ‘The Carbon Academy’ which helps you to learn at your own pace how to confidently and effectively facilitate the game with your own players. You will need 3 hours+ to work through The Carbon Academy although we signpost you to lots of further reading and learning to help you be an even better game facilitator.

Whilst the Carbon Academy, helps to set the scene on the climate crisis, the main focus is on helping you to become a confident and skilled facilitator of the BIG Carbon Footprint Game.

With every copy of the BIG Carbon Footprint game purchased, you receive:

  • 80 durable playing cards printed on 100% recycled and recyclable board and provided in a snug-fitting box.
  • The full 3m x 4m game playing wall (full colour) in cardboard carry cases and the connecting parts to put it all together (including instructions for putting it up).
  • 1x ‘How Bad are Bananas?’ The Carbon Footprint of Everything book (2020 edition) by Prof Mike Berners-Lee.
  • 1x user licences for ‘The Carbon Academy’ to give you online training to teach you how to play with others for best effect.
  • A recommended optional day of face-to-face or online facilitation training to support you in delivering the game.

The BIG carbon footprint game is perfect for events, outreach work and your everyday carbon literacy education. Unlike the smaller games, the original game is difficult to miss when it pops up in different places! Its time for us to educate everyone on the climate crisis and this is the perfect tool for doing just that!

Did you find this FAQ helpful?

Fun, eye-catching, unforgettable! This is the only behaviour changing tool that puts ‘fun’ as its main objective. Other climate learning can often create a disconnect between learning and individuals and their actions but the BIG Carbon Footprint game firmly connects actions, choices and behaviours together to empower individuals to want to make impactful choices and take action.

A giant eye-catching design, you’re not going to miss an enormous yellow game shouting ‘How Bad are Bananas?’ from the other side of the room and therefore won’t forget it or its lessons in a hurry!

Did you find this FAQ helpful?

We have a sliding scale of costs of the big game for different clients. Our work with corporates helps us to give back to the schools and charities sector with our variable pricing. So you know you’re giving something back as a corporate buyer of the game.

Approach us to get a quote, which is tailored to your needs.

Don’t forget you can rent our BIG game too (with a facilitator) if you’d like us to show up with a copy of the game and play with your different audiences for just a day or two. Just get in touch and we’ll work a price out for you.

Did you find this FAQ helpful?

Yes you can, but not via the shop – please talk to us about your needs and we can work out shipping costs first and quote you with something more accurate.

Did you find this FAQ helpful?

Yes! Although we will need you to cover appropriate travel and time expenses if we have to travel a long way to get to you and just for the record we travel VERY slowly (i.e. we avoid flying)!

Did you find this FAQ helpful?

If you rent the BIG game for a day, you get a trained and experienced facilitator as part of the price and we can work together on the best way of using the time for the greatest impact with your learners or for your event.

Did you find this FAQ helpful?

We rent our BIG game to clients who have green/ environment/ climate days or events they are celebrating or promoting. We can adapt what we do to train up some of your stakeholders in a workshop in the morning and then get them to play with other people later in the day to maximise the impact of the game.

We can set-up a series of workshops so you can have your staff or stakeholders trained up in groups for an hour for in-depth carbon learning. Feedback on this format so far is “we want more!”. Add in a competitive element and have a play-off of your top two teams at the end of the day. Throw in some copies of the How Bad are Bananas? books and you have ethical prizes to give away to the winners!

Launch your policies, strategies and plans or engagement programmes with a fun and engaging activity

We cover staff training days, Christmas parties and away days – ask us for more details dependent on your own specific needs and numbers of participants

Did you find this FAQ helpful?

We have a sliding scale of costs for rentals of the big game for different clients. Our work with corporates helps us to give back to the schools and charities sector with our variable pricing. So you know you’re giving something back as a business rental of the game.

Did you find this FAQ helpful?

Maybe! We don’t currently offer a list price for physical rental of the game outside of England, Scotland or Wales. You would have to pay for travel time and the costs to travel without flying if you’d like us to be at your event. Just drop us a query to our main [email protected] address and we’ll provide a quote. It is possible to deliver virtual rentals of the game but we still recommend this is done face-to-face for best effect.

Did you find this FAQ helpful?

If you like our BIG carbon footprint game for your outreach and engagement activities, you might like to add in a set of our small games. This means you can take a copy with you wherever you go, just sling a copy in a bag and play in meetings (face-to-face and online!).

If you want to learn more about climate change to support your facilitation of the game then throw in a voucher for a 1 day face-to-face or an online Carbon Literacy course to help develop your confidence.

Did you find this FAQ helpful?

Unfortunately, yes it is possible to play the game badly and that’s why we put the Carbon Academy together to help you learn the best techniques for playing the game with others. We do find that there is no other learning like having a go at playing with others.

Carbon Academy

We’re not currently selling access to The Carbon Academy separately from buying games. The Academy has been set up specifically to support those who are using the Carbon Footprint games to educate others.

Did you find this FAQ helpful?

The Carbon Academy is our online ‘bananas’ learning platform. This gives you all the background info on how to play your carbon footprint game with others – i.e. it gives you ALL the relevant training to become a GREAT facilitator of the game.

Did you find this FAQ helpful?

You get free access (1 license) to the Academy when you buy any of our small or big games. You currently can’t buy access to the Academy without buying a game although talk to us if you have games already and would like to have more logins to access the Academy.

Did you find this FAQ helpful?

There are 6 chapters in the Academy (although Chapters 1 and 2 set the scene by telling you a bit about us and a bit about the Academy).

There are then 4 core learning chapters in the Academy:

  • Chapter 3: Embracing the Climate Emergency
  • Chapter 4: Getting acquainted with your game
  • Chapter 5: Growing facilitation skills
  • Chapter 6: What’s next? (further resources, evaluation and certificate)
Did you find this FAQ helpful?

You will be tested in the final Chapter of the Academy to check you have retained sufficient knowledge of how to play the game.

If you’ve never facilitated before, we find that playing the game helps you to develop more facilitation skills. Playing the game becomes easier to do and better quality (in terms of learning) the more you do it. Back at Bananas HQ, we find even now that we have completely different conversations with our players and we’ve facilitated for over 6 years and have played with thousands of different people.

Did you find this FAQ helpful?

Yes – you will be able to download a certificate once you’ve finished working your way through the Carbon Academy.

Did you find this FAQ helpful?

To maintain some quality control around learning, we obviously recommend you work your way quickly through the basic Carbon Academy material – a lot of it is in video format so it is a bit easier to get through quickly.

You should then choose a number of cards you’d like to compare well and read the relevant sections of the ‘How Bad are Bananas?’ (2020 version) book (copies available with all versions of the game sold and more available to buy in sets of 5 if you need them).

Did you find this FAQ helpful?

Once you’ve bought a game, the Academy will be open for you to use from that point on, so you can return to the Academy if you’d like to brush up on your skills or help others to learn how to facilitate too.

Did you find this FAQ helpful?

The Carbon Academy will explain everything you need to know in order to facilitate the game!

Did you find this FAQ helpful?

It is possible to share your login details with others in your organisation who wish to learn how to facilitate the game. If they would prefer their own login then please contact us to arrange this.

Did you find this FAQ helpful?

Nope. We think anyone can learn how to become a great facilitator of the game. You don’t have to be a teacher. Having teaching skills or experience may give you a bit more confidence but everyone needs to read the book and learn the shortcuts and tips to playing a great game and delivering the right messages.

Did you find this FAQ helpful?

You need to use generic facilitation skills to play the game well with players. These include but are not limited to: listening skills, setting the scene, defining the carbon footprints, asking questions, giving players space to learn for themselves, not dominating the conversation but also providing key facts and useful tips as players go through the game.

Did you find this FAQ helpful?

Unfortunately, yes it is possible to play the game badly and that’s why we put the Carbon Academy together to help you learn the best techniques for playing the game with others. We do find that there is no other learning like having a go at playing with others.

Did you find this FAQ helpful?

No. The Carbon Literacy course must be delivered over 8 hours before you can be certified as Carbon Literate.

Our Carbon Academy focuses on teaching you specifically how to use your new games and play in a way that should be most impactful with your stakeholders or learners as well as giving you a bit of background on the climate science.

The Carbon Literacy course, will use the carbon footprint games as part of your learning and will give you an overview of how playing the game is an effective way of delivering carbon literacy. The Carbon Literacy courses are longer pieces of learning – you also get the background on climate science delivered through a group exercise, as well as giving you space to reflect on your own climate action plans. Find out more about the Carbon Literacy courses here.
