Invest in climate education with us

Climate action is essential – but let's be honest: numbers, statistics and debates about what to give up are often dry and frustrating. That's exactly what we want to change!

With Sinner or Saviour, we have developed a strategic, educational and, above all, entertaining card game that makes climate education accessible in a playful way. You discover which everyday decisions influence your carbon footprint – and you might even leave the game as a climate expert.

It's ready to print but we can't produce it without you.

Support our campaign on Startnext and help make climate education more accessible, interactive and entertaining!

Fun, strategy, and CO2 footprints

Sinner or Savoiur turns learning about CO₂ and the climate crisis into a fun and eye-opening experience with friends.

Climate education doesn't have to feel like homework. Through strategic play, you can learn about CO2 footprints and the climate crisis with friends and finish with actionable and affirming insights to reduce your footprint.

Gameplay

You can play with 3-6 people within 45 mins. The cards show CO₂ pollution in the areas of energy, mobility, nutrition and consumption. The lower the pollution, the better the card.

Players estimate their tricks per round and manage a climate budget of 150 points. The player with the most climate points at the end wins.
