Through this collaboration, we shaped Karbon-X into a functional and intuitive platform. The design emphasized simplicity and transparency, allowing users to choose carbon offset plans that matched their goals, ranging from 4,000 kg to 12,000 kg of CO₂ per year per subscription. Each plan contributed to impactful projects such as reforestation in Bolivia and ocean deacidification in the UK, creating a direct link between users' actions and environmental impact.
