Co2 Extension is a Chrome add-on that provides users with insights into the environmental impact of their purchases on Amazon. By displaying the amount of CO2 emitted during the production and delivery of each product, this extension offers a unique perspective on the sustainability of shopping habits. Users can now make informed decisions based on real data, rather than relying on guesswork.

This tool goes beyond just awareness; it empowers users to understand their actual environmental footprint and prompts them to make conscious changes towards a more eco-friendly lifestyle. Co2 Extension aims to enhance carbon footprint calculations and is working towards integrating this feature directly into Amazon's website for wider accessibility.
