Carbon footprint
We calculate the carbon footprint of both the brand and the product to create the combined rating for the product.
Sustainability Factors
We take into consideration various factors, such as materials, CO2 intensity, waste management, labor practices, transparency of the brand, electricity usage and renewable energy sources, and warranty services.
