Looking behind the curtains
of a t-shirt, coffee and chocolate
The manufacturing process of a t-shirt is energy intensive, however, most water is consumed to produce the cotton for the t-shirt. So don't focus on the carbon footprint alone. Global warming is just one impact assessment category. It is vital to consider other environmental aspects such as water and land use, material requirements and pollution as well to understand the full spectrum of impacts and potential trade-offs.
Only looking at the production stage of your product is deceptive. Your products's upstream supply chain, its use phase and its end-of-life also have environmental impacts. The most impactful stage of your supply chain might come as a surprise.
