evidence: The global fashion industry is a large contributor to the climate crisis and reducing its impact is a necessity like any other. The industry belches out 1.2 billion tonnes of CO2 equivalent per year, more emissions than the shipping and aviation industries combined! And a 2021 report from the World Economic Forum identified fashion, and its supply chain, as the planet’s third largest polluter (after food and construction), releasing 5% of the world’s greenhouse gas emissions. So the fashion industry’s impact on climate change is titanic, but where are these emissions coming from? To find out you have to look along the supply chain. The supply chain is a set of connections that winds its way backward from your wardrobe through to retail, to transport and shipping, to production and processing, right back to the beginning of the line: to the raw materials, such as cotton and polyester, from which our clothes are made. By looking at the supply chain, we can separate each sector by its reliance on coal, oil, and gas: the fossil fuels that principally cause climate change. [...] Protecting the atmosphere and curbing the fashion industry’s impact on climate change involves everyone, producer and consumer alike.
