Many countries are focusing on sustainability and how they can work to prevent global warming. Sustainable fashion is one option that can make a substantial impact. In 2018, the fashion industry accounted for 2.1 billion metric tons of greenhouse gas (GHG) emissions, which is equivalent to the entire economies of France, Germany, and the United Kingdom combined. The responsibility for change is falling on manufacturers, brands, consumers, and policymakers. As the apparel retail market continues to grow, the need for sustainable fashion and sustainable shopping behaviors becomes more essential to reach the 1.5-degree pathway. Japan, Singapore, and the United Kingdom are just a few countries trying to lead the way for sustainability in the fashion industry.
