Fashion. Each year, more than 100 billion pieces of clothing are produced worldwide, with 65 % of them ending up in landfills within 12 months. The fashion industry is responsible for 8 to 10 % of global carbon emissions, which is more than aviation and shipping combined. How can we make our wardrobe more sustainable? You can start by buying clothes second-hand, from thrift stores or sites like eBay, Vinted or Depop, or by renting them instead of buying new items.  Cutting back on washing can also help further reduce the carbon footprint of your wardrobe and reduce the number of microplastics that end up in our waterways. Finally, it is important to think about what we do with our clothes at the end of their life. Instead of throwing clothes in landfills, a better approach is to give them to friends, sell them online, or take them to thrift stores. There are of course many other changes you can make, from relatively small ones such as upgrading your light bulbs to more efficient LEDs (0.1 tonnes of CO2e per year) to very large life decisions such as deciding to have one less child (58.6 tons of CO2e per year for someone in a developed country, according to one study). Many people may choose to participate in one form or another of climate activism. The good news is that many of these changes are not only good for the climate, but also for your health and well-being. And on a larger scale, by helping to limit climate change, these small actions can also contribute to improving gender equality, racial equality and biodiversity.
