Besides using eco-friendly laundry products – including detergents, fabric softeners, and dryer sheets – be mindful of the energy washers and dryers expend. Switching from washing your garments in warm water to cold will cut back on 90% of the energy used by your washer. A dryer leaves quite a carbon footprint: the average household runs a dryer 200 times a year, producing half a ton of CO2 emissions. Consider air drying your clothes on a drying rack instead.
