Water stress Household water scarcity caused by climate change is another physical risk, which is exacerbated by population growth and urbanisation. During periods of drought consumers may reduce their use of certain products including laundry detergents, shampoos and conditioners, and toilet cleaners as they are unable to access water to use them or experience declining water quality which limits their enjoyment and/or efficacy. While the overall impact of water stress on our sales, from both policy and physical impacts, was not found to be significant in our scenario analysis at a global level within the 2030 time horizon evaluated, the impacts we see in the short term tend to be more local.
