Nearly 40 percent of businesses globally have already experienced “detrimental” effects related to water security, including disruptions caused by drought and other shortages, flooding, poor quality, and increased prices, according to a new report. In a survey of companies from 25 nations, more than half responded that risks to their business are “current or near term,” an indication that the strain on global waters supplies is already being felt worldwide. The survey was commissioned by the UK nonprofit Carbon Disclosure Project, which produces annual reports on corporate responses to carbon emissions for investors. According to the survey, 67 percent of respondents are already addressing water security at the board or executive committee level; 89 percent have developed water policies; and 60 percent have established water-related performance targets. The sectors reporting the highest water security risk include food, beverage, tobacco, metals, and mining. Chemical, technology, and communications companies are least exposed to risk.
