Water performance index
| Quantitative | Qualitative | |||
|---|---|---|---|---|
| Water use (wu) (0–4 score) | Wastewater discharge (wd) (0–4 score) | Wastewater reuse (wr) (0–4 score) | Water-related reward (wrr) (0–4 score) | Water-related punishment (wrp) (0–4 score) |
| Equal to 1 if water consumption is lower than the previous year and 0 if otherwise | Equal to 1 if wastewater discharge is lower than the previous year and 0 if otherwise | 100% ≥ wr >75%: 4 score | International level rewards: 4 score | Cancellation of business license/market Ban: 4 score |
| Equal to 1 if (water consumption/current year’s operating income) is lower than the previous year and 0 if otherwise | Equal to 1 if (displacement/total sales revenue for the year) is lower than the previous year and 0 if otherwise | 75% ≥ wr >50%: 3 score | National level awards: 3 score | Fine: 3 score |
| Equal to 1 if water usage is less than the median water usage in the industry and 0 if otherwise | Equal to 1 if displacement is less than the median displacement in the industry and 0 if otherwise | 50% ≥ wr > 25%: 2 score | Provincial level rewards: 2 score | Warning/condemnation: 2 score |
| Equal to 1 if (water consumption/total sales revenue for the year) is lower than the median of the industry’s (water consumption/total sales revenue for the year) and 0 if otherwise | Equal to 1 if (displacement volume/total sales revenue for the year) is lower than the median of the industry’s (displacement volume/total sales revenue for the year) and 0 if otherwise | 25% ≥ wr > 0%: 1 score | City level and below rewards: 1 score | Criticize: 1 score |

Note(s): The final score for water performance = (wu + wd + wr + wrr-wrp)/water risk, where wu denotes water use, wd denotes wastewater discharge, wr denotes wastewater reuse, wrr denotes water-related reward, wrp denotes water-related punishment and water risk denotes the water risk index of the basin to which the company’s actual geographic location belongs
