According to forecasts, the world’s population will grow to 9.1 billion by 2050, water demand will increase 55 percent from current levels, and 40 percent of the world’s’ population is therefore expected to suffer water shortages*. Water is used in painting and other car manufacturing processes, making it imperative to reduce impacts on the water environment as much as possible. We have two main strategies to adopt our challenge; thoroughly reducing the amount of water used, and comprehensive water purification and returning it to the Earth.
Toyota has pursued various effective initiatives, such as collecting rainwater to reduce the amount of industrial water usage, raising the water recycling rate through filtering, recycling wastewater for reuse, and returning clean water to the local environment. As the local water environment differs depending on the region, moving forward, we intend to expand our water environment initiatives around the world, taking the local needs into account.
To reduce water usage in our production activities, we have been working to introduce innovative technologies alongside planned upgrades to our production lines, and to conduct regular activities to reduce water consumption. In FY2016, total water consumption at Toyota Motor Corporation (TMC) was 10.7 million m3 (down 1.9 percent year on year) and water consumption per unit produced was 4.3 m3 (down 8.0 percent year on year). Globally, Toyota is steadily implementing measures to gradually conserve water usage consumption depending on the water environment in each country and region. In particular, we are encouraging water recycling in those regions with scarce water resources. In FY2016, our water consumption totaled 31.3 million m3 (up 7.0 percent year on year) and water consumption per unit produced was 3.0 m3 (up 1.4 percent year on year).
