Water is a precious and indispensable resource that humans rely on every day. To avoid environmental pollution and make full use of water resources, sewage treatment plants are built to recycle water and deal with harmful materials.

According to the China Association of Environmental Protection Industry, the sewage treatment industry accounts for about 1 percent of the total carbon emissions in China, which is generated by high energy consumption devices and heavy use of drugs. In the context of realizing the carbon peak emissions and neutrality goals, it is significant to promote scientific and high-efficient technologies to reduce carbon emissions and promote the green, low-carbon development of eco- friendly industry.

The first association standard, T/CAEPI 49-2022, Technical specification for low-carbon operation evaluation of sewage treatment plant, was published on June 6 by China Association of Environmental Protection Industry. It officially came into effect on July 1.
