3.3 Life Cycle Assessment

Life cycle assessment refers to the compilation and assessment of inputs, outputs and the potential environment impacts during the life cycle of a product system. [source: GB/T 24040-2008, Definition 3.2]

4.1 Assessment Principles

Product assessment shall follow the following principles:

---Ideological principle of life cycle: use the thought of life cycle to systematically consider important environmental factors that have a relatively significant influence on the environment at the various stages of the product's full life cycle;

---Principle of combination of qualitative and quantitative assessment: the implementation of eco-design product assessment shall propose qualitative or quantitative assessment indexes. If feasible, the selection of quantitative assessment requirements is encouraged, so as to reflect the environmental performance of the product more accurately.

4.2 Assessment Methods

The product assessment methods are as follows:

---Index assessment, including but not limited to:

- Environmental protection requirements stipulated in laws and regulations;

- Other advanced environmental protection requirements for the product, including industry environmental protection policies, national (industry) technical standards, customers' requirements, environmental protection marks or green procurement technical specifications, etc.

---Life cycle assessment: in accordance with GB/T 24040-2008, GB/T 24044 and GB/T 40093-2021, implement the product's life cycle assessment.

4.3 Assessment Bases

The product shall be assessed as eco-design product in accordance with the following conditions:

---Satisfy the manufacturer's basic requirements (see Chapter 5);

---Satisfy the product's assessment index requirements (see Chapter 6); provide relevant conformity certification documents;

---In accordance with GB/T 24040-2008, GB/T 24044 and GB/T 40093-2021, implement the product's life cycle assessment; provide eco-design assessment report.

5.1 Requirements for Management Systems

The manufacturer shall comply with the requirements of GB/T 19001, GB/T 24001, GB/T 45001 or equivalent standards to establish and effectively operate the quality management system, environmental management system and occupational health system.

5.2 Other Basic Requirements

The other basic requirements shall include:

---The discharge of pollutants shall comply with national or local pollutant discharge standards, and the total pollutant control shall reach the total pollutant discharge control index;

---Advanced technologies and processes encouraged by the state should be adopted; eliminated or prohibited technologies, processes, equipment and related substances issued by the state or relevant departments shall not be used;

---There shall be special storage places for solid wastes, so as to avoid scattering, loss and leakage; the generation and hazards of solid wastes shall be reduced; solid wastes shall be thoroughly and reasonably exploited and be subjected to harmless disposal;

---In accordance with the relevant requirements of GB/T 24256 and GB/T 28180, implement the product's eco-design. The product quality, safety, energy conservation and consumption reduction, and comprehensive utilization level shall reach the relevant requirements of national and industry standards.
