Formulation and Implementation of Green Procurement Standards
Green procurement standards should cover the full product life cycle: raw material acquisition (recyclable or environmentally friendly materials), manufacturing (ISO 14001 certification), product energy efficiency (Grade 1 energy efficiency or energy-saving certification), use phase (energy consumption and emission levels), and end of life (recyclability rate). Tender documents should specify mandatory green procurement requirements: energy efficiency grade not lower than the energy-saving evaluation value; refrigerant GWP not exceeding 1500 (not exceeding 750 after 2025); compliance with the RoHS Directive. Incentive clauses: bonus points for recyclable material proportion not less than 20%; bonus points for ISO 14001 certification.
Procurement Strategy for High-Efficiency Energy-Saving Equipment
The procurement strategy should start from optimal life-cycle cost rather than simply the lowest price. Measures: set minimum energy efficiency thresholds (chiller COP not less than 6.3, pump efficiency not less than 75%, motors not lower than IE3, transformer no-load loss not higher than SCB13 level); adopt a tiered energy efficiency bonus point system; require submission of LCC analysis reports; encourage the use of variable frequency technology; give priority to equipment utilizing renewable energy.
Procurement Requirements and Certification for Environmentally Friendly Materials
Environmental material procurement requirements: select low-GWP refrigerants (R513A replacing R134a, R290 replacing R22); environmentally friendly closed-cell rubber-plastic insulation free of CFC and HCFC, with thermal conductivity not higher than 0.035 W/mK; stainless steel or copper pipes for water supply to avoid heavy metal contamination; low-smoke halogen-free flame-retardant cables to reduce toxic gases in fires; water-based low-VOC coatings and sealants. Certification requirements: China Environmental Labelling certification (Ten-Ring) or international certifications (Greenguard, Blue Angel); provide environmental performance test reports and MSDS.
Green Supply Chain and Carbon-Neutral Procurement
The green supply chain extends environmental requirements across the supplier's entire chain: ISO 14001 certification; carbon emission data verification; green logistics optimization; environmental compliance with no major penalties. Carbon neutrality management encourages suppliers to achieve carbon neutrality by purchasing carbon sinks or using green electricity. Marriott International has set a target of achieving net-zero carbon emissions by 2040. Green supply chain implementation steps: environmental qualification review (screening before tender); incorporation of environmental scoring into bid evaluation (weight 5%-10%); contract environmental clauses; environmental supervision during contract performance.
