75 Baozun Inc. 2022 Annual Sustainability Report Green Warehousing and Logistics As a bridge between e-commerce and consumer terminals, warehousing and logistics is one of the core competencies that Baozun has invested in for a long time, and it is also a key link for Baozun to practice green and low-carbon operations. We have created low-carbon automated warehouse and logistics systems, optimized warehousing and sorting equipment and lighting systems, and continuously optimized energy consumption for vehicles. Besides, we put 365 integrated energy service platform on line in warehousing and logistics parks, which provides visualization and real-time monitoring of water, electricity, gas, etc., thus promoting the sophisticated management of energy and resource consumption. In terms of green transportation vehicles, Baozun continuously optimizes transportation carriers, transportation vehicle energy use and transportation routes. For short barges within the city, the Company gives priority to suppliers with new energy vehicles as replacements for the former fuel-powered vehicles. As for the vehicles used within the park, electric forklifts are used as tractor vehicles, and by optimizing the size and capacity of the forklifts and the transport routes in the park, the number of empty vehicles and the number of electric forklift transports with the same operational volume are reduced. Thus, the annual electricity savings can reach 14,600 kW·h. In addition, Baozun optimizes energy-saving forms of logistics while continuously promoting the development of freight transportation to public-to-rail and public-to-water modes, and enhancing the proportion of rail and waterway freight transportation. For medium and long distance transportation, we gradually employ more railroad and waterway transportation to reduce carbon emissions resulting from air transportation. ◎ Major Energy Saving and Consumption Reduction Measures of Baozun Green Storage in 2022 • Introduced sophisticated automation equipment and intelligent robots to achieve intelligent transfer and sorting, and monitored equipment operation and energy consumption in real-time. • Reduced the idle time of assembly line under the premise of meeting the demand of goods transmission, from 40 seconds to 20 seconds, and increased the independent control button of empty crate recycling to reduce the idling rate of assembly line. • Re p l a c e d e q u i p m e nt wi th e n e rgy-s avi n g equipment, utilized LED energy-saving lighting in the park, and replaced ordinary lights with photovoltaic lights in the warehouse and docks. • Partitioned lighting control was used for operating and non-operating areas. • Divided hot/cold goods according to product sales and the size of replenishment demand, carried out centralized management of goods, and ensured 24/7 activation of electrical equipment in the zero picking area (the main operation area where hot goods are located) and activation of lighting in the replenishment area during regular hours, thus reducing the lighting hours in the replenishment area by 50% and lowering energy consumption. • The park's outdoor search lights were fitted with timer switches; the permanent lighting in the corridors of the storage area, picking area, restrooms and other places were replaced with sound and light control sensor lights.

Protecting Our Beautiful Earth with Green Development 80 Emissions Management Baozun's business does not involve production and manufacturing, and the Company has no production-related air pollutants and wastewater emissions. Solid waste is mainly generated from warehousing and logistics, including living and electronic waste from the canteen and office areas. The Company classifies and either disposes of solid waste or utilizes it effectively. In 2022, Baozun's Wujiang Yongding Park calculated the amount of monthly storage waste generated according to recyclable (cartons, waste printing paper, etc.), dry waste (other waste in the warehouse except recyclable) and wet waste (food waste) to have an accurate idea of the amount of waste generated and the type of waste in the park. The statistical results show that 86.54% of the waste in Yongding Park in 2022 is in the recyclable category and can be effectively treated and reused. On this basis, the park keeps track of the most terminal disposal institutions and uses of waste such as recycled cartons, recycled pallets and meal waste. Among them, the park's waste cartons and waste paper are used as raw materials for recycled paper; pallets are processed and reused through third-party factories; and food waste is decomposed and utilized. The remaining portion of dry waste is completed incinerated at the waste-to-energy plant. Therefore, the proportion of waste that actually gets effectively treated in Yongding Park will be further increased. Baozun actively advocates the concept of sustainable development. It supported a certain brand's "New Green Life in the Desert" sustainable fashion project on e-commerce platforms, taking the lead in green fashion together with the brand and influencing consumers on e-commerce platforms. When consumers purchase low-carbon products from our brand partners, opt for green packaging and use greener logistics options on the e-commerce platform, they will have the opportunity to win a limited number of green digital collectibles from the e-commerce platform and be rewarded with "little green flowers” that can be redeemed for more beautiful gifts from our brand partners.

Sustainable Development Performance 82 Notes: [1] The scope of Environment KPIs includes: Baozun Inc., its consolidated subsidiaries, its variable interest entity and its subsidiaries, which are consistent with the entities covered in the consolidated financial statements included in Baozun's annual report for the year ended December 31, 2022. Compared to 2021, the company's consolidated financial statements in 2022 no longer include Suzhou Baoleantone International Logistics Co., Ltd. [2] Compared to 2021, the decrease in electricity consumption, diesel, integrated energy consumption and energy consumption per revenue in 2022 is mainly due to the energy-saving measures taken and the reduction in energy consumption in the head office as well as logistics and warehousing due to the impact of the epidemic prevention and control. [3] In 2022, new photovoltaic power generation equipment was added to the headquarters office building and part of the campus. [4] The significant increase in natural gas consumption in 2022 compared to 2021 is mainly due to the provision of staff canteens following the relocation of the head office in October 2021, with the natural gas consumption statistics for 2021 covering October-December and the natural gas statistics for 2022 covering 1 January to 31 December 2022. [5] Greenhouse gas emissions in Scope 1 include natural gas, gasoline and diesel for vehicles owned by the Company. When calculating natural gas, gasoline and diesel carbon emissions, we refer to the Accounting and Reporting Guidelines for Corporate Greenhouse Gas Emissions - Power Generation Facilities (revised version 2022) issued by the Ministry of Ecology and Environment of the People's Republic of China. [6] The source of greenhouse gas emissions in Scope 2 is purchased electricity. For the accounting methods for greenhouse gas emissions refer to the Accounting and Reporting Guidelines for Corporate Greenhouse Gas Emissions - Power Generation Facilities (revised version 2022) issued by the Ministry of Ecology and Environment of the People's Republic of China. In particular, the carbon emissions from purchased electricity are calculated by power grid emission factors, which was issued by the Ministry of Ecology and Environment of the People's Republic of China. The power grid emission factor in 2020 is 0.6101 kg CO2e/kW·h, in 2021 is 0.5810 kg CO2e/kW·h, respectively and in 2022 is 0.5703 kg CO2e/kW·h. [7] The increase in water consumption per revenue in 2022 compared to 2021 is mainly due to lower total operating revenue in 2022 compared to 2021. [8] Compared to 2021, the amount of non-hazardous waste generated in 2022 has been significantly reduced, mainly due to the impact of epidemic prevention and control.
