2021年9月27日，本批评选出的3家分别来自巴西Flex、中国海尔和德国西门子，主要涉及电子、家用电器、工业自动化等领域。
1. 爱立信（刘易斯维尔，美国）
爱立信5G绿地工厂百分百采用现场太阳能装置提供的可再生电力和公用电网提供的绿色认证®可再生电力。这家智能工厂综合采用了储热/冰罐等可持续技术和工业物联网技术栈，积极监测能耗情况，旨在将能耗降低24%，将室内用水量减少75%，并在同类建筑物的基础上，将运营过程的碳排放量减少97%。今年，这家工厂成为爱立信在全球范围内首个获得LEED金级®认证的工厂。
2. 汉高（杜塞尔多夫，美国）
为了进一步提高工厂能耗的透明度并改善相关决策，汉高在机器上安装了公用事业电表，并将机器纳入数学孪生技术方案，实现了30个工厂的互联和比对，便于实时采取可持续行动，从而将每千瓦时的能耗吨数降低了38%，每立方米的用水吨数降低了28%，每千克产品浪费的能源吨数在2010年的基础上降低了20%。
3. 施耐德电气（莱克星顿，德国）
为了更清晰地了解工厂能耗的分布、时间和环节，莱克星顿智慧工厂采用了物联网技术，同时使用了电表和预测分析技术，旨在优化能源成本，因此将能耗（吉瓦时）降低了26%，将二氧化碳净排放量降低了30%，将用水量降低了20%，并获得了美国能源部卓越能效计划50001认证。

What will be sustainable lighthouses in 2021?
On September 27, 2021, the three companies selected by this criticism were from Flex in Brazil, Haier in China and Siemens in Germany, mainly involving electronics, household appliances, industrial automation and other fields.
1. Ericsson (Lewisville, USA)
Ericsson’s 5G Greenfield plant is 100 percent powered by renewable electricity from on-site solar installations and Certified Green ® renewable electricity from the utility grid. Using a combination of sustainable technologies such as heat storage/ice tanks and the Industrial iot technology stack, the smart factory actively monitors energy consumption, aiming to reduce energy consumption by 24%, reduce indoor water consumption by 75%, and reduce carbon emissions from operations by 97% on a similar building basis. This year, the plant became Ericsson’s first worldwide LEED Gold ® certified facility.
2. Henkel (Dusseldorf, USA)
To further increase the transparency of plant energy consumption and improve decision-making, Henkel installed utility meters on the machines and incorporated the machines into the mathematical twin technology solution, enabling the interconnection and comparison of 30 plants to facilitate real-time sustainable action, resulting in a 38% reduction in energy consumption per kilowatt-hour and a 28% reduction in water consumption per cubic meter. The tons of energy wasted per kilogram of product was 20 percent lower than in 2010.
3. Schneider Electric (Lexington, Germany)
To gain a clearer understanding of the distribution, timing and link of the plant’s energy consumption, Lexington Smart Factory uses iot technology, along with electricity meters and predictive analytics to optimize energy costs, resulting in a 26% reduction in energy consumption (gigawatt hours), a 30% reduction in net CO2 emissions, and a 20% reduction in water consumption. It is also certified by the U.S. Department of Energy’s Energy Efficiency Excellence Program 50001.
