To advance its sustainability targets, Hisensehitachi deployed 27 4IR solutions at its Qingdao site to reduce emissions across the entire product lifecycle – from in-house refrigerant leakage (96% of Scope 1) and R&D operations (46% of Scope 2) to material sourcing and customer site usage (over 90% of Scope 3). Using IoT and advanced analytics, the team reduced refrigerant leakage by 56% and redesigned key processes, cutting Scope 1 and 2 emissions by 48%. Tailored control strategies for environmental parameters at customer sites led to a 28% reduction in Scope 3 emissions from product use.
