CASE STUDY 4 Siemens: scaling low-carbon solutions via Xcelerator platform As a leading technology company, Siemens commits to achieving net-zero greenhouse gas emissions across entire value chain by 2050 and is uniquely positioned to spearhead this transformation for entire industries, with more than 90% business enabling customers to achieve a positive sustainability impact. In 2021, Siemens launched Zero-carbon Pioneer Initiative in China, to co-create a green ecosystem with all partners; in 2022, Siemens Xcelerator was launched to accelerate digital transformation, as an open digital business platform for driving sustainability. Core initiative –Siemens Xcelerator “Green and Low-Carbon Theme Category”: one-stop platform offering comprehensive information, professional insights, success stories,and cutting-edge solutions co-created with partners. –Supply chain management (SCM) X: A pioneering digital hub on Siemens Xcelerator, designed to empower suppliers’ sustainability progress, featuring four modules: SCM Academy for knowledge building, Siemens Solutions, Supplier Collaboration and Supplier Innovation. As an all-in-one platform, it enables suppliers to explore, learn and advance sustainability. –Package resuable collaboration with Horen: As an intelligent reusable transit packaging provider, Horen reduces upstream emissions of Siemens’ Tianjin factory, saving 54 tons of solid waste and 80 tons of CO2 equivalent (CO2e) yearly, and scaling across China factories. As Siemens’ partner, Horen co-developed Siemens-powered heavy-duty parts solutions for logistics, launched on Siemens Xcelerator to scale. –Battery recycling with NorthStar: Co-created integrated solutions via Siemens automation, energy management, carbon footprint solution, etc., and developed flexible dismantling for power batteries and printed circuit boards (PCBs) via AI, edge computing, digital twin – all scaled via Siemens Xcelerator. Impact Siemens achieved sustainability outcomes for both its own operations and the value chains. From 2019 to 2025, Siemens Chengdu Factory has boosted its revenue by 73%, while increasing its energy efficiency by 20% via applications of digital twin, AI, energy management systems, etc. By 2025, Siemens has assisted more than 500 key suppliers in China to accelerate their carbon reduction journey, play important role in supporting Siemens globally to reduce CO2 emissions in own operation by 60%, and help more than 10,000 customers in different industries to be more sustainable and resilient.Chain leaders who co-invest in supplier capabilities can transform transactional relationships into strategic partnerships. Shared data platforms, cost- sharing mechanisms and equipping a partnership mindset to enable gap bridging can distribute transition costs while mitigating systemic risks, which is critical in Asia’s fragmented manufacturing ecosystems. This collaborative ethos counters exploitative buyer-supplier dynamics, converting decarbonization into mutual value creation.3.2 Empowering supply chains Standardization is a powerful enabler for scaling industrial decarbonization. By creating unified protocols, shared infrastructure and digital platforms, industrial ecosystems can reduce duplication, lower transaction costs and accelerate adoption of low-carbon solutions. In Asia, strong links between state and industry provide fertile ground for promoting standardized models that can be replicated across regions and sectors. This not only strengthens value chain coordination but also ensures credibility in carbon accounting and reporting. When embedded in industrial clusters, such frameworks allow companies to pool resources, exchange data and integrate circular practices, transforming isolated initiatives into system-wide decarbonization pathways.3.3 Leveraging industrial ecosystems Accelerating Value Chain Decarbonization for Corporate Growth: Perspectives from Asia 20
