Supply Chain Decarbonization and SME Enablement focuses on reducing greenhouse gas emissions across the entire supply chain while empowering small and medium-sized enterprises (SMEs) to participate effectively in this transition. Decarbonizing supply chains involves adopting sustainable practices such as energy efficiency, renewable energy use, low-carbon materials, and optimized logistics. Large corporations often drive these efforts by setting emissions targets and requiring suppliers to comply with environmental standards. However, SMEs face challenges like limited resources, technical expertise, and financial constraints, making it harder for them to implement decarbonization measures independently. Enabling SMEs involves providing access to tailored tools, training, financing options, and collaborative platforms that support their sustainability efforts. Governments, industry groups, and larger companies play critical roles in facilitating SME engagement through policies, incentives, and partnerships. Overall, integrating SMEs into supply chain decarbonization is essential for achieving broader climate goals, as SMEs constitute a significant portion of global supply chains. Supporting their transition not only reduces emissions but also fosters innovation, competitiveness, and resilience in the economy.
