Real Impact, Real Stories
See how leading organizations are leveraging SINAI’s Decarbonization and ESG Platform to achieve their sustainability goals.
Optimus Steel partnered with SINAI to replace spreadsheet-based carbon accounting with a centralized, auditable GHG management platform. With SINAI, this transition enabled the digitization of scopes 1, 2, and 3 emissions over the last five years, and supported an inventory structure for product carbon footprint (PCF) calculations.
With SINAI, Minerva consolidated their carbon management initiatives, covering Scope 1, 2, and 3 emissions. The platform enabled bulk data uploads, advanced scenario modeling, and financial feasibility analysis. These features allowed Minerva to build a dynamic database of projects and maintain continuity in their decarbonization strategy.
Natura’s collaboration with SINAI has transformed its approach to sustainability, providing a centralized platform to manage emissions data accurately and prioritize high-impact mitigation projects. Natura is now positioned to achieve its Net Zero target by 2030. - Reduced GHG Inventory Preparation Time: By automating processes, Natura decreased inventory preparation time by 80%, freeing up resources to focus on strategic decarbonization efforts. - Enhanced Scope 3 Calculation Accuracy: SINAI’s region-specific methodologies improved the reliability of Natura's scope 3 emissions data, creating a strong foundation for their decarbonization strategy. - Integrated Financial and Environmental Decision-Making: The Marginal Abatement Cost Curve enabled Natura to assess projects' environmental and financial impacts, ensuring the most cost-effective pathway to their sustainability goals.
