Emitwise vs Siemens Energy
Side-by-side comparison of AI visibility scores, market position, and capabilities
Emitwise provides enterprise greenhouse gas management software with automated Scope 3 supply chain emissions calculation powered by machine learning.
About
Emitwise is a climate technology company founded in 2019 in London that has raised $15M to build enterprise GHG management software with a particular focus on automating the most difficult part of carbon accounting: Scope 3 supply chain emissions. The platform uses machine learning to classify procurement spend data into emissions categories, apply appropriate emissions factors, and calculate upstream and downstream emissions at scale without requiring suppliers to provide primary emissions data. This automated spend-based approach enables companies to quickly establish Scope 3 baselines that would otherwise require months of manual data collection. Emitwise integrates with ERP systems including SAP and Oracle to pull spend data automatically and provides supplier engagement tools for collecting primary emissions data from key suppliers over time. The company serves medium and large enterprises in manufacturing, retail, and professional services that have committed to science-based targets and need to address their supply chain emissions. Emitwise has found strong market fit in Europe where regulatory pressure from CSRD and customer expectations are driving corporate investment in Scope 3 measurement capabilities.
