Autonomous GHG Protocol Accounting, Scope 3 Supply Chain Intelligence & Regulatory ESG Reporting

An enterprise-grade, open-core software platform designed to automate Scope 1, Scope 2, and Scope 3 greenhouse gas calculations, streamline mandatory SEBI BRSR Core disclosures, and optimize supply chain decarbonization.

Platform Overview » · Documentation » · Schedule Enterprise Demo »

ZeroCarbon is an autonomous corporate carbon accounting and regulatory ESG reporting platform built for enterprise supply chains, sustainability officers, and compliance leads. Designed to eliminate manual data entry and fragmented spreadsheets, ZeroCarbon integrates directly with enterprise ERP systems (SAP, Oracle, NetSuite), smart utility meters, and vendor logistics channels to generate real-time, audit-grade carbon inventories.

Engineered with complete alignment to GHG Protocol, SEBI BRSR Core, GRI, CSRD, and ISO 14064 frameworks, ZeroCarbon enables organizations to measure, track, and report Scope 1, 2, and 3 emissions with continuous mathematical precision.

• Mission: Deliver seamless, audit-ready carbon intelligence software that enables enterprises to quantify, track, and lower their global carbon footprint automatically.
• Vision: Serve as the core software infrastructure powering net-zero transformation and regulatory ESG compliance across global supply chains.

• Scope 1 (Direct Emissions): Fleet tracking, stationary fuel combustion, process emissions, and fugitive refrigerant monitoring.
• Scope 2 (Indirect Energy Emissions): Dual-reporting calculation engine supporting location-based and market-based power grid metrics (including CEA India grid intensity factors).
• Scope 3 (Value Chain Emissions): Full coverage across Purchased Goods & Services, Freight & Logistics, Waste Management, Business Travel, and Employee Commute.

• SEBI BRSR Core: Pre-configured calculation pipelines mapped directly to mandatory Indian market regulatory guidelines.
• Global Standard Cross-Walk: Automatically maps environmental metrics across GRI, TCFD, CDP, and EU CSRD reporting frameworks.
• One-Click Audit Exports: Instantly generate verified PDF calculation sheets, structured Excel ledgers, and digital XBRL reporting outputs.

• Automated Document Parsing: Advanced OCR parses vendor invoices, utility receipts, and freight bills to extract energy and activity data (kWh, liters, metric tons).
• Dynamic Factor Matching: Machine learning engine maps unstructured line items to validated global emission factor databases (DEFRA, IPCC, US EPA, CEA).
• Anomaly & Leakage Detection: Automated monitoring alerts sustainability managers to missing receipts, data input spikes, and potential accounting gaps.
