About CorpStage

We Build ESG Systems That Stand Up to Scrutiny

ESG is now tied to enterprise value, capital access, and regulatory risk. But most organisations still treat it as a reporting exercise.That is where it fails.

Data cannot be traced. Assumptions are unclear. Finance cannot validate the numbers. Disclosures do not hold under investor or audit scrutiny.

ESG is reported. But ESG is not trusted.

CorpStage exists to close that gap by combining deep ESG expertise, financial discipline, and CorpStage 360 to build structured, governed, and audit-ready ESG operating models.

ESG is not reporting.
It is financial and operating infrastructure.

The new standard is evidence-based sustainability—where every claim is defensible, every metric traceable, and every decision backed by governance, risk, and financial impact analysis.

How we build ESG operating models

One ESG Operating Model. Four Integrated Layers.

Most organisations approach ESG as a reporting or compliance exercise. CorpStage approaches it as a system design and implementation challenge.

01

ESG Data Architecture

We design structured ESG data environments across entities, facilities, operations, and value chains

  • Source-to-disclosure data lineage
  • Integration with ERP, finance, and operational systems
  • Standardised data models across business units
02

Methodology & Measurement Systems

We define how ESG metrics are calculated, estimated, governed, and documented so every number can be explained and defended.

  • Metric definitions aligned to ISSB, CSRD, GRI, and TCFD
  • Estimation hierarchies and boundary consistency
  • Documented calculation logic and assumptions
03

Governance, Controls & Assurance Readiness

We embed ESG into organisational control frameworks so data collection, review, approval, and evidence are managed with discipline.

  • Approval workflows and accountability structures
  • Evidence management and audit trails
  • Alignment with COSO and emerging assurance expectations
04

Decision & Output Layer

We translate ESG data into outputs that matter for boards, investors, lenders, buyers, auditors, and regulators.

  • Investor-grade ISSB and CSRD disclosures
  • Lender-ready ESG data for financing
  • Buyer and supply chain compliance documentation
Implemented through CorpStage 360

Founder & CEO

Dr. Nisha Kohli

Dr. Nisha Kohli brings over two decades of experience across finance, governance, and corporate strategy. A Chartered Accountant, PhD in Corporate Governance, and CFA Level III candidate, her work sits at the intersection of financial discipline and ESG transformation.

Her perspective was shaped through research into corporate failures where organisations appeared compliant, yet lacked the structural resilience to withstand real-world stress.

A checklist is not a strategy.

This insight became the foundation of CorpStage—moving ESG from paper-based promises to systemised, defensible, and financially integrated operating models.
