Overview
One Click LCA supports projects pursuing certification under the IGBC Net Zero Carbon Rating System (Pilot Version). This framework, developed by the Indian Green Building Council, is designed to guide projects towards achieving net zero carbon through embodied and operational carbon reductions.
Our tools enable project teams to calculate embodied carbon, assign EPDs, and document material-related emissions, ensuring compliance with the IGBC rating methodology.
Life-Cycle & Results Scope
Coverage of embodied carbon across A1–A5 (product and construction stages), B4 (replacements), and C1–C4 (end-of-life) stages.
Optional inclusion of D-stage benefits (reuse, recycling, energy recovery).
Ability to account for operational energy and water consumption to support whole-life carbon balance.
Results expressed as kg CO₂e/m² and total project emissions.
Certification & Compliance Scope
One Click LCA supports the following IGBC Net Zero Carbon credit areas:
Embodied Carbon of Materials
Life-cycle carbon footprint of building materials
Substitution with low-carbon alternatives
Documenting use of products with EPDs
Operational Carbon
Recording and tracking operational energy consumption
Integration of renewable energy contributions
Calculating carbon balance towards net zero
Construction & Demolition Waste
Accounting for waste and recycling impacts through LCA reporting
Environmental Indicators to Report
IGBC’s Net Zero Carbon rating primarily requires reporting of:
Global Warming Potential (GWP) – expressed in kg CO₂e
GWP is the main environmental indicator under this rating, consistent with its focus on achieving net zero carbon.
Data Scope in the Tool
One Click LCA integrates:
Indian-specific datasets where available
EPDs (EN 15804/ISO-compliant) for construction products
