The IGBC Net Zero Carbon rating system is a voluntary and consensus-based programme. The rating system is fundamentally designed to encourage the use of low-embodied carbon materials, optimise the buildings’ performance using passive features and technologies, and use of on-site & off-site renewable energy systems and carbon sequestration measures to reduce or off-set the carbon emissions associated with the buildings and its concerned environment.
The rating system evaluates certain mandatory requirements & credit points using a prescriptive approach and others on a performance-based approach.
The IGBC Net Zero Carbon rating system addresses the three pillars of sustainability i.e., Social, Environmental and Economical; thereby, the building and campus projects adopting net zero carbon concepts can have multi-fold tangible and intangible benefits.
The IGBC Net Zero Carbon rating system promotes resource efficiency and encourages use of renewable energy and carbon sequestration measures to offset carbon in Design & Construction phase and Operations phase through the following:

The different levels of rating awarded are as below:
Design & Construction phase
| Certification Level |
|---|
| Near Net Zero Carbon |
| Net Zero Carbon |
Operation phase
| Certification Level |
|---|
| Near Net Zero Carbon |
| Net Zero Carbon |
IGBC will recognise Net Zero Carbon Buildings that achieve one of the rating levels with a formal letter of certification for Design & Construction Phase Certified projects and with a formal letter of certification & a mountable plaque for Operation Phase Certified Projects.
The rating awarded for IGBC Net Zero Carbon under Design & Construction phase or Operations phase would be valid for a period of 3 years. The projects certified under Design & Construction phase shall apply for Operations phase certification with the prevailing version. The projects certified under Operations phase shall apply for recertification with the prevailing version.
