GNFZ Net Zero Milestone Certificates
Global Network for Zero
Earn certification for achieving net zero in existing buildings.
Key Strengths
- Incremental milestone-based pathway makes net zero accessible to all building types
- Covers Scope 1, 2, and 3 emissions — comprehensive GHG accounting
- Based on the industry-leading GHG Protocol standard
- Recognized by GRESB in its ESG reporting process
- Aligned with SBTi targets and international ESG/green building regulations
- End-to-end support provided throughout the certification journey
Ideal For
This certification is best suited for owners and managers of existing commercial, residential, or institutional buildings seeking a structured, incremental pathway to net zero emissions. It is particularly valuable for real estate companies, property developers, and facility managers who need to align with ESG reporting frameworks like GRESB or meet SBTi targets. Organizations looking for an accessible, step-by-step approach rather than an all-or-nothing certification will find this program especially well-matched.

Building Scope
Overview
The Global Network for Zero (GNFZ) offers the Net Zero Milestone Certificates program aimed at certifying existing buildings that achieve net-zero energy consumption. The program began to address rising environmental concerns and promote sustainable practices. Certification involves a thorough assessment of a building's energy use, systems, and improvements. According to GNFZ, several buildings have achieved certification, showcasing significantly reduced energy usage and enhanced efficiency. Noteworthy clients include commercial buildings, educational institutions, and municipal facilities. The program collaborates with energy consultants and sustainability experts to guide the certification process, ensuring reliability and accuracy in achieving net-zero energy goals.
Requirements & Verification
Evidence Requirements
Applicants must submit documentation covering Scope 1, 2, and 3 emissions calculations for their building. This includes an initial emissions assessment, a drafted net zero transition plan, and — upon achieving certification — annual documentation demonstrating maintained net zero status. Additional milestone certificates may be requested to document incremental progress throughout the project.
Prerequisites
Assessment Process
The certification process involves three stages: (1) an emissions assessment in which the building's Scope 1, 2, and 3 emissions are calculated and documented; (2) development of a net zero transition plan with GNFZ support; and (3) final net zero certification upon demonstrating emissions elimination. Annual documentation submissions are required to maintain certification. GNFZ provides end-to-end support throughout the process. Additional milestone certificates can be issued to recognize incremental progress.
Renewal & Compliance
Certified buildings must submit annual documentation to maintain their net zero certification status. This ongoing reporting ensures continued compliance with net zero emissions standards. Additional milestone certificates can be requested to document progress at any point during the journey.

Consider Alternatives If...
Organizations seeking a single, widely-recognized green building label (such as LEED or BREEAM) that covers broader sustainability criteria beyond emissions may find this program too narrowly focused on net zero carbon. Buildings that are not yet ready to commit to annual documentation and ongoing emissions reporting may find the renewal accountability requirements burdensome.
