Overview
The Global Network for Zero (GNFZ) offers certification for existing buildings to help them achieve net-zero carbon emissions. The program evaluates a building’s energy use and carbon footprint, then provides a roadmap to reduce emissions. This certification can help building owners improve efficiency and sustainability.
Since its inception, GNFZ has certified numerous buildings, achieving significant carbon reductions. Key partners include prominent real estate firms and environmental organizations. Buildings that earn the certification often see lower energy costs and higher property values. The For Buildings Certificate ensures that a structure meets rigorous standards for energy efficiency and sustainability.
By offering a clear, actionable path to net-zero, GNFZ enables building owners to contribute to global carbon reduction goals.
Requirements & Verification
Evidence Requirements
Applicants must submit documentation of their building's Scope 1, 2, and 3 emissions through a formal assessment process. A net zero plan must be drafted with GNFZ support outlining the transition strategy. Annual documentation must be submitted to maintain net zero certification status. Milestone certificates are issued at each stage: emissions assessment, net zero plan, and full net zero certification.
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) a net zero plan developed with GNFZ support outlining the transition strategy; and (3) full net zero certification upon achieving net zero status, with annual documentation submissions required for ongoing verification. Milestone certificates are issued at each stage.
Renewal & Compliance
Certified buildings must submit annual documentation to maintain their net zero certification status. This ongoing reporting ensures continued compliance with the net zero standards and allows GNFZ to verify that the building's emissions performance is being maintained or improved over time.

Consider Alternatives If...
Avoid this certification if your building is newly constructed and better suited to a new-construction net-zero standard, or if you need a widely recognized credential like LEED or ENERGY STAR that carries broader market recognition among tenants and lenders.
