About ANZ/PH

Advancing Net Zero Philippines (ANZ/PH) is a program of the Philippine Green Building Council (PHILGBC) to transform the design, construction and operations of projects towards the net zero goal.

ANZ/PH aims to transform the built environment by reducing resource consumption and emissions, and shifting towards more sustainable sources to keep projects' impacts at neutral or even provide positive benefits.

ANZ/PH is aligned with the global campaign of the World Green Building Council (WorldGBC) to accelerate the uptake of net zero carbon buildings to 100% by 2050.

As part of program, rating schemes, tools and documents are being developed to support the development and implementation of net zero projects, including the certification of net zero projects.

Certification

What is Advancing Net Zero Philippines Certification?

Advancing Net Zero Philippines Certification is the formal assessment, rating, and certification process for projects of the ANZ/PH Program. It is conducted in a third-party assessment process to ensure a credible, independent, impartial, and objective assessment, rating, and certification of projects under the ANZ/PH.

Only projects that complete the formal process, complies with all requirements, and receives at least the minimum rating for certification may claim as an Advancing Net Zero certified project.

Who will certify your project?

The PHILGBC will certify the project based on the outcomes from the assessments during the Net Zero Certification process.

The PHILGBC or its authorized assessment body will facilitate and conduct the assessment, rating, and certification process. The PHILGBC builds trust and confidence in the system by managing and addressing conflicts of interests between the project, the project team, and the assessment team assigned for the project.

How can you get you project certified?

To get certified as an Advancing Net Zero project under the ANZ/PH Program, you must:

Register your project.
Successfully complete the assessment and certification process using an Advancing Net Zero Rating Scheme.

The project must complete the Advancing Net Zero Philippines Certification process, comply with all minimum system requirements, and achieve the minimum rating for certification.
