The Building Emissions Reduction Standard
The Building Emissions Reduction Standard (BERS) serves as the foundation for certifying emissions reductions for building retrofit projects under Ontoly’s program. It outlines the key principles and requirements that guide the certification process, ensuring credibility and market integrity.
Program Documents
The Ontoly Building Emissions Reduction Standard is supported by a set of core program documents that define how projects are evaluated, quantified, and certified. These documents establish the rules, procedures, and quality standards required for participation—ensuring consistency, transparency, and credibility across all projects.
Together, they serve as the foundation for how emissions reductions are calculated, verified, and tracked. Below, you'll find the key documents that guide participation in the program:

Methodologies
Methodologies are distinct from the core program documents, but they play a critical role in how emissions reductions are calculated. Each methodology outlines the specific formulas, project boundaries, data requirements, and parameters used to quantify reductions.
Only approved methodologies can be used under the Ontoly Building Emissions Reduction Standard.
