Certification is available for any physical facility and their operations, including buildings owned by: businesses, property managers, schools, government agencies and nonprofits. For event eligibility, see the Guide to Event Certification below.

How TRUE works

A TRUE project's goal is to divert all solid waste from the landfill, incineration (waste-to-energy) and the environment. Facilities achieve certification by meeting seven minimum program requirements and attaining at least 31 points on the TRUE Application form available on the Resources page.

Certification requirements

Guide to Certification

The TRUE certification program is an Assessor-based program that rates how well facilities perform in minimizing their non-hazardous, solid wastes and maximizing their efficiency in the use of resources. View the Guide to Certification and TRUE Rating System on the Resources page to learn more.

Guide to Events Certification

In addition to facilities, events are also eligible to receive certification. Eligible events include public or private organized gatherings of people at a predetermined time and place (such as conferences, festivals, entertainment or sporting events, etc.) TRUE for Events certification has been adapted from the original certification program to help events reach their zero waste goals. View the Technical Guide for Events on the Resources page to learn more.


TRUE precertification is an optional, incremental pathway to TRUE certification that prioritizes the core actions essential to getting a successful start toward zero waste. Learn more about the precertification process by reviewing the TRUE Precertification Guidance which outlines details about the process.


TRUE certified projects may recertify by providing annual performance data demonstrating that the project continues to meet zero waste requirements. Projects may also recertify and pursue additional points to upgrade their previous certification level gaining increased recognition. Review the TRUE Certification Maintenance and Recertification Guidance for more details on the recertification and certification requirements.
