AGZA Certified Green Zone

An AGZA Green Zone is one in which routine maintenance is independently verified for low impact operations. AGZA Green Zone Certification is a structured program involving education, training, certification, and data® reporting to achieve an enduring transition to cleaner, quieter, more sustainable landscape maintenance practices.
AGZA and nonprofit Quiet Communities work together to implement the program nationwide in parks, municipalities, institutions, and businesses.
