FIRST IN THE NATION!

Congratulations, Yerba Buena Warriors! You have kicked gas off your grass and the results are measurable and impressive (see DATA section below). Beyond metrics, your most impressive achievement is actually your truly outstanding sustainability vision and leadership that made all of this possible. We are honored to have been included in your portfolio of innovative projects and are grateful for your enthusiasm and collaboration.

Let’s Celebrate!

AGZA looks forward to formally certifying and celebrating with Yerba Buena on Monday, May 13th!

Overview

Yerba Buena High School has established the first AGZA Green Zone®High School in the nation! This groundbreaking advancement adds to the ongoing sustainability leadership at YBHS. By transitioning from noisy, highly polluting gas machinery to low-noise zero-emission tools and operations, the high school will eliminate smog-forming emissions and greenhouse gasses from routine grounds maintenance while also dramatically reducing noise levels, solid and toxic waste streams, and ongoing operational cost.

AGZA’s goal is to help YBHS and the entire East Side Union High School District (ESUHSD) maximize its investment in sustainable equipment, operations and crew. AGZA Green Zone Certification ensures your electric operations are safe, stable, effective, and profitable. The AGZA Green Zone at YBHS will be a model for low-impact land maintenance that can be scaled to the other ten high schools in ESUHSD and inspire other schools across the country.

esuhsd is proud to collaborate with agza as it highlights our continued commitment in providing a healthy and safe environment to students, staff, and community members

DATA

Every year the AGZA Green Zone prevents over four tons (4.38t) of airborne pollution from land care operations at YBHS, while reducing noise levels 40% - 70%. Fuel spillage, evaporative emissions and solid waste from gas maintenance have been completely eliminated. Significant reductions in hourly operational costs from the gas fleet — fuel, oil, parts, and maintenance — will achieve a healthy ROI on the new electric fleet, and ongoing savings thereafter.

 • TOTAL AIRBORNE POLLUTANTS eliminated
• CARBON DIOXIDE (CO2) eliminated
• CARBON MONOXIDE (CO) eliminated
• HYDROCARBONS (HC) eliminated
• PARTICULATE MATTER (PM 2.5) eliminated
• NITROGEN OXIDES (NOx) eliminated
• NOISE REDUCTION
• FUEL, OIL and GAS-RELATED PARTS
• MAINTENANCE TIME and COSTS
• OPERATIONAL COSTS
• COMMUNITY SUSTAINABILITY AWARENESS
