Joho 4 Change🌍🌎🌏

Joho 4 Change has an extensive list of projects and activities students have spearheaded and developed over the school year. We have expanded classroom recycling and started a paper recycling campus program. Some of our club members researched and compiled a resource list of eco-friendly school supplies. Since February 2024, we partnered with Operation 9-2-99 for a monthly Tuolumne River Cleanup. We are hoping to begin a composting project soon. Check out our Monthly Newsletters below!

Teacher Coordinator

In March 2023, the Board approved "Sustainability Teacher Champions" funding at all 34 school sites to establish and lead environmental initiatives. At Johansen High School, History and Social Sciences teacher Seth Simas took on the challenge in addition to his other campus responsibilities. Sustainability Leads will form environmental clubs and guide students through projects focusing on: energy conservation, waste reduction, and air monitoring.

Contact: Seth Simas

💡Energy Conservation

A full-time Energy Education Specialist contracted through Cenergistic monitors Johansen's utility bills and conducts in-person audits to verify HVAC run times and proper lighting usage. The specialist also helps optimize systems to ensure they run efficiently.

Cenergistic provides ongoing training and support, including student engagement opportunities such as "Energy Audits" and "Utility Bill Review." Visit the District Energy Conservation page to learn more!

If you would like more information about this program, contact the Director of Sustainability, Gilbert Blue Feather Rosas, at Rosas.G@mcs4kids.com.

Air Quality and Health

Purple Air Monitor Program

MCS partnered with UC Merced professor Dr. Asa Bradman to install Purple Air Monitors at all 34 school sites. The installation is underway, but stay tuned to see Johansen's real-time outdoor air quality. We hope to initiate after-school programs involving environmental clubs and classes in monitoring and tracking.

Through consistent tracking, the air monitors will develop a baseline for emissions. Students can use software like Excel to find correlations in air quality due to site location and surroundings, weather, time of year, and even time of day.

No Idling Campaign

Idling vehicles create unnecessary, harmful pollution that affect students’ health. The message is simple: While you wait for your child, please turn off your engine. Idling for more than 10 seconds uses more fuel than turning off the engine and restarting it.

San Joaquin Valley Air Pollution Control District: Real-Time Air Advisory Network

RAAN uses actual, real-time air-quality data taken directly from the nearest air monitor to help you evaluate air quality and determine the right time for outdoor activities. It also provides Real-Time Outdoor Activity Risk (ROAR) guidelines based on five different air-quality levels.

🌞Solar on Campus


It's hard not to notice the giant solar panels that now provide shade covering and solar production in the parking lot! Johansen's panels will produce 1308.0 kWh and provide 67,186 sq. feet of shaded covering.

Did you know solar panels absorb significantly less energy (1.8 kWh per square meter per day) than asphalt (5.4 kWh per square meter per day)? This change in energy absorption alters the amount of infrared radiation reaching the ground, providing cooler space for students and transportation staff.

CTE Programs

Climate Action Pathways (CAPS)

Climate Action Pathways for Schools (CAPS) is a California-based non-profit organization providing paid internship programs designed to meet a school district’s climate action goals. Junior and Senior interns' work is focused on reducing greenhouse gas emissions at a school district level developed in 5 key areas, including clean transportation, building decarbonization, food systems, water conservation, and water management.

A cohort of students from MCS high schools, including Johansen, have the unique opportunity to be part of a process of creating change that can be measured and seen within their school and community.

Student Energy Audits!

After analyzing energy data and understanding site plans, our Climate Action Pathways high school interns conducted energy audits of some district campuses. They prepared questions and interviewed head custodians, our Cenergistic Energy Specialist, and other applicable staff.

Future Renewable Energy Pathways

The district's investment in solar carports and an electric school bus fleet, as well as other sustainability initiatives, has sparked interest in developing technical education programs for high school students to pursue renewable energy curriculum in Career Technical Education (CTE) classes.
