Green Jacks


Green Jacks, also known as the Student Environmental Caucus, seek to create a culture of sustainability on campus. Every student, faculty, staff, and administrator at the university can be a Green Jack.

As an organization, the Green Jacks respond to the interests of its members. A few signature events include Better World Film Series, Earth Jam, and helping out with Earth Week. If you have an idea for an event please let us know.

Co-Chair - Mackenzie Gargano

Mackenzie Gargano


I am studying Environmental Sciences with an emphasis in Management and certificate in International Forestry and Conservation. I am in the Honors College and I work as a student ambassador for NAU. I am from Gilbert, Arizona and during my childhood my family spent a lot of time in Northern Arizona. I fell in love with Flagstaff’s outdoor culture and community of sustainability. I enjoy spending my free time exploring the Southwest with friends on weekend adventures. My experiences in nature have formed my passion for the environment. During my time at NAU I have been an active member of several organizations within Green NAU. I was a Sustainability Mentor and had the opportunity to educated freshman about sustainable living. I have also been a member of Green Jacks since freshman year and I'm excited to be in a leadership position. I have a passion for the natural world and hope to share my passion with others.


Co-Chair - Paxson Lowther

Paxson Renee 

I was born and raised in Anchorage, Alaska. This is my third year at NAU and I am double majoring in Environmental Engineering and Spanish. I will be going abroad to South America for a year in Fall 2018 through the Global Science and Engineering Program. Growing up in Alaska I spent the majority of my time outside, and was able to grow up in one of the most beautiful places. My experiences in Alaska have given me a passion for sustainability and allowed me to become very close to the environment. I plan to dedicate my life instilling sustainability in engineering and our community. Since my Freshman year, I have been a Peer Jacks Mentor, been very involved with the American Society of Civil Engineers, and have been involved with various other Green NAU clubs. I have been an active member of Green Jacks since my Freshman year and am extremely excited to take the role of Co-Chair with Mackenzie!
