For Isaac's 5th grade science project, he researched carbon footprint statistics and climate change education. Since then, his passion for the topic has only grown. He was particularly inspired by meeting Bill McKibben, co-founder of 350.org, after which he began a campaign to get the city of Beaverton to divest from fossil fuels. Isaac dedicated his bar mitzvah (a Jewish rite of passage) project to this effort, and gathered more than 500 signatures for divestment. Isaac is also a member of Plant for the Planet, and helped organize the first ever Plant for the Planet Academy in the U.S. outside of Washington state.

Isaac has been named a Climate Justice Ambassador, and taken part in Youth Climate Leadership Training.
