In college, I've mostly done this through the Climate Reality Project: Campus Corps (CRCC) chapter at NC State University. The Climate Reality Project is a non-partisan non-profit devoted to "empowering everyday people to become activists, equipped with the tools, training, and network to fight for solutions and drive change planet-wide." They accomplish this through providing leadership trainings and supporting local chapters.

My student chapter (CRCC at NC State) focuses on campaigning for achievable, scientifically informed solutions and policies our university can adopt in order to reduce its greenhouse gas emissions. In the past, we've campaigned for our university to generate electricity through renewables and for adopting builiding codes that emphasize energy efficiency. Most recently, our efforts have been focused on a divestment campaign. NC State has at least $43 million of its $1 billion endowment invested in fossil fuel commodities, and an unknown (likely far larger) amount invested in fossil fuel-associated companies. We believe the university can and should smartly reinvest these assets in an environmentally- and socially-responsible manner.
