This report examines the opportunity for accelerating Fort Collins’ energy and climate goals to reflect the community’s values while capturing economic, social, and environmental benefits. In the five years since Fort Collins initially established its current greenhouse gas emissions goals, rapid changes in the cost and availability of clean, energy efficient technologies, together with the emergence of new business models and financing methods for implementing these measures, have dramatically shifted the solutions space for addressing the community’s energy needs. The cost of solar panels, for example, has fallen nearly 75% since 2008, with further dramatic declines yet to come; the retail price for energy- efficient LED lightbulbs has fallen by 50% in the past year. These and other changes have opened the door for the City to implement new solutions to reduce emissions and waste, stimulate local economic development, improve security, and reduce risk. This analysis indicates that, in the accelerated scenario, Fort Collins can achieve an approximate 80% reduction in CO2 emissions by 2030, two decades ahead of its existing 2050 greenhouse gas reduction target. In doing so, the community could: reduce building energy use by 31% through efficiency, achieve a carbon neutral electricity system by 2030, and reduce transportation energy use by 48%.
