The theme of this year’s Behavior, Energy & Climate Change conference (BECC) is “Scaling Up.” The need to mitigate climate change is more urgent than ever. BECC has been at the forefront of supporting behavioral research to address climate and energy issues for more than a decade. Now is the time to take these established principles and practices and scale them up. Scaling up means looking at the big picture, adapting small interventions for broad application, working with others, addressing policy, and generally taking climate action to the next level. This year, through regular and special sessions, BECC plans to showcase research, programs, organizations, and people that help move toward a sustainable energy and climate future.
