This research investigates how awareness of pro-social job meaning influences worker performance in environmentally impactful sectors. Through a field experiment at a Chinese environmental protection equipment manufacturer, we examine how connecting workers to their products’ environmental contribution affects work outcomes. We design a randomized controlled trial withapproximately1,200 workers and implement information interventions to educate workers about the environmental impact of their products. By analyzing productivity, job satisfaction, and turnover rates across treatment groups, we assess whether strengthening workers’ connection to their environmental mission enhances individual and team performance
