Bus Strat Env. 2019;28:1179–1198. Abstract This study examines whether firms can influence their cost of equity (COE) by broadly disseminating their carbon information over Twitter. We study firms' dissemination decisions of carbon information bydeveloping a comprehensivemeasure of carbon information that a firmmakes onTwitter, referred to as iCarbon. Using a sample of 1,737 firm‐ year observations for 584 nonfinancial firmswith aTwitter account and listed on theU.S. NASDAQ stock exchange over the period 2009–2015, we find that iCarbon is significantly and negatively associated with COE. Our results are consistent after determining the effect of Bloomberg's environmental and environmental, social, and governance disclosure. The findings also hold when using alternative measures of COE and iCarbon.
