European Green Deal policies and national climate and energy targets are leading to significant regulatory interventions that are having a major impact on the overall operations and decision-making of the companies and organizations. What do companies think about this and what is their social acceptance and attitude towards the newly imposed measures and energy efficiency? In this study, 711 companies are surveyed to determine their awareness, attitude and knowledge about climate policy and energy efficiency. The results show that company size influences overall understanding and attitudes towards climate and energy efficiency measures. The results show the most common energy efficiency measures implemented by companies that have contributed to significant energy savings. Media and emails are rated as the most common means of communication used by companies to obtain information on energy efficiency.
