The development witnessed by the world and the changes in the global economy imposed on organizations to adopt environmental responsibility. Therefore, major international organizations seek to develop strategic plans to preserve the environment and reduce the use of polluting resources which led to increasing its profitability, increasing its market share and maximizing its relationship with its competitors and customers. Current study aimed at examining the role of environmental responsibility on increasing organizational market share within four main variables which are (internal operations, values, environmental policies and management awareness). A questionnaire was adopted in order to gather data from a sample of (321) marketing and sales managers within industrial sector in Kuwait. Utilizing descriptive statistics, linear regression and multiple regression through SPSS; results of study accepted the main hypothesis and expressed the ability to environmental responsibility to boost market share. In addition to that, it appeared that among chosen variables internal operations seemed to have the highest influence in terms of decreasing production costs and giving the chance for organizations to increase quality and lower prices in order to attract more customers, meet competitors thus get a higher market share. Study recommended that expecting a higher market share is not unlimited; rather it is dependent on many monopoly laws, so organizations must adopt the foundations for increasing market share in a logical and thoughtful way.
