The purpose of the paper is the assessment of implementation of Environmental Corporate Social Responsibility (ECSR) concept in Polish food industry in Czestochowa region. ECSR is an important part of the concept of corporate social responsibility (CSR). The food industry has many impacts on the environment and strongly depends on natural resources, that is why companies’ environmental consequences of their functioning are important part of corporate management. The most popular activities in the area of the CSR in Polish enterprises relate to the environmental protection. The analysis of the research results indicates, that 38% of the surveyed enterprises follow the ECSR rules, including mostly large manufacturing enterprises. The ECSR is seen as a tool for creating positive image and reputation of a company on the market and for enhancing the organizational culture of an enterprise.
