The business world is rapidly changing by globalization, the development of information technologies and the increasing concerns for environment protection. Businesses need to be competitive in a market where not only the profit but also the way of attraction, management and marketing strategies used and care for the environment. The paper presents the Romanian business environment in terms of how companies adapt to trends that are imposed by sustainable development and to requirements for environmental protection. Therefore, there are tracked and analyzed some indicators that capture the extent to which Romanian companies are environmentally responsible. The study shows that in recent years, companies in Romania pay more attention to environmental responsibility, using the benchmark of the large corporations which have developed their businesses in Romania and existing EU legislation. However, the differences between Romania and highly developed countries are still high, and to reduce the development disparities, it should continue the efforts to improve the green management policies and strategies adopted by each firm.
