Environmental Accounting and Reporting in Fossil Fuel Sector : A Study on Bangladesh Oil, Gas and Mineral Corporation (Petrobangla)

Petrobangla is the sole responsible organization to maintain the fossil fuel sector in Bangladesh. It is accountable to next generations for oil, gas and other natural resources. It is necessary to ensure optimum use of these resources. Development activities cannot be sustained if these resources are depleted through wasteful use. This study indicates that Petrobangla takes many initiatives to provide environment-friendly energy in the economy. Environmental Accounting and reporting is the emerging concept in Bangladesh, although many countries in the world, either developed or developing, are practising environmental accounting and reporting in their fossil fuel sector. Since the need for fossil fuel is likely to increase, especially in developing countries [where the supply of these resources insufficient], the accounting and reporting of these resources have become inevitable.Environmental Accounting, Fossil Fuel, Environmental Reporting
