  Over the years ethical, social and environmental accounting (ESEA) has become
a common practice among responsible organisations. ESEA entails assessing and
reporting organisations" performance on environmental, social and governance
topics. In this report, we present a textual grammar for specifying ESEA
methods. With the grammar ESEA models can be created. Such models can be
interpreted by our open-source, model-driven tool, called openESEA. The report
presents the metamodel of the grammar, the grammar itself, and explanations of
each grammar primitive.
