Enterprises are looking for improvements in their processes, products and services, causing them to become more complex mainly due to the amount of information and requirements involved. At same time, governments and costumers are more conscious about Sustainable Development requirements. Enterprise Architectures supports the analysis, simulation, automated systems projects, distribution of responsibilities and authorities, aimed at reengineering or improvement of companies processes. However, they do not seem to contemplate the requirements related to Sustainable Development in a systemic and integrated way. This paper discusses the derivation and incorporation of Sustainable Development requirements into Enterprise Architecture Frameworks (EAF). Then, this works presents some initial guidelines to extend components of GERAM with ISO standards and frameworks related to sustainability.
