Sustainability is a key component of the broader concept of "Sustainable Development." Defined as "development that is able to satisfy the needs of the current generation without sacrificing those of generations to come," "Sustainable Development" has become central when it comes to the environment, community, economy, politics and many other areas. At Deloitte, "Sustainability" focuses on solutions to business operational issues, such as the establishment of a corporate culture, strategic and operational planning, internal management improvement, financial planning, and last but not least, taxation planning.
