当前的工业化和全球化时代给人类生活增添了许多舒适和奢侈，但也导致了一个令人担忧的情况，即伴随着所有相关活动的环境严重退化。今天，世界经济的整个部门都面临着巨大的挑战，要在日常业务中处理环境问题及其相关影响。不仅商业公司已经意识到环境的重要性，而且在消费者和普通公众中也看到了同样的巨大意识。由于所有这些原因，商业组织已经开始修改他们的活动和战略，以确保我们的自然资源和环境的保护。在此背景下，金融部门，特别是银行可以在促进环境可持续性方面发挥重要作用。可持续性是推动企业战略制定过程的最重要因素之一。虽然我们很晚才认识到任何发展都需要可持续和公平，但积极的方面在于，目前包括金融部门在内的所有经济部门都越来越关注可持续发展。在金融领域，银行、证券经纪公司、信用卡公司以及消费金融公司都采用了绿色业务。对环境可持续性的关注使企业社会责任的概念得到广泛认可。这一概念的潜在好处已引起监管当局、社会、非政府组织、雇员、客户以及国际机构的兴趣。 In this regard, this concern for environmental sustainability by the banks has given rise to concept of Green Banking.
