This paper examines the growing importance of environmental policies in the face of the global warming challenge. Given that companies are largely responsible for producing greenhouse gases (GHGs) which contribute terribly to this crisis, the author looks at the activities of four randomly selected companies that contribute to the problem and then see if they have environmental policies in place to redress the negative effects of their activities. The multinational corporations (MNCs) concerned are General Electric, DuPont, Coca-Cola, and Ford. The methodology applied is basically a literature review as the author looks into their published literature to see if they are committed to protecting the environment. In addition, the author looks at the part that technology can play towards greater sustainability.
