The goal of most sustainability jobs is to promote sustainable practices, encourage social responsibility, create or improve sustainable products and solutions, and plan environmentally-friendly changes. A sustainability consultant helps a company plan and implement more sustainable operations, while the duties of an environmental engineer or scientist include studying, creating, and improving current practices. Sustainability educators work to educate people about the importance of working to protect the environment. Other professionals work in specialized fields such as investment planning for socially-conscious investors.
