Corporate sustainability starts with a company’s value system and a principles-based approach to doing business. This means operating in ways that， at a minimum， meet fundamental responsibilities in the areas of human rights， labour， environment and anti-corruption. Responsible businesses enact the same values and principles wherever they have a presence， and know that good practices in one area do not offset harm in another.
