The environment of doing business has changed in recent years, urging companies to adopt and comply with more stringent anti-corruption norms and standards such as the OECD or the UNCAC conventions. In addition, corporate scandals have proved very costly for companies in terms of image, reputation and sustainability. There may also be some business incentives of preventing and punishing corruption, such as joining the Socially Responsible Investment (SRI) movement. A company that demonstrates anti-bribery commitments may also gain access to bidding lists of companies and public institutions which demand evidence of no-bribes policies.
