Green purchasing practices clearly reduce energy, usage costs, and waste management. The same applies to social clauses, as they help reduce the public budget allocated to social services, and a subsequent IRS income thanks to tax contributions of new employees. In addition, incorporating social criteria promotes local development, improves living standards, social cohesion, and tackles the most neglected areas.

Responsible procurement practices can contribute significantly to the achievement of strategic goals. Furthermore, they provide support to Socially Responsible Corporations by encouraging those non-SRC to apply a socially responsible management.
