In November 2011, Samsung was ranked seventh out of 15 leading electronics manufacturers with a score of 4.1/10.[38] In the newly re-launched guide, Samsung moved down two places (occupying fifth position in October 2010), but scored maximum points for providing verified data and its greenhouse gas emissions. It also scored well for its Sustainable Operations, with the guide praising its relatively good e-waste take-back programme and information. However, the company was criticized for not setting an ambitious target to increase its use of renewable energy and for belonging to a trade association which has commented against energy efficiency standards.[38]
