McDonald’s, which is often blamed for promoting unhealthy meal choices, is doing its best clearing its image by improving food standards and adopting greener choices in its business. The biggest fast-food chain in the world has issued the 2012 Global Best of Green report, which highlights 90 examples of its environmental best-practice innovations. The 46-page illustrated report is spanning across eight categories—energy, packaging, anti-littering, recycling, logistics, communications, green building, and greening the workplace—and tells about the company’s achievements in each of them.

Social change, efficient usage and conservation has become the key themes of a range of initiatives running under brands’ banners—and Toyota can be named one of the most active companies in this game-changing movement due to its numerous initiatives of this kind. Toyota is adding a new initiative to the list by launching Spring Greening Challenge, a Facebook app that features weekly conservation challenges, data on the impacts of your personal domestic green choices and offers a chance to win money for participation. The new application has been unveiled as part of TogetherGreen, a conservation alliance between the National Audubon Society and Toyota, which was created for fostering public awareness and continued involvement in conservation issue.
