D : Reason In a large Multinational and complex culture organization corporate code of ethics will guarantee  a sustainable environment..

The correct answer is Option C : both a&b are correct

is the answer.

c) both a & b <<<<<>>>>>>>>>>

Option (a) is the best answer.

I would say option 'D' because option A and B are not sufficient towards building a sustainable environment although they are part of the process. The company should a code of ethics which will cover all the aspects of protecting and sustaining the environment.

Facebook New Campus

Well if any one knows about the new Facebook office ??? Facebook has moved into new campus at melno park, California, where on the rooftop, they planted a9 acre garden with around400 trees. With this they hop it will be a safe haven for local birds some of which are on verge of extinct. Imagine a9 acre garden in the concrete structures of California, excellent job done by Facebook management. This is what I called working towards 'building  a sustainable environment' which is part of the Code of Ethics and Corporate Social Responsibility of Facebook. Have a look at the picture which I provide in the link Facebook 'New Campus' above. Thanz.   

• Raise awareness of and demand for better environmental performing buildings, among private consumers, developers and public purchasers;
• Improve knowledge and information regarding resource use and related environmental impacts in relation to buildings in order to support decision making among designers, architects, developers, construction companies, construction product manufacturers, investors, consumers etc;
• Remove the barriers created by different sets of requirements concerning the environmental performance of buildings;
• Improve material efficiency, including the prevention and management of construction and demolition waste;
• Support more intensive use of buildings in order to reduce the need for further built environment (e.g., use empty buildings instead of building new, use buildings for more than one purpose when suitable, build flexible buildings to be adapted to new functions or changing needs when appropriate).

To this end, the Communication focuses on two main areas:

• Influence decision-making (by different actors) along the life-cycle of a building by providing relevant and comparable information regarding environmental performance, through the development of an assessment framework with core indicators
• Increase the use of recycled materials in the construction of buildings, by fostering a better functioning market for recycled construction and demolition waste
