The carbon disclosure project (CDP) encourages companies to disclose their impacts on the environment and to take action to reduce them. Visit its website at www.cdproject.net/en-US/ Pages/HomePage.aspx. 

a. Identify the types of activities it performs and list some companies that disclose their carbon emissions. 

b. In 2012 there were 4112 companies reporting their impacts (compared to 235 in 2003). Suggest why companies would make such voluntary disclosures. 

c. Suggest why the not-for-profit CDP would be more successful at reducing and reporting greenhouse gas emissions than the international Kyoto Protocol.
