[T]he success of the [Carbon Disclosure Project] in gathering data [on emissions] has led a number of investors to think about [how] to put the data to good use...In 2011, 35 of the CDP’s 655 investor signatories signed up to...[the] Carbon Action, which seeks to engage high-emitting companies...to go beyond disclosing their emissions by committing to take action to cut those emissions..."[M]any companies understand that managing supply chain emissions is very important strategically", [says a representative from PwC]...[I]nvesting in emissions-reduction projects such as energy efficiency measures can save companies money...Another key message that emerges from the initiative is that those companies that set targets perform much better than those without.
