Measuring Performance: Deutsche Post DHL Performance to Date.

Deutsche Post DHL have gone to great lengths to describe how they calculate their Carbon Emmisions and Efficiency Index . The company set up, in 2010 a dedicated Carbon Accounting and Controlling Department. The department is responsible for reporting the index following Greenhouse Gas Protocol and ISO 14064 standards.

Auditing of the performance data has been assigned tp PWC (Price Waterhouse Coopers) who state in their report :
Based on our assignment, selected web-pages and performance indicators presented on the "Responsibility" web sites of the DPDHL corporate website www.dp-dhl.com have been subject to our assurance engagement. Where our assurance engagement covered full web-pages these are labeled with the symbol “√”, while the symbol “[√]” labels web-pages on which only selected information - as 
specified at the end of the respective web-pages - have been subject to our engagement.

The Performance Summary web page does not bare the “[√]” label so, I deduce, that this is not PWC assured information. What is interesting to note is that the performance index is already at 88 (2020 goal = 70). Is this surprising? The company is reporting that they are almost half way to achieving their goal to reduce carbon emissions by 30%.

Why did PWC not audit the all important performance index? Maybe it was so complex a task they could not complete the audit in time or maybe DPDHL determined that these were web pages not selected for audit.

I will endeavor to secure a comment from PWC and DPDHL to help answer these questions.
