|
[A] Restated down from 323 to 300 thousand tonnes due to calculation error in one of our operations in Nigeria. |
|
|
[B] Data error in 2005 Report. |
|
|
[C] Restated for all years to exclude cooling water that travels only once through the plant and is returned to the environment. |
|
|
[D] Increase in 2006 mainly due to disposal of non-hazardous waste after the 2005 hurricanes in the Gulf of Mexico. Also due to the inclusion of hazardous and non-hazardous soil into these categories by some downstream operations. |
|
|
[E] We continue to score highest in our industry for “environmental responsibility” in the Reputation Tracker survey conducted on our behalf in 13 of our major markets, by the polling agency Ipsos MORI. However, in the 7 markets we have in common with our nearest international competitor, special publics score us marginally lower – 3% – and the general public rate us on a par. |
