After the Deepwater Horizon oil spill, BP's brand reputation dropped by 50 points compared to a similar company that did not experience such an event, and it did not recover to its original level...

We analyzed the available evidence on BP’s brand reputation after the Deepwater Horizon oil spill, and what we’ve found so far suggests a significant and lasting decline. One assertion, supported by 50.0 studies or data points, indicates that BP’s brand reputation dropped by 50 points compared to a similar company that did not experience such an event, and it did not return to its original level over a seven-year period [1]. This single assertion forms the full basis of our current analysis. We did not find any studies or data that contradict this pattern. The drop in reputation appears to have been large and persistent, lasting at least seven years after the spill. While we cannot say whether this decline was caused solely by the spill or influenced by other factors, the evidence we’ve reviewed consistently points to a major and enduring impact on how the public viewed the company. We note that this conclusion is based on one assertion, even though it is supported by a large number of data points. Without additional studies comparing different time frames, regions, or public segments, we cannot determine whether the trend continued beyond seven years or varied across different audiences. In everyday terms: after the oil spill, people’s trust in BP fell sharply and never came back — at least not within the time frame studied.
