Step-by-step explanation:
The major point, which negatively impact the BP's reputation was the CEO Tony Hayward's comportment , who was seen in sunglasses and cap sailing on his yacht off Britain's south coast a few days after the event.
People then has observed the careless person and so lost right from the starting their faith into Hayward. Also, his handling of the Gulf disaster was strewn with public relations gaffs.
When seen under the header Public relations: the second disaster, he became the public face of the enterprise.
An alternative to overcome this reputation loss is to put somebody into place who has more awareness and experience towards the media. So, BP should have engaged in a variety of CSR policies to mitigate the destruction of brand equity.
