No I don't have any data, because no such data would exist or would be very hard to collate. I can look at the environmental condition and record of any heavily controlled economy or region, or one where nobody has ever really made a profit anywhere. Chernobyl is a grand example. Google is another - they have the profits in order to implement best-practice environmental standards for their operations and buildings, to sponsor world-changing initiatives. Many things that wouldn't be possible without healthy corporate profits. A struggling search engine company wouldn't be trying to power their datacentres with renewable energy or doing many of their other things. I've done enough travel to know the filthiest, most polluted places are those where profitable companies don't exist. Your example of Nigeria just shows that countries mired in poverty and lack of productivity and wealth lack the resources and ability to implement strong environmental controls. Any oil company involved with a leaking pipeline is not going to be as profitable as one with a pipeline that doesn't leak. I personally know people who work in the oil industry in developing nations. The popular image of people like this is of cowboys with no regard for the environment, yet they, and the companies they work for, work hard to get things right. But it's not always possible in a corrupt environment where rewards don't go necessarily to those that work the hardest, but those who have the connections.
