I was reading somewhere that Chevron Texaco has been an example of an oil company that cares about the environment. I was intrigued
so I decided to look for something online that confirms this, after all I'm always happy to find some positive stories.
But I can't find anything positive.

The Wikipedia's entry does not say anything.

Then I found this:

Chevron and Texaco, on the other hand, are known primarily for their transgressions on a wide range of social issues. The two companies, for example, have been forced to settle high-profile lawsuits involving gender and racial discrimination, environmental racism and worker safety issues. And, as you would expect with two major oil refiners, their environmental violations have been innumerable.

In fact, investors in the new Chevron Texaco will likely be buying one of the biggest polluters in California history and one of the worst in the world, in terms of spills, leaks and the release of toxic emissions into the air.

The record of these two companies is even worse in the developing world. Both companies' operations overseas have been surrounded by allegations of corruption, exploitation, environmental catastrophe and human rights abuses. True, these abuses are endemic to the oil business in the developing world. Nonetheless, Chevron and Texaco have been implicated from Russia to West Africa to China.

It does not seem to be a very good example to me.

There is a lot of stuff about the mess they've made in Ecuador and the following lawsuit and more here.

But they have this website, so I might be wrong but it looks like this company has a long history of bad environmental management but now they have a greenish website. That's alright then.
I checked the first four pages of my search in Google "Chevron Texaco environment" and this is all I could find.
Does anyone know whether Chevron-Texaco is actually a good example and if yes why I mean have they done anything besides a website and a bit of spin?
