Quotes

• I believe we have an obligation to use our technology to minimize the environmental impact of our operations and our products. What disturbs me is not the ever-present and perfectly valid public requirements for health and safety in the use of energy. Rather I'm distressed by a growing public conviction that oil does not . . . and can not . . . meet those requirements. http://www.chevron.com/news/archive/chevron_speech/1994/94-2-8.asp

• A 1991 poll showed that 74 percent of Americans think the greenhouse effect is a problem. And 41 percent believe it's a serious problem. Some people in our industry tend to simply wave the issue away by saying that the threat is unproven. That's true; but it's not an appropriate response. http://www.chevron.com/news/archive/chevron_speech/1994/94-2-8.asp
