Since the end of the 1990s, many companies have been getting explicitly involved in promoting good governance. The oil and mining sector is very prolific in this regard with at least three of the largest mining and oil companies having programs to promote public accountability at the international, national or local level. Initiatives to foster transparency, citizen participation or the strengthening of government capacities in which companies play an important role multiply. Why are for-profit organizations, whose aim is to extract natural resources and make profit, willing to invest time and money in promoting governance? Which factors allow for some companies to get more involved than others? The present chapter intends to answer this question. Based on a case study in Colombia and more than 40 interviews with companies' employees, public servants and societal leaders, I analyze the motivations, interests and values that led an extractive company to engage in these types of initiatives.
