2. 2 The Global Energy Challenge The pursuit of economic growth and a better quality of life in the developing world is driving global energy demand. New supplies of reliable, affordable energy are needed. Meeting this demand while managing emissions is an enormous challenge…

18. 18 Addressing the Risks of Climate Change ExxonMobil takes the issue of climate change seriously, and the risks warrant action. Climate remains today an extraordinarily complex area of scientific study, but the risks to society and ecosystems from increases in CO 2 emissions could prove to be significant. Despite areas of uncertainty, it is prudent to develop and implement strategies that address the risks, keeping in mind the central importance of energy to the economies of the world The challenge going forward is to provide the energy the world demands while reducing greenhouse gas emissions.
