A fact sheet from a series developed by IPIECA and OGP to demonstrate the oil and gas industry’s present and future contribution to sustainable development. Prepared in advance of the 2012 United Nations Conference on Sustainable Development (Rio+20). The world’s vast resources of natural gas can help meet growing energy needs.
