The Financial Post reports in its Wednesday edition that at the World Petroleum Congress event last week in Calgary, global corporations and nations issued warnings about the perils of the United Nations-led green energy transition. The Post's Terrence Corcoran writes that the chief executive officers of Exxon Mobil and Aramco said the global economy will continue to need more oil and gas to maintain economic growth and deliver energy to regions, especially developing nations. As reported by Reuters the CEOs said that under the threat of the UN's green energy transition, global investment in new oil and gas exploration and development has hit a plateau, scared off by government policies. Exxon CEO Darren Woods said, "If we don't maintain some level of investment in the industry, you end up running short of supply which leads to high prices." Oil and gas reserves are depleting at 5 to 7 per cent annually, and output will decline if companies stop investing to replace them. Aramco CEO Amin Nasser said, "The current transition shortcomings are already causing mass confusion across industries that produce and or rely on energy." As a result, long-term planners and investors "do not know which way to turn."
