The International Energy Agency released a report May 29 finding that worldwide production of unconventional gas could more than triple in the next 25 years if producers follow certain good conduct rules and address public concerns about environmental risks. The report, Golden Rules for a Golden Age of Gas, concluded that production of unconventional gas, particularly shale gas, could rise to 1.6 trillion cubic meters by 2035, with China a major producer and the United States a net exporter of gas.
