LNG buyers increasingly expect a product that complies with various current and anticipated global regulatory requirements as part of long-term contracts. Whether this is reflected in new structures to confirm the date on which commercial operations commence, or requirements for the use of responsibly sourced or certificated gas for the production of LNG, key terms and conditions that had become standard in US LNG sale and purchase agreements are evolving to meet new global market needs. This paper will examine the evolution of key contract terms and the impact on the gas and LNG value chains, as well as the complexity involved in contracting for a globally traded commodity where the global market requirements and conditions vary from region to region.
