Oil & Gas Connectivity, Security, and Sustainability (OGCSS)

Oil and Gas Connectivity, Security, and Sustainability (OGCSS)—formerly called the Trans-ASEAN Gas Pipeline (TAGP)—reflects ASEAN’s broadened focus beyond pipeline infrastructure to encompass wider oil and gas cooperation, as well as energy security.

With the region’s energy demand expected to increase 2.6 times by 2050, oil and gas are expected to remain the largest contributors to the region’s TPES. Oil supply, in particular, is projected to record the largest absolute increase among all fuels, rising by about 321.3 Mtoe between 2022 and 2050. This underscores the growing importance of ensuring reliable connectivity, security and sustainability across the oil and gas value chain.
