▲ System performance O Transition readiness O Core enablers Sustainable efficiency is improving, but not enough. The current progress is not on track to meet the net- zero emissions target by 2050. The Potential of AI and Digital Technologies AI has the potential to save up to USD 500 billion annually, but it requires strict management of power (Source: World Economic Forum, 2024) Source: World Economic Forum.

Rank Country (2015-2024) ETI score ('24) ('24) (Source: World Economic Forum, 2024) According to Resolution No. 55-NQ/TW of the Politburo on the Strategic Orientation for Vietnam's National Energy Development to 2030, with a Vision to 2045, the specific targets are as follows: The energy savings rate, compared to the business-as-usual scenario, is expected to reach approximately 7% by 2030 and around 14% by 2045. Greenhouse gas emissions from energy activities are to be reduced by 15% by 2030 and 20% by 2045, compared to the business-as-usual scenario.
