Philippines prioritizes nuclear in power framework, finalizes 7-phase licensing roadmap
The Philippines has unveiled a new power policy framework that formally prioritizes nuclear energy and other emerging technologies over conventional coal to meet the country’s round-the-clock electricity needs. The government also completed a comprehensive licensing and permitting roadmap for nuclear power plant projects.
Under the new framework, power generation projects will be categorized based on load requirements, guiding developers to align investments with the government’s preferred energy mix. The country is targeting the start of nuclear power operations by 2032. Read more here
OCBC allegedly exploits loopholes to finance coal-powered nickel mining
OCBC has come under scrutiny over allegations that it exploited disclosure gaps when extending loans to Harita Group, without adequately spelling out how financing nickel mining could lead to expanded captive coal-fired power capacity and, in turn, heighten climate risks.
In response, OCBC said its corporate financing complies with relevant regulations, adding that it is unrealistic to require nickel producers in Indonesia to rely entirely on renewable energy at this stage. Read more here

Natural gas in the Philippines: A test case for Southeast Asia’s energy transition
On 19 January 2026, Philippine President Ferdinand Marcos Jr proudly announced the discovery of new natural gas reserves just 5 kilometers east from the original Malampaya gas field off the coasts of Palawan. With an estimated 98 billion cubic feet (2.77 billion cubic metres) of natural gas, Malampaya East-1 was touted by Marcos as a discovery that will “significantly boost the country’s energy supply and strengthen long-term energy security.” But rather than securing the country’s energy future, the discovery underscores the danger of doubling down on natural gas when a faster pivot to renewables is urgently needed.

Rethinking Malaysia’s path to net zero: The role of the Climate Change Bill and carbon markets
As Malaysia prepares to table its long-awaited Climate Change Bill and National Carbon Market Policy in Parliament, the country stands at an important inflection point. For the first time, climate ambition is being translated into a formal legal and institutional framework. This is a necessary and overdue step.
