We place ESG and sustainability
at the heart of what we do –
for future generations
Our strategic
sustainability approach
Sustainability is integral in ACEN’s business strategy. It is at the core of who we are and what we do. As one of the fastest growing renewable energy platforms in the Asia Pacific, we thrive on creating the most value for both society and our business.
As we grow our renewables portfolio, we continue to deliver on our climate commitments. The successful implementation of our Energy Transition Mechanism puts us in a position to play a leading role in the energy transition in the region.
We take pride in the partnerships we made in December 2023 with the Rockefeller Foundation’s Coal to Clean Credit Initiative and the Monetary Authority of Singapore to implement the world’s first coal-to-clean credit pilot project complement our early coal retirement for the 246 MW SLTEC coal plant by 2040.
The transition credit initiative will potentially accelerate the transition of coal to cleaner technology as early as 2030. If successful, this can be scaled up and replicated by other coal fired power plants not only in the Philippines but across the globe.
In embracing our role as a catalyst for sustainable change, we recognize that our journey is one that we cannot do alone. Our collaborative efforts, innovative spirit, and commitment to sustainability are the driving forces in making a positive impact on the environment and society.
Through the integration of our ESG principles into our operations, we are not only redefining the future of energy, but also laying the foundation for a more sustainable tomorrow, where energy not only powers our economies but also safeguards our planet for generations to come.

Our materiality process
To determine economic, environmental, social and governance issues that are important to ACEN and our stakeholders, we conducted a series of materiality exercises in collaboration with an external consultant and business unit heads. identifying topics that are important to ACEN both financially and from an external impact perspective.
Our material ESG issues were updated to reflect our engagements with investors, rating institutions, and other stakeholder concerns regarding ESG. This was supplemented by research activities on the latest developments around sustainability reporting frameworks and industry-specific sustainability issues. Roadshows were also conducted with our leadership team and the board-level Sustainability Committee to validate our material ESG issues and identify strategic action plans around key ESG issues moving forward.
We conduct the materiality process every 1-2 years to ensure that material ESG topics and our ESG strategy are continuously updated to ensure relevance to our stakeholders.
