Our strategic approach to sustainability

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 ESG policy

Paving the way to integrate sustainability in the way we work and influence our decision-making on strategy, capital allocation, operations, governance, and culture is our ESG Policy, with the aim to deliver long-term value for all our stakeholders.

As part of our sustainability commitment, we implement the Environmental and Social Management System (ESMS) to manage E&S risks and impacts throughout the life cycle of our projects.
