How 2025 redefined responsibility and sustainable living

The year 2025 was not just a time for reflection.

- By MILLIE MANAHAN

It asked many of us to pause, reassess and awaken—awakening to responsibility, to boundaries, to belief and to the realization that sustainability is not a distant ideal, but something shaped daily by how we live, work and choose.This shift did not happen by accident. A study done by Hiroshima University, notes that younger generations — defined broadly as those in their late teens to early 30s — are more open-minded, proactive and intentional about sustainability than previous cohorts. Research shows they are not only more inclined to support environmentally responsible products and careers, but also more willing to change everyday behaviors in pursuit of climate goals and more equitable systems. Increasingly, the push toward sustainable living is being led by emerging voices.

For this year-end feature, I spoke with a small circle of friends and colleagues — people whose lives intersect with purpose in different ways — and asked them to share one key lesson from 2025, how they plan to carry it into 2026, and one eco-conscious habit they intend to continue or begin in the new year.

What emerged were honest reflections that serve as a reminder: meaningful change often begins quietly.

An awakening to responsibility

It felt fitting to begin with someone who has long been at the forefront of the sustainability conversation—Len Gatbonton-Amadora, section editor of the Manila Bulletin's Environment and Sustainability section.

When asked about her biggest lesson from 2025, her answer was refreshingly candid.

“For me, 2025 was an awakening year,” she said. “I realized that sustainability—though often talked about—had never really made it into my daily priorities. I was taking it for granted.”

That realization marked a turning point. As she looks ahead to 2026, she is choosing to be more mindful and deliberate, treating sustainability not as an option, but as a responsibility.
