Learning

Real change begins with awareness. The effects of climate change are no longer distant.

They are unfolding now in our cities, our economies, and our daily lives.

At Ultima Impact, we believe that action starts with understanding.

Our learning page brings together voices from leading experts in climate science, urban resilience, and sustainable finance.

By making this knowledge accessible, we aim to help more people make informed decisions, adapt to what’s coming, and take responsibility for shaping a more sustainable future.

“Climate change affects every aspect of our lives. This series plays an
important role in helping people understand the science and urgency
behind the decisions we face.”

Master of Science (MSc), ETH Zurich
Director, World Business Council for Sustainable Development

“Sustainability must become part of how we think, not just how we act. I
hope this series will encourage more people, especially those outside the
environmental space, to see its relevance in business, in policy, and in
everyday life.”

Doctor of Philosophy (PhD), Monash University
Master of Engineering (MEng), École Centrale Nantes
Assistant Professor, Asian School of the Environment, NTU

“Nature-based solutions are both the simplest and most complex
idea I work with: They are intuitive, grounded in natural processes,
but also layered with nuanced social, ecological, and economic
dimensions. As a professor, I aim to help build a shared
understanding of their strengths and limitations, because raising
awareness is the first step toward mainstreaming these solutions in
policy and practice.”

Associate Professor David Lallemant

Doctor of Philosophy (PhD), Stanford University
Master of Science (MS), University of California, Berkeley (UC Berkeley)
Bachelor of Science (BS), Massachusetts Institute of Technology (MIT)
Associate Professor, Asian School of the Environment, NTU
Principal Investigator, Earth Observatory of Singapore

“We live in a time of overlapping crises. Understanding risk is about
giving people the right tools to plan and adapt, and not just react. I
hope this series helps make that knowledge more widely accessible.”
