In this episode of the All Things Sustainable podcast, we explore the geopolitical and macroeconomic issues impacting sustainability, energy and climate strategies in 2026.

We speak to Carlos Pascual, Senior Vice President and Head of Geopolitics and International Affairs at S&P Global Energy and a former US Ambassador to Mexico and Ukraine.

Carlos describes a fragmented geopolitical landscape marked by significant uncertainty about the direction of global climate policy, action and finance — leaving progress largely in the hands of the private sector.

"We have huge changes ahead and look for the private sector to have to play a much more central role in the overall momentum on clean technology and investments in renewable energy," Carlos says.

We speak to S&P Global Ratings Global Chief Economist Paul Gruenwald to understand the macroeconomic factors influencing sustainability. Paul says AI is the dominant story for 2026.

"We're seeing great numbers out of data center and AI-related investment, but almost everything else is flat," Paul tells us.

To understand the outlook for climate change and the growing importance of adaptation alongside mitigation efforts, we speak to Dr. Terence Thompson, Chief Science Officer at the S&P Global Climate Center of Excellence. He explains how advances in climate science are helping to better understand the probability of climate hazards.

"Getting at that probability is really key to making those kinds of very practical decisions about how do we allocate limited resources to cope with climate change and adapt to it," Terence says.

And to understand the outlook for the energy transition, we speak to Roman Kramarchuk, Head of Integrated Narratives and Policy Analytics at S&P Global Energy. Roman explains how the world is balancing growing energy demands with sustainability priorities in an increasingly fractured global landscape.

"There's a big regional story here, and this is a regional story that plays out both in the technology, in the supply chains, and in the geopolitical side," Roman says.
