2025 trends: aerosols, oil demand, and carbon removal

Jan 30, 2025
Nat Bullard, co-founder of Halcyon and former chief content officer at BloombergNEF, shares insightful trends from his extensive research on the energy transition. He discusses the unexpected implications of solar geoengineering and aerosols on climate. The conversation examines the surge in U.S. fossil fuel exports and the possible peak of Chinese oil demand. Bullard also critiques the evolving landscape of ESG investing and raises questions about the rapid growth of carbon removal startups versus market readiness and commitment to net-zero emissions.

Quick takeaways

  • Aerosols, despite their cooling effect on climate, present a dilemma as emission reductions could worsen global warming trends.
  • The U.S. has become a dominant energy exporter, but conflicting oil import dynamics complicate its global energy market position.

Deep dives

Impact of Aerosols on Climate

Aerosols have played a significant role in moderating global warming effects, reducing them by an estimated 0.57 degrees Celsius due to emissions primarily from coal combustion and shipping. This information highlights a dual impact of human activity on climate: while greenhouse gases lead to warming, aerosols have inadvertently induced a cooling effect. As countries reduce aerosol emissions for environmental reasons, the absence of this cooling could exacerbate warming trends. Specifically, high altitude particulate pollution sourced from shipping lanes demonstrates how interconnected global regulations can influence climate outcomes.
