Honoring the Life and Legacy of Dr. Toufiq A. Siddiqi
Dr. Toufiq A. Siddiqi (1937–2023), the founder of GEE-21, was a trailblazing environmental scientist and policy expert whose work bridged energy, climate change, and sustainability. A respected voice on the global stage, Dr. Siddiqi was a Lead Author for the Intergovernmental Panel on Climate Change (IPCC) Report, whose collective contributions to climate science were recognized with the Nobel Peace Prize in 2007. He also consulted for numerous United Nations agencies, the World Bank, and the Asian Development Bank. His leadership extended to his tenure as Past-President of the Hawai‘i Academy of Science, where he championed scientific inquiry and innovation.

As Chairman of the Board of GEE-21 (Global Environment and Energy in the 21st Century) and Adjunct Senior Fellow at the East-West Center in Hawai‘i, Dr. Siddiqi dedicated his career to addressing some of our most pressing environmental challenges. GEE-21 held its first full board meeting in Honolulu in August 1998. He also served as Affiliate Graduate Faculty in the Geography Department at the University of Hawai‘i, nurturing the next generation of scholars in the fields of energy policy and environmental science.
Dr. Siddiqi’s career spanned decades of impactful contributions, including serving as the Regional Advisor on Energy for the United Nations Economic and Social Commission for Asia and the Pacific (ESCAP). Starting at the East-West Center in 1979, he built the first environmental research projects between China and the USA, a lasting relationship he carried over into GEE-21. During his 18 years at the East-West Center in Honolulu, he pioneered a groundbreaking program in 1979 on “The Environmental Dimensions of Energy Policies,” one of the first in Asia and the Pacific to explore the critical intersections between energy and environmental concerns.
As a trusted leader and mentor, Dr. Siddiqi’s legacy endures through the countless lives he touched and the initiatives he spearheaded to advance environmental stewardship. His pioneering spirit and dedication to a sustainable future will be remembered and celebrated for generations.
