Rajendra K. Pachauri led the Intergovernmental Panel on Climate Change (IPCC) from 2002 to 2015, overseeing the scientific foundations of the Paris Agreement. His tenure encompassed the fourth and fifth assessment cycles, marking a period where human-induced climate change shifted from a peripheral academic concern to a critical global policy priority under his leadership.
Early Career and Education
Born in Nainital in 1940, Pachauri attended La Martiniere Lucknow before joining the Special Class Railway Apprentices scheme. He worked at the Diesel Locomotive Works in Varanasi early in his professional life. Later, he moved to the United States to study at North Carolina State University, where he earned an MS in Industrial Engineering in 1972 and a PhD in 1974. His doctoral thesis focused on dynamic modeling for electrical energy demand.

Take the IQ test →Institutional Leadership
Pachauri joined The Energy and Resources Institute (TERI) in 1982, assuming the role of director and leading the organization for over three decades until 2016. Throughout his career, he held various advisory roles, including positions with the World Bank, the United Nations Development Programme, and the Economic Advisory Council to the Prime Minister of India. He also served on the boards of the International Solar Energy Society and the World Resources Institute.
The IPCC Tenure
Elected as chairman of the IPCC in April 2002, Pachauri directed the panel during its receipt of the 2007 Nobel Peace Prize. He frequently highlighted the risks climate change posed to vulnerable populations, including water scarcity and population displacement. His tenure ended in 2015 following legal allegations of sexual harassment, though he was exonerated by a court in 2022.
Sustainability Initiatives
Beyond his institutional roles, Pachauri focused on practical energy access through the Lighting a Billion Lives initiative, which he launched in 2008. The program provided solar energy to remote regions in India, including the Sundarbans, the Thar Desert, and the state of Bihar. A strict vegetarian, he often cited environmental impacts as a primary reason for his dietary choices.
