Sustainability Lead Herman Calleja has been selected as a lead author for the upcoming Seventh Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), one of the world’s most authoritative scientific resources on climate change.
IPCC reports are global efforts, bringing together thousands of scientists, experts, and governments to inform climate action and policy at the highest levels.

Calleja’s selection is a testament to his scientific leadership and deep commitment to tackling one of the defining challenges of our time. He will serve as a lead contributor to a chapter focused on adaptation in human settlements, infrastructure, and industrial systems—exploring how cities, communities, and industries can adapt to a changing climate while building resilience for the future.
