Dr Pep Canadell is an eminent world authority on biogeochemistry, particularly the human impact on the Earth’s carbon cycle and ecological processes. He developed integrative methodologies for estimating global carbon sources and sinks, which have become the world standard. 

He is chief research scientist at CSIRO Environment and chief lead investigator in the Climate Systems Hub at the National Environmental Science Program. He is also the executive director of the Global Carbon Project, the most authoritative global source of annual carbon budgets and trend analyses for the major greenhouse gases.

He has been a contributor to the Intergovernmental Panel on Climate Change for 18 years, and his work profoundly influences governments, international climate negotiations, and carbon accounting by non-state actors. In 2021, he was named the 8th most influential climate scientist in the world.

Canadell is an eminent world authority and leader in global biogeochemistry, focusing on the impacts of human activities on the carbon cycle and ecological processes that drive the Earth’s net carbon balance. Canadell has led the development of the dual approach of bottom-up modelling and top-down atmospheric inversions to double-constrain greenhouse gas emissions and carbon budgets. He co-leads regular updates of the global and Australian carbon budgets, which directly inform governments and international climate negotiations. His work has also translated into increased scientific rigour in national greenhouse gas inventories reported by governments and carbon accounting in non-state actors.
