She previously headed the climate change group of a global law firm and has worked for over 20 years on climate law and finance, including the development of law and policy and its implementation by both governments and the private sector. This experience extends to complex multi-jurisdictional transactions as well as the development of innovative responses to climate change and sustainability problems. Ilona has worked extensively on the development of carbon contracts, carbon funds and carbon transactions in both the compliance and voluntary markets. She also has a deep expertise in advising on natural sinks and forest-based carbon transactions as well as on geological sequestration and the legal frameworks for carbon capture and storage.
