Cathrine Hambro assists industrial companies and the waste disposal industry with pollution legislation, licensing issues, and contract preparation. Her long-term experience as an adviser to these industries has given her a good commercial and strategic understanding, which is reflected in the legal advice she provides.

Cathrine also assists Norwegian and international organisations with advice and litigation support related to environmental and climate issues. She was counsel in the so-called climate lawsuit, which was litigated before courts of three instances, most recently before the Supreme Court in 2020. She is now one of two counsels representing the parties that have brought the case to the European Court of Human Rights in Strasbourg, which has agreed to hear the parties’ application.

Cathrine is zealous in her field. She participates in discussions regarding the legal aspects of sustainability and circular economy and is a member of the Norwegian Bar Association's law committee for environmental law. Her social engagement is instrumental both in her work on climate and environmental law, and in her involvement in legal protection issues raised by electronic identity fraud. Through lawsuits and negotiations, she has resolved several disputes concerning liability following bank-ID fraud.

In Finansavisen's lawyer peer review, Cathrine is ranked in the category Climate and environmental law.

Cathrine regularly lectures on sustainability, the environment and climate.
