Citigroup has hired two senior dealmakers for its new team focused on clean energy transition, as large investment banks increasingly compete for ESG advisory talent.

Martina Ecker has joined Citigroup's natural resources and clean energy transition group as a managing director, while former Goldman Sachs banker, Kristina Ribas, has joined as a director, according to a memo seen by Financial News. The duo will report into Christopher Tubeileh, Citigroup's head of clean energy transition in Europe, the Middle East and Africa.
