As part of Carnival Corporation & plc's family of cruise brands, the company has set a goal to reduce its carbon intensity by 20 percent by 2026 compared to 2019. The first phase of the program will be a major overhaul of the Sphinx ships AIDAdiva, AIDAbella and AIDAluna in 2025 and 2026. The focus will be on a new interior design of the ships. In addition, technical equipment and systems will be updated. The ships in the Sphinx series, which also include AIDAsol, AIDAblue, AIDAmar and AIDAstella, were commissioned between 2007 and 2013.
