Context. The Great Nebula in Carina is one of the most massive (M�; total >25 000 M�) star-forming complexes in our Galaxy and contains several stars with (initial) masses exceeding �100 M�; it is therefore a superb location in which to study the physi cs of violent massive star-formation and the resulting feedback effects, including cloud dispersal and triggered star-format ion. Aims. We aim to reveal the cold dusty clouds in the Carina Nebula complex, to determine their morphology and masses, and to study the interaction of the luminous massive stars with these clouds. Methods. We used the Large APEX Bolometer Camera LABOCA at the APEX tel escope to map a 1: 25 � � 1: 25 � (b 50� 50 pc 2 ) region at 870� m with 18 00 angular resolution (= 0.2 pc at the distance of the Carina Nebula) and an r.m.s. noise level of�20 mJy/beam.
