The picture shows a light-flooded part of an office space. Two men can be seen sitting at a desk directly in the foreground, stretching from left to right in the lower third of the picture. The man sitting on the left has short, dark brown and curly hair, a brown-red beard, wears round glasses with black frames and a black shirt. The man to his right has almost black short hair, a brownish beard and is wearing a black T-shirt. Both men are looking at the two monitors on the desk in front of them. Both men are looking at the carbon audit provided by ista on these monitors. To the left of the monitors on the desk is a black printer. To the right of the monitors is a telephone and next to it, on the right-hand edge, two letter trays are stacked. In the background you can see a wall consisting of large windows that stretches from the first left third of the picture to the right edge. In addition, the ceiling, which can be seen in the upper part of the picture, also consists of the same large windows. On the right-hand side of the picture, a dark brown, approximately waist-high room divider can be seen, which bends to the right once. Six plants can be seen on the room divider and behind it.
