Sorted from the biggest to
the smallest difference
between the two consumers
On vs. Off at night and during lunch hour

emitted by
a regular consumer
C0

emitted by a “climate-
conscious” consumer
The difference represents
C0

emissions that can
be avoided without losing
much comfort.
In this example, C0
2
emitted each day by two
persons living in Munich are detailed, showing two
different ways of fulfilling the same needs: 38 kg of
C0

emitted by an average consumer versus 14 kg
by a more aware one.
