+To provide a rough estimate we may consider that running a '''100 year long''' climate simulation with IPSL-CM6A-LR requires '''150 000 core-hours''' and produces about '''150 kg CO2eq'''. Multiplied by the number of simulations performed (for example 80 000 years of simulation were done for cmip6) this constitutes a non-negligible fraction of the IPSL carbon footprint. This is why we should collectively aim to reduce the environmental footprint of climate modeling.
 
 Adopting good computing practices can contribute towards that goal. Here we attempt to provide such good practices when it comes to using the IPSL climate models. The environmental footprint comes from the computing itself but also from the mass storage hence it is important to target both aspects in our modeling activity.
