Impact of main asset mobilisation (cars, homes)

[OlivierAine]

Is your request related to a problem? Please describe.
How is reflected the carbon cost of owning (or more precisely the cost of mobilizing) assets? For example the construction of a new house or a new car can represent a big part of once carbon footprint

Describe the solution you'd like
I would like that my carbon footprint from my main assets (cars, houses) is displayed otherwise it is misleading and for example someone will prefer to build a new house rather than renovate existing one.

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.
When one login first, there could have a first estimation of carbon emission linked to asset mobilisation in average and then the user can modify the estimation (for example put the number of square meters of once home)

Who do you think would have this data?
ADEME?
