Empreinte C 2019
The C footprint of the UMR 6118 Géosciences Rennes has been determined using the tool GES1.5 and adding purchases of consumables and scientific equipment (CPER Buffon) for the year 2019.
The C footprint was 1173 Tons eqCO2 for all the laboratory, which corresponds to approximately 6.3 Tons eqCO2 per person.
Purchases represent 42 % of the total C footprint with 13% for scientific equipments via the CPER Buffon.
Travels represent 41 % of the total C footprint with 25% for commuting to work.
Building (heating and électricity) represents 18 % of the C footprint of the laboratory.
Purchases (without CPER Buffon) were broken down by NACRES category. The main categories were :
A. General supplies (17 Tons eqCO2), of which 50% is for catering or outside food service.
B. Buildings, infrastructure, works (20 Tons eqCO2), of which 42% is related to the removal of radioactive material.
D. Transportation (reservation services), accommodation (43 Tons eqCO2).
G. Laboratory gases (20 Tons eqCO2), of which 37% Argon, 13% Fluorinated gases, 11% Nitrogen.
I. Informatic (60 Tons eqCO2), of which 67% for the purchase of laptops and fixed computers.
N. Chemistry and biology (39 Tons eqCO2), of which 19% for inorganic chemistry products, 12% for filtration consumables and 21% for specialized analytical services.
S. Mass Spectrometry (25 Tons eqCO2).
U. Earth Sciences and Geophysics (15 Tons eqCO2), of which 36% for LIDAR and 36% for other specialized geophysical services.
X. Non-purchase expenses (23 Tons eqCO2), of which 44% for internal invoicing, 22% for conference registrations and 15% for publication costs.
