Sustainable Development and Societal Responsability

The C footprint of our industrialized societies is incompatible with the objective of limiting the increase in the Earth's average temperature to below +1.5°C compared to the pre-industrial period. To meet this objective, global emissions must be reduced to about 24 GigaTonnes eqCO2 in 2030, or 2.8 Tonnes eqCO2 per human being.

The missions of the working group Sustainable Development and Societal Responsability of the UMR 6118 Géosciences Rennes are (i) to determine the C budget of the laboratory using the tool of the GDR LABO1.5, (ii) to inform the laboratory staff of this budget and (iii) to suggest trajectories for reducing our C footprint.

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.
