LPTMC Climactions

The LPTMC associates with the group Labos 1point5, to think about the climatic impact of the lab resarch activities.

The LPTMC, through this action, acts jointly to other labs of Sorbonne University.

Greenhouse gas balance (GHGB)

Researchers of the laboratory have formed a group 'Climactions" and realised the GHGB of the year 2019, using the tool developped by this collective, taking into account:
- Missions (displacements)
- Buildings (electricity, heating, climatisation)
- Commuting,
- IT purchases (stationary computers, laptops, smartphones, computing clusters, screen, printers, hard disks).
- Other purchases (meals, office supplies, books, furnitures...)

The result is 150teC02 for the LPTMC in 2019 (unit: ton equivalent CO2, where the different energy sources are evaluated in terms of CO2 emissions), for 50 people, i.e. 3 teCO2 per person, with an error bar of... 1.2teCO2 per person!

In comparison :
- 9 teCO2 per person per year at LOCEAN (an other lab).
- 2.5 teCO2 per person per year on average in France at work.
- 11.5 teCO2 per person per year in France,
- 4.4 teCO2 in the world, objective <3t.

The pie chart below (2019 balance sheet) is of course subject to multiple errors and should be taken with caution.

The balance sheet for the years 2020-2021 is in progress. Below are the 2020-21 results for positions already assessed:

In 2020, there were few missions (whose money was used for IT purchases).

Home-to-work trips are missing for 2020 and 2021.

Heating and electricity were taken identical to 2019 for the 3 years, but this remains to be adjusted.
