"Green Your Lab" Poster
The most important lab work related tips are summarized in a poster. It was created to hang it on the wall in your lab as a reminder to work greener.
The Calculator
This Excel based tool offers teams the opportunity to calculate their team´s carbon footprint that is related to the laboratory work. Consumables, heating and electricity consumptions can be entered to get a summary of the CO2 emissions of the lab.
Let’s have a look at the different sheets included in the Calculator:
GHG emissions can be classified by scopes that reflect different forms of emission. “Scope 1” relates to direct emissions caused, for instance, by burning coal. This scope is not relevant for our calculation as laboratories normally do not produce any direct emissions. Moreover, “Scope 2” relates to indirect emissions caused by the generation of warmth and electricity.
Getting hands on heating data is usually difficult as data is collected for whole building complexes and not for each respective lab. To measure the power consumption of electrical devices, the actual consumption needs to be measured with powermeters for different settings and durations. Furthermore, the power consumption can also be calculated using performance parameters, but this value can largely differ from the actual value.
"Scope 3" encounts for all other emissions caused related to the project, be it the manufacturing of the used products, the (environmental) cost of their shipping, business trips, etc. It is important to set the boundaries of your calculation at that point. Our team took in account the consumables and chemicals we use in our daily lab routine. The result can be seen as an estimate as not all suppliers provide emission data for their products. Nevertheless, we can identify prominent factors and the proportions of the impact the different factors have.
The unit for measuring the global warming potential of the emitted greenhouse gases (GHG) is CO2, thus the result will be also given in CO2 units. The different other gases occurring are multiplied with a factor that reflects their harmfulness for our climate. For instance, methane is 12.4 times as damaging as carbon dioxide, so one ton of methane accounts for 12.4 tons of CO2.
