This carbon footprint takes into account the reported emissions generated by the activities of the institution over one year and was established according to international standards by Climate Services. Mobility takes into consideration business travels and commuting (on a survey basis). The CO2 impact of food includes the catering of the institution and individual consumption (on a survey basis) during working hours. Nevertheless the collected data of the 2050Today members resulting in each carbon footprint are not yet fully standardized nor entirely complete. Data collection is being progressively harmonized and improved. Therefore direct comparisons between tCO2 / employee among institutions – be it in general or per sector – are not yet possible nor relevant.
According to ISO 14064, the distribution of emissions is done by scopes.
Scope 1 represents direct emissions linked to the consumption of fossil fuels.
Scope 2 represents indirect emissions from the generation of purchased electricity, steam, heating and cooling consumed by the reporting company
Scope 3 includes all other indirect emissions that occur in a company’s value chain (i.e. purchased good or services, business travel, employee commuting).
Mobility : Reported emissions in this category relate mainly to air travel. Flights include flights of WMO’s meeting participants provided by WMO to delegates. The CO2 emissions indicated here refer not only to WMO’s Geneva Office staff.
If we were to give a concrete weight to this carbon footprint, it would represent the weight of the following number of elephants :
(average weight per elephant : 5’000 kilos)
This amount of CO2 was emitted in one year. How many century-old cedars does it take to absorb this carbon footprint in the same amount of time ?
(a 100 year old cedar absorbs on average 25 kg of CO2 per year)
