Did you know that access transport to the campus is primarily responsible for the GHG emissions associated with the operation of the university?

The UAB's carbon footprint is the indicator of the greenhouse gas (GHG) emissions * associated with the operation of the university.

In 2019, 72,8% of GHG emissions at UAB come from campus access mobility (42% associated with private transport and 30% with public transport). The remaining 27,8% of emissions are divided into 16% associated with building heating, 7.6% with business travel, 3.2% with waste generation and 0.4% with water consumption.

It should be added that since January 2018 UAB has been buying electricity from renewable energy sources certified with a guarantee of origin (GO) and therefore the emission factor is 0 g CO2 / KWh.

In 2019, UAB's GHG emissions fell by 16% compared to the previous year.

 

* When we speak of greenhouse gases (GHG) we refer to CO2 equivalent (CO2 eq), which includes the six greenhouse gases covered by the Kyoto Protocol: carbon dioxide (CO2), methane (CH4), nitrogen oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulphur hexafluoride (SF6).

Until 2018, the main GHG emissions at UAB came from mobility (access to the campus and business travel) and energy consumption (natural gas and electricity). Since 2018, transport to access the campus has become the main source of GHG emissions.

In the last two years, UAB's GHG emissions have fallen compared to the previous year: in 2019 they fell by 16% compared to 2018 while in 2018 the reduction was 56% compared to 2017. the reason for this large reduction is that since January 2018 UAB has been buying electricity from renewable energy sources certified with a guarantee of origin (GO) and therefore the emission factor is 0 g CO2 / kWh.
