The calculated CO2 footprint of the Future Forward Summit is 20 tons of CO2 equivalents.
This emission corresponds to the emission of 8 return flights Brussels - New York (in economy class). As you can see in this chart
, about 95% of total emissions is due to mobility (mainly participants who came by plane).
Energy consumption of infrastructure: CO2 emissions due to infrastructure used used for the event were kept very low (99 kg CO2) because the event took place in an energy-efficient building.
In addition > 98% of the energy was green electricity. The remaining <2% is natural gas for heating water. The rest of the heating was done by heat pumps and therefore requires no fossil energy.
If we start from a similar (indoor) event that uses conventional energy sources (natural gas for heating and grey electricity for all electricity needs) and with average EPC values, the CO2 emissions for that event are estimated at 1867 kg CO2. This means that the Future Forward scores 95% less than these expected emissions.
By offering only vegetarian meals, CO2 emissions were reduced to 234 kg CO2. If we start from classic meals, which mainly contain more meat, we expect a CO2 emission of 851 kg. That means we've saved up to 73% of kilo's of CO2 on meals. (We take into account the bread lunch, the conference dinner and the meals in Le Phare, not the snacks and drinks.)
