As in previous years, we also provide an intermediate score of the carbon footprint or the CO2 footprint this year. The footprint is divided into 3 sub-sections, entitled the scope 1 up to 3.

Scope 1 includes all direct emissions, such as the consumption of natural gas, petrol, diesel, etc.

Scope 2 includes all indirect emissions, such as electricity consumption and travelling by train or aeroplane.

Scope 3 includes all indirect emissions that are not included in scope 2, such as the transport of employees who come to work with their own car, all waste fractions and paper consumption.

We close the first half of the year at the end of June and compile an intermediate score. This way, we can detect more quickly whether we are making sufficient efforts to meet our objective. Our total emissions for scope 1 and 2 (see table below), calculated up to and including June 2018, amounts to 3.125 TCO2e. If this trend continues, we will have an absolute emission that will be higher than in 2017. But, of course, the emissions cannot only be viewed as an absolute. In the evaluation of a full year, we also compare the emissions with the turnover and with the number of employees.

If we look at our biannual emissions in detail, we see some differences compared to 2017. The emissions in scope 1 (see table below) show a slight increase compared to what is expected. The consumption of the ships and Kallo is higher because of the increase in activities in 2018.

If we look in detail at scope 2 (see table below), we notice a large increase in emissions in Kallo. The reason for this is that, in all the previous years, the certification body has allowed us to count our green electricity as being neutral, which has not been permitted since 2018. That is why the electricity consumption on the sites and in Kallo is counted in full, as in 2013 and 2014.

In conclusion, we also provide an overview of the CO2 reduction measures and the impact thereof as a result.

HERBOSCH-KIERE  is member of the VBA Green Board, the association of Belgian contractors.

The Green Board is an environmental working group that informs the members about the new norms, legislations and tools. Environmental issues are examined and initiatives are launched. One of the main topics is the reduction of CO2.
