Nowadays, climate change is the biggest environmental challenge that the world faces. The average temperature is increasing because of the so-called greenhouse effect, which means that the amount of greenhouse gases in the atmosphere, especially CO2, is dramatically increasing.

Therefore, the reduction of our CO2 emissions is one of the main challenges in our environmental sustainability policy.

In 2013, our CO2 emission level was calculated for the first time: 4,673 tons of CO2, an amount that equals driving 649 times around the world in an average car, 1,792 times flying to and fro between Brussels and New York, the yearly emission of 234 Belgians, etc.

This calculation was based on two scopes of the CO2 performance ladder: scope 1, which is the direct emission through fuel use, and scope 2, which consists of the indirect emission via electricity consumption. Also, the amount of waste, traffic from home to the workplace and the use of paper have been taken into account.

Sites, floating equipment and mobility are the main elements in our CO2 emission level, representing respectively 41%, 30% and 22%. The main source of CO2 emission is the fuel use.

During spring 2015, Herbosch-Kiere committed to obtain level 3 of the CO2 performance ladder. This ladder is a Dutch instrument to encourage companies that participate in public tenders to improve their CO2 consciousness both in their own management as in the execution of projects by energy saving, efficient use of materials and using sustainable energy.

We aim to reduce our CO2 emission by the end of 2017 by 6% compared to the reference year 2013.

In order to achieve this goal, we planned this actions starting in 2015 and continuing during the following years: LED lights in our offices, replacement of old heating installations, action as to tyre pressure, purchase of energy efficient computer screens, use of energy-saving company cars, more sites connected to mains current instead of using fuel oil through generators, special antifoul on our vessels and use of green power in our offices.

To ensure a good follow-up, the results will be semiannually and annually calculated and evaluated. 

To reflect the results of our efforts, we differentiate between the emission of the floating equipment and the emission of the other consumers.

Evolution of floating equipment emission

Our vessels Albatros and Atlantis are the main fuel oil consumers. In order to optimize the Atlantis’ consumption when sailing, we applied a special antifoul which theoretically reduces the consumption by 4%. As the fuel is not always supplied by Herbosch-Kiere, the registered consumption fluctuates noticeably.

Because the Atlantis is the main fuel oil consumer, the antifoul was checked, cleaned and reinstalled in order to garantuee the reduction of CO2.

Evolution of other equipment emission

One of the planned actions was and still is to reduce the electricity consumption by connecting as many sites as possible to green mains current. This technique already caused a consumption reduction compared to the reference year. A reduction that will continue after puchasing 100% green energy, for the office as well as for the sites.

When purchasing new company cars, we pay attention to the maximum CO2 emission level. For example, in 2013 we started with an average emission of 130g/km and in 2016 we achieved an average emission of 118g/km, an improvement of 9,23%.

We still have planned to start using natural gas instead of propane to heat our offices and our workplace, which will also reduce our emission level.

In addition to the plan of action we also acquired fuel efficient cranes. They improved our emission with 35%.

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.
