At ACS, we have been evaluating and measuring our carbonfootprint since 2019, and working hard to reduce our emissions ever since – but this takes time and a dedicated team. Our Sustainability Team has been carefully assembled with employees from a number of different departments within ACS. This spread of representation across all operations allows us – where possible – to more easily identify and implement emission reductions.
The Sustainability team meets regularly to discuss our progress, and we held a workshop earlier in the year to explore additional ways to achieve our Net Zero ambitions. Our findings are being worked into a Transition Plan towards Net Zero, which we will communicate towards the end of the year.
In the meantime, we are very proud to share some of our initial reduction successes. Most notably implementing a travel policy to travel by train, or shared electric road transportation, to our clients’ projects which are less than 600kms from Amsterdam. We have also moved our head office to a more energy efficient building, and transitioned our fleet of sales vehicles to EVs, which can be charged at our own charging poles at the head office. Our Utrecht office is almost completely self-sustained, with solar panels on the building to charge the electric sales vehicle, and also our first electric delivery van.
So, we feel that we are well on the path towards Net Zero, but until we can achieve our ambitions, we need to offset our residual emissions. These are calculated with the help of our sustainability consultants, Anthesis (formerly the Climate Neutral Group), who also produced ACS’s 2024 CO2 emissions footprint report, which details the amount of tCO2e (tonnes of carbon dioxide equivalent) ACS produced in 2024. Anthesis then advised us regarding the offsetting possibilities for these residual emissions – carefully selected climate projects that combine solutions for carbon reduction with broader social and environmental benefits..
Anthesis recommends using the Oxford Principles for Carbon Offsetting as a strategic framework, emphasizing transparency, additionality, and sustainable development to create a comprehensive and impactful offset strategy. They work with independent parties who assess a number of projects and ensure that they are of good quality, meet the highest market requirements, and that 1 carbon credit truly equals 1 ton of CO2 removed from the air. These carbon credits are also either Verified Carbon Standard or Gold Standard.

Certificate confirming our carbon credit investments
For 2024, ACS chose Gold Standard carbon credits supporting Cookstove Projects in Africa, which help reduce CO2 emissions and biodiversity loss while improving people’s health by investing in the local production and distribution of cookstoves. The cookstoves’ efficient combustion system reduces wood use by 50% compared to traditional cooking methods. The cookstoves also help combat deforestation and reduce the amount of greenhouse gases released into the atmosphere. They also improve indoor air quality and reduce neck and back pain from carrying wood, and improve living conditions by spending less time gathering firewood and cooking.
In addition to the cookstoves project, ACS also chose to invest in a VCS Standard project closer to home – the Dutch biogas project, which aims to increase sustainability in the sector by fermenting manure and residual products from the food industry through biogas installations. The goal is to produce milk and meat more sustainably and reduce methane emissions. In addition, the plant can convert animal protein products into biogas and plant feed, while the residual product is sold as a fertilizer substitute.

As the European industry leader in creating impressive congress spaces, ACS audiovisual solutions knows how to transform an empty exhibition hall into multiple fully-equipped session rooms, that can accommodate from 200 up to an impressive ten thousand attendees.
At ACS, we understand that each event is unique, so our skilled AV designers produce highly-detailed technical drawings that simulate any congress environment. With meticulous attention to detail – every element within each room is carefully selected and positioned to assure an optimal congress experience for every participant.
ACS has a number of acoustic solutions that reduce unwanted noise, while enhancing the clarity of each speaker’s message. We offer various sound-damping material including curtains, carpets and furniture and our commitment to innovation means that we continuously refine our approach to sound resonance within congress spaces. Through extensive testing and development, we are proud to present our latest groundbreaking solution; the Sound Absorbing Cylinders.
These cylinders significantly enhance acoustics by absorbing unwanted noise and amplifying what matters most – the voices of the speakers.

Each Sound Absorbing Cylinder has been crafted from Petfelt, which is made from recycled plastic bottles. So, in addition to the acoustic performance of these cylinders, they also add a sustainable value to any congress session room.

ACS has been measuring its CO2 emissions since 2019, and working with Anthesis to calculate its carbon footprint each year. When calculating a footprint, it is important to define the organisational and operational boundaries, which then relate to which emissions should be included in the footprint. There are guidelines for measuring the different emissions under the Greenhouse Gas (GHG) Protocol Standards. This GHG Protocol uses 3 scopes to distinguish between direct and indirect emissions.
Scope 1, includes direct emissions from sources that are owned or created by us. These emissions are seen as being generated by us, from ‘our own chimney’, for example if we burn gas to heat our buildings.
Scope 2, includes indirect emissions from the generation of purchased energy, such as electricity. These emissions are generated elsewhere (i.e. at the energy supplier), but are directly related to your company. This scope also includes the energy used to power our fleet of electric vehicles.
Scope 3, includes all other emissions from within your value chain; including business travel (flights, hotels and cars), employee commuting. There are also upstream and downstream emissions in the supply chain. Upstream and goods and services coming into the company and downstream are goods and services leaving the company, which mainly includes transportation & distribution.
Once we established which emissions should be measured, we started to collect the data. This data included how many litres of diesel/petrol was used, the amount of kWh of electricity used across the year, and how many KMs were flown. This data was uploaded to the Anthesis (Climate Neutral Group) online programme, where the date was checked and our total emissions for the year were calculated. Anthesis then created a CO2 emissions footprint report, which showed how many tCO2e (tonnes of carbon dioxide equivalent) we used in 2023.

In previous years, ACS has offset our residual emissions through certified efficient cookstove projects in Africa, through African Cookstoves BIX credits. For the 2023 footprint, ACS decided to continue with this offsetting option, and also include Biogas projects in the Netherlands; Aside from offsetting all of our residual emissions through VCS Dutch Biogas credits.
Agricultural dairy cooperatives and livestock farms have had a profound impact on the Dutch landscape. This biogas project aims to increase sustainability in this sector by fermenting manure and residual products from the food industry via biogas installations, which reduce greenhouse gas emissions, including methane, a major cause of climate change.

ACS GIVES ADDITIONAL DONATION TO JUSTDIGGIT
ACS is proud to announce their additional donation to the Justdiggit programme. Increasing the total amount of land that ACS is committed to regreen to 900,000 m2.
Justdiggit’s mission is to cool down the planet by regreening African landscapes. ACS has been in partnership with Justdiggit since 2022, and is comitted to supporting their efforts in Kuku, Kenya.
HOW JUSTDIGGIT WORKS
Justdiggit believes that 37% of the climate problem can be solved by applying nature-based solutions. Justdiggit works closely with local partners and communities to restore dry areas of land. Proven regreening techniques include rainwater harvesting (digging bunds), tree restoration (Kisiki Hai / FMNR), and developing grass seed banks. All of their projects are owned and implemented by communities that live off the land.
These projects give nature a hand in bringing back vegetation in degraded areas. The presence of vegetation keeps the soil healthy and fertile, which allows plants and trees to keep on growing. When vegetation returns, it can help to restore an entire area and in turn the community it supports!
