EARTH works in accordance with the Dutch Archaeology Quality Standard and is authorised to implement all stages of an archaeological investigation.
The environment matters to EARTH and we search actively for ways to respect it. As the first archaeological research agency we have been certified with the Dutch CO2 performance ladder level 3. We see certification as an ongoing process in which we are continuously improving and innovating.
BRL SIKB 4000
EARTH has been granted an Excavation Permit since 2010 and has been using its own quality systems for years – to be able to optimally serve our customers. According to the new Heritage Act, it is legally required from July 2017 to be certified for conducting archaeological research and to comply with the Archaeology Assessment Guideline (BRL SIKB 4000 version 4.1). The requirements of the BRL 4000 are included in the existing quality system of EARTH with which EARTH has officially been certified for all protocols 4001, 4002, 4003 en 4004. This means that EARTH is ready for the future and will continue to deliver the same high quality of archaeological research.
The certificate has been issued by certification company SGS Intron (www.sgs.nl). Through various audits in the office and in the field, SGS Intron has determined that EARTH Integrated Archaeology meets the requirements of the assessment guideline.

CO2 performance ladder
EARTH is actively reducing its CO2 emmision. The CO2 performance ladder is a Dutch standard to stimulate companies to be CO2 responsible in their own operations and the execution of their projects. This entails energy reduction, efficient use of materials and increase use of sustainable energy sources. More information can be read on
The CO2 performance ladder is our primary instrument to map our emission assessment, or Carbon footprint, to work towards reduction and to accomplish this actively with other parties working with us.
You can find our most recent CO2 performance ladder certificate here, issued on 22-12-2022 door SGS INTRON Certificatie B.V:
It all starts with understanding the current CO2 emissions. We have developed an emission assessment sheet, which we use to measure our emission CO2-footprint and to provide insights to you. You can also review our portfolio on www.SKAO.nl

Following on from our emission assessments we have defined a number of goals. With these we are actively aiming to reduce our footprint. EARTH wants to realise a reduction of 50% of CO2 emissions in the following years upto 2024. We plan to achieve this by increasing the use of electrical cars and improving the sustainability of our office in Amersfoort. You can find our reduction goals in the: Energy Management Actionplan 2022.

On this page we want to regularly update you on our CO2 performance in order to provide insight in our CO2 footprint and our ambitions and goals on reducing the CO2 emission. We will publish our CO2 footprint performance internally and externally on a yearly basis.
EARTH is part of the industry innitiative “De Duurzame Leverancier” [The Sustainable Supplier]. This is a platform for organisations that invest in sustainability. EARTH has made this choice because this initiative encompasses a broad range of industry in which soil investigation is a important field under which archaeological research can be categorised.
