Ramboll’s commitment to scientific integrity and transparency

Our multidisciplinary staff includes environmental scientists and engineers, public health and safety specialists, economists, statisticians, and regulatory experts, who provide a wide range of consulting and engineering services. Much of our work for both public and private sector clients involves estimating and effectively communicating the potential human health and environmental risks associated with chemical contamination, identifying options for safe, cost-effective risk reduction, and, where appropriate, implementing remedial actions. We also assist private sector clients in understanding and managing their potential environmental liabilities, maintaining compliance with regulatory requirements, and achieving their sustainability goals.

By working with a variety of clients in both public and private sectors, Ramboll is able to better understand the broad spectrum of technical perspectives that may exist on key issues. We provide our clients with clearly communicated and transparent findings and opinions based on objective analysis of the best science.

Ramboll advocates for relying on the best science in regulatory decision-making. Our work can help regulatory agencies make informed decisions based on their own analysis and balancing of relevant criteria.

In addition to our work for public and private sector clients, Ramboll staff are often asked to participate on expert panels convened by scientific organisations and regulatory agencies. Examples include:

• US Environmental Protection Agency (EPA)
• USEPA Science Advisory Committee on Chemicals (SACC)
• The National Research Council (NRC) Board on Environmental Studies and Toxicology
• The US Army Environmental Center
• The American Society of Testing Materials (ASTM)
• The National Institute of Environmental Health Sciences (NIEHS) Superfund Basic Research Program
• American Board of Toxicology (ABT)
• The United States Congress
• UK REACH Independent Scientific Expert Pool (RISEP)
• UK Committee on Toxicity of Chemicals in Food, Consumer Products and the Environment (COT)
• UK Committee on Carcinogenicity of Chemicals in Food, Consumer Products and the Environment (COC)

Ramboll retains its independence and strives to avoid perceived conflicts of interest for all clients and on all projects by making certain that our conclusions and opinions are based on objective and transparent evaluation of scientific evidence from reliable sources.

Ramboll also follows an internal new project review process for all proposed client engagements, to ensure that we avoid actual or perceived conflicts of interest and comply with any existing contract restrictions. Where appropriate or required, we will establish ethical walls to protect against disclosure of client information or communications that may be considered confidential in nature.        

Public procurement processes are designed to uphold transparency, fairness and integrity. Ramboll diligently follows these procedures to ensure that any potential conflicts of interest are identified and cleared before engaging in consulting or engineering work for public agencies and regulatory bodies.

Transparency is a cornerstone of Ramboll's work. We apply rigorous methodologies to ensure our analyses are clear and reliable, citing the sources of data, models and approaches we use to develop our conclusions and recommendations. Our experts regularly publish their work to allow for review by the scientific community and contribute to progress in resolving important environmental and human health issues. Examples include:
