Our mission
We’re solving todays biggest environmental challenges by expertly managing infrastructure to prevent pollution. When environmental incidents do occur, we swiftly respond across air, land, or aquatic environments.
Our specialist environmental consultancy aids organisations in preventing and remediating pollution whilst shaping their strategic environmental and infrastructure plans. Our environmental engineering constructs, maintains, and transitions assets to achieve operational and ESG targets.
To address increasing environmental challenges, dedicated divisions tailor our expert services for water, energy, and large-scale industrial infrastructure. Together with our customers, we’re transforming infrastructure to create a sustainable economy, a healthier environment, and a better future for humanity.

Our consultancy services span two critical areas:
- Strategic consulting: Defining long-term budgets, optimising assets, and formulating ESG strategies.
- Diagnostic and preventive consulting: Mitigating harm to the environment, proactively minimising risks, and comprehending impact and mitigation strategies where challenges arise.


Environmental engineering
Our environmental engineering services encompass:
- Comprehensive asset and environmental management: Guiding the entire lifecycle, from installation and preventive maintenance through to decommissioning.
- Incident response excellence: Swift pollution remediation and effective environmental impact mitigation.
- Facilitating assets transition and future energy technology integration: Preparing for an environmentally sustainable, Net-Zero future.
A message from our CEO, Henrik Pedersen
Awareness of the profound impact our businesses, economy, and choices have on our environment is growing. It is now imperative that we shift towards a more sustainable approach in how we operate, work, and live.
Our vision is a world where we:
- Proactively prevent and mitigate pollution events across all environments and contexts, placing a strong emphasis on tackling complex pollution challenges such as forever chemicals and PFAS, which are increasingly pervasive.
- Effectively manage water resources, especially in regions with ageing water infrastructure. We aim to enhance wastewater infrastructure to prevent sewer pollution events and develop sustainable freshwater supply systems to meet rising demand.
- Enhance biodiversity to not only bolster agricultural yields but also foster a sustainable world with a richer ecological landscape.
- Facilitate the transition to new, clean energy sources, supporting society's journey towards Net-Zero and thereby curbing pollution.
- Adapt and mitigate the impact of climate change, ensuring our ability to thrive in a changing climate.
The United Nations initiated its ESG program to unify the global community in making this crucial transformation. Adler and Allan stands at the forefront of this, actively creating practical, sustainable solutions. We minimise environmental impact and enhance the resilience of business to respond to and manage climate change.
Our mission encompasses delivering comprehensive environmental consultancy and engineering services that not only better the environment but also cater to the diverse operational needs of our customers.
The 21st century will present numerous and sustained environmental challenges, but embrace them proactively for our clients, putting ESG principles into practical action every single day.
