About Us
Shaped by Experience, Powered by People.
At Arthian, we’re more than consultants, engineers and scientists – we’re collaborators, problem-solvers and advocates, helping clients navigate complexity with clarity, purpose and confidence.
Our team includes planners, environmental scientists, engineers, safety and sustainability consultants united by a shared commitment to delivering client-focused solutions that make a difference.
We combine technical excellence with a client centric approach, working across the full lifecycle of a project – from the beginning stages of feasibility and planning through to design and construction, and site surrender. Our multidisciplinary approach allows us to offer strategic insights and sustainable solutions across energy, industry, infrastructure, and the built environment. What makes us unique is our people. Our clients value our responsiveness, integrity, and the way we consistently go above and beyond to achieve results. At Arthian, every client receives a personal experience backed by technical expertise.
Sustainability
Sustainability is at the core of who we are – and how we work. Running an ethical business means holding ourselves accountable as much as we do our clients, and we take our Environmental, Social and Governance (ESG) responsibilities seriously.
In recent years we have taken measures to track our own emissions and adhere to a Carbon Reduction Plan – but we’re now taking things much further. From 2025/26 onwards, we are directing investment back into our own operations, supporting practical projects that cut emissions at source across our offices and activities.
What sets us apart is that sustainability isn’t just an internal commitment – it’s a capability. Our dedicated sustainability, climate, and carbon consultants work with clients every day to measure impacts, develop decarbonisation strategies, and design resilient solutions. This means the same expertise guiding businesses also drives our own journey towards a lower-carbon future.
At Arthian, we believe progress comes from leading by example – reducing first, operating responsibly, and always looking for innovative ways to create long-term value for people, communities, and the planet.

Corporate Social Responsibility
At Arthian, we believe that engineering and environmental consultancy should leave a lasting positive impact – not only for our clients, but for the communities and environments in which we work.
Our Corporate Social Responsibility (CSR) commitment is rooted in collaboration, integrity, sustainability, and passion. These values guide how we deliver projects, support our people, and contribute to wider society. We are shaped by expertise, powered by people – and it’s through our people that we make the greatest difference.
We take a holistic approach that reflects both our heritage and our future ambitions:
- Environmental Stewardship – Our climate and carbon, sustainability, and environmental teams help clients reduce impacts while we continually work to minimise our own footprint, having already achieved measurable reductions in our operational carbon emissions.
- People and Communities – Every Arthian employee is given the opportunity to donate a full day of time each year to a charity of their choice. We are also supporters of Developing the Young Workforce and advocates for STEM programmes across the UK, inspiring the next generation of engineers and environmental specialists.
- Ethical Business – We hold ourselves to high standards of governance and transparency, ensuring our work is delivered responsibly, safely, and with integrity.
- Positive Legacy – Whether through enabling clean energy, restoring habitats, or improving resilience, we aim to leave behind infrastructure and solutions that make a meaningful difference for future generations.
CSR at Arthian is not a stand-alone programme; it’s how we do business every day.
