We always behave in ways that build lasting relationships and show we care and value our customers, colleagues and partners.

We use our expertise to help customers be the best at what they do. Our customers often know what they want, however knowing what they need means really understanding everything about them. We always look for new opportunities to learn and develop, and openly celebrate when things go well. Things may not always go as planned, but working together, we share our knowledge to improve things for the better.

Sustainability

Engineering a responsible future.

Creating lasting value

For today’s global businesses sustainability represents far more than environmental responsibility – it is about creating lasting value while ensuring organisations can thrive well into the future. It encompasses not only the protection of natural resources and reduction of environmental impacts, but also the nurturing of strong communities, ethical supply chains, and resilient business models. Our approach balances profit with purpose, ensuring alignment across diverse markets and cultures.  Success demands looking beyond quarterly results to consider how decisions today will impact stakeholders tomorrow – from employees and customers to local communities and future generations.

Strategic alignment with global standards

At the heart of our business strategy, we have committed to establishing meaningful goals and rigorously monitoring progress in order to make a tangible difference. We are embedding sustainability into the way we operate, influence, and engage; working collaboratively towards a safer, more sustainable world.

In establishing our forward-looking objectives, we have strategically aligned our aspirations with the United Nations’ Sustainable Development Goals (SDGs). We have carefully selected 7 of the UN SDGs that most closely correspond with our transformation priorities and areas where we can deliver meaningful impact through our engineering solutions and operational practices:

  • Goal 3: Good Health and Well-being
  • Goal 5: Gender Equality
  • Goal 7: Affordable and Clean Energy
  • Goal 9: Industry, Innovation, and Infrastructure
  • Goal 11: Sustainable Cities and Communities
  • Goal 12: Responsible Consumption and Production
  • Goal 13: Climate Action

 

Our commitment to sustainability is already showing positive results:

2023: James Walker received the 2023 BPF Energy Award for energy efficiency improvement from the British Plastics Federation. With over 500 member companies, the BPF represents over 80% of the UK plastics industry by turnover. In support of all energy initiatives undertaken by the plastics industry, BPF Energy makes an award each year to acknowledge energy efficiency improvement within the Plastics Sector Climate Change Agreement.

2024: edilon)(sedra GmbH was awarded the “Green Mandate” and “Innovator of the Year” by the law firm ETL-Gruppe. The campaign focuses on SMEs whose products and services are particularly sustainable and climate-neutral, or who develop green innovations and technologies and are committed to decarbonisation and environmental protection.

A snapshot of key performance indicators at the close of 2024:

  • 88% of relevant Group sites certified to ISO 14001
  • CDP rating for climate C
  • CDP rating for Water B-
  • 5% reduction in electricity purchased in 2024 v 2023

A culture of sustainability

Sustainability goes beyond the tracking of key performance indicators. It requires a fundamental shift in culture across all our businesses. Every decision and action taken by every employee must support our mission to meet the needs of today, without compromising the ability of future generations to meet their own. We are committed to creating and driving a business model that not only withstands the test of time but actively contributes to the development of a healthier, more  equitable world.
