Working in partnership
As a small, not-for-profit organisation, we know that we can’t do everything and can’t do it all at once, but we can do our bit.
In March 2023, we published our first Sustainability Plan. The first year of delivery was a big learning curve, and we focused as much on ‘how we do things’ as on ‘what we do’. Our grass-roots, employee-led programme captured the hearts and minds of our colleagues and proved sustainability is not just a nice thing but a must-have for MOSL. We have now developed the project into a company-wide programme, and this is being implemented at every level of the organisation.
As an organisation working in the water sector, we take our commitment to water efficiency and climate change seriously – it’s important to us that we ‘practice what we preach’ and do what we can to reduce our impact on the environment. We work closely with partners to make a bigger impact.
2024/25 Sustainability Report
Since we launched our first Sustainability Plan in 2023, we’ve built some solid foundations and made good progress.
This year our 2024/25 Sustainability Report includes our 2025/26 commitments as we move to a two-year reporting cycle. Some work packages are evolutions, some are bold new actions - but all of them support us in driving sustainability practices both within MOSL and beyond.
We are proud of the susntainability work we are doing. Recent highlights include reducing our carbon footprint by 28%. We have published new dashboards to help communicate a market consistent approach to calculating water efficiency savings and we continue to champion EDI - check our our EDI Toolkit.

Chris Pond
Board Sustainability Sponsor
"I am thrilled to be the new Board-level sponsor for sustainability. When I joined MOSL, it was clear the organisation was passionate about doing good work – not only in terms of its business plan commitments but in terms of its responsibilities to colleagues, communities and its industry. I look forward to championing this good work as it develops and hopefully bringing others with us on the journey."

Lyvia Nabarro

"MOSL is an organisation that believes in being a responsible business. This means reducing our impact on the planet, working to safeguard our resources and provide a safe, inclusive and diverse working environment. We believe in building communities and leveraging these communities to share experience and knowledge.”
What's next?
We’re incredibly proud of everything we have achieved, but this is just the start. We’re committed to continuing to roll out our employee-led wellbeing programme, improve our carbon reporting, and share our data dashboards and maps to help organisations make more informed water efficiency decisions.
