English Social Sciences Economics

I don't understand this concept in contexts like this, for example:

We agree that securing value in the broadest sense, including to the economy, society and the environment, will be absolutely key to Ofwat’s delivery, with stakeholders, of sustainable development.
We support the list of priorities outlined in chapter 5 – water efficiency fits directly into the first four (Securing value in the broadest sense, Promoting long-term planning, Climate change and the Water Framework Directive).

I would be very grateful if someone could provide an explanation, what exactly they mean by value and how do they secure it.
