How are environmental sustainability, environmental science, and economics related?

I'm studying environmental policy and often see "sustainability" presented as a vague ideal. In practice, how do the hard data from environmental science (e.g., a pollution loading limit) get translated through economic models (like cost-benefit analysis) into a viable policy that balances the three pillars? I'm looking for a concrete example of this interdisciplinary negotiation.

In my work with policy committees, the interaction is often a tense but necessary dialogue. Environmental science provides the non-negotiable constraints the "what" (e.g., a river can assimilate only X kg of pollutant). Economics then analyzes the "how" by modeling the least-cost pathways for society to meet that target, using tools like pollution trading or Pigouvian taxes. Sustainability is the negotiated outcome of this process. For example, setting a carbon price: climate science defines the safe cumulative budget, economics models the price needed to stay within it, and the final policy reflects a sustainability judgment on equitable burden-sharing and transitional support. The friction arises when economic efficiency conflicts with scientific precaution.
