## Green Dining: Sustainability & Savings
* Explores the intersection of environmental responsibility and fiscal efficiency in university settings.

## The Problem: Waste & Cost
* A single campus generates **1,000–1,500 lbs** of food waste daily.
* Total institutional costs range from **$50,000 to $100,000 annually** in lost resources and disposal fees.

## Psychology of Sustainability: The Power of Gratitude
* Reference to Kates and DeSteno's research on the 'Tragedy of the Commons'.
* Study data: Grateful participants took fewer resources (4.1 points) compared to neutral (8.5) or happy (9.2) participants.
* Practice: Micro-moments of acknowledgment before meals disrupt impulsive over-consumption.

## Behavioral Nudges
* **Trayless Dining:** Forces portion control and reduces waste.
* **Default Bias:** Normalizing plant-based meals as the standard choice to lower carbon footprints.

## The Financial Argument: Projected Annual Savings
* **Trayless Dining (Water/Energy):** $4,200
* **Food Waste Avoidance:** $75,000
* **Reusable Container Program:** $130,000

## Future Vision
* Goal: Reaching an 'Immunity Threshold' where sustainable behavior is the social norm.
* Action Plan: Student surveys, 'Trayless Tuesdays', and gratitude prompts in dining halls.
