5.4 Chapter Summary
Key Takeaways
- Pillars of Sustainability: Sustainability is defined by the Brundtland Commission as meeting present needs without compromising future generations. It is built on three pillars: Social Sustainability, Economic Sustainability, and Environmental Sustainability.
- Sustainability in Food Services: Food service operations can contribute to sustainability by conserving energy, reducing waste, composting, recycling, minimizing packaging, using organic products, and purchasing locally.
- Energy Conservation and Management: Food services consume five times more energy per square foot than other commercial buildings and strategies for conservation include upgrading to ENERGY STAR equipment, improving HVAC efficiency, using LED lighting, and implementing smart thermostats and demand hoods.
- Food Waste Reduction Strategies: Food waste prevention methods include accurate forecasting, proper storage, demand purchasing, and menu flexibility.
- Reducing Carbon Footprint through Local Purchasing: Transporting food contributes significantly to greenhouse gas emissions, so buying local food reduces transportation emissions and supports sustainability goals.

Key Terms
Baseline: The initial measurement or starting point used for comparison when evaluating changes or improvements over time in a sustainability program.
Brundtland Commission: A United Nations commission established in 1983 to address global environmental and development issues. It introduced the widely accepted definition of sustainability in its 1987 report Our Common Future.
Carbon Footprint: The total amount of greenhouse gases, particularly carbon dioxide (CO₂), emitted directly or indirectly by an individual, organization, or product over a specific period.
Demand Hoods: A ventilation system used in commercial kitchens that operates only when heat or smoke is detected, reducing unnecessary energy consumption.
Demand Purchasing: A purchasing strategy where only the necessary amount of supplies or food is bought to meet production needs, reducing excess inventory and waste.
Economic Sustainability: The ability of communities and businesses to maintain financial independence and access resources necessary for long-term economic stability and growth.
ENERGY STAR: An internationally recognized certification program that identifies energy-efficient appliances and equipment, helping consumers and businesses reduce energy consumption and environmental impact.
Environmental Sustainability: The practice of using natural resources in a way that maintains ecological balance, ensuring they can replenish themselves over time without causing long-term harm to the environment.
First In / First Out (FIFO): A food storage and inventory management practice where older stock is used before newer stock to prevent waste and ensure freshness.
Forecasting: The process of using past data and trends to predict future demand, such as estimating the amount of food needed for meal preparation in a food service setting.
Greenhouse Gases (GHGs): Gases such as carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O) that trap heat in the Earth’s atmosphere, contributing to climate change.
HVAC (Heating, Ventilation, and Air Conditioning): A system used in buildings to regulate indoor temperature, air quality, and humidity for comfort and efficiency.
LED (Light-Emitting Diode): A highly energy-efficient lighting technology that consumes significantly less power than traditional incandescent bulbs while producing the same or better light output.
SMART Goals: A goal-setting framework that ensures objectives are Specific, Measurable, Attainable, Relevant, and Time-bound to improve effectiveness and success.
Social Sustainability: The aspect of sustainability that ensures all people have access to basic human rights, resources, and opportunities to maintain their well-being and security.
Sustainability: Meeting our own needs without compromising the ability of future generations to meet their own needs.
