Sustainability
Core concepts
Sustainability in coffee spans the whole chain: agronomy (shade management, water use, soil health), processing (water-intensive washed methods vs. lower-water natural methods), transport and roasting (energy efficiency, emissions), and end-of-life (spent grounds, packaging, cups). Candidates should understand that the largest environmental footprint usually sits at the farm and processing stage, not at the café, though café waste and single-use packaging are highly visible and regulated.
Key terms to recognize: shade-grown coffee supports biodiversity; water footprint of washed processing is significant; by-products like cascara and spent grounds can be composted or repurposed; circular economy means designing waste out of the system. Social sustainability includes fair pricing, labor conditions, and traceability.
Traps in questions
- Assuming recycling solves everything. Recycling is the lowest priority after reduce and reuse in the waste hierarchy.
- Confusing certifications (e.g., organic, fair trade, Rainforest Alliance) - each addresses different criteria; none is a complete sustainability guarantee.
- Believing paper cups are automatically better than plastic; many paper cups have plastic linings and are hard to recycle.
- Overlooking that milk and dairy alternatives can dominate a café's carbon footprint compared with the coffee itself.
Worked example
A café wants to cut waste. Using the waste hierarchy, the strongest first move is reduce (default to reusable cups, offer a discount for bring-your-own), then reuse, then recycle. Switching cup material alone ranks lower than eliminating the single-use cup.
