Efficient refrigeration to cut refrigeration & cold chain emissions
The reduction potential, measured
Time horizon: 1–2 seasons
How it cuts it
It directly tackles the refrigeration source — consumption and leaks — often the cellar’s biggest efficiency opportunity.
What to measure for this pairing
Why this source matters
Refrigeration is an often-underestimated source: cooling ferments, cold-stabilising and storing wine consume a lot of energy, especially in warm climates. Beyond consumption, refrigerant leaks have a very high warming potential.
Improving insulation, the efficiency of cooling equipment and refrigerant management — and powering the cold with renewable energy — reduces this source significantly.
Source indicators
Scope & reporting: Combines Scope 1 (refrigerant leaks) and Scope 2 (energy) in a complete inventory.
How to implement the lever
- 1Insulate tanks and cold rooms.
- 2Right-size and maintain the cooling equipment.
- 3Monitor and repair refrigerant leaks.
- 4Log consumption and leaks for the footprint.
Frequently asked
Do refrigerant leaks matter much?
Yes — many refrigerants have a warming potential hundreds to thousands of times that of CO₂, so small leaks weigh heavily.
How to reduce the cooling load?
Insulation, managing cellar ambient temperature, night-cooling recovery and good maintenance reduce the energy needed.

How GrapeFlow helps
The footprint per bottle and per season, always up to date — the basis of any low-carbon report.
Energy & fuels (invoices by OCR)
Electricity, diesel and other fuels captured from invoices, with consumption per kWh, per litre and per bottle.
Carbon footprint per bottle & season
GrapeFlow gathers energy, fuel, packaging and inputs and computes the footprint per bottle and per season — the basis of any report or low-carbon label.
Vineyard operations & inputs applied
Machine passes, diesel and inputs (nitrogen, treatments) logged by plot — the vineyard’s Scope 1 and 3 emissions.
