Efficient refrigeration to cut refrigeration & cold chain emissions

The reduction potential, measured

88 /100

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

Cooling kWh/bottleRefrigerant leaks

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.

Scope & reporting: Combines Scope 1 (refrigerant leaks) and Scope 2 (energy) in a complete inventory.

How to implement the lever

  1. 1Insulate tanks and cold rooms.
  2. 2Right-size and maintain the cooling equipment.
  3. 3Monitor and repair refrigerant leaks.
  4. 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.
