Certifying a Carbon Footprint Reduction of 60% for Morrisons’ Eggs

Comprehensive monitoring and assessment helped Morrisons demonstrate a significant reduction in emissions from their 'Better for our Planet' eggs.

About Morrisons

A leading UK supermarket making strides towards net zero

Morrisons is committed to achieving net-zero operational emissions (scope 3) by 2035, 15 years ahead of the UK government’s target.

As British farming’s biggest direct single customer, the company has sought to enable their consumers to make more sustainable choices, this includes BSI Kitemark for carbon neutral products certifcation their 'Better For Our Planet' eggs.

The Challenge

Fulfilling a commitment to Net Zero by 2035

With carbon emissions ingrained in the food production and retail process, Morrisons recognized the need for independent assessment.

Morrisons is actively reducing emissions in its supply chain and supporting farmers in achieving collective net-zero goals.

In 2020, Morrisons began selling carbon-neutral eggs in 50 of its stores as part of a pilot scheme. While the carbon footprint of the eggs was calculated by industry experts using systems verified by the University of Cambridge, Morrisons was looking for an independent and consumer-recognized certification scheme to help provide customers with the assurance that a carbon-neutral status had been reached.

The Solution

Reducing carbon emissions by 60%

A rigorous evaluation process ensured true carbon neutrality and instilled confidence in Morrisons' sustainability credentials.

Working closely with Morrisons and the farmer, we led an independent assessment against the international standards required to achieve the Kitemark:

  1. Carbon Footprint of Products (BS EN ISO 14067:2018)
  2. Demonstrating Carbon Neutrality (PAS 2060:2014)
  3. Carbon Footprint Management Plan (CFMP)

Initially, the egg's carbon footprint stood at 1.56 kg of carbon per 1 kg of egg. Through operational changes, feed adjustments, and staging consumer use scenarios, they successfully reduced this figure by 60%.

Innovative achievements

In order to achieve their goal, Morrisons carried out a number of hugely innovative, carbon reducing operational changes, including:
