Today’s consumers are increasingly choosing stores and brands that align with their environmental values. They are not just asking for sustainability; they’re demanding it, expecting retailers to disclose and actively reduce emissions across their entire value chain.
Meeting these demands is not just a tall order—it’s a complex challenge that requires strategic planning and innovative solutions. With vast refrigerated aisles and intricate supply chains, the journey to sustainability isn’t a straightforward path for retailers.
Navigating these challenges will require adopting new technologies, instilling a sustainability culture within the organisation, engaging with stakeholders, and progressively shifting towards cleaner practices.
Energy usage in the food chain
Energy usage in food retail spans from energy-intensive refrigeration units to keep perishables fresh, efficient lighting solutions to illuminate expansive store layouts and the complex logistics to get products on the shelves. All these operations are an integral part of the food chain and typically result in a considerable carbon footprint.
Imagine each stage of the supply chain, from production to delivery, with its own emission challenges.
Coupled with this are pressures from multi-regional and dispersed supply chains; each has to be assessed independently for energy efficiency, and each region has its own regulations and energy sources, so this is a challenging task.
Advanced technology and collaboration across the entire value chain are needed to shift towards more sustainable practices, but it takes work, given the varying degrees of sustainability practices currently in place among suppliers.
Transportation of goods often relies on fossil fuels, a significant emission source. Optimising logistics through ‘smarter’ routing systems and investing in electric or hybrid delivery fleets can mitigate some of these impacts.
Refrigeration is essential for keeping perishable goods fresh but also a pain point when it comes to sustainability as they are notorious for their high energy consumption. A typical supermarket in the UK uses around 700–1,000 kWh of energy per square metre. Science Direct breaks down energy use: Refrigeration: 30–50%
Lighting: 15–25% Space conditioning: 20%.

The green consumer
Interestingly, despite these challenges, there’s an optimistic wave. Many consumers are ready to dig deeper into their pockets for sustainable products. This trend presents opportunities for retailers to invest in energy-efficient technologies and renewable energy sources, eventually meeting consumer expectations and environmental needs.
The Harvard Business Review believe there has never been a better time to launch a sustainable offering with consumers—particularly Millennials—saying they want brands that embrace purpose and sustainability, and 65% saying they want to buy purpose-driven brands that advocate sustainability.
Committing to innovation
By investing in energy-saving technologies and leveraging partnerships with technology companies, retailers can pave the way to meet their net-zero expectations, reduce their environmental impact and align with consumer values.
The journey to net-zero operations may be fraught with obstacles, but it is also an opportunity. For every hurdle in reducing energy consumption and transforming supply chains, there lies the potential to forge stronger connections with conscientious consumers and set industry benchmarks.
Embracing these challenges is not just about survival; it’s about leading the way towards a greener future. By committing to innovation, leading by example, ensuring compliance, and transforming towards sustainability, your company can inspire new ways of doing business and position itself as a leader in the sustainable retail landscape.

Refrigeration is a cornerstone of modern life. It’s vital for food preservation and medical applications and provides comfort in our homes and workplaces.
Yet, this essential technology has a hidden cost – it plays a significant role in global warming.
This is because refrigeration systems rely on chemicals known as refrigerants, many of which have a high Global Warming Potential (GWP).
The energy used in refrigeration often comes from fossil fuels, contributing to CO2 emissions and further exacerbating climate change.
In this article, we’ll explore the impact of refrigeration on global warming, the role of cooling technology, its relationship with food manufacturing, and its broader implications for our climate.
We will uncover the complex relationship between refrigeration and global warming and explore potential solutions for a more sustainable future.
The Essential Role of Refrigeration
Refrigeration is crucial for storage and transportation in industries like food manufacturing. It’s also indispensable in healthcare, especially for vaccine storage. Without refrigeration, many aspects of modern life would be impossible.
Refrigerants and Their Environmental Impact
Refrigeration relies heavily on chemicals known as refrigerants. These substances absorb and release heat, enabling cooling. However, many refrigerants have a high Global Warming Potential (GWP).
Hydrofluorocarbons (HFCs) are common refrigerants. They are potent greenhouse gases, contributing significantly to global warming. Leakage of these substances during maintenance or disposal is a primary environmental concern.
Here are some key facts about HFCs:
They can trap more heat in the atmosphere than carbon dioxide.
HFC emissions are increasing by about 10% per year.
They are expected to account for nearly 20% of all greenhouse gas emissions by 2050.
The environmental impact of refrigerants is a complex issue. It involves many stakeholders, from manufacturers to consumers, and requires international cooperation.
The Kigali Amendment and Global Efforts
The Kigali Amendment to the Montreal Protocol is a global effort to reduce HFC use. It aims to cut the production and consumption of these gases by more than 80% over the next 30 years. This could avoid up to 0.4°C of global warming by the end of the century.
However, implementing the Kigali Amendment requires significant changes in the refrigeration industry. It also needs the support of consumers and policymakers. The transition to more sustainable refrigerants is challenging but crucial for our planet’s future. (Regulations in the UK are commonly referred to The F Gas Register).
International cooperation is necessary to address this global challenge. It’s not just about reducing emissions but also about promoting sustainable development and protecting the most vulnerable from the impacts of climate change.
Innovations in Cooling Technology
Innovations in cooling technology are paving the way for more sustainable refrigeration. For instance, magnetic cooling is a promising technology that uses magnetic fields and magnetocaloric materials to achieve refrigeration. This technology is still in its early stages, but it could significantly reduce the environmental impact of cooling.
Another innovation is using natural refrigerants like ammonia, CO2, and hydrocarbons. These substances have a much lower Global Warming Potential (GWP) than traditional refrigerants. The challenge lies in making these technologies affordable and accessible to all.
Digital technologies are also improving refrigeration efficiency. Smart systems can monitor and optimise energy use, reducing costs and emissions. The future of refrigeration lies in harnessing these innovations to create effective and environmentally friendly systems.
Refrigeration in Food Manufacture and the Cold Chain
The food and beverage industry is the largest manufacturing sector in the UK, and food cold chains are energy-intensive and use high-GWP refrigerants.
Refrigeration plays a crucial role in food manufacturing and the cold chain. It allows for the storage and transport of perishable goods, reducing food waste and ensuring food safety. However, the energy-intensive nature of these processes contributes to global warming.
The food cold chain alone is responsible for a third of hydrofluorocarbon (HFC) emissions, or 1% of global greenhouse gas (GHG) emissions and food refrigeration is estimated to be responsible for 2–4% of the UK’s total GHG emissions Source: ScienceDirect.com
Innovations in refrigeration technology can help make the cold chain more sustainable. For instance, energy-efficient refrigeration systems and natural refrigerants can reduce the cold chain’s environmental impact.
Energy Consumption and Refrigeration
Refrigeration systems account for a substantial percentage of global electricity consumption. This energy often comes from fossil fuels, contributing to CO2 emissions and global warming.
Scope 1 and 2 GHG emissions related to food refrigeration in the UK were estimated to be 12.9 MtCO2e per annum over the period 2019, which represents 3.2% of the total UK annual territorial greenhouse gas emissions. Scope 2 emissions accounted for 50% of the emissions. International Journal of Refrigeration June 2023
Transitioning to renewable energy sources can mitigate refrigeration’s impact on global warming. Solar-powered refrigeration, for instance, offers a promising avenue for sustainable cooling technology.
Sustainable Refrigeration Practices
Sustainable practices in refrigeration are gaining traction. These include using natural refrigerants like ammonia, CO2, and hydrocarbons. These substances have a lower Global Warming Potential (GWP) than traditional refrigerants.
Proper disposal and recycling of refrigeration equipment are also crucial. This can prevent the leakage of harmful refrigerants into the atmosphere. Retrofitting existing systems with more sustainable options can be a cost-effective solution.
Innovations such as magnetic cooling offer the potential for greener refrigeration. This technology uses magnetic fields and magnetocaloric materials to achieve cooling, eliminating the need for refrigerants.
The Role of Policy and Consumer Choice
Policies and regulations play a significant role in promoting sustainable refrigeration. For instance, the Kigali Amendment to the Montreal Protocol aims to reduce the use of high-GWP refrigerants. Government subsidies and financial incentives can also encourage the adoption of energy-efficient refrigeration systems.
On the other hand, consumer choices can influence the market towards more eco-friendly options. Awareness and education are vital to changing consumer behaviour. Consumers can reduce their carbon footprint by choosing appliances with better energy ratings.
International cooperation is necessary to address the global challenge of refrigeration-related emissions. Collaboration between manufacturers, consumers, and governments is essential for progress.

Climate change is an existential crisis with far-reaching consequences in various sectors, including the food industry. This industry is integral to human survival but is also a significant contributor to environmental degradation. With a rapidly expanding global population, the pressure to increase food production intensifies, threatening to exacerbate climate-related issues. This article delves into how climate change is reshaping the food industry and underscores the importance of transitioning to sustainable food production.
“Climate change poses an “existential threat” to life on Earth” Phys.org
The ramifications of climate change on the food industry are profound and multifaceted. Fluctuations in climate patterns lead to unpredictable growing seasons, which challenge traditional agricultural calendars and practices. These changes reduce crop yields and lead to the proliferation of pests and diseases, further endangering food security.
Climate change also exacerbates resource scarcity, making water an increasingly precious commodity. As droughts become more prevalent, competition for water resources intensifies, affecting the quantity and quality of food produced. This situation is particularly dire for regions already water-stressed, where farmers must decide which crops to prioritise and how to sustain their herds.
The adverse effects of climate change do not affect all farmers equally. Small-scale and subsistence farmers are especially vulnerable to the whims of the climate. Many of these farmers lack the resources or insurance to recover from crop losses or damage to their property caused by extreme weather events. The resulting economic instability can increase poverty and hunger, further exacerbating social and economic disparities.
Moreover, as climate change disrupts traditional farming practices, there is an urgent need to support farmers in adopting more resilient agricultural methods. Support can include access to education, resources, and technology to help them adapt to the changing environment.
The industrialised food system and its reliance on synthetic fertilisers, pesticides, and fossil fuels are unsustainable and a significant contributor to climate change. Modern agriculture, from farm machinery to food processing and distribution, is energy-intensive and produces substantial greenhouse gas emissions. To mitigate the industry’s impact on the planet, we must completely rethink how we produce and consume food.
The globalisation of the food industry has led to a system where the average meal travels thousands of miles from farm to plate, contributing to a significant carbon footprint. By prioritising locally grown food, we can reduce emissions associated with transportation and provide consumers with fresher, more nutritious options.
Local food systems are inherently more agile and can quickly adapt to changing local conditions, which is paramount in the face of climate instability. These systems also encourage the preservation of local varieties and farming techniques, which can improve the local environment. We can ensure a more personalised and secure food supply chain by fostering local food economies.
Challenges Facing UK Food Retailers
In 2008, the United Kingdom passed a pivotal legislation called the Climate Change Act. This ground-breaking act mandated that the UK reduce greenhouse gas emissions by at least 80% by 2050 compared to 1990. The implications of this act are far-reaching, particularly for industries like food retail that traditionally have a significant carbon footprint.
The term “carbon footprint” refers to the total greenhouse gas emissions caused by an individual, event, organisation, service, or product, expressed as carbon dioxide equivalent.
The Climate Change Act has catalysed change within the UK food retail sector, spurring a shift towards sustainability that benefits the environment.
To meet the stringent requirements, UK retailers have had to re-evaluate and take action to reduce emissions from their operations, from energy and refrigerants in their supermarkets to fuel used in transportation (Scope 1 and 2 emissions); these are significant but controllable sources of greenhouse gas emissions from the food system.
As the deadlines set by the act approach, UK food retailers need to continue to innovate and integrate sustainable practices into every aspect of their operations. This means reducing emissions arising from their entire value chain (Scope 3 emissions), the upstream supply chain, and downstream activities, such as the use and disposal phases, beyond the direct and energy emissions covered within Scopes 1 and 2. Scope 3 emissions are usually retailers’ most significant source of greenhouse gas emissions.
Energy consumption in food manufacturing significantly impacts water usage and pollution. Water is essential for various processes in the industry, including cleaning, cooking, and ingredient preparation. However, excessive water uses, and inefficient water management practices can lead to water scarcity and pollution.
Food manufacturing often requires large amounts of water, particularly for cleaning and sanitation. Inadequate water conservation practices can result in excessive water consumption and strain local water resources. Moreover, the improper disposal of wastewater can lead to water pollution, contaminating rivers, lakes, and groundwater sources.
Food manufacturers can implement water-saving measures to address these issues, such as recycling and reusing water, optimising cleaning processes, and investing in water-efficient technologies. Proper wastewater treatment and disposal systems can also help minimise water pollution and protect the environment.
The WWF Basket tracks a range of climate data submitted by food retailers, including Scope 1, 2 and 3 emissions.
In 2022, Co-Op, M&S, Sainsbury’s, Tesco and Waitrose signed a new commitment to drive action to tackle scope 3 emissions through their supply chains. Find out more about WWF’s Retailers Commitment for Nature – Climate Action here.
Greener Practices for Food Retailers
There are a number of green initiatives that can be adopted by retailers to lessen their carbon footprint. These include:

Furthermore, food manufacturers can explore renewable energy sources, such as solar and wind power, to meet their energy needs.
Investing in renewable energy infrastructure reduces greenhouse gas emissions, helps diversify the energy mix, and enhances energy security.
Additionally, implementing energy management systems and conducting regular energy audits can help identify areas for improvement and optimise energy usage.
By adopting sustainable energy-consumption practices, food manufacturers can significantly reduce their environmental footprint, contribute to a more sustainable future, and help the UK achieve its 2050 net-zero targets.
Harvey & Brockless, renowned producers and distributors of speciality foods, has taken steps towards a more sustainable future and adopted new energy-saving technology, Coolnomix, to help reduce carbon emissions and costs.
Food Chain Technology Innovations
Technology facilitates the development of alternative food sources, such as lab-grown meat and vertical farming, which could dramatically reduce the ecological footprint of food production. These innovations have the potential to provide sustainable protein sources and fresh produce even in urban environments, thereby reducing the need for extensive land use and long-distance transportation.
Technology also empowers consumers to make informed decisions about their food. Through apps and online platforms, individuals can trace the origin of their food, learn about the farming practices used, and understand the environmental impact of their dietary choices. By providing transparency and information, technology bridges the gap between consumers and producers, fostering accountability and encouraging more sustainable consumption patterns.
Social media and digital marketing have given rise to a new wave of consumer activism, where individuals can advocate for sustainable food practices and influence industry trends. As consumers become more vocal and connected, their collective choices can drive significant change in the food industry, pushing it towards more environmentally friendly and ethical practices.
Conclusion
Since the Climate Change Act set out the target of reducing greenhouse gas emissions by 80% by 2050, the cost of electricity has risen from 5.37 pence per kW in 1990 to 10.72 pence in 2020, placing additional pressure on food retailers.
Climate change poses a significant threat to our food system. Still, technological advancements, new tools, and insights are now available to help retailers achieve Scope 3, reduce energy costs, and forge a sustainable food system for all.

The Role of Energy Consumption in Food Manufacturing
“The current energy consumption in agri-food systems is unsustainable in the long term. The food industry is currently consuming 30% of the world’s available energy, with more than 70% occurring beyond the farm gate, and produces over 20% of the world’s greenhouse gas emissions (around 31% if land-use change is included).” Source Food and Agriculture of the United Nations.
The food processing industry is reliant on energy for heating, cooling, and electricity as our food moves through the supply chain, consuming around 30% of the world’s available energy.
Food production requires a significant amount of energy primarily sourced from fossil fuels, which significantly contributes to Greenhouse gas emissions. In the UK, the food processing industry is the largest single manufacturing sector and the fourth largest industrial energy user.
Greenhouse Gas Emissions and Climate Change
The 2008 Climate Act committed the UK to reducing its greenhouse gas emissions by 80% by 2050 compared to 1990 levels. In June 2019, this was strengthened, committing the UK to bring all greenhouse gas emissions to net zero by 2050.
Energy consumption in food manufacturing significantly contributes to greenhouse gas emissions and climate change. Burning fossil fuels releases carbon dioxide (CO2) and other greenhouse gases into the atmosphere. These gases trap heat, leading to global warming and climate change.
There are things that food manufacturers can do to mitigate the impact of greenhouse gas emissions, such as adopting energy-efficient technologies, investing in renewable energy sources, and implementing carbon reduction strategies. These actions will help to reduce the industry’s carbon footprint.
To combat environmental pollution and create a more sustainable food sector, we need to explore how energy usage during the food manufacturing process can be reduced.
Water Usage and Pollution
Energy consumption in food manufacturing significantly impacts water usage and pollution. Water is essential for various processes in the industry, including cleaning, cooking, and ingredient preparation. However, excessive water uses, and inefficient water management practices can lead to water scarcity and pollution.
Food manufacturing often requires large amounts of water, particularly for cleaning and sanitation. Inadequate water conservation practices can result in excessive water consumption and strain local water resources. Moreover, the improper disposal of wastewater can lead to water pollution, contaminating rivers, lakes, and groundwater sources.
Food manufacturers can implement water-saving measures to address these issues, such as recycling and reusing water, optimising cleaning processes, and investing in water-efficient technologies. Proper wastewater treatment and disposal systems can also help minimise water pollution and protect the environment.
Waste Generation and Management
Energy consumption in food manufacturing is also closely linked to waste generation and management. The production and processing of food often result in the generation of various types of waste, including organic waste, packaging materials, and by-products.
Improper waste management practices can have adverse environmental impacts. Organic waste, if not correctly handled, can release methane, a potent greenhouse gas, during decomposition. Packaging materials like plastics contribute to pollution and threaten ecosystems and wildlife. By-products, such as food scraps and manufacturing residues, can also lead to pollution if not managed effectively.
Food manufacturers can adopt waste reduction strategies to address these challenges, such as implementing recycling programs, reducing packaging waste, and finding alternative uses for by-products. Implementing efficient waste management systems, including composting and anaerobic digestion, can help minimise the environmental impact of waste generated in the food manufacturing industry.
Refrigeration
The high energy demand in food manufacturing is largely due to the need for food preservation, packaging, and transportation.
These processes often involve refrigeration, which requires a substantial amount of energy. This reliance on energy-intensive processes in food manufacturing contributes significantly to the industry’s overall environmental impact.
Refrigeration plays a vital role in ensuring food safety in the food industry. By keeping food at low temperatures, refrigeration helps to prevent the growth of harmful bacteria and other microorganisms that can cause foodborne illnesses It slows down the spoilage rate, preserving food products’ quality, freshness, and shelf life.
Refrigeration is also essential for the efficient distribution of food products, allowing the safe transportation and storage of perishable goods over long distances without compromising freshness and quality.
Efficient distribution facilitated by refrigeration also helps to reduce food waste and minimise the risk of product recalls due to spoilage or contamination. It allows for a smooth and reliable supply chain, ensuring consumers can access various fresh, high-quality food products.
But refrigeration at a large scale does come at a financial cost to food manufacturers and our environment.
Sustainable Practices in Energy Consumption
Food producers can minimise their energy wastage during production and the manufacturing process by investing in energy-efficient technologies and equipment, including energy-efficient lighting, motors, and heating and cooling systems.
Furthermore, food manufacturers can explore renewable energy sources, such as solar and wind power, to meet their energy needs.
Investing in renewable energy infrastructure reduces greenhouse gas emissions, helps diversify the energy mix, and enhances energy security.
Additionally, implementing energy management systems and conducting regular energy audits can help identify areas for improvement and optimise energy usage.
By adopting sustainable energy-consumption practices, food manufacturers can significantly reduce their environmental footprint, contribute to a more sustainable future, and help the UK achieve its 2050 net-zero targets.
Harvey & Brockless, renowned producers and distributors of speciality foods, has taken steps towards a more sustainable future and adopted new energy-saving technology, Coolnomix, to help reduce carbon emissions and costs.
Developed by Emissis, Coolnomix is a ground-breaking energy-saving technology that can reduce kWh consumption by up to 40%, making it ideal for food producers that rely on AC and refrigeration equipment as part of their manufacturing process.

Recently, our world has witnessed a concerning rise in temperatures, sparking worries about the intersection of global warming and the increasing demand for air conditioning.
In this article, we examine the effect of air conditioning on climate change and explore how measuring energy useage and adopting technical innovations can help keep us cool without damaging the planet.
“The warmer it gets, the more we use air conditioning. The more we use air conditioning, the warmer it gets. Is there any way out of this trap?” The Guardian
The effects of Air Conditioning on climate change
Air conditioning units have mostly stayed the same since their invention in 1931. Their power consumption exceeds that of most appliances, significantly damaging our power grid, particularly in the summer months.
As world temperatures rise, there is an increasing demand for air conditioning, but cooling significantly contributes to global warming. Much of the existing cooling equipment uses hydrofluorocarbon refrigerants, which are potent greenhouse gases and use a lot of energy, making them a double burden on climate change.
So, while air conditioning helps to make the inside cooler, it also makes the outside warmer through increased emissions, heating up the planet.
“Growing demand for air conditioners is one of the most critical blind spots in today’s energy debate.” IEA.
Demand for air conditioning units surge
The International Energy Agency (IEA) predicts a substantial increase in the number of global air conditioning units, potentially reaching 5.6 billion (two-thirds of the world’s households having air conditioning) by 2050. This surge in cooling demand comes with environmental consequences, with predictions suggesting that space cooling could contribute up to 13% of global greenhouse gas emissions by 2050, producing 2 billion tonnes of CO2 a year.
Despite these challenges, the IEA offers hope, outlining strategies to enhance cooling efficiency, adopt eco-friendly refrigerants, and integrate renewable energy sources.
As temperatures soar and the anticipation of a surge in global air conditioning units looms, the IEA encourages us to investigate new innovative technology that will help us strike a delicate balance between comfort and environmental responsibility.
Measures to reduce your energy usage
An energy audit will help you understand your current energy usage. It will also identify any energy-saving opportunities such as optimising your buildings and checking your air conditioning controls for efficiency, reducing energy wastage.
Adopting new technologies like our innovative solution, Coolnomix, can also help. It has been specially designed to mitigate the environmental impact of air conditioning without compromising performance and can reduce your energy consumption by up to 40%.
