Waste reduction

  • Waste reduction means cutting the amount of materials, resources or products discarded during production or operations, before they become waste needing disposal

Examples of ways to reduce waste

Improving production processes

  • Adjusting machinery settings, cutting offcuts more precisely, or better staff training

  • This reduces the amount of material wasted during manufacturing and means less scrap needs to be disposed of or replaced

Redesigning packaging

  • Using less material, simpler designs or recyclable packaging

  • This cuts the volume of packaging waste created per product sold and often lowers material costs at the same time

Diverting surplus inventory to be reused rather than thrown away

  • Donating, reselling or repurposing unsold or excess inventory

  • This keeps it out of landfill and can generate goodwill or additional revenue instead of needing to be written off

Example

Tesco has cut food waste in its own operations by 45% since 2017 and redistributed more than 25,000 tonnes of surplus food through charities such as FareShare in 2023/24

Advantages and disadvantages of reducing waste

Advantages

  • Lowers disposal costs, as less waste needs to be collected, transported and processed

  • Can generate savings or extra revenue by reselling, donating or repurposing surplus materials

  • Improves brand reputation among customers and other stakeholders who value environmentally responsible businesses

  • Helps meet government waste-reduction targets and avoid fines

Disadvantages

  • Redesigning processes or packaging to cut waste can require significant investment

  • Staff may need retraining to follow new waste-reduction procedures, taking time and management resources

  • Monitoring and reporting waste data accurately can be complex, particularly for large businesses that operate over multiple sites

Resource efficiency

  • Resource efficiency means using the minimum amount of inputs, such as water, energy or raw materials, to produce a given level of output

  • Increasing resource efficiency reduces both environmental impact and the ongoing cost of running operations, since fewer resources need to be bought

Example

Coca-Cola has reduced the water used to make its drinks from 2.7 litres per litre of product to 1.4 litres in some factories, and aims to reach an average of 1.7 litres by 2030

Advantages

  • Reduces operating costs over time by cutting the amount of resources a business needs to buy

  • Reduces exposure to price rises or shortages

  • Supports compliance with environmental regulations on resource use

  • Can improve competitiveness by lowering unit costs relative to less efficient rivals

Disadvantages

  • New equipment or technology needed to improve efficiency can be expensive to install

  • Savings may take years to outweigh the initial investment, creating short-term cash flow pressure

  • It is difficult to improve efficiency across multiple sites

  • A complex, multi-stage supply chain can be difficult to standardise

Reducing emissions

  • Reducing emissions means lowering the amount of harmful gases, such as carbon dioxide, released into the atmosphere by a business's operations

Examples of ways to reduce emissions

Switching to cleaner energy sources

  • Replacing fossil fuels with renewable sources such as wind, solar or hydroelectric power

  • This cuts the carbon dioxide released by a business's operations, alongside long-term energy savings

Improving vehicle and equipment efficiency

  • Upgrading to more efficient engines, electric vehicles or better-maintained machinery

  • This reduces the fuel or energy needed to do the same amount of work, lowering emissions per unit produced

Changing production methods

  • Adopting processes that use less energy or fewer high-emission materials

  • This reduces a business's overall emissions without necessarily reducing output

Example

Ørsted transformed itself from one of Europe's most fossil-fuel-reliant energy companies into a global leader in offshore wind power, cutting its emissions by 98% and closing its last coal-fired power plant in 2024

Advantages

  • Helps a business meet legal emissions limits and avoid fines or legal action

  • Can improve a business's brand image and attract environmentally conscious customers and investors

  • May reduce long-term energy costs once cleaner technology is installed

  • Reduces a business's contribution to climate change, protecting the wider environment it depends on

Disadvantages

  • Switching to lower-emission technology or energy sources often involves high initial costs

  • Existing equipment or vehicles may need replacing before the end of its useful life, meaning extra costs

  • Changing to new methods can cause short-term disruption to production while systems and staff adapt

Reducing carbon footprint

  • A carbon footprint is the total amount of greenhouse gases produced directly and indirectly by a business's activities, including its supply chain, not just its own operations

Examples of ways to reduce carbon footprint

Choosing lower-carbon suppliers

  • Selecting suppliers who use cleaner energy or more efficient processes

  • This lowers the emissions in bought-in materials and components, reducing a business's carbon footprint beyond its own operations

Changing transport methods

  • Switching to lower-emission methods, such as rail or electric vehicles instead of diesel lorries or air freight

  • This cuts the emissions created by moving materials and products through the supply chain

Example

Google has been carbon neutral since 2007 and is aiming to run entirely on carbon-free energy across all its data centres and offices by 2030

Advantages

  • Reduces vulnerability to future carbon taxes or stricter climate regulation

  • Strengthens relationships with customers and investors

  • Can improve efficiency and lower costs, as many carbon-reduction measures also cut energy use

  • Supports long-term business resilience against the physical risks of climate change

Disadvantages

  • Measuring and reducing carbon footprint across the entire supply chain is complex, as it relies on data from external suppliers

  • Suppliers may be unable or unwilling to provide the low-carbon materials or transport needed

  • Achieving carbon reduction targets can take many years, and needs continued investment before results are seen

Sustainable sourcing

  • Sustainable sourcing means buying materials, components or products from suppliers that meet recognised environmental and social standards, rather than from the cheapest available source

Examples of ways to source sustainably

Sourcing from certified suppliers

  • Buying from suppliers with recognised certifications, such as Fairtrade or FSC

  • This gives a business independent assurance that environmental and social standards are being met, without needing to verify this itself

Auditing supply chains

  • Regularly checking suppliers' practices, either directly or through a third party auditor

  • This helps a business confirm that standards are actually being followed and catch problems before they cause reputational damage

Building long-term relationships with responsible producers

  • Working closely with the same trusted suppliers over time

  • This makes it easier to maintain consistent standards and ensure reliable access to sustainably produced materials

Example

IKEA sources 96.5% of the wood used in its products and packaging from FSC-certified or recycled sources, helping protect forests from illegal or unsustainable logging

Advantages

  • Reduces the risk of a business being linked to environmental damage or unethical practices further down its supply chain

  • Can secure more reliable long-term access to raw materials, as sustainably-managed resources are less likely to run out

  • Improves brand reputation and can justify a business using premium pricing for customers who value ethical sourcing

  • Helps meet standards required by increasingly demanding customers and investors

Disadvantages

  • Sustainably sourced materials are often more expensive than less ethical alternatives

  • Verifying that suppliers genuinely meet sustainability standards can be difficult in long or complex supply chains

  • Switching to certified suppliers may reduce the number of suppliers available, risking shortages

Circularity

  • Circularity (or the circular economy) means designing products and processes so that materials are reused, repaired or recycled at the end of their life, rather than thrown away

    • This reduces the need for new raw materials and cuts the amount of waste sent to landfill or incineration

  • Adopting a circular business model requires a shift in mindset, including

    • Involving multiple stakeholders including businesses, governments, consumers and investors

    • Rethinking business processes, product design, supply chains, and waste management practice

Principles of a circular business model

Principle

Explanation

Design for longevity

  • Products are designed to have a longer lifespan, reducing the need for frequent replacement

Resource efficiency

  • Resources are used efficiently throughout the product life cycle, minimising waste and optimising material usage

Recycling and reuse

  • Materials from products that have reached the end of their life cycle are recycled or reused to create new products or components

Product as a service

  • Instead of selling products, businesses provide them as services, such as leasing or renting, encouraging product sharing and extending their lifespan

Biomimicry

  • Nature-inspired design principles are used to create products and processes that mimic natural systems, resulting in greater sustainability

Collaboration and partnerships

  • Businesses collaborate with suppliers, customers and other stakeholders to create closed-loop systems and promote the exchange of materials and knowledge

Example

Adidas has partnered with Parley for the Oceans to make trainers using recycled ocean plastic, turning waste plastic and old fishing nets into a recycled yarn used in its products

Advantages

  • Reduces reliance on new raw materials, lowering costs and environmental impact over time

  • Can create new revenue streams, such as repair services, resale schemes or recycled product lines

  • Improves brand image among customers who increasingly expect businesses to minimise waste

  • Reduces business exposure to volatile raw material prices by reusing existing materials

Disadvantages

  • Redesigning products and processes to be circular usually needs significant investment in new technology

  • Collecting, sorting and reprocessing used materials can be complex to organise and costly

  • Recycled or reused materials may be more expensive, or lower quality, than newly manufactured alternatives

Examiner Tips and Tricks

When answering questions on reducing environmental impact, always link the specific method described (waste reduction, resource efficiency, emissions, carbon footprint, sourcing or circularity) back to the business in the case study, rather than listing methods generically

Case Study

Meridian Sportswear

Meridian Sportswear logo with a bold white letter M encircled by dynamic blue swooshes on a bright blue background

Meridian Sportswear is a sports clothing and footwear retailer, selling trainers, tracksuits and equipment through its own stores and online.

To reduce the amount of used footwear sent to landfill, Meridian launched a take-back scheme, inviting customers to return worn-out trainers to any store in exchange for a discount on their next purchase. Returned trainers are sent to a specialist recycling company, where materials such as rubber soles and fabric uppers are separated and processed into raw materials for new products, including sports flooring and cushion stuffing.

Setting up collection points and training staff to run the scheme took several months and required investment in transport and storage at each store. Some customers were initially unsure how the scheme worked, and uptake was slower than expected in its first year. However, media coverage of the scheme improved Meridian's reputation among environmentally conscious customers, and the business reduced its need to buy some raw materials by reusing recycled rubber in new product lines.
