A summary of the key takeaways from a recent webinar on reducing scope 3 waste-related emissions.

Shoosmiths is delighted to be sponsoring United Nation Global Compact Network (UNGC) UK’s series of webinars on ‘Reducing Scope 3 Emissions’.

The event featured guest speakers: Emma Watson, Net-Zero Senior Manager, CDP and Science Based Targets initiative (SBTi); Kim McCann, Global Head of Sustainability - Consumer & Manufacturing, PA Consulting; and Dr Warren Bowden, Head of Sustainability & Innovation, Scottish Leather Group.

• Categories 5 and 12 of the Greenhouse Gas Protocol’s Corporate Value Chain Accounting and Reporting Standard address Scope 3 emissions associated with a company’s upstream and downstream waste in the reporting year.
• As per the Greenhouse Gas Protocol’s Technical Guidance, emissions arising from waste generated in operations (Category 5) can be calculated by:
  • Supplier-specific method, which involves collecting waste-specific Scope 1 and Scope 2 emissions data directly from waste treatment companies (e.g., for incineration, recovery for recycling).
  • Waste-type-specific method, which involves using emission factors for specific waste types and waste treatment methods.
  • Average-data method, which involves estimating emissions based on total waste going to each disposal method (e.g., landfill) and average emission factors for each disposal method.
• These methods can also be used to calculate emissions from end-of-life treatment of sold products (Category 12). However, companies should instead collect data on total mass of sold products (and packaging) from the point of sale through to consumer disposal.
• For many sectors, waste-related emissions may be relatively immaterial in comparison to other Scope 3 emissions categories. However, there are significant opportunities to explore circularity and instead reduce emissions associated with purchased goods and services. For example, businesses can:
  • Use by-products for another use. For example, using a beer by-product to produce baked goods.
  • Find new uses for used products; for example, Ecobooth transforms hard-to-recycle plastics into equipment for live event activities.
  • Reduce waste; for example, Dole Asia Holdings has implemented new processes to eliminate waste and better inform decision-making.
• Major partnerships are bringing circular business models to life, for example:
  • Retailers are acquiring facilities and partnering with other companies across the packaging waste value chain. For instance, Morrisons will become the first supermarket to own its recycling operations, having bought a stake in a recycling plant.
  • Key technologies are scaling fast; UK chemical recycling reprocessing capacity is expected to grow by 45% each year from 2020 to 2030.
  • Some energy companies are integrating waste management capabilities and treatment technologies to capture the increasing demand.
• Waste can be converted into heat to reduce reliance on fossil fuels (and associated emissions) and waste-related emissions, as exemplified by Scottish Leather Group.
• It is key to present a business’ waste impact in a clear and transparent way. Life cycle analysis (LCA), which incorporates supply chain emissions, can be very useful for this.
• Regulations around waste-related emissions are imperfect. The future changes to EPR regulations adding to existing regulations) will likely generate high compliance costs, so businesses should act now to minimise these.
