The international standard for sustainable procurement, ISO 20400, has been around for five years, giving us internationally accepted best practice on how to purchase goods and services in the most sustainable way possible. We’ve supported many organisations – from sectors as diverse as construction, government, FMCG and manufacturing – in evaluating and building their competence and delivery of sustainable outcomes through procurement.
While we see a push on all areas of sustainability through procurement, climate change and carbon come out as priorities time and time again, no matter what the organisation does.
Why? Well, there are many external drivers – legislative and voluntary – for addressing both your own carbon emissions and those of your supply chain, with a bewildering array of acronyms: SECR, PPN 06/21 and SBT, to name but three of them. And then there’s Net Zero Carbon, which essentially means reducing your emissions and those of your value chain as far as possible and as close to zero as possible.
To put some context on this, depending on where you sit in the value chain, between 70% and 99% or more of your overall carbon emissions and impacts can come from your value chain; your scope 3 emissions. And this leads us to procurement…
Here’s a real-world example that describes this. Working with a major UK University, Action Sustainability calculated that their supply chain (scope 3) emissions are 75% of all their greenhouse gas emissions. In other words, scope 1 and 2 emissions from direct fossil fuel use and electricity consumed on site only account for a quarter of their emissions. The scope 3 emissions comprise business travel, commuting, waste, water, and procurement of goods and services.
And this is the kicker: the last category accounts for two-thirds of their scope 3 total. In other words, buying the products and services they use leads to 50% of all their GHG emissions, with construction, laboratories and IT being the biggest sources.
Use ISO 20400 as your framework and roadmap for understanding where the risks and opportunities for carbon emissions lie in your supply chain. The Standard calls this prioritisation – we call it heatmapping. It all amounts to the same thing: RAG rating where there is high probability of carbon emissions occurring in your supply chain that you can influence. Some tips:
Following these simple steps can get procurement and your supply chain contributing to help you get to where you want to be on your journey to Net Zero Carbon.
Putting this into reality, Action Sustainability recently supported a collaborative group of Local Authorities to do just this. We built a Low Carbon Procurement Toolkit with a risk and opportunity approach to life cycle carbon at its core. The Toolkit contained the heatmap with model ITT questions and responses, supported with an overarching Policy, and Supply Chain Charter to communicate their intentions with the supply chain. This now gives the Authorities a consistent and detailed approach to engaging their suppliers on carbon in the move towards Net Zero Carbon.
