Supply Chain Sustainability Management

We collect the supplier carbon data your buyer in the EU is asking for, calculate your Scope 3 emissions and manage your supply chain sustainability from start to finish.

Sustainability is now measured in your supply chain

According to CDP data, the emissions arising from a company's supply chain are on average more than 11 times those coming out of its own operations. That is why buyers in the EU are turning to their suppliers in order to meet their climate targets, and sharing carbon data has in many sectors become a condition of the supply contract.

To keep winning the business, what you need to do is measure the emissions of your own supply chain and give your buyer consistent, verifiable data. Karbonsa manages this process on your behalf from end to end, from collecting supplier data through to the Scope 3 calculation and responses to buyer requests.

WHAT HAS CHANGED FOR YOU

What does your buyer in the EU now ask for?

  • Real carbon data. Instead of sector averages, it asks for the real carbon data you produce yourself, at product or supplier level.
  • Verifiable infrastructure. It expects the emissions data you provide to be consistent with international standards and open to audit.
  • Cost risk. Where data arrives late or incomplete, it faces additional financial obligations at the EU border based on high default values.
  • Commercial advantage. Suppliers that provide transparent and verifiable data move straight ahead when contracts are renewed and new orders are placed.
Let Us Assess Your Situation

Where do supply chain emissions build up?

Scope 3 gathers the indirect emissions in the value chain under fifteen categories. In most manufacturing companies the burden is concentrated in the following areas.

Purchased goods and services

Your raw material and component suppliers usually carry the largest share.

Logistics and distribution

The transport, storage and distribution of inputs and products.

Product use and end of life

The service life and disposal stage of the product you sell.

Capital goods and others

Capital goods, business travel and other indirect sources in the chain.

Not: We measure the Scope 1 and Scope 2 emissions coming from your own facilities and energy use with our Corporate Carbon Footprint Calculation (ISO 14064) service. Scope 3 completes that picture on the supply chain side, and the largest share of the total footprint usually comes from here.

If you want to track your supplier and Scope 3 data yourself, the web based Karbonsa Platform is at your service with a free plan.

Manage Your Scope 3 Emissions

The work Karbonsa takes on in the supply chain process

We run the process on your behalf from start to finish.

Supplier carbon data collection

We identify your priority suppliers and collect product and process level emissions data from them using a standard template. We check the quality of the incoming data and fill any gaps with sector data.

Scope 3 emissions calculation

We calculate the indirect emissions in your value chain in line with the GHG Protocol Corporate Value Chain standard. We set out which category carries the largest share of your footprint.

Supplier assessment and surveys

We assess your suppliers against environmental, social and governance criteria and group them by their level of risk. That makes it clear which supplier you should work with first.

Supplier training and capacity building

Most of the suppliers you will ask for data are as new to this subject as you are. We explain to them how to prepare the data and make it easier for them to take part in the process.

Preparing responses to buyer requests

We prepare the data set and documentation you need in order to respond consistently to the EcoVadis, CDP or CBAM data requests coming from your buyer in the EU.

Hotspot analysis and reduction

We identify the suppliers and categories where emissions are concentrated and guide you towards the reduction steps that will deliver the highest impact.

Supply chain data takes on its full meaning alongside your own corporate footprint. Your company wide emissions are measured by Corporate Carbon Footprint Calculation, while the environmental impact of a single product is set out in detail through Life Cycle Assessment. When exporting to the EU this data feeds directly into the CBAM advisory process, while we build the wider sustainability strategy on the ESG Strategy and Management Advisory side.

FAQ

Frequently Asked Questions

Scope 3 covers the indirect emissions that arise along the value chain, outside a company's own facilities and vehicles. They are gathered under fifteen categories, from purchased goods and services to logistics, and from the use of the product to its end of life. The GHG Protocol Corporate Value Chain standard defines these categories. In most manufacturing companies the largest share of the total carbon footprint comes from here.
