Our carbon footprint

Our business, our responsibility

At HASLE Refractories, we are aware that our activities have an impact on the environment — or in other words: A carbon footprint. We are committed to reducing our environmental impact by improving energy efficiency and managing our carbon footprint across operations and products.

We track and report our greenhouse gas (GHG) emissions in alignment with the GHG Protocol, covering Scope 1, Scope 2, and Scope 3 emissions.

Scope 1: includes direct emissions from our company vehicles (including loaders and other machines used at our production site) and LPG-fueled furnaces used in our precast manufacturing.
Scope 2: covers indirect emissions from purchased dsitrict-heating and electricity; for the latter, we apply the location-
based method, which accounts for the average emissions intensity of the electricity grids where our operations take place.
Scope 3: activities in our value chains represent the majority of our total emissions (~98%) and includes raw material sourcing, transportation, packaging, and other value chain activities.

The table below provides an overview of our gross Greenhouse Gass emissions, covering Scope 1, Scope 2, and Scope 3.

HASLE Green House Gas emissions inventory

Category	2022 (tCO₂e)	2023 (tCO₂e)	2024 (tCO₂e)
Scope 1 (Direct emissions)	115	79	145
Scope 2 (Energy-related indirect)	50	16	16
Scope 3 (Other indirect)	8.879	8.763	8.945
Total	9.045	8.878	9.107

HASLE Greenhouse Gas Emissions Inventory (2024)

Category	2024 (tCO₂e)
Scope 1 (Direct emissions)	145
Scope 2 (Energy-related indirect)	16
Scope 3 (Other indirect)	8.945
Total	9.107

It is important to note, these figures and data have been prepared internally by HASLE Refractories and has not been externally audited or independently verified. We continuously improve our emission estimates by collaborating with suppliers to obtain primary emission factors. Where not available, we rely on credible secondary data. For transport, we apply the tonnes-kilometre method for both upstream and downstream shipments. While these methodologies mean the data is not 100% precise, it represents the best available estimate of our GHG emissions.

Our most recent inventory (2024) shows total emissions of 9,107 tons CO₂e, with Scope 3 emissions being primarily driven by the use of calcined and synthetically produced raw materials (such as mulite and silicon carbide) as well as global transportation. you can see the split between the different subcategories in the diagram below.

Product-specific carbon footprint

A key result of our carbon mapping initiative is the ability to calculate product-specific cradle-to-gate CO₂e values across our castable and precast range. We have developed a dedicated CO₂e estimation tool based on our corporate carbon inventory.

Methodology

The methodology follows the principles of life cycle assessment (LCA) framework outlined in EN 15804, covering the key phases

A1: Raw material extraction and production
A2: Transportation to HASLE
A3: Manufacturing at our facility

Outcome

Our current product range shows a CO₂ footprint variation from 265 kg CO₂e per tonne to 4,600 kg CO₂e per tonne of low-cement castable, depending on raw material composition and processing requirements. For customers seeking more detailed insights, product-specific CO₂e data can be provided upon request.
