Environmental KPIs

WE Soda has strong environmental and sustainability credentials, which are best-in-class across the soda ash industry.1 For our full range of environmental performance indictors, you can read our 2022 Annual Report.

Water stewardship

Water is an essential input to our production process, as well as being important to the local communities in which we operate.

Because climate change is expected to increase the pressure on water resources and increase the risk of water scarcity, it is important that we operate with a water stewardship strategy designed to protect and preserve the water resources of our communities and our operations.

During 2022, our total water intensity was approximately 2.04, less than one-quarter of the water intensity of synthetic soda ash producers.

Within the next five years we will reduce our water intensity by 20% relative to a 2022 baseline.

Reducing our CO₂e emissions is a priority.

We already produce soda ash with low Scope 1 & 2 CO₂e emissions intensity by comparison with synthetic soda ash producers.

The majority of CO₂ released during our soda ash production process is captured and re-used in the production of sodium bicarbonate.

  • Our Scope 1 & 2 CO₂e emissions intensity was approximately 0.34 in 2022 – around one third of synthetic producers.

  • Our Scope 1, 2 & 3 CO₂e emissions intensity was approximately 0.51 in 2022 – around half that of synthetic producers.2

Our emissions targets:
20% reduction of Scope 1 and 2 intensity in 5 years and 40% in 10 years.
Net Zero CO₂e emissions by 2050.

We are committed to increasing our renewable energy capacity and usage. It is a fundamental element of our sustainability strategy.

We have installed 7MW of PV solar generation capacity at our facilities which came on-stream during the first quarter of 2023, with a further 3MW planned by year end 2023.

At our Turkish operations we estimate that, by 2027 we can deliver 200MW of installed solar and wind capacity.

In 2022 we announced West Soda, which will be the first soda ash production facility globally to source all of its electrical power needs entirely from renewable sources.

Waste management

We approach waste with a circular mindset, this reduces the amount of waste our sites generate and opens additional revenue streams.

We take measures to recover, re-use or recycle the waste generated in our operations, reducing the amount of waste that we send for disposal.

Where possible, we aim to apply the principles of circular economy, for example:

  • Production of sodium bicarbonate using recycled CO₂

  • Reuse of purge in the production of caustic soda

  • Sale of fly ash for use in cement production

  • Refinement and sale of industrial salt

  • Sale of calcium carbonate for flue gas desulphurisation

In 2022 we recycled, reused and repurposed 1.1m tonnes of waste, and disposed of less than 0.1m tonnes of waste.

Our broader environmental commitments

Increasing and preserving biodiversity and improving air quality are the focus of several of our projects.


In 2016, Kazan Soda initiated a project focusing on preserving biodiversity in the area surrounding our production plant. The project identified six endemic plans which required specific protection plans. To date, we have established a 10,000m2 conservation area and have started working with local schools to provide education on the importance of biodiversity and protecting endemic species.

Air quality

We regularly sample and monitor the effects that our activities have on the environment. At Eti Soda, dust, CO, SO₂ and NO₂ parameters are constantly monitored. In 2022, we upgraded the dust removal system from the main stack of the processing plant, reducing dust emissions.

1 We determine our impact on nature and the environment in comparison to our peers through the assessment of our energy intensity of 4.44, Scope 1 & 2 COe emissions intensity of 0.343, water intensity of 2.04, and total waste directed to disposal of 73,384 mt (in each case for 2022) as these metrics provide a relative and comparable measure of performance across our industry.
