Climate Transition: How we are adapting to limit the impact of our activities (1/4)

Over a year ago, we committed to align our activities with the most ambitious climate science scenario: limiting the global temperature rise to 1.5°C. Through a series of articles, we will present our Climate Change ambition and strategy, the levers we focus on to get there and the progress we have already made.

Improving efficiency and investing in low-carbon energy sources

Greenhouse gasses are generated daily across Imerys by the consumption of energy that our activities require and the emissions generated by our chemical processes. Given the urgent need to tackle climate change, we decided 18 months ago to go one step further and adopt a courageous objective: to align our activities with the 1.5°C trajectory. It starts with adapting the way we operate by making sure to use low-carbon energy sources and also in a more efficient way.

We set up a robust strategy to achieve our targets and supported by an investment plan of 20 to 25 million euros a year until 2030. We are on the right path thanks to the decarbonization projects that are progressively being deployed in our sites with an effective positive impact in terms of emissions reduction.

Imerys and Climate Change: All you need to know is published in our first report 

We published on May 14 our first Climate Transition Plan report. It illustrates our progress with concrete examples. This report should be seen as a guide to understand our ambition, our objectives and the resources deployed to achieve them through our main decarbonization levers:

  • Energy efficiency and recovery
  • Low-carbon and renewable electricity
  • Fuel switching and biomass use
  • Electrification
  • Process innovation.

This is illustrated via projects we have implemented across the Group, with measured impacts. It's a great demonstration of the collective work and commitment of our teams.

I am convinced that strength lies in collective effort. It's through teamwork and partnerships that we can move things forward, both within our company and in collaboration with all our stakeholders

While implementing our roadmap to reduce Scope 1 & 2 emissions, we also defined our strategy and objectives to reduce the Greenhouse Gases emissions generated in our upstream and downstream supply chain (Scope 3). We ambition to cut 25% of these emissions by 2030 from a 2021 base year.


The 2015 Paris Agreement aims to strengthen the international response to the threat of climate change by limiting the global temperature rise to "well below 2°C" and calls on countries to continue their efforts to limit the rise in temperature to 1.5°C. Scientific studies have shown that keeping global warming below 1.5°C would significantly reduce the negative consequences as compared to 2°C or more, including reducing the risks to ecosystems, human populations and global economies.

Imerys' emissions are categorized into three scopes: 

  • Scope 1 includes direct emissions from fuel combustion and certain chemical processes. 
  • Scope 2 covers indirect emissions from purchased electricity and steam consumption
  • Scope 3 encompasses a wide range of greenhouse gas emissions across the supply chain, including purchased goods and services, transportation, waste, business travel, and product lifecycle.
