(b) Effective 2022, the internal CO2 price was increased from €75 to €100 per metric ton CO2 eq. As a consequence, the level for 2021 has
been restated to 50% (from 53%).

materials, produced with renewable energy, with increasing longevity in the use phase or enabling recycling at the end of life.
(d)The apparent increase of freshwater withdrawal in 2022 is mainly due to a stricter application of internal reporting rules for freshwater
pumped by Solvay but sold to third parties. From the 330 million cubic meters for 2022, 30 (9%) is sold to third parties. The total freshwater
withdrawal in 2022 is slightly lower than in 2021 (-1.7 million cubic meters or -0.5%) at constant scope and methodology.

Resources  

In 2022, the proportion of sales from sustainable solutions reached 55%, a 5% annual increase. It reflects the
organic growth in the automotive and battery market with Specialty Polymers and Silica, in the agro market with
Novecare, in air and water treatments with Peroxides and Soda Ash & Derivatives.

The group made significant progress in circularity with a 9.3% of its sales of circular products. This result is
getting closer to the 2030 target, with part of this progress related to methodology improvement. Solvay is
already a market leader in some bio-polymers like guar, bio-sourced solvents and natural vanillin. Solvay is also
investing in a powerful Rare Earths hub in La Rochelle, France to play a proactive role in the recycling of magnets.
The collaboration between the Materials business and the French startup Carbios on the enzymatic recycling of
polymers is another example. Finally, the new Solvay growth platform on Renewable Materials and Biotechnology
will facilitate the development of safer chemicals, foster more environmentally-friendly solutions and enhance
circularity.

Innovation to develop more sustainable solutions is a continuous process for Solvay teams partnering with
customers to develop tailor-mode solutions. In 2022 Solvay opened a new Application development center in
Alpharetta, Georgia, in the US. The Group is also investing in the upgrade of the 160 year-old soda ash
manufacturing process to reduce the CO2 emissions by 50%, while reducing resource consumption and eliminating
limestone residues. A pilot is being implemented at the Dombasle, France site.

In 2022, the apparent increase of freshwater withdrawal in 2022 is mainly due to a stricter application of internal
reporting rules for freshwater pumped by Solvay but sold to third parties. Solvay launched various water
management initiatives to address water scarcity like the creation of a dashboard that monitors around 90% of
the Group’s daily freshwater intake. Solvay also conducted a review of water risks. Seven sites have designed
roadmaps to improve their resilience, with the potential to achieve 30 million cubic meters in water intake
reduction.

In 2022, Solvay exceeded its 2030 target with a -36% reduction of its non-recoverable industrial waste.
Valorization, recycling and use in waste-to-energy programs are the key levers to reach the zero waste to landfill
target. For example, the calcium fluoride (CaF2)-rich sludge produced at the Panoli site (India) is now reused as
an additive in a cement plant instead of going to landfill. Another example is in the Augusta US site, where the
volume of the waste polymer stream has decreased by 76% compared to 2021. Finally, the Collonges site (France)
is valorizing the discarded silica by providing to customers a new range of products for other uses.

Solvay actions to foster a better life

In 2022, the number of injuries has decreased to 0.34 (versus 0.43 in 2021), despite higher production levels.
Despite all efforts, a dramatic accident occurred. The Group triggered a strong action plan to raise the bar to reach
the zero accident target.

Regarding Diversity, Equity and Inclusion (DEI), major milestones have been achieved this year. The Group took
concrete actions to improve pay equity, created the “homogeneity index”, achieved parity at the senior
management level (SLC) and included the DEI roadmap within the 15% One Planet part of the Short Term
Incentive.

Solvay also has nine Employee Resource Groups (ERG), which are grassroots groups led and run by employees
that encourage employees to recognize and celebrate diversity, which is a critical component to guide the DEI
journey. The different ERGs have suggested a DEI pledge that has been signed by the entire Senior Leadership
Team.

In 2022, more than 100 sites, reaching more than 40% of Solvay’s global workforce, devoted time to improving
their awareness of Diversity Equity and Inclusion (DEI) as part of Solvay’s One Dignity initiative. Their participation
was converted into a €50,000 donation, which will be spent with local charities promoting DEI in the 14 countries
that had the most participation.

The Group provided support for its employees with €9.5 million to be distributed among the people most affected
by inflation. Solvay launched its first employee share plan in 2022, achieving an impressive participation rate of
27.7%, which is ahead of the benchmark for similar initiatives. And finally, Solvay increased its Global Performance
Sharing (GPS) Plan budget to €15 million, for the “non-executive” employees.

In 2022, the Group renewed its Solvay Global Forum and Global Framework agreements with IndustriAll Global
Union, the global union for the chemicals industry.
