SIBUR has offset the carbon footprint of the Russian delegation's participation in COP29 – the 29th Conference of the Parties to the UN Framework Convention on Climate Change, which took place in Azerbaijan. This marks the first carbon-neutral delegation with a confirmed international verification in the Conference's history. The delegation's carbon footprint amounted to 970 tonnes of CO₂ equivalent.

The offset was achieved using carbon units generated through a climate project focused on improving energy efficiency at SIBUR-Neftekhim. These carbon units were debited from the Company's account in the Russian Registry.

Kept performed the carbon footprint calculation, while TÜV AUSTRIA Standards & Compliance provided verification of the carbon neutrality statement. The carbon offset certificate is accessible on the UN Global Compact Network Russia website. The process is coordinated by the Federal Service for Hydrometeorology and Environmental Monitoring of Russia, which provides support to the Russian delegation and working group.
