Illumina Among First in the World to Receive Approval of Science-Based Net-Zero Target

The Science Based Targets initiative has validated Illumina's targets to reach Net-Zero greenhouse gas emissions by 2050

SINGAPORE,July 29,2022 --Illumina,Inc. (NASDAQ: ILMN),a global leader in DNA sequencing and array-based technologies,announced today it is among the first group of companies worldwide to receive approval of its net-zero targets by the Science Based Targets initiative (SBTi). This includes validation of Illumina's corporate greenhouse gas (GHG) emissions reduction targets by the organization.

The SBTi is a global body that enables businesses to set ambitious emissions reduction targets in line with the latest climate science. Its Net-Zero Standard is the world's first science-based certification of companies' net-zero targets in line with the Paris Agreement's goal of keeping planetary warming to 1.5°C.

"Illumina proudly joins the SBTi as the first genomics company in the world with a verified,science-based,net-zero target," said John Frank,Chief Public Affairs Officer of Illumina."We chose to pursue this approach for our net-zero target to demonstrate that our long-term climate targets are credible,ambitious,and will have a positive impact on human health and our planet."
