The SBTi’s Target Validation Team has classified Principle Cleaning Services’ scope 1 and 2 near-term target ambition and has determined that it is in line with a 1.5°C trajectory. Our scope 1, 2, and 3 long-term target ambition has also been evaluated, and the SBTi’s Target Validation Team has determined our long-term target(s) are aligned with the SBTi’s 1.5°C mitigation pathways for reaching net-zero by 2050 or sooner.
