(hereinafter referred to as "HitGen", SSE: 688222.SH), announced it has officially submitted its commitment letter to the Science Based Targets initiative (SBTi). HitGen has pledged to set near-term science-based targets within the next two years, aligned with the SBTi's stringent criteria. This commitment entails the future development and implementation of a series of emission reduction measures designed to cut the company's greenhouse gas emissions across its value chain to a level consistent with the 1.5°C temperature goal set forth in the Paris Agreement.
