StrategyThe production process of electronic specialty gases usually involves high carbon emission, and the emission sources are complex. Withthe ever-increasing market demands for electronic specialty gases, failure in effective control of carbon emissions will lead to furtherhike of the total carbon emissions in the industry. This not only goes against the national "Dual Carbon" strategy, but likely triggers policyconstraints such as carbon tariff, thereby raising the Company's operating costs. Huate Gas analyzed both risks and opportunities,referred to studies of climate, macro environment, industrial policies, etc., and took into account its business realities to assess theimpact of climate change on the corporate business. Then, the Company incorporated the assessment results into the strategicresilience planning, and accordingly adjusted its business development strategy and resource allocation, which helped significantlyenhance its adaptability and resilience in responding to climate change.

● Low-Carbon PublicityFocusing on the corporate development strategy, Huate Gas actively conducts energy conservation and carbon reductiontraining & publicity work, makes every effort to urge employees to develop good habits of spontaneously taking actions forcarbon reduction, and ensures the fulfillment of the Company's development goals.In addition, the Company attaches great importance to low-carbon operation. It always takes "Conserving Resources, Eliminat-ing Waste" as the guiding ideology in routine work, keeps advocating the green office motto “Low-carbon Economy, EnergyConservation, Consumption Reduction” among employees, and strictly controls the power consumption of lighting and electri-cal equipment in the office area. Besides that, the Company encourages employees to put energy conservation into practice,and enhances employees' awareness of energy conservation and emission reduction. The Company also organizes activitiesrelated to energy conservation and carbon reduction at regular intervals, in order to deepen employees' understanding of thesignificance of energy conservation and emission reduction, and to urge the enterprise to achieve the carbon neutrality goalin a more efficient manner.

The Company holds fast to the bottom line of environmental protection in economicdevelopment and vigorously promotes its long-term sustainable development.

Leakage risks are mainly caused bychemical spills, fire accidents, andimproper treatment of wastewaterand waste gas. Chemical spills maylead to pollutants’ entry into surfacewater through the rainwaterpipeline. Hazardous waste such asfirefighting sand, which has notbeen properly handled, may affectthe environment. After beingvolatilized, spilled chemicals mayalso pollute the atmosphere. In theevent of a fire accident, firefightingwastewater with chemicals may bedischarged into surface waterthrough the rainwater pipeline, anda large amount of toxic and harmfulsmoke will be generated to pollutethe air.

Waste Management

Based on relevant laws, regulations and industry standards, Huate Gas has formulated the Procedure for the Control of Waste Management toimplement the life-cycle management of the waste generated during the production and operation process, and clarify the responsibili-ties of each department and each position in each link. In order to achieve precise control over waste, the Company has established astandardized waste management ledger to record in detail information such as the waste type, quantity, flow direction, storage, utiliza-tion and disposal. In addition, the Company has adopted information technology means to realize the traceability and availability ofwaste information.

Noise ManagementDuring the corporate operation, Huate Gas’s noise mainly comes from the operation of vehicles and mechanical equipment. Toeffectively alleviate the adverse impact of noise on the surrounding acoustic environment, the Company, in accordance with relevantregulations, conducts precise monitoring over the ambient noise at the factory boundary on a regular basis. In addition, the Companyprefers low-noise and environment-friendly equipment. For the existing equipment, the Company installs professional noise reductionfacilities such as high-efficiency sound insulation enclosure and vibration-damping pad to effectively suppress the noise generationand transmission, aiming to ensure that the noise at the factory boundary complies with the Class 2 standards of the Emission Standardfor Industrial Enterprises Noise at Boundary (GB12348-2008).
