Greenhouse Gas Emissions

Greenhouse Gas Emissions

Greenhouse Gas Emissions

With challenges posed by global climate change, enterprises must reduce greenhouse gas emissions from operations to mitigate their negative impacts on the climate. Suppose Scopes 1, 2, and 3 emissions continue to increase annually. In that case, our company may face rising carbon fee (tax) costs, inability to meet customer (market) demands, and failure to comply with our publicly committed carbon reduction targets, among other regulatory, reputational, and market risks. As a comprehensive technology service provider in the information and communication technology industry, offering customized product development and services to global clients, our capability for low-carbon manufacturing and green product services will directly impact our market competitiveness. Therefore, we conduct annual carbon inventories and formulate short-term, medium-term, and long-term carbon reduction plans to meet the expectations of our broad range of stakeholders.
