 Greenhouse Gas Emissions

The total greenhouse gas emission is 832,969.98 t-CO2e in 2017, including CO2, CH4, N2O, HFCs, PFCs, and SF6. As an integrated telecom carrier, most energy source consumed by Chunghwa Telecom is electricity, which is classified as Scope 2 (purchased electricity) gas emission and accounted for 96.3% of total gas emission. Scope 1 gas emission is normally sourced from greenhouse gas emissions such as offices and accounted for 3.7% of total gas emissions

Green Energy

Being the largest telecommunication carrier in Taiwan, Chunghwa Telecom recognizes its duty to support government policies with strategies and goals set up to guide our actions. We are also taking count of proprietary buildings that would be suitable for the construction of solar power system; furthermore, new IDC servers are being constructed preferably using renewable energy.

Chunghwa Telecom has been applying its long-accumulated ICT background into the construction of solar power stations for many years. By the end of 2017, the Company had 45 solar power stations throughout Taiwan with a total rated capacity of 527 kWp. We also aim to assist government agencies and private businesses in the coordination of photovoltaic projects.

Moreover, driven by our care towards environmental sustainability, we actively support the government’s Green Power Purchasing System by purchasing 6 million kWh of green electricity in 2017.

Water Resource Management

Water usage at Chunghwa Telecom is mostly for domestic purpose. Apart from bathroom use, air conditioner cooling accounts for another major water use. Given the ongoing increase in business activities and manpower, there is limited room for water reduction besides recovery of rainwater and cooling water. We have identified water resources as part of our management focus, and introduced many initiatives to improve water efficiencies, such as water conservation measures, centralized water bill management, and water saving goals. Apart from adding a new water leakage detection feature, we have also incorporated water usage monitoring into our environmental sustainability system. Data collected from these two functions are analyzed and managed. Other conservation measures such as recycling and reuse of rainwater and domestic effluents are also being implemented on an on-going basis.

Waste Management

Understanding the importance of resources reduction, recycle and reuse, Chunghwa Telecom combined our five-year environmental sustainability development plan and EARTH system to manage the use of resources and control energy efficiency, while conducting systematic management on recycled and waste treatment. Chunghwa Telecom designated professional waste treatment company to transport our daily waste to landfills or incinerator for necessary treatment. For recyclable waste, the contracting cleaning company is designated for the classification and disposal treatment
