GHG Emission Disclosure

GHG Emission Disclosure

Climate change is one of the world''s most important environmental issues in recent years. In the Fifth Assessment Report (AR5) announced in 2013 by the Intergovernmental Panel on Climate Change (IPCC) in Stockholm, Sweden, the IPCC believed that from the observation in the late 20th centry, the likelihood of human activities casing the increase in global average temperature has risen from very likely (>90%) in the AR4 to extremely likely (>95%), and the increase in global average temperature will significantly change the global climate, including the increase in extreme weathers such as uneven rainfalls, heavy rains and droughts. Therefore, many countries develop various flexible reduction methods to achieve the purpose of Greenhouse Gas (GHG) Management and GHG reduction.

Since ASUSTeK is not in energy-intensive industry, we have no immediate risk of emissions restriction from Kyoto Protocol. However, we have been long concerned about the issue of global warming and are willing to spare no effort to help slow down the greenhouse effect.  ASUSTeK performs GHG inventory according to ISO 14064-1 and establishes a database to keep the historical records. This will help ASUSTeK to identify sources of emissions and to analyze data, thus will be able to set up reduction plan and goal.

The boundary defined was mainly all ASUSTeK owned or leased buildings in Headquarters, Taiwan. The sources of emissions were identified as followed:

  • Direct emission (Scope 1): GHG emissions from sources owned or controlled by the entity within the organizational boundary
  • Energy indirect emission (Scope 2): GHG emissions from consumption of purchased electricity by the organization
  • Other indirect emission (Scope 3): other GHG emissions not covered by Scope 2

For Taiwan, we adopted the Global Warming Potential (GWP) coefficient (KgCOe/KWh) for calculating energy consumption and GHG emissions with reference to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories, 2007 IPCC AR4 100-yr, and Energy Statistics Handbook 2013 published by the Bureau of Energy, Ministry of Economic Affairs of Taiwan for 2014 data.

Sources of Scope 1 emissions

  • Diesel: consuming 228 liters, producing 1 metric tonnes CO2-e
  • Gasoline: consuming 8,671 liters, producing 20 metric tonnes CO2-e
  • Others: producing 78 metric tonnes CO2-e

Sources of Scope 2 emissions

  • Electricity: consuming 21,488 MWh, producing 11,217 metric tonnes CO2-e

Sources of Scope 3 emissions

  • Employee business travel: 39,927 passenger-thousandmile, producing 122,338 metric tonnes CO2-e.

Compared to 2013, we used 1,281MWh more electricity and emitted 3.6% more GHGs (Scopes 1 and 2 together) in 2014 for the following reasons:

  • To further conserve energy, we have changed gas into electric heater for the swimming pool and shower equipment in our gymnasium. As a result, we successfully reduced Scope 1 emissions, while electricity consumption increased.
  • In 2014, we recruited employees for business growth and also rented many offices outside of the headquarter. This was the main cause of the increase in electricity consumption.
