Greenhouse Gas Inventory

GHG Inventory and Assurance

Since 2011, Acer has contracted a third-party verification agency with Taiwan EPA accreditation to undertake external GHG Protocol Scope 1, 2, and 3 emissions inventory and assurance.

In 2019, we found that the Acer Group was responsible for 3,540.22 tons of Scope 1 and 10,223.617 tons of Scope 2 (market-based) carbon emissions. Our Scope1 and scope 2 emissions totaled 13,763.83 tons (market-based), with Scope 1 emissions primarily from North American and European natural gas usage and global combustion activity, and Scope 2 electricity usage accounting for approximately 74.28% of the combined emissions of the two. Total emissions in 2019 were reduced 57.18 % on the baseline year and 14.30% less than 2018; per capita emissions were approximately 1.901 tons, about 4.95% lower than adjusted 2018 figures.

Annual Group Greenhouse Gas Emissions and Reduction Targets

In addition, in accordance with GHG Protocol Scope 3 principles, we carry out inventory of emissions produced by staff business flights, product and service purchases, product shipping, leased assets, product energy consumption, waste products, and power & fuel. Through inspections, we better understand how to control the carbon risks and opportunities in the value chain, which will further help in reduction strategies. In addition, per GHG Protocol Scope 3 principles, we undertake an inventory of items including staff business flights; product and service procurement; product shipping, energy consumption, and end-of-life; operational waste; electricity and fuel; and leased assets. Among these, product energy consumption creates the most significant amount of emissions, with our four main hardware categories (notebooks, desktops, all-in-ones, and displays) accounting for a total of approximately 1.08 billion kWh of power consumption in 2019. Through more thorough Scope 3 inventories, we can better understand how to control carbon risks and opportunities in the value chain, which will further help with reduction strategies.

Scope 3 Greenhouse Gas Emissions Sources and Levels


Staff business fights

Emissions (tons): 5,936.80

Total Emissions, Including Global Employee Business Flights


Product and service purchases

Emissions (tons): 57,711.83

Based on ODM allocation data on major products (notebooks, desktops, monitors, and projectors) from 10 companies in 2019


Product shipping

Covers all regions of the world including Taiwan, Europe-Africa-Middle East Region, the Americas, China, and Asia Pacific

Product Energy Consumption

Emissions (tons): 1,785,738.68

Takes the annual shipping volume of major products (notebooks, desktops, all-in-one, and displays) and multiplies that by annual TEC

Waste Products

Emissions (tons): 36.31

Mainly general waste produced in the Taiwan region

Power and Fuel

Emissions (tons): 2,846.44

Mainly consumption of natural gas, gasoline, diesel, and electricity in the Taiwan region

Mainly desktop and notebook computers in the Taiwan region

Product Carbon Footprint Disclosure

In 2015, we took the lead in joining the Carbon Footprint Calculation Platform established by the Taiwanese EPA. With the cooperation of our major suppliers, we have set out a plan to broaden the carbon footprint inventory across indicator products, completing a carbon footprint report for the Chromebook C740. This cloud-based platform can effectively integrate many parties in the supply chain, providing timely calculation services and greatly reducing operating expenses, as well as accelerating inventory work.

This effort focuses on the office mode of the model, and the results have shown that carbon emissions across the product' lifecycle total approximately 123.70 kg. The raw materials and the using phases account for greater proportions of that figure, specifically 64.50% and 33.97% of total emissions respectively. The lightweight, quick-booting, quick-connecting nature of the product and the more streamlined components used therein (in comparison with ordinary notebooks) may help reduce the emissions at the raw materials and user ends.

Chromebook C740 Lifecycle Carbon Emissions

To meet the requirements of the EPEAT standard and make our products more competitive in commercial bidding, since 2019, we have also enacted quantitative life cycle assessment for products. The first product for which this was completed was the Desktop PC VX4660G (or Veriton X4660G). In cooperation with the Industrial Technology Research Institute, we carried out a full cradle-to-grave life cycle inventory and analysis of this product in line with ISO 14040:2006 and ISO 14044:2006 standards. Through the DoITPro database (v2019.0003), we undertook second-level data conversion, finding the following main overall environmental impacts: carbon emissions of 461.3 kgCO2e; 0.39 m3 equivalent of water; and mineral, metal, and fossil resource consumption of 0.0131antimony (Sb) equivalent.
