The Environmental Protection Administration (EPA) yesterday released statistics on reductions to last year’s electricity and water consumption as a result of Taiwanese purchasing products with EPA-certified “green marks,” which showed that the public can reduce carbon dioxide emissions by 223,000 tonnes per month if all 8.4 million households use such products.
The estimate was roughly equal to 603 times the carbon dioxide absorbed by trees in Taipei’s Daan Forest Park every year, the EPA said.
In addition, if every household were to change to green mark products, they would save the nation as much as 312 million kilowatt-hours (kWh) of electricity per month, enough to cover the demand of the about 1 million households in Taipei for a month.

They would also save a total of 44.1 million tonnes of water, the equivalent of the combined capacity of 17,669 standard swimming pools, the agency said.
The products reviewed by the EPA to determine whether they meet the requirements to receive a green mark include information technology products, such as computers and monitors, as well as a range of household items, including water dispensers, fluorescent lights, electric fans and air conditioners, the EPA said.
Paper products made of recycled materials are also eligible for the vetting process, it added.
Department of Supervision, Evaluation and Dispute Resolution Director-General Hsiao Hui-chuan (蕭慧娟) said that if a household were to replace two old, energy-inefficient air conditioners with green mark units, it would be able to reduce its electricity bill by 10 percent per year.
She said that green mark products are energy efficient and therefore generate less carbon dioxide.
For example, an EPA-approved computer monitor can save at least 1kWh of electricity and produces 0.69kg less carbon dioxide per month, while a desktop computer certified by the agency can reduce electricity consumption by 3.28kWh and carbon dioxide generation by 2.26kg compared with less environmentally friendly models, Hsiao said.
The difference in energy efficiency is most obvious in refrigerators, with green mark refrigerators reducing consumption of electricity by at least 10kWh per month and carbon dioxide generation by 6.9kg, followed by dehumidifiers, which can cut at least 9.72kWh and 6.72kg of carbon dioxide monthly.
The EPA said eco-friendly products have so far helped reduce the nation’s energy consumption by 144.9 million kilowatt-hours and carbon dioxide emissions by 104,000 tonnes. The agency based its calculations on the number of green mark products sold over the past year multiplied by the expected service life of the products.
Consumers can identify EPA-certified products by the green mark logo of the Earth wrapped in a green leaf.
LONG-TERM ALLIANCE: Using the company’s virtual development tools would help reduce cost and spur innovation at the research institute, an official said The Taiwan Semiconductor Research Institute (TSRI) has partnered with Synopsys Taiwan to accelerate the development of next-generation semiconductors, with researchers being allowed to use the chip design company’s simulation tools, the National Applied Research Laboratories said yesterday. The institute is one of eight laboratories of the national research agency. The institute has signed a contract with Synopsys that allows researchers to use its simulation software — Sentaurus TCAD and Quantum ATK — free of charge, the agency said in a news release. The Synopsys Web site describes Sentaurus TCAD as an advanced 1D, 2D and 3D process simulator for developing and optimizing chip
MONITORED BY JETS: Chinese aircraft included Y-20 aerial refueling aircraft, suggesting that China refueled its short-range jets during flight The air force scrambled again yesterday to warn away 27 Chinese aircraft that entered its air defense identification zone (ADIZ), the Ministry of National Defense said, the latest increase in tensions across the sensitive Taiwan Strait. Taiwan has complained for a year or more of repeated missions by China’s air force near the nation, often in the southwestern part of its ADIZ, close to the Taiwan-controlled Pratas Islands (Dongsha Islands, 東沙群島). Over a four-day period beginning on Oct. 1, when China marked its national day, Taiwan said that nearly 150 Chinese People’s Liberation Army (PLA) military aircraft entered its ADIZ, not territorial
DESTABILIZING: Beijing’s efforts to choke Taiwan, pressure its friends and hamper its democracy are a threat to the world, AIT Director Sandra Oudkirk said China’s provocative military activities near Taiwan are destabilizing and risk “miscalculation,” American Institute in Taiwan (AIT) Director Sandra Oudkirk said yesterday, reiterating the US’ objection to any unilateral changes to the “status quo” in the Taiwan Strait. Oudkirk made the remarks in a speech at the annual conference of the Association of International Relations in Taipei. “In the Indo-Pacific region, America’s effort to resolve and manage differences with the leadership of the People’s Republic of [PRC] faces distinct challenges,” she said, referencing a range of actions by China that she said run counter to the shared values and interests of the
EXTRADITION POSSIBLE? The suspect, who is quarantining upon arrival in Xiamen, is accused of killing a coffee trader on a street near his house in Sindian District The suspect in an execution-style murder of a businessman in New Taipei City’s Sindian District (新店) has fled to China and officials are negotiating his extradition, the New Taipei City Police Department said on Tuesday. The suspect, surnamed Huang (黃), took a flight from Taiwan Taoyuan International Airport at 2pm on that day to Xiamen, where he is staying in a quarantine hotel, as required by Chinese COVID-19 regulations, the department said. Investigators accuse Huang of shooting dead a local coffee trader surnamed He (何) on a street near his residence when he was returning from dropping off his daughter at her
