Completion of upgrades to four boiler units at the coal-fired Taichung Power Plant earlier this year would reduce its air pollutant emissions by 80 percent over the next five years, Premier Su Tseng-chang (蘇貞昌) told a weekly Cabinet meeting on Thursday.
Su told the meeting that the plant’s emissions last year had decreased by half from 2016 levels, Executive Yuan spokesman Ting Yi-ming (丁怡銘) quoted Su as saying, adding that the Executive Yuan in May last year agreed to budget NT$15 billion (US$508.37 million at the current exchange rate) to fund the upgrading of the plant’s boiler units No. 5 to No. 10.
The government is responsible for improving air quality by reducing air pollution, Su said.
Environmental advocates have repeatedly complained about pollution by the Taichung power plant and called for the reduction of the use of coal.
About 40 percent of Taiwan’s air pollution originates outside of the nation’s borders and is difficult to control, but through interdepartmental collaboration and increased dialogue between the central and local governments, it is possible to implement policies targeting the three main sources of controllable air pollution, Su said.
These collaborations have produced significant results, with red alerts for fine particulate matter smaller than 2.5 micrometers (PM2.5) improving by 85 percent from 997 times in 2015 to 146 times last year, Su said.
Southern Taiwan, which is usually more affected by PM2.5 pollution during autumn, saw zero red alerts last year, compared with 120 times in 2018, while the Yunlin-Chiayi-Tainan area saw red alerts drop from 99 to 9 times last year, he said.
Citing statistics from Kaohsiung’s Siaogang District (小港), Su said that sulfur dioxide emissions dropped by half from 2017 levels.
Dust levels over the Jhuoshuei River (濁水溪) were also halved compared with 2018 levels, he said.
Efforts by the Ministry of Economic Affairs and the Ministry of Transportation and Communications to encourage the public to exchange aging two-cycle engine scooters resulted in 910,000, or 60 percent, of vehicles being exchanged, Su said.
More than 3,700 low-pollution boiler units used for industrial or commercial purposes have been introduced, surpassing a target of 2,800 units, Su said.
The government in May approved the next stage of air pollution control plans, which are to be implemented from this year to 2023, with an estimated budget of NT$51.1 billion, Su said.
Government efforts are to focus on increased control over pollution sources, aided by the adoption of technology-efficient measures, he said.
Taiwanese scientists have engineered plants that can capture about 50 percent more carbon dioxide and produce more than twice as many seeds as unmodified plants, a breakthrough they hope could one day help mitigate global warming and grow more food staples such as rice. If applied to major food crops, the new system could cut carbon emissions and raise yields “without additional equipment or labor costs,” Academia Sinica researcher and lead author the study Lu Kuan-jen (呂冠箴) said. Academia Sinica president James Liao (廖俊智) said that as humans emit 9.6 billion tonnes of carbon dioxide compared with the 220 billion tonnes absorbed
The Taipei Mass Rapid Transit (MRT) Wanda-Zhonghe Line is 81.7 percent complete, with public opening targeted for the end of 2027, New Taipei City Mayor Hou You-yi (侯友宜) said today. Surrounding roads are to be open to the public by the end of next year, Hou said during an inspection of construction progress. The 9.5km line, featuring nine underground stations and one depot, is expected to connect Chiang Kai-shek Memorial Hall Station to Chukuang Station in New Taipei City’s Jhonghe District (中和). All 18 tunnels for the line are complete, while the main structures of the stations and depot are mostly finished, he
Taipei is to implement widespread road closures around Taipei 101 on Friday to make way for large crowds during the Double Ten National Day celebration, the Taipei Department of Transportation said. A four-minute fireworks display is to be launched from the skyscraper, along with a performance by 500 drones flying in formation above the nearby Nanshan A21 site, starting at 10pm. Vehicle restrictions would occur in phases, they said. From 5pm to 9pm, inner lanes of Songshou Road between Taipei City Hall and Taipei 101 are to be closed, with only the outer lanes remaining open. Between 9pm and 9:40pm, the section is
China’s plan to deploy a new hypersonic ballistic missile at a Chinese People’s Liberation Army Rocket Force (PLARF) base near Taiwan likely targets US airbases and ships in the western Pacific, but it would also present new threats to Taiwan, defense experts said. The New York Times — citing a US Department of Defense report from last year on China’s military power — on Monday reported in an article titled “The missiles threatening Taiwan” that China has stockpiled 3,500 missiles, 1.5 times more than four years earlier. Although it is unclear how many of those missiles were targeting Taiwan, the newspaper reported
