Experts today urged the government to establish a platform that integrates climate-related data to address fragmented tools used to measure climate change.
The government should not wait until the carbon fee is collected next year, as it would then be too late, they told a news conference held by the Taiwan Science and Technology Media Center ahead of the UN Climate Change Conference (COP30) this month.
COP30, which is to be held in Brazil starting on Monday next week, is expected to discuss nationally determined contribution (NDC) targets, including emission reduction targets for 2035.

The summit is also expected to address significant funding gaps for developing countries in climate adaptation and explore practical mechanisms.
Brazil has proposed initiatives such as a "global common carbon market" and a "Tropical Forest Forever Facility."
As US President Donald Trump’s administration reduced subsidies and investment in green technology and cut international green funding commitments, it may have a negative short-term impact on momentum, Taiwan Research Institute Research Division IX director Yen Wan-ting (顏婉庭) said.
However, the long-term trend remains positive, as major economies like the EU, Japan and South Korea maintain net-zero ambitions, with many market mechanisms and standards already in place, she said.
Regarding Taiwan’s emissions goals, Taiwan Climate Action Network Research Center director Chao Chia-wei (趙家緯) said the government has proposed reducing carbon emissions by 36 percent to 40 percent by 2035 relative to the 2005 baseline and presented a draft NDC in September.
However, according to scenario analysis, even with a 38 or 40 percent reduction by 2035, the nation would only achieve about an 80 percent reduction level by 2050, falling short of the statutory 2050 net zero goal, Chao said.
Regarding adaptation efforts, Tung Ching-pin (童慶斌), a professor at National Taiwan University's Department of Bioenvironmental Systems Engineering, said the government should immediately invest in integrating information and adaptation technologies rather than wait for next year’s carbon fee revenues to start planning.
The nation’s existing climate decision support tools are fragmented, with areas such as the water, energy, transportation and health sectors operating independently, he said.
Interfaces and data are difficult to integrate, hindering systemic cross-sectoral risk assessment, he said.
Citing railway construction as an example, he said that adaptation efforts involve assessing risks such as high temperatures, slope collapse and flooding.
These data currently belong to three different agencies and vary in format, making integration difficult, he said.
The government needs to transform existing scientific data into effective adaptation strategies by building an information platform that would allow railway authorities to directly use integrated data to assess vulnerabilities, without having to handle core climate data themselves, he said.
A magnitude 6.1 earthquake struck off the coast of Yilan County at 8:39pm tonight, the Central Weather Administration (CWA) said, with no immediate reports of damage or injuries. The epicenter was 38.7km east-northeast of Yilan County Hall at a focal depth of 98.3km, the CWA’s Seismological Center said. The quake’s maximum intensity, which gauges the actual physical effect of a seismic event, was a level 4 on Taiwan’s 7-tier intensity scale, the center said. That intensity level was recorded in Yilan County’s Nanao Township (南澳), Hsinchu County’s Guansi Township (關西), Nantou County’s Hehuanshan (合歡山) and Hualien County’s Yanliao (鹽寮). An intensity of 3 was
Instead of focusing solely on the threat of a full-scale military invasion, the US and its allies must prepare for a potential Chinese “quarantine” of Taiwan enforced through customs inspections, Stanford University Hoover fellow Eyck Freymann said in a Foreign Affairs article published on Wednesday. China could use various “gray zone” tactics in “reconfiguring the regional and ultimately the global economic order without a war,” said Freymann, who is also a nonresident research fellow at the US Naval War College. China might seize control of Taiwan’s links to the outside world by requiring all flights and ships entering or leaving Taiwan
Taiwan's first indigenous defense submarine, the SS-711 Hai Kun (海鯤, or Narwhal), departed for its 13th sea trial at 7am today, marking its seventh submerged test, with delivery to the navy scheduled for July. The outing also marked its first sea deployment since President William Lai (賴清德) boarded the submarine for an inspection on March 19, drawing a crowd of military enthusiasts who gathered to show support. The submarine this morning departed port accompanied by CSBC Corp’s Endeavor Manta (奮進魔鬼魚號) uncrewed surface vessel and a navy M109 assault boat. Amid public interest in key milestones such as torpedo-launching operations and overnight submerged trials,
The next minimum wage hike is expected to exceed NT$30,000, President William Lai (賴清德) said yesterday during an award ceremony honoring “model workers,” including migrant workers, at the Presidential Office ahead of Workers’ Day today. Lai said he wished to thank the awardees on behalf of the nation and extend his most sincere respect for their hard work, on which Taiwan’s prosperity has been built. Lai specifically thanked 10 migrant workers selected for the award, saying that although they left their home countries to further their own goals, their efforts have benefited Taiwan as well. The nation’s industrial sector and small businesses lay
