The Ministry of Environment is to establish an alliance to propose heat response plans by the end of next month amid global climate change.
High temperatures are the most tangible signs of climate change for the public, and to help people adapt to a warmer environment, the ministry is setting up the High Temperature Response Alliance, Climate Change Administration Deputy Director-General Hsu Hsu-cheng (徐旭誠) said on Saturday.
The effort would be focused on protecting high-risk groups, such as agricultural workers and others who work outdoors, from heat hazards, he said.

The ministry would also collaborate with local governments to create “cool maps” of comfortable outdoor activity sites for the public and would help shape a heat-response industrial chain, he said.
More than 70 percent of the heat transferred into buildings in Taiwan results from solar heat passing through glass doors or windows, while only about 20 percent is conducted through walls, National Cheng Kung University architecture professor Lin Tzu-ping (林子平) said.
Therefore, installing outdoor sun-shading structures is the most effective method to prevent solar heat from entering buildings, Lin said.
Indoor heat-blocking measures would be the second-best approach, such as using window blinds or covering glass doors or windows with thermal insulation film, he said.
Regarding electricity use, residential and commercial properties accounted for about 22 percent of total power consumption, he said.
While newly constructed buildings are required to meet energy efficiency standards, Taiwan lacks an effective energy-saving scheme for existing buildings, Lin said.
The Ministry of the Interior should follow the example of the Netherlands and mandate the disclosure of buildings’ energy efficiency ratings in profiles of housing for rent or sale, he said.
“Just as we would consider fuel consumption when buying a vehicle, we should also consider a building’s power consumption before renting or buying it,” Lin said, adding that tax deductions or other incentives could encourage landlords or building owners to disclose energy efficiency ratings.
Boosting buildings’ heat-blocking efficacy to reduce indoor temperatures can reduce power consumption and carbon emissions, Department of Comprehensive Planning Director Hung Shu-sing (洪淑幸) said.
While the Ministry of the Interior and the Ministry of Economic Affairs are responsible for promoting building energy conservation for the residential and commercial sector, the enviro`nment ministry would plan budgets to subsidize heat insulation projects for existing housing, Hung said.
The replacement of traditional windows with heat-blocking units and the enhancement of roof heat insulation at schools would be prioritized, with subsidy details to be discussed, she added.
Eight Chinese naval vessels and 24 military aircraft were detected crossing the median line of the Taiwan Strait between 6am yesterday and 6am today, the Ministry of National Defense said this morning. The aircraft entered Taiwan’s northern, central, southwestern and eastern air defense identification zones, the ministry said. The armed forces responded with mission aircraft, naval vessels and shore-based missile systems to closely monitor the situation, it added. Eight naval vessels, one official ship and 36 aircraft sorties were spotted in total, the ministry said.
INCREASED CAPACITY: The flights on Mondays, Wednesdays, Fridays and Sundays would leave Singapore in the morning and Taipei in the afternoon Singapore Airlines is adding four supplementary flights to Taipei per week until May to meet increased tourist and business travel demand, the carrier said on Friday. The addition would raise the number of weekly flights it operates to Taipei to 18, Singapore Airlines Taiwan general manager Timothy Ouyang (歐陽漢源) said. The airline has recorded a steady rise in tourist and business travel to and from Taipei, and aims to provide more flexible travel arrangements for passengers, said Ouyang, who assumed the post in July last year. From now until Saturday next week, four additional flights would depart from Singapore on Monday, Wednesday, Friday
The Ministry of National Defense yesterday reported the return of large-scale Chinese air force activities after their unexplained absence for more than two weeks, which had prompted speculation regarding Beijing’s motives. China usually sends fighter jets, drones and other military aircraft around the nation on a daily basis. Interruptions to such routine are generally caused by bad weather. The Ministry of National Defense said it had detected 26 Chinese military aircraft in the Taiwan Strait over the previous 24 hours. It last reported that many aircraft on Feb. 25, when it spotted 30 aircraft, saying Beijing was carrying out another “joint combat
The Ministry of Foreign Affairs (MOFA) today said that if South Korea does not reply appropriately to its request to correct Taiwan’s name on its e-Arrival card system before March 31, it would take corresponding measures to alter how South Korea is labeled on the online Taiwan Arrival Card system. South Korea’s e-Arrival card system lists Taiwan as “China (Taiwan)” in the “point of departure” and “next destination” fields. The ministry said that it changed the nationality for South Koreans on Taiwan’s Alien Resident Certificates from “Korea” to “South Korea” on March 1, in a gesture of goodwill and based on the
