Last month, the UN confirmed that the world has failed to contain global warming to the Paris Agreement’s threshold of 1.5°C, sounding a death knell for global climate governance. This is no longer a future warning, but an immediate reality.
Humankind is facing a crossroads of existential consequence, and yet US President Donald Trump is instead pushing to expand fossil fuel policy and refused to send an official delegation to this year’s COP30 climate summit. The world’s largest economy and historical emitter, it seems, is stepping back from the fight.
These climate and political shocks come as dual blows to Taiwan, which is on the front line of the climate crisis and highly reliant on international trade. Alarm bells are ringing not just for the environment, but over national security and economic survival.
The destructive consequences of the Trump administration’s decisions are not just about US carbon emissions, but about their political reverberations. Institutions of global governance do not come easy, and the US’ absence has served to seriously undermine the Paris Agreement.
Against a backdrop of warming set to exceed the 1.5°C threshold, world leaders gathered at COP30 to discuss emergency response measures to “loss and damage.” The lack of US presence sends a clear signal that “America first” and barefaced energy nationalism are prioritized above any principle of shared global responsibility.
There is a danger of major developing countries holding up US inaction as an excuse to delay their own decarbonization, and that the undercutting of global climate finance commitments would push vulnerable nations in need of adaptation funding into further precarity. The cooling effect of the US breaking ranks on international cooperation is unmistakable.
In Taiwan, we cannot afford to view the crisis as the business of other countries. A breach of 1.5°C of warming constitutes a direct and immediate threat to Taiwan’s survival. Powerful typhoons and floods are set to become a regular occurrence, while high temperatures and extreme dry periods threaten key sectors, including agriculture and the semiconductor industry, which require stable supplies of electricity and water.
The UN’s admission of failure means that it is time for Taiwan to take its plans for domestic adaptation and building resilience to a wartime level of urgency. There is no time for empty talk about net zero by 2050 — we must confront the imminent climate shocks now.
As our most important political ally, the US’ choice to step back and embrace fossil fuels would inevitably embolden domestic voices calling to slow down emission reductions to protect the economy. Going down this road would only further isolate Taiwan economically. The US might have abandoned the fight, but the EU stands ready and waiting as the world’s largest single market, armed with its Carbon Border Adjustment Mechanism (CBAM) as an economic goad. Being an export-oriented country, Taiwan’s key industries of steel, petrochemicals and electronic components tie it to the EU’s green supply chain.
If Taiwan chooses to follow the US’ lead, it can expect to face high EU carbon taxes and exclusion from the supply chains of international brands like Apple and Microsoft, which are bound by environmental, social, and governance commitments. These economic ramifications are too great for Taiwan to ignore.
Facing climate breakdown and the crumbling of political leadership, Taiwan’s response must be focused and determined. We cannot allow for distractions or wishful thinking, and we must recognize that a net zero transition is no longer just an environmental issue, but one of economic survival and national security.
First, the government must resist internal pressure and accelerate its deployment of renewable energy, in particular in geothermal, biomass and energy storage systems to ensure a stable transition.
Second is to transform and upgrade industry — the government must shift from across-the-board subsidies to mandatory transitional guidance for carbon-intensive industries to adopt new technologies and comply with CBAM standards.
Finally, climate resilience must become a core principle of all public development projects. From the urban “sponge city” concept to disaster-warning systems in rural areas, public infrastructure and engineering projects must be reimagined to fully reflect the reality of a world having broken the 1.5°C threshold.
The US’ move is a gamble that Taiwan cannot afford to make. This moment of global disorder is exactly the point at which Taiwan must demonstrate its resilience and ability to turn the crisis into an opportunity for transformational change.

The Chinese Communist Party (CCP) has long been expansionist and contemptuous of international law. Under Chinese President Xi Jinping (習近平), the CCP regime has become more despotic, coercive and punitive. As part of its strategy to annex Taiwan, Beijing has sought to erase the island democracy’s international identity by bribing countries to sever diplomatic ties with Taipei. One by one, China has peeled away Taiwan’s remaining diplomatic partners, leaving just 12 countries (mostly small developing states) and the Vatican recognizing Taiwan as a sovereign nation. Taiwan’s formal international space has shrunk dramatically. Yet even as Beijing has scored diplomatic successes, its overreach
After 37 US lawmakers wrote to express concern over legislators’ stalling of critical budgets, Legislative Speaker Han Kuo-yu (韓國瑜) pledged to make the Executive Yuan’s proposed NT$1.25 trillion (US$39.7 billion) special defense budget a top priority for legislative review. On Tuesday, it was finally listed on the legislator’s plenary agenda for Friday next week. The special defense budget was proposed by President William Lai’s (賴清德) administration in November last year to enhance the nation’s defense capabilities against external threats from China. However, the legislature, dominated by the opposition Chinese Nationalist Party (KMT) and Taiwan People’s Party (TPP), repeatedly blocked its review. The
In her article in Foreign Affairs, “A Perfect Storm for Taiwan in 2026?,” Yun Sun (孫韻), director of the China program at the Stimson Center in Washington, said that the US has grown indifferent to Taiwan, contending that, since it has long been the fear of US intervention — and the Chinese People’s Liberation Army’s (PLA) inability to prevail against US forces — that has deterred China from using force against Taiwan, this perceived indifference from the US could lead China to conclude that a window of opportunity for a Taiwan invasion has opened this year. Most notably, she observes that
The Chinese Nationalist Party (KMT) said on Monday that it would be announcing its mayoral nominees for New Taipei City, Yilan County and Chiayi City on March 11, after which it would begin talks with the Taiwan People’s Party (TPP) to field joint opposition candidates. The KMT would likely support Deputy Taipei Mayor Lee Shu-chuan (李四川) as its candidate for New Taipei City. The TPP is fielding its chairman, Huang Kuo-chang (黃國昌), for New Taipei City mayor, after Huang had officially announced his candidacy in December last year. Speaking in a radio program, Huang was asked whether he would join Lee’s
