President Prabowo Subianto's recent address at the United Nations touched on a range of issues, but among other things it carried an important pledge: Indonesia’s commitment to achieving net-zero carbon emission by 2060, or even earlier. It is a remarkably ambitious climate commitment, particularly from a populist leader from the Global South where economic development often takes precedence over climate mitigation. The pledge is all the more striking given that, just before Prabowo’s speech, U.S. President Donald Trump dismissed the climate crisis as mere fantasy. Both men are populist leaders, yet their positions on the issue of climate crisis could not be more sharply opposed.
Strikingly, it is no longer the leader of the Global North who offers the more reasonable view. After hearing both leaders’ speeches, some observers might reasonably conclude that climate leadership today is more likely to come from Jakarta than from Washington.
What explains this unexpected contrast?
Let us begin by considering Indonesia’s position as a rising middle-power seeking greater legitimacy on the global stage. For Jakarta, demonstrating attentiveness to key international concerns is a way of reinforcing its claim to a more prominent place among nations. The decision to include a climate commitment in its UN address reflects not only the global salience of the issue, but also an understanding that climate leadership can advance Indonesia’s broader diplomatic aspirations.
More importantly, Jakarta must reassure the international community that, despite the domestic struggles surrounding climate policy, its long-term commitment remains intact. Indonesia’s declared net-zero ambition stands in tension with persistent gaps, particularly in the energy sector. The most telling example is the failure to meet its initial pledge of raising the share of renewable energy to 23 percent by 2025, a target that has since been revised.
These domestic shortcomings make it all the more necessary for Jakarta to project a firm outward commitment, so as not to be perceived as faltering and thereby risk its international standing. In today’s geopolitical context, climate pledges are more than environmental targets. They function as signals of credibility and responsibility in the world stage.
For developing countries like Indonesia, climate pledges are closely linked to the prospect of attracting investment. A 2022 estimate by Indonesia’s Ministry of Energy and Mineral Resources (ESDM) projected that Indonesia would require around USD 1 trillion in renewable energy investment to achieve its 2060 net-zero target. An expert from the Institute for Essential Services Reforms (IESR) suggested that this financial requirement translates into climate-aligned financing on the order of USD 30 to 40 billion annually over the next three decades.
For Jakarta, projecting firm commitment abroad is thus not only about maintaining credibility, but also about fostering the trust and partnership necessary to mobilize financial support required for its domestic decarbonization.
While Jakarta remains attentive to its reputation and image on the global stage, Washington has largely cast both aside under the second Trump administration. Recent policies—most notably America’s recent turn toward tariffs and economic nationalism—illustrate how little priority the Trump administration places on sustaining America’s international standing. Rather than addressing a global audience, Trump’s speech appeared aimed primarily at the U.S. domestic public, where climate change has become a central fault line in the country’s political and affective polarization.
Research by political scientists Schertzer and Woods shows that Trump’s “America First” rhetoric is closely tied to a focus on reviving domestic energy production, which he frames as essential to securing America’s interests, security, and prosperity. This stands in marked contrast to the approach of Democratic leaders whose policies emphasize combating the climate crisis and accelerating a transition away from mining and other extractive industries. Republicans have generally taken a more sceptical stance on climate change, while Democrats have adopted a more activist approach. A 2022 Pew Research Center poll found that 78 percent of Democrats viewed climate change as a threat to the country’s well-being, compared with only 23 percent of Republicans. In this context, President Trump’s controversial remarks are best understood as signalling to his Republican base and reinforcing partisan ties. Washington is, in effect, consumed by its own domestic battles between polarized camps, and Trump’s speech has a domestic audience despite its global occasion.
While Washington remains preoccupied with its domestic battles, Jakarta has offered a much-needed glimpse of hope. By placing climate commitments at the center of its international messaging, Indonesia signals that emerging powers can step into roles once expected of traditional leaders. Jakarta’s more rational and globally aligned stance on the climate crisis also offers a measure of hope for activists and policymakers alike.
In an era when geopolitical power centers are shifting, it is becoming clear that reasoned leadership need not come only from the traditional metropoles of the Global North. Emerging powers of the Global South, Indonesia among them, are increasingly capable of articulating visions that resonate with global norms and expectations.
