NEW YORK — Albanese outlined Australia's domestic and international initiatives, including a government target to reduce emissions by 62-70% on 2005 levels by 2035. He noted that more than half a million home batteries were installed in Australia in the past year.

Australians are installing ten thousand home batteries each week, according to government energy data. Albanese used these figures to illustrate the economic viability of clean energy transitions.

The Prime Minister stated that scientific forecasts regarding intense weather events have come to be. "Global weather has always been treacherous. But the science told us unmistakably that as the world warms these events will become more frequent and intense. And those scientific forecasts have come to be," Albanese said.

He called for collective action to address the scale of responsibility facing global leaders. "We need to come together, to meet the problem head on. There’s no avoiding the scale of our responsibility – or the cost of inaction," he added.

On the international front, Albanese discussed the Australian government’s REnew Pacific Program, which supports climate resilient classrooms in Vanuatu and Fiji. The program also supports clean energy and water projects on one of Kiribati’s most remote islands.

The Australian government contributed A$100m towards the Pacific Resilience Facility to support these efforts. Albanese claimed the REnew Pacific Program has directly improved 300,000 lives through these initiatives.

Kristrún Frostadóttir, the Prime Minister of Iceland, gave the closing remarks at Climate Week. She described how her nation transitioned away from imported oil for heating in the early 1970s by building a large-scale geothermal district heating system in Reykjavík within a few years.

Today, nearly every home in Iceland is heated with renewable energy, with more than 90% of home heating energy coming from geothermal sources. Frostadóttir attributed this success to unwavering political support and financial mechanisms that helped households switch without ruinous upfront costs.

"Household budgets were hit and a small island nation, far from every market, every supplier, learned the hard way to depend on something you cannot control. So we made a choice. Instead of riding out the volatility, we turned to what was right under our feet, Frostadóttir said."

She emphasized the need for proactive measures before crises occur. The only real question left for leaders, for all of us in this room, is what it takes to keep moving forward faster than the disruptions that have yet to hit us. Our answer, from a small island in the North Atlantic is this: start before you must. Build the resilience before the crisis tests it, she said.

Frostadóttir noted that this transition required across party consensus that outlasted several governments. This took unwavering political support. Financial support mechanisms that helped ordinary households make the switch without ruinous upfront costs. And, perhaps rarest of all in today’s world, across party consensus that outlasted several governments," she added."

Why It Matters

Climate Week has been held annually in New York since 2009, and organizers stated that this year’s event will have more than 100,000 attendees. The gathering demonstrates the growing integration of climate action into national security, economic planning, and international aid, as demonstrated by the contributions from Australia and Iceland.

The event presents the tension between accelerating climate impacts and the political responses required to address them. With global renewable capacity reaching record levels in 2025, leaders emphasized the need to align financial and political systems with the pace of technological change and environmental necessity.

Mohamed Adow noted that renewable energy is booming but climate impacts are accelerating faster than political and financial systems are responding. Simon Stiell stated that climate change is driving up food prices and wider inflation, with billions realizing fossil fuel dependence is hitting them hard at the fuel pump. He said "the global community cannot afford to be frozen in time while the world warms around us." Simon Stiell said: "Climate change is driving up food prices and wider inflation.
