TDV: The head of United Nations climate efforts has called for an accelerated global transition to renewable energy, warning that ongoing geopolitical tensions have exposed the deep vulnerabilities of fossil fuel dependence.
Speaking during Green Transformation (GX) Week in Yeosu, the UN climate chief said the recent conflict in the Middle East has triggered a surge in fossil fuel costs, placing economies worldwide under severe strain. He noted that rising energy prices are eroding national security and sovereignty, leaving countries—and their citizens—exposed to instability.
“War has once again revealed the soaring costs of fossil fuel dependency,” he said, highlighting that Asian economies have been particularly affected. South Korea, which relies heavily on imported energy, was cited as especially vulnerable.
Referencing remarks by Lee Jae-myung, the UN official emphasized that the shift to renewable energy can no longer be delayed. He described clean energy as “the antidote to fossil fuel cost chaos,” pointing out that sources like solar and wind are not disrupted by conflict or global supply chain shocks.
The UN climate chief stressed that renewable energy offers a path for governments to regain control over their economies while enhancing national security. He urged countries to accelerate the transition without locking in further fossil fuel investments, particularly coal, even as they address short-term energy needs.
Beyond energy security, he warned that climate-related disasters—including floods, storms, and extreme heat—are already damaging economies, driving inflation, and disrupting lives and businesses worldwide. Strong climate action, he said, will be key to maintaining economic competitiveness as global demand for clean energy solutions continues to grow.
He also highlighted the economic opportunities tied to the transition, particularly for South Korea. With its advanced technology sector and skilled workforce, the country is well-positioned to benefit from what he described as a “multi-generational economic boom” driven by clean energy investments.
Through its GX strategy, South Korea is already aligning climate action with economic growth, job creation, and industrial competitiveness. The UN official praised the country’s leadership and encouraged further efforts to align public finance with energy transition goals.
GX Week, alongside UN Climate Week in Yeosu, is bringing together policymakers, business leaders, and civil society to turn climate commitments into tangible projects. The initiative aims to bridge the gap between international pledges and real-world implementation.
Concluding his remarks, the UN climate chief urged governments and industries to seize the opportunities presented by the clean energy transition, build resilient economies, and ensure long-term prosperity and security.
