The global shift toward clean energy has reached an economic tipping point, with annual renewable energy investment now doubling fossil fuel spending, a trend that could redefine economic competitiveness, public health, and energy security worldwide.
Speaking during a press conference in Istanbul, Executive Secretary of UN Climate Change (UNFCCC), Simon Stiell, addressed mounting concerns over the United States’ withdrawal from the Paris Agreement, the future of global climate finance, and the integrity of international climate negotiations.
His message was clear: the energy transition is no longer driven by environmental ambition alone—but by hard economic reality.
Excerpts:
What is your reaction to the United States withdrawing from the Paris Agreement and returning to coal-based energy policies?
Thank you. The first point is that the door remains open for the United States to return to both the Convention and the Paris Agreement. They have withdrawn and returned before, and that option remains available.
I will not speak to any specific country, but the science and economics are absolutely clear. Renewables are now the cheapest and cleanest form of energy production. Renewables are cheaper than coal, and the economic case is firmly established.
We are also very aware of what the science tells us about fossil fuel pollution and its impacts on lives and livelihoods globally. No country is immune to those impacts.
If countries are concerned about their economic future, public health, and long-term prosperity, the direction is clear. Investment trends reinforce this reality. Last year alone, approximately $2 trillion was invested in renewables globally, compared to about $1 trillion in fossil fuels.
This demonstrates clearly where markets are heading and where future economic opportunities lie. Many major economies have already positioned energy transition as central to their growth strategies, and this is reflected consistently in global economic data.
COP29 negotiations reportedly extended 33 hours beyond schedule. Does this make it the longest COP negotiation, and what does that signify?
I do not measure success by the number of hours negotiations take. The focus should always be on the quality and strength of the outcome.
Whether negotiations take 33 hours or less is secondary. What matters is whether the decisions reached meaningfully advance global climate action.
COP29 delivered several major outcomes. Most notably, it secured a tripling of climate finance commitments to developing countries—from $100 billion annually to $300 billion annually. While many developing countries expressed concerns about the adequacy of this level of funding, the increase itself represents significant progress.
Additionally, there was a commitment to scale climate finance further to $1.3 trillion per year, signaling recognition by developed countries of the scale of investment required.
Another critical milestone was the agreement on carbon markets under Article 6, concluding nearly a decade of negotiations. Proper implementation of carbon markets will mobilize significant financing for developing countries and support emissions reductions globally.
In that context, the additional negotiation time was necessary and worthwhile.
Does a country’s reliance on fossil fuels undermine its credibility in hosting and leading a COP?
From the UNFCCC perspective, there is no correlation between a country hosting a COP and whether it produces fossil fuels.
Recent COP hosts—including Brazil, Azerbaijan, the UAE, and Egypt—are all fossil fuel producers. Yet, these COPs delivered historic outcomes.
For example:
- COP27 in Egypt delivered the Loss and Damage Fund, ending 30 years of negotiations.
- COP28 in the UAE delivered the historic decision to transition away from fossil fuels globally.
- COP29 in Azerbaijan delivered major advances on climate finance.
- Brazil has signaled an accelerated implementation phase moving forward.
Hosting a COP is about leadership and facilitating global consensus. With Türkiye and Australia’s leadership in the coming COP process, there is every opportunity to deliver strong outcomes that address both current climate challenges and economic opportunities.
Will Afghanistan be included in COP31, given its climate vulnerability and recent exclusion from some global forums?
Registration for COP31 has not yet opened, so it is too early to comment on participation by specific countries or delegations.
