I arrive at COP30 in Belém with a sense of hope. As soon as I walk into the blue zone for the first time, I realize this is not like any climate summit I have ever seen. On one side, there are pavilions from countries like Germany, Japan, and the UAE. Sleek booths lit with bright LEDs, humming with promise. Inside, they showcase AI-driven energy grids, models of Carbon Capture and Storage plants, and displays of green-hydrogen-powered buses and ships. They talk excitedly about grids that balance clean power with machine precision, about carbon-sucking machines that will clean the air, about deep-tech solutions ready for scale. It feels less like an exhibition and more like the future itself. Maybe a tech expo wrapped in a climate-action label.
I wander through those zones, trying to imagine what it would be like if such technologies existed back home. What if Bangladesh could plug into those futuristic grids? What if carbon capture plants were built across the delta? What if we had hydrogen-powered buses instead of cheap diesel? The thought flickers for a second. Then it fades, because I know the real story back home is very different.
Later, I step into a side event where delegations from climate-vulnerable countries gather. The energy drops. There are maps of rising sea levels, projections of storm surges, stories of farms swallowed by salinity, houses lost to cyclones, and rivers creeping into fertile land. The conversations are about embankments, flood defences, cyclone shelters, and saline-tolerant crops. Not carbon capture. For many here, the climate crisis is not a technology puzzle to be solved tomorrow. It is today’s survival test.
That feeling hits me hard because I come from Bangladesh. A country already reeling under floods, cyclones, river erosion, and saltwater intrusion. We are not planning for hydrogen buses or carbon-sucking factories. We are trying to keep people alive, crops to sustain, and communities safe. Scholars and climate-resilience experts have long warned that Bangladesh’s vulnerability is due to its geography, dense population, and dependence on agriculture, which is its primary concern.
I think about how climate adaptation in Bangladesh often means building embankments, strengthening coastal communities, investing in flood-resistant farming, and improving early-warning systems. Small, incremental tools of survival rather than dramatic mitigation inventions.
Walking between the glossy pavilions and the sober meeting rooms, the contrast feels like a divide not just of wealth, but of hope. Here, the rich world treats climate change as a challenge to solve. Many countries treat it as a catastrophe to endure. The gleaming prototypes across the aisle feel almost like symbols of how far apart these worlds are.
I met a delegate from a low-lying delta country. She talks about losing farmland, entire villages shifting inland, and increasing salinity in drinking water. She says, “We don’t ask for carbon machines. We ask for help to survive. Not to decarbonize, but just to stay alive.” Her voice catches. I realize that for many, COP is not about innovation; it is about pleading for survival tools.
Yet just a few pavilions earlier, I saw people discussing satellite technology to monitor emissions, robotics to reforest entire regions, and automated systems to predict and prevent environmental damage. The energy and money behind those plans seemed enormous. I could not help but wonder, why are these not shared more equitably?
Because here lies a harsh truth. Mitigation technologies, deep-tech climate tools, and carbon-removal infrastructure, many of them remain locked behind expensive patents, massive capital investments, and industrial supply chains tuned for developed countries. Rich nations have the resources for Research and Development (R&D), manufacturing, and deployment. Poorer ones, especially climate-vulnerable countries, seldom get to use them, even though they often need them most.
At COP30 this year, as negotiations unfolded, many vulnerable countries, including Bangladesh, emphasised adaptation and finance rather than emission-cutting technology.
Standing there, I felt the gap between the world of shiny prototypes and the world of saltwater flooding, disappearing livelihood, and dying crops. The technology divide felt like a barrier between “those who can fight climate change” and “those who must survive it.”
And I understood why many people call it climate injustice. Because those least responsible for causing emissions often bear the worst brunt and get the weakest tools to respond. The difference is not ambition or will; it is access.
As I left the final plenary, I remembered a line from one of the closing sessions: yes, global cooperation is alive, the summit ended with some promises. But walking through those pavilions made me realize, cooperation means little if it doesn’t close gaps between survival and innovation, between adaptation and mitigation, between the world that builds the future, and the world that struggles to stay afloat.
COP30 shows two faces of climate change. One is hopeful, technological, and forward-looking. The other one is urgent, fragile, and rooted in survival. And unless true mechanisms emerge for sharing technology, finance, and equity won’t mean much for people like those I met living on deltas, rivers, salinity, storms, and uncertainty.
Leaving Brazil, I carried with me a simple thought. For many, climate justice will not come from carbon removal machines. It will come the day when those machines or the funds for them become available not just in expos, but in vulnerable communities.
