Climate change is a global problem, but its causes and consequences are not shared equally. Countries such as Nepal have contributed relatively little to the greenhouse gas emissions driving global warming. Yet they are among the countries that can face serious consequences from a changing climate, including floods, landslides, droughts, extreme rainfall, shifting water availability, and risks associated with melting glaciers. This creates an important question: Is it fair for countries that have contributed so little to climate change to bear such a significant share of its consequences? This question lies at the heart of climate justice. Climate justice recognizes that countries have contributed differently to climate change and that they also have very different financial, technological, and institutional capacities to respond to it. Countries with greater historical responsibility for greenhouse gas emissions and greater resources, therefore, have an important role to play in global climate action. But climate justice should mean more than providing financial support after a disaster has already happened. It should also involve investing in research, science, education, and technology to help prevent future damage, strengthen resilience, and reduce greenhouse gas emissions.
When a major flood destroys roads, bridges, homes, and water systems, financial assistance is clearly necessary. Communities need help rebuilding their homes and livelihoods, while governments need resources to repair damaged infrastructure. This kind of support must remain an important part of climate justice. The challenge is that climate change is not a one-time event. If the international community focuses mainly on paying for damage after disasters occur, vulnerable countries could become trapped in a repeating cycle: Disaster → Damage → Funding → Reconstruction → Another disaster. We need to ask whether some climate investment can help break that cycle rather than respond to it. The scale of the challenge is already enormous. According to the United Nations Environment Program (UNEP), developing countries may need around US$310–365 billion each year by 2035 to adapt to climate change. By comparison, international public adaptation finance to developing countries was only about US$26 billion in 2023. The gap between estimated future needs and current international public funding is therefore extremely large. This means that simply rebuilding what climate change destroys will not be enough. Countries also need the capacity to understand changing risks, prepare for them, and reduce their impacts before disasters occur.
Consider a simple example: a flood destroys a bridge. The immediate response is straightforward—help rebuild the bridge. But climate finance could do more than replace the structure that was lost. It could also support research into why flooding is becoming more severe, improve rainfall and river monitoring, strengthen early-warning systems, and help engineers design bridges that can withstand future climate conditions. In that way, climate finance would not simply replace what was lost. It would help communities become better prepared for what comes next. The same principle applies to many other climate challenges. Instead of only compensating farmers after droughts have destroyed their crops, research could help develop crops and farming practices that perform better under changing climate conditions. Instead of rebuilding settlements after floods, better forecasting and early-warning systems could give communities more time to prepare or evacuate. And instead of continually paying for the consequences of greenhouse gas emissions, investment in cleaner technologies could help reduce those emissions in the first place. This is where research and technology become an important part of climate justice.
When people hear the term "climate finance," they often think about solar panels, dams, electric vehicles, flood barriers, or other large infrastructure projects. But climate infrastructure can take many forms. A laboratory can be climate infrastructure. So can a university research center, a weather-monitoring station, or the education and training of a young scientist or engineer. For countries such as Nepal, investment in climate research could support renewable energy, hydropower, energy storage, electric transportation, low-carbon construction, sustainable agriculture, forest management, waste management, and technologies that reduce greenhouse gas emissions. Research is equally important for adapting to climate change. Nepal could benefit from stronger research into glaciers, floods, landslides, water resources, agriculture, biodiversity, and climate-resilient infrastructure. These are not simply academic subjects. They directly affect people's homes, food, water, energy, health, and livelihoods. A stronger research system can also help countries respond to their own climate challenges rather than depending entirely on knowledge and technologies developed elsewhere.
There is another important part of this discussion: who can develop and improve technology? Supporting developing countries with technology should not simply mean that wealthy countries manufacture equipment while poorer countries purchase or receive it. Countries also need the knowledge and skills to understand, operate, maintain, repair, improve, and eventually develop technologies themselves. The United Nations climate system recognizes the importance of this approach. The UNFCCC Technology Mechanism supports developing countries in accessing and using technologies that can reduce greenhouse gas emissions and strengthen resilience to climate change. Climate technologies can include renewable energy systems, drought-resistant crops, early-warning systems, and the knowledge and training required to use them effectively. This distinction matters. Giving a country a technology can help solve a particular problem. Helping that country develop the scientific and technical capacity to understand, improve, and create technologies can help address problems for generations. That is the difference between providing technology and building technological capability.
Countries that contribute relatively little to global greenhouse gas emissions should not be viewed only as victims of climate change or as recipients of climate assistance. They can also be contributors to climate solutions. Nepal has unique mountains, rivers, forests, ecosystems, and climatic conditions. Scientists working within the country are therefore in a strong position to study these environments and develop solutions that respond to local realities. Imagine stronger research centers in Nepal working on Himalayan climate change, glacier monitoring, floods and landslides, hydropower, renewable energy, greenhouse gas emissions, sustainable agriculture, and climate-resilient infrastructure. Imagine international climate programs in which Nepali researchers are not only involved as local assistants or data collectors, but also lead research projects, publish findings, develop technologies, and contribute to international scientific discussions. Such investment could leave something valuable behind long after an individual climate project ends: knowledge, laboratories, trained scientists, engineers, institutions, and technologies. That would be a much deeper form of climate support.
Supporting countries affected by climate change is essential, but adaptation and recovery cannot replace efforts to reduce greenhouse gas emissions that cause the problem. If global emissions remain high, the need for adaptation—and the cost of adaptation—will continue to grow. UNEP has emphasized that insufficient progress in reducing greenhouse gas emissions contributes to increasing adaptation needs and costs. Climate justice, therefore, needs to work in both directions. Countries and economies with high levels of emissions need to continue reducing their own emissions, while international cooperation can help developing countries move toward cleaner forms of development. Research has an important role to play in this transition. The world still needs better and more affordable renewable energy systems, improved batteries and energy storage, cleaner industrial processes, low-carbon construction materials, better public transportation, methane-reduction technologies, and many other solutions. The benefits of these technologies should not remain limited to countries that can afford large and expensive research programs. International cooperation should help make climate technologies more accessible to developing countries while also strengthening their capacity to participate in developing them. The international climate system increasingly recognizes this need. Under the UN climate process, the Technology Mechanism was established to accelerate the development and transfer of climate technologies, particularly for developing countries. More recently, the Belém Technology Implementation Program, adopted at COP30, placed additional emphasis on supporting the technology priorities identified by developing countries.
We need to rethink what successful climate finance should look like. After a climate disaster, we often ask: How much money was provided? That is an important question, but it should not be the only one. We should also ask:
If the answer to some of these questions is yes, then climate finance has achieved more than short-term recovery. It has helped build climate capability. This kind of investment can make countries better able to understand their own climate risks, develop their own solutions, and participate more meaningfully in global climate action.
Climate justice must continue to provide financial support to communities and countries experiencing climate-related losses. People who lose their homes, livelihoods, roads, and infrastructure cannot simply be told to wait for future technologies or research. Compensation and recovery, therefore, remain essential. But compensation alone is not enough. A fair climate response needs to operate on several fronts at the same time: helping communities recover from unavoidable losses, helping vulnerable countries prepare for future climate impacts, reducing greenhouse gas emissions, and investing in the research and technologies needed to develop better solutions. For countries such as Nepal, this means climate funding should not arrive only after a road has collapsed, a flood has destroyed a settlement, or a landslide has damaged infrastructure. Some of that investment should arrive before the disaster in universities, laboratories, monitoring systems, research institutions, scientists, engineers, innovation centers, and new technologies. Climate justice should not simply help vulnerable countries survive the consequences of climate change. It should help give them the scientific and technological capacity to shape their own future and contribute to solving the global climate challenge. In the end, perhaps the goal should be to move from climate aid to climate capability: from rebuilding what has been lost to building the knowledge, institutions, people, and technologies needed to make future losses less likely. That is not only an investment in developing countries. It is an investment in a more capable and resilient global response to climate change.
