A Quantitative Assessment Of Investment Environments And Risk Mitigation Strategies For Clean Energy Investments in Emerging Markets and Developing Economies
This study employs a quantitative approach to analyze how macroeconomic, political, and governance risks in emerging markets and developing economies hinder clean energy investment, demonstrating that customized, multi-instrument risk mitigation strategies which leverage non-linear interactions among risk factors can significantly improve financing outcomes.

The world is shifting its energy sources, moving away from burning fossil fuels toward wind, sun, and other clean technologies. This transition requires massive amounts of money to build the necessary infrastructure. While wealthy nations have largely solved the problem of funding these projects, a different challenge blocks progress in emerging markets and developing economies. In these regions, the potential for clean energy is huge, but the money does not flow in. The reason is not a lack of profitable projects, but a perception of risk. Investors worry about unstable currencies, fluctuating interest rates, political unrest, or weak government institutions. When these fears combine, they create a barrier that makes projects seem too dangerous to fund, or so expensive to finance that they become impossible to build.
For decades, experts have tried to fix this by looking at risks one by one. They might suggest a tool to protect against currency changes, or another to guard against political instability. However, this approach often misses the bigger picture. Risks in the real world do not exist in isolation; they interact with each other in complex ways. A problem with interest rates might become manageable if the currency is stable, but disastrous if the currency is also volatile. Understanding how these different dangers mix together is the key to unlocking the capital needed for a sustainable future.
A team of researchers at University College London has taken a fresh, data-driven look at this problem. Instead of guessing which risks matter most, they built a detailed map of the global investment landscape using historical data from thousands of clean energy projects. They wanted to see exactly how different combinations of risks influence the willingness of investors to put their money into a country. By analyzing patterns from 2010 to 2018, they discovered that the relationship between risk and investment is not a simple straight line. Instead, it is a complex web where small changes in one area can trigger huge shifts in investment potential, but only if the other risks are managed correctly.
The researchers created what they call an "investment space," a conceptual map that plots every country based on its specific mix of eight major risks. These risks include the stability of the local currency, the cost of borrowing money, the health of the economy, the creditworthiness of the government, the reliability of the power buyer, political stability, the quality of laws and regulations, and the strength of renewable energy policies. By feeding real investment data into advanced computer models, they could see which combinations of these factors led to successful projects and which led to silence from investors.
The results confirmed that wealthy nations with stable institutions are naturally the most attractive places for investment. However, the study revealed something more surprising about the developing world. The map showed that investment suitability is not determined by a single "bad" factor, but by how those factors balance each other out. For instance, a country with high political risk might still attract money if its currency is stable and its interest rates are low. But if that same country has high political risk and a volatile currency, the investment probability drops to near zero. The researchers found that these interactions create "tipping points." Once a certain threshold of risk is crossed, the investment environment collapses, but if risks are reduced even slightly below that threshold, the environment can suddenly become viable.
One of the most important findings is that fixing risks one at a time is often inefficient. The study showed that the biggest gains come from tackling specific pairs of risks together. For example, in countries like Brazil, reducing the risk of currency fluctuations alone helped a little, and reducing interest rate risks alone helped a little. But when the researchers simulated reducing both of these risks at the same time, the improvement in investment potential was far greater than the sum of the two parts. This happens because the two risks amplify each other; when both are high, they create a fear that is much worse than the individual parts. By addressing them together, the fear is dismantled much more effectively.
The study also highlighted that different countries need different solutions. There is no single "magic bullet" that works for every nation. In some places, the main barrier is the cost of borrowing money; in others, it is the fear that the government might change its mind on energy policies. The researchers used their model to trace the most efficient path for specific countries to improve their investment scores. For a country like Mali, for instance, the model showed that while its currency was already stable, its investment potential was held back by high political and institutional risks. The most effective path forward was not to try to fix everything at once, but to focus on lowering those specific political and institutional risks, which would then allow other positive factors to shine through.
The researchers tested various combinations of risk-reduction tools, such as insurance against currency loss or guarantees for loan repayments. They found that a mix of tools is almost always better than a single tool. When international institutions or governments deploy a package of measures that targets the specific, interacting risks of a country, the result is a dramatic increase in the likelihood of investment. The study suggests that the most effective strategies are those that exploit these non-linear interactions. If a country can lower its interest rate risk while simultaneously lowering its foreign exchange risk, the investment community responds with a level of confidence that neither reduction could achieve alone.
This work changes the way we think about financing the clean energy transition. It moves the conversation away from simply listing the problems a country faces and toward understanding the specific recipe of risks that keeps investors away. The study suggests that by using data to identify the exact combinations of risks that matter most in each location, policymakers and financial institutions can design targeted solutions. These solutions do not need to be perfect or eliminate all risk; they just need to be precise enough to push the investment environment across the tipping point from "too dangerous" to "worth the gamble."
The implications are significant for the future of global climate action. The researchers estimate that emerging markets and developing economies need trillions of dollars in investment by 2030 to meet their energy and climate goals. Currently, the high cost of capital in these regions, driven by perceived risk, makes many projects unviable. By understanding the complex dance of interacting risks, the world can finally start to unlock the private capital needed to build the clean energy systems of tomorrow. The path forward is not about finding a single fix, but about carefully calibrating a set of tools that work together to turn a risky investment into a safe one.
