Assessing reskilling programs to manage the European green transition
This study demonstrates that individually tailored reskilling programs, which leverage workers' existing transferable skills, are significantly more effective than standardized green or digital training in managing Europe's labor market transition, ultimately reducing aggregate income losses and highlighting the need for region-specific policies rather than funding based solely on the number of at-risk jobs.

The European economy is undergoing a profound transformation as it shifts away from fossil fuels toward cleaner energy sources. This transition, often called decarbonization, is not just about building wind turbines or installing solar panels; it is fundamentally about people. As industries that rely on coal, oil, and gas shrink, the workers who power them face a difficult future. Simultaneously, the new green economy is growing, but it often lacks the skilled workers needed to fill its expanding roles. The central challenge for policymakers is not simply to build new infrastructure, but to ensure that the human workforce can move from the jobs that are disappearing to the jobs that are emerging. This requires a clear understanding of how workers can learn new abilities, a process known as reskilling, and which types of training actually open doors to new careers.
For decades, the assumption has been that specific new skills, particularly those labeled as "green" or "digital," are the golden ticket for workers in declining industries. The logic seemed sound: if a job is lost because of pollution, learning to fix pollution should be the solution. If a job is lost because of automation, learning to code should be the answer. However, a new study from researchers at the Technical University of Munich challenges this straightforward thinking. By simulating the learning journeys of thousands of workers across ten European countries, the team discovered that the most effective way to reskill depends entirely on where a worker is starting and where they are trying to go. There is no single, universal training program that works for everyone, and the popular focus on teaching green or digital skills in isolation may actually be the least efficient path for many.
The researchers built a detailed computer simulation to map out these potential career shifts. They used real data on the skills required for thousands of different occupations and matched them with the actual workforce in Europe. In their model, they tested four distinct approaches to training. The first three were standardized programs where every worker learned the same set of skills: a program focused purely on transferable skills like communication and management, a program focused on green skills like pollution prevention, and a program focused on digital skills like coding. The fourth approach was different; it was tailored. Instead of giving everyone the same list, this program looked at what a specific worker already knew and taught them the specific new skills that would best complement their existing abilities, effectively building a bridge from their current reality to a new job.
The simulations revealed a striking difference in how these programs performed depending on the direction of the move. For workers leaving jobs that are at risk of disappearing, such as diesel mechanics or coal plant operators, the tailored approach was by far the most effective. These workers could unlock a new job option after learning just four new, specific skills that fit their existing profile. In contrast, if these same workers followed a standardized program focused on transferable skills, they would need to learn about thirteen new skills before they could access a single new job. The green and digital programs performed even worse for this group; in many cases, workers learned a significant number of skills but still found themselves unable to qualify for a new role because those specific skills did not overlap enough with the requirements of other jobs.
However, the story flipped when the researchers looked at workers trying to move into low-carbon jobs, such as wind turbine technicians. For these workers, the goal was to enter a specialized field that requires a broad and complex set of abilities. Here, the tailored approach was inefficient, requiring workers to learn up to twenty-six new skills to find a match. The standardized transferable skills program, which focused on general abilities used across many industries, was the most effective route, allowing workers to reach a low-carbon job after learning about seventeen skills. This suggests that while customizing training helps people leave dying industries quickly, the broad, general skills are what actually get people into the new, specialized green economy.
The study also highlighted the financial reality of these transitions. When workers in at-risk jobs switched to new roles using the tailored approach, they faced an initial income loss of about twenty percent. This is a significant drop, but the simulations showed that as they continued to learn more skills, their earnings eventually recovered to their previous levels. Interestingly, the transferable skills program, while taking longer to complete, eventually led to even higher potential earnings, with some workers seeing gains of up to fifty percent after learning twenty skills. The researchers noted that while the tailored path gets workers to a new job faster, the transferable path might offer a better long-term financial ceiling, provided the worker can endure the longer training period and the initial pay cut.
Perhaps the most surprising finding was that the difficulty of reskilling does not match the number of jobs at risk in a region. One might assume that areas with the most coal mines or factories would be the hardest to transition. The data showed this was not the case. Some regions with a high number of at-risk jobs, such as parts of Poland and the Czech Republic, actually had relatively easy paths for workers to reskill because the local labor market offered many accessible alternatives. Conversely, some regions with fewer at-risk jobs, like parts of Spain and Greece, faced much greater difficulty in finding new roles for their workers. This means that funding based solely on the number of jobs lost could be misdirected, pouring money into regions that do not need it as urgently while missing the areas where the skills gap is truly insurmountable.
The researchers concluded that the current policy trend of heavily emphasizing green and digital skills in isolation may not align with the simulation results. Their simulations showed that these narrow programs often fail to open up new job options for workers in declining industries. Instead, effective policy needs to be flexible. For workers leaving high-carbon industries, programs should be tailored to build on what they already know, helping them make a quick, manageable leap to a new career. For those aiming to fill the new green economy roles, broad, transferable training is more valuable. The study suggests that a one-size-fits-all approach will not work; the path forward requires matching the training to the specific journey of the worker and the unique conditions of their local labor market. Without this nuance, the green transition risks leaving behind the very people it needs to succeed.
