Chornobyl set a civic movement in motion — and laid the foundation for environmental engagement in Ukraine that continues to this day. The memory makes clear: the consequences of potential damage to nuclear facilities in wartime are real, not abstract.
"The fate of Ukraine was decided by the Chornobyl disaster. Because after it, Ukrainian society began to shake off the decades-long fear that had frozen the nation. We stopped being afraid."
– Oksana Zabuzhko, Ukrainian novelist, poet, and philosopher
The tragedy of Chornobyl changed the world and has shaped modern Ukrainian history. Hundreds of thousands of people were directly affected by the disaster: from liquidators (emergency responders and cleanup workers) and their families, who carry their own stories and memories; to residents of Polissia who were displaced and whose homes were abandoned, destroyed, or covered with radioactive dust; to all those who have suffered from health problems linked to the world’s largest known release of radioactivity into the natural environment.
One of the most consequential outcomes of the disaster, however, was its role in accelerating the collapse of the Soviet empire. Because Ukrainians stood up. Chornobyl sparked the birth of the Ukrainian environmental movement, which grew remarkably for late‑Soviet times into a broader civil society movement for democracy and independence.

The world often speaks today about the resilience of Ukrainians. Those who know Ukraine understand how instrumental its civil society is, and has been for decades, in sustaining that resilience. This text adds an often forgotten piece to that story, showing how the circumstances of the tragedy shaped a generation of active Ukrainian civic leaders and organisations.
Drawing on an in‑depth interview with environmental activist and Ecoaction NGO director Olexi Pasyuk, alongside historical research and contemporary observation, we ask two questions. First: What remains of Ukraine’s post‑Chornobyl environmental civil society forty years later? Second: Has Chornobyl fundamentally reshaped how Ukrainians perceive nuclear risk during the current war? To address both, we follow the arc of developments after Chornobyl until the present day.
1. Chornobyl’s Foundational Shock: How Concealing Truth and Environmental Fear Became a Political Agency
"The only alternative to those atomic stations is the People’s Movement of Ukraine."
– Ivan Drach, Ukrainian poet, screenwriter, and political leader, on the creation of Rukh in 1988
Chornobyl was both an ecological disaster and a political rupture. As noted in Oleksandr Zinchenko’s How Ukrainians Brought Down the Empire of Evil, the nuclear catastrophe triggered a chain reaction of public sentiment that overcame decades of fear. By concealing the scale of the Chornobyl disaster and even proceeding with May 1, 1986, parades instead of prioritizing public safety, the Soviet authorities eroded public trust and intensified doubts about the safety of nuclear energy. Zinchenko writes that radiation was more frightening than the KGB, and that environmental slogans soon transformed into political demands for pluralism, sovereignty, and truth. Rallies that began with “No to future Chornobyls!” evolved into the early structures of Rukh, the movement that would later propel Ukraine toward independence.
In December 1987, writer and physician Yurii Shcherbak together with his like‑minded colleagues founded Green World (Zelenyi Svit), Ukraine’s first environmental organisation, to oppose plans for construction of more nuclear plants in Ukraine. The early environmental movement, including Green World, had a unique power - it was able to criticize wider Soviet policy as long as the official justification was ecological concern. “You did not seem to be questioning the USSR,” Olexi Pasyuk notes, “but you could point out what had been done wrong.” In these cracks of permissible criticism, a democratic culture took root.
On April 26, 1988, the Ukrainian Cultural Club, the republic’s first nongovernmental organisation, staged a commemorative rally in Kyiv. Momentum crested on November 13, 1988, during the rally organised by Green World, when tens thousand people gathered near the Republican Stadium (now Olympic Stadium in Kyiv) under banners ranging from “No to new reactors” to “No to the Soviet Empire!”. The platform merged environmental, economic and other demands. Within weeks, the People’s Movement of Ukraine (Rukh) was officially launched. As Ukrainian poet Ivan Drach later reflected, “Chornobyl was the stimulus of all democratic processes in Ukraine”. Liquidators demanded justice. Dissidents and cultural figures spoke publicly. The Soviet monopoly on truth began to crumble.
Chornobyl was the stimulus of all democratic processes in Ukraine.
For many activists of the post-Chornobyl era, including Pasyuk, the disaster was personal. “We were evacuated from Kyiv in 1986. My family had thyroid problems,” he recalls. He vividly remembers not being allowed outdoors to avoid raising radioactive dust. Nevertheless, he notes that like many young Ukrainians of late 1980s to early 1990s, he initially viewed nuclear energy as a symbol of technological progress and proof that the Soviet Union possessed world‑class science. Only later, when he encountered independent information through environmental groups, did he fully understand the systemic safety failures and political manipulation that lay behind the official narrative.
2. Birth of Ukraine’s Greens, Environmental Networks and Coalitions
“Ukraine's renunciation of nuclear weapons in the 1990s was a strategic victory that saved the country from authoritarianism. Russia is a clear example of what retaining nuclear weapons does to a country with weak democracy.”
– Yevhen Hlibovytskyi, Ukrainian intellectual, member of the Nestor Group, Head of the Frontier Institute
The early environmental movement in Ukraine turned outrage over Chornobyl into a powerful civic force that delegitimized the communist regime and helped speed up the collapse of the Soviet Union. In an historic referendum in December 1991, 90 percent of Ukrainian voters supported independence. However, independence came together with a severe economic crisis and the responsibility to deal with the consequences of the Chornobyl disaster that caused billions of dollars in direct losses.
Olexi Pasyuk recalls that in the early years of independence, the government was drafting a secret decree on the establishment of a closed nuclear cycle in Ukraine with the goal to establish capacity to produce nuclear fuel independently. This would have effectively paved the way for the potential production of nuclear weapons. Implementing the idea would have been extremely difficult politically as it meant going against the backdrop of the global movement towards disarmament.
In this context, the decision that was subsequently formalized through the Budapest Memorandum seemed logical at the time: “Everyone was of the view that the trend was towards nuclear disarmament, and considering this, arming anyone did not make much sense”. At the same time, Pasyuk points out that the economic realities of the 1990s also played a role: Ukraine received free nuclear fuel from Russia for some time in exchange for renouncing its nuclear status. This helped keep the nuclear power stations operational in the midst of economic decline. Few were prepared to give up what ensured a stable electricity supply.
In these circumstances of disarmament, economic strain and continued reliance on nuclear energy, environmental activism was shifting to institution building, which opened the way for party politics and more durable civic networks.
Environmental activism shifted to institution building, which opened the way for party politics and more durable civic networks.
In 1990, the Green Party in Ukraine was formed. At the heart of its manifesto was the aim to ‘transform Ukraine into a nuclear-free zone’. The party’s first leader and Green World founder, Yurii Shcherbak, described the party’s manifesto as a response to Chornobyl and emphasized that the party had been founded on a ‘courageous determination to fight against nuclear death’. The party’s high point came in 1998: it cleared the threshold with more than 1.4 million votes, won 19 seats in the Ukrainian parliament, served a single four‑year term, but it failed to regain representation in later convocations.
In the 1990s, main campaigns of the country’s green movement were focused on two key areas: demanding permanent closure of the Chornobyl Nuclear Power Plant and avoiding construction of new nuclear reactors. While the Ukrainian leadership was discussing the closure of Chornobyl with the international community, it sought to secure new investments through asking for new energy capacities. This logic was enshrined in the 1995 memorandum of understanding between Ukraine, the EU and the G7 who promised support for the country in securing compensatory energy projects. Civil society was actively engaging with local communities, national and international stakeholders highlighting the technical risks, economic unsoundness and vulnerability of the Soviet-era project designs.
The last decade of the century marked the institutionalization of the Ukrainian environmental movement. Alongside Green World and the Green Party, new initiatives were emerging that were learning to engage with the media, parliament and international partners. The National Ecological Center of Ukraine (NECU), the Bankwatch network, Greenpeace, Ecoclub, MAMA-86 and a number of local groups managed to develop joint tactics, coordinated messages at meetings with international financial institutions and built up local branches across the country.
This collaboration had not only an organisational dimension but also an educational one. Ukrainian activists received guidance from European colleagues with many years of experience in public campaigns and working with development banks. For the fledgling Ukrainian civil society, this meant a shift from spontaneous protests to procedural advocacy: involving documents, deadlines, demands on the regulator and economic calculations.
3. After Chornobyl Shutdown: From Anti-Nuclear to Climate and Security
The formal shutdown of the Chornobyl Nuclear Power Plant in 2000 did not end the country’s confrontation with the consequences of the disaster. Neither the state nor civil society could consider the issue closed. At the same time, as Olexi Pasyuk notes, Ukrainian society largely maintained a mental boundary between the catastrophe itself and nuclear energy as a sector:
“Interest to Ukraine in connection with Chornobyl remained. Ukraine continued to demonstrate that there were significant consequences, and for many this became a tragedy. But it is important to note that there was a clear distinction between the issues of Chornobyl and nuclear energy as such.”
This distinction shaped both public discourse and state policy. For civil society organisations, the agenda shifted toward more complex technical and long‑term challenges. When it came to Chornobyl itself, there was a need to stabilize the ageing shelter structure, construct the new safe confinement, and develop infrastructure for spent fuel and radioactive waste management. These tasks required continuous oversight of engineering quality, contractor accountability, and transparency in spending, especially given the role of international funding mechanisms.
At the same time, the question of new nuclear power generation facilities was on the table. Ukraine was negotiating with the European Bank for Reconstruction and Development (EBRD) the support for completion of Khmelnitsky NPP-2 and Rivne NPP-4.
Chernobyl: 40 Years After the Disaster
40 years after the Chernobyl reactor disaster, Russia is once again jeopardizing nuclear safety in Eastern Europe with direct attacks on nuclear power plants in Ukraine. Our dossier highlights memories and current debates in selected countries.
Even though civil society organisations tried to dissuade EBRD from taking the decision on financially supporting the project, the bank was close to agreeing to provide a loan bound to a number of conditions. Suddenly, President Leonid Kuchma announced that the loan from EBRD was not needed, citing excessive demands from the bank. As Pasyuk recalls, the real reason was Russia’s promise to provide support and equipment for the construction. As a result, the units were commissioned in 2004 using domestic financial resources.
Amid these developments, the anti-nuclear movement in its early, mass-based form was disappearing and changing. Environmental organisations continued to raise the issue of nuclear power, but without the scale of mobilization seen in the 1980s and 1990s. Instead, in the 2000s, a new face of environmental civil society began to take shape. There was noticeable international support for CSOs, large joint events took place, and even despite the local nature of most organisations, there was a genuine willingness to unite to work on complex issues. At the same time, certain structural changes took place within the movement: in the late 1990s, Greenpeace closed its Ukrainian office and revised its international strategy, shifting its focus from nuclear energy to climate change. This global trend gradually reoriented the Ukrainian sector as well.
Environmental activism increasingly shifted from anti-nuclear to a broader environment, climate and energy agenda.
Environmental activism increasingly shifted from anti-nuclear to a broader environment, climate and energy agenda. NGOs began to address issues such as the electricity market, energy efficiency, renewable sources, the wider impact of industry, and the environmental consequences of infrastructure projects such as the construction of pumped-storage hydroelectric power stations and new power lines. With time, climate initiatives and participation in global processes and campaigns integrated Ukraine into the international network fighting climate change. As a result, the anti-nuclear issue has ceased to be the movement’s core focus and has become just one part of a broader discussion on the future of Ukraine’s energy sector, its security, and just transition.
4. How CSOs Work With Chornobyl Topic Today
In the 2010s, environmental organisations like the National Ecological Center of Ukraine have once again turned their attention to the safety of nuclear power - this time in the context of extending the operating life of ageing Soviet-era reactors. Together with specialists, they documented abnormal situations at individual units and sought to draw the attention of the nuclear regulatory authority to the risks associated with extending the service life of equipment designed for entirely different timeframes. Although the regulator likely took some of the comments into account, political pressure significantly influenced decision-making. Ukraine’s dependency on Russian nuclear energy technologies and fuel, as well as transit of European spent nuclear fuel through Ukraine to Russia also caused additional concern, particularly after Russia’s invasion of Ukraine in 2014.
With Russia’s full scale invasion in 2022, long standing nuclear dangers resurfaced. These include Russia’s presence in the Chornobyl exclusion zone, its occupation of the Zaporizhzhia Nuclear Power Plant, the largest nuclear power plant in Europe, and ongoing attacks on Ukraine’s nuclear energy infrastructure. At the same time, nuclear risks have become inseparable from Ukraine’s broader struggle for survival. As a result, civil society now operates in a fundamentally different environment than it did decades ago, with a primary focus on securing power supply, safety and on holding the aggressor accountable for its illegal actions. In this context, Greenpeace returned to Ukraine and officially reopened its office, ushering in renewed and more active communication on nuclear threats viewed through this new lens of war.
Civil society now operates with a primary focus on securing power supply, safety and on holding the aggressor accountable for its illegal actions.
Despite these activities, forty years after Chornobyl, the anti-nuclear movement in its initial form has all but disappeared. As Pasyuk explains, mobilization requires a sense of imminent threat while the extension of reactor lifespans or routine industry issues do not make people feel that they ‘must act now’. Ukrainians tend to think: ‘if the plant is working, let it work’, and it is difficult to attract new activists to issues that require complex technical explanations, lengthy analysis and do not yield quick results. New generations of environmental activists tend to come mainly from the fields of nature conservation, forestry, water resources or biodiversity; those who wish to work on broader systemic issues have, over the last few decades, largely opted for the climate movement rather than the anti-nuclear one.
The legacy of Chornobyl remains significant, but it sets the framework for sensitivity rather than dictating the agenda. For some Ukrainians, the memory of the accident is a personal experience of family histories, evacuations, illness and loss. For schoolchildren and young people it is more of a history lesson, an event that exists in textbooks. Yet it is precisely this historical memory that allows to clearly demonstrate that the potential consequences of a nuclear accident are not an abstraction.
The key challenge lies in the development of a realistic, consistent and safe path for the energy transition.
According to Pasyuk, it remains critically important to establish a clear vision for the future of nuclear energy and the energy system overall: exactly when each reactor unit is to be decommissioned, which funds will finance this process, and what energy solutions will replace the ageing reactors. At present, no such plans exist. Insufficient funds are being set aside for decommissioning, and there is no clear strategy for replacing the nuclear units. Therefore, the key challenge lies not only in balancing the country’s electricity needs against the security risks, but in the development of a realistic, consistent and safe path for the energy transition - a path that cannot rely on the endless extension of the operational life of Soviet-era reactors.
Conclusions
What remains of Ukraine’s post‑Chornobyl environmental civil society 40 years on?
Four decades after the disaster, the mass anti‑nuclear mobilization that once helped erode Soviet authority has largely transformed. The early post‑Chornobyl movement created the foundations of a lasting civic infrastructure: NGOs, watchdog organisations, community networks and advocacy skills that still shape Ukraine’s environmental sector today.
Although the explicitly anti‑nuclear agenda no longer dominates, its legacy endures in a strong culture of public oversight, technical expertise, and the ability to organize coalitions around complex issues such as energy and climate policy. What remains is not the same movement that filled the streets in the late 1980s, but a mature, professionalized civil society whose roots in Chornobyl continue to inform its vigilance, institutional memory, and sensitivity to environmental risk.
Has the Chornobyl experience fundamentally changed how Ukrainians understand nuclear risk during the current war?
Chornobyl has shaped Ukrainian perceptions of nuclear danger in a profound way. On the one hand, most Ukrainians today distinguish between the 1986 catastrophe and nuclear energy as a sector: the majority of the population perceives nuclear energy as a dangerous but useful resource. On the other hand, the memory of Chornobyl provides a vivid reference point that makes the consequences of a nuclear incident feel real rather than abstract. This historical experience informs public awareness during the current war, particularly considering Russia’s occupation of the Zaporizhzhia nuclear power plant and Russian military activity around other nuclear sites.
Nuclear risk is interpreted through a broad security lens: geopolitical risks created by war and energy dependencies, environmental protection issues, the vulnerability of aging Soviet‑era reactors, the absence of long‑term decommissioning plans for nuclear power plants. Chornobyl has not made Ukrainians uniformly anti‑nuclear, but it has embedded a lasting understanding of nuclear danger. The latter shapes expectations of state responsibility, regulatory independence, and the need for a clear, safe energy transition in wartime and beyond.
