European Parliament calls for ban on gene drive technology

Report on the EU' Biodiversity Strategy for 2030: Precaution prevails

9.06.2021, Berlin -The European Parliament yesterday confirmed it‘s precautionary stance towards the use of a new genetic engineering technology called gene drive.[i] In it´s report on the EU’s Biodiversity Strategy for 2030, adopted at the European Parliament’s plenary on 08.06.2021, Parliamentarians demand that no releases of genetically engineered gene drive organisms should be allowed, including for nature conservation purposes, in line with the precautionary principle.“

Mareike Imken, coordinator of the European Stop Gene Drive Campaign welcomes this decision and comments:With its position today, the European Parliament recognizes that this technology raises a series of scientific, regulatory, societal and ethical questions and concerns. As its use could severely harm biodiversity, the European Parliament calls to postpone any environmental releases until these questions have been addressed and settled. This is an important message that should feed into the ongoing discussions about global regulations at the next meeting of the International Union for Conservation of Nature (IUCN) in September in Marseille and those of the Convention on Biological Diversity in October in Kunming, China.“

27civil society and science organizations from across the EU had sent a letter to Parliamentarians in support of the amendment ahead of the vote. It provides reasonable suggestions on how to implement the European Parliament’s previous position in its resolution on the 15th meeting of the Conference of Parties (COP15) to the Convention on Biological Diversity (2019/2824(RSP)“.

In that previous position, adopted in January 2020, the European Parliament had called on the Commission and the Member States to call for a global moratorium at the COP15 on releases of gene drive organisms into nature, including field trials, in order to prevent these new technologies from being released prematurely and to uphold the precautionary principle, which is enshrined in the Treaty on the Functioning of the European Union as well as the CBD.

World Malaria Day: Do we need gene drives to fight malaria?

Gene drive technology carries high risks. Yet it is being promoted by the Bill & Melinda Gates Foundation as a solution to malaria. On the occasion of World Malaria Day, the Stop Gene Drives campaign is launching a project that presents different perspectives on the issue of malaria control and highlights alternative, possibly less risky approaches and innovations to combat malaria.

Infectious diseases such as malaria, dengue fever and Lyme disease are transmitted to humans by so-called vectors, such as mosquitoes or ticks. In the case of malaria, the pathogen and thus the disease is spread exclusively by Anopheles mosquitoes. A global program of malaria control has so far helped to roll back the disease in many regions of the world. Already 38 countries have been certified malaria-free, but there remain 86 countries where malaria control has not been adequately implemented, resulting in several hundred thousand deaths.

This is where the discussion of Gene Drive technology comes into play. Mosquitoes are genetically modified in the laboratory using a process known as CRISPR/Cas so that they pass on a new trait to all their offspring, even if that trait causes the population or the entire species to become extinct. Gene drive mosquitoes produced in this way are expected to massively reduce the number of Anopheles mosquitoes in Africa and thus prevent the transmission of malaria. Gene drives are therefore being promoted as an effective technological solution to combat malaria.

Mareike Imken, coordinator of the Stop Gene Drive campaign, explains in a short interview what concerns there are about the use of gene drive technology and what the goal of the European Stop Gene Drive campaign is. (To the interview)

A leading role in the development of such gene drives is played by the international research consortium Target Malaria, which is largely funded by the Bill & Melinda Gates Foundation. In an interview with us, Dr. Andreas Wulf of Medico International explains their influence on global health policy and the selection of priorities and measures, including those to combat malaria, that are influenced by them. (To the interview)

Target Malaria's plans to use gene drives have already reached the stage where the first projects have been launched in Africa, including Burkina Faso. In July 2019, Target Malaria conducted its first field tests in Burkina Faso using genetically modified sterile mosquitoes that did not yet carry Gene Drive. These trials were considered a precursor to the release of Gene Drive mosquitoes in a later phase of the project. These and subsequent tests have met with resistance from parts of the population in Burkina Faso, as Ali Tapsoba, human rights activist, explains in his interview with us. (To the interview) He is the spokesperson for civil society resistance to the release of Gene Drives in Burkina Faso. Treatment and profilaxis with Artemisia teas grown in Africa are among the measures he would prefer over the use of Gene Drive technology. However, the World Health Organization (WHO) warns against this. Internationally renowned professor Pamela Weathers of Worcester Polytechnic Institute explains how effective and safe Artemisia tea infusions are for treating or preventing malaria in her interview with us. (To the interview)

Burkina Faso has, according to epidemiologist Dr. Sory, a strong strategy to combat malaria. A cocktail of different measures is needed to fight this disease and decrease other diseases at the same time. Better drainage systems, awareness raising and access to health care are just a few points raised in the interview. (To the interview)

Artemisinin is a component derived from the Artemisia plant and present in most anti-malarial drugs nowadays. Lucile Cornet-Vernet and Arnaud Nouvion from the Maison de l'Artemisia, talk about the potential to use the plant as tea as a preventive and curative method for malaria. Furthermore, they make clear that final clinical studies are needed to get the plant approved by the WHO. (To the interview with Lucile and Arnaud)


162 organizations call for global gene drive moratorium

A broad coalition of 162 organizations has sent an open letter to Frans Timmermans, Vice President of the European Commission. It demands that plants and animals modified using new genetic engineering methods continue to be strictly regulated in the future. Furthermore, the EU Commission should support a global moratorium on gene drive organisms.

The existing EU genetic engineering standards ensure the implementation of the precautionary principle and protect the environment and consumers, wrote the organizations from the fields of environmental and consumer protection, agriculture and the food industry. Farmers and consumers would be free to choose whether to eat or grow genetically modified crops. The current occasion for the open letter is a study on the current status and future regulation of genetically modified organisms in the European Union (EU).  The governments of the European member states had asked the EU Commission in November 2019 to prepare such a study. It should take into account various aspects, including scientific progress, the legal situation, as well as a publication of the "European Group on Ethics in Science and New Technologies." The European Commission has announced that they will publish the study at the end of April.

The authors of the letter to Timmermans and other members of the EU Commission also call on the Commission to ensure that the regulation of genetic engineering in the UK remains EU-compliant after Brexit. This is because the British government is currently planning to revise its genetic engineering legislation. As reported by Infodienst, it invited stakeholders to a consultation process at the beginning of the year, which ended in mid-March. The organizations are now calling on Timmermans to lobby the UK government to drop these plans. If genetically modified plants were to be less strictly regulated in the UK in the future, this would also affect the trade with the EU.

Finally, the 162 organizations call for the EU Commission to support a worldwide moratorium on the use of so-called gene drive organisms. Gene drive organisms result from a special application of new genetic engineering. This poses the risk that entire species of organisms could be severely decimated or wiped out. The European Parliament had already spoken out in favor of a global moratorium in January 2020 in the form of a petition. Especially in times of "ecological crisis, when a million species are threatened," experiments with a technology that is also referred to as "extinction on demand" cannot be carried out, according to the justification.


Survey: EU citizens reject genetic engineering of wild species with Gene Drives

Should humanity release genetically engineered gene drive organisms into nature? The response of a majority of citizens in eight European countries is: “No, the risks are too high”. This first opinion poll on the subject shows high levels of rejection (46% - 70%) and very low levels of support (7% - 16%) for the use of Gene Drive technology in the environment. The survey amongst nearly 9.000 people is representative of 280 million EU citizens. It was commissioned by nine NGOs demanding an informed and inclusive public debate and a global moratorium on the environmental release of this new type of genetically modified organisms. The survey also reveals that a large proportion of respondents is still undecided (14% - 27%) or did not know how to answer (1% - 24%).

"Such a powerful technology with potentially irreversible consequences for wild species and all their ecosystems must be controlled by strict international rules and procedures of decision making. We do not believe that the release of gene drive organisms from the lab into the environment should happen at all. At least, it would require strict international standards of risk and technology assessment and a prior inclusive, democratic decision making based on precaution and the prior informed consent of all peoples and states potentially affected" states Mareike Imken from Save Our Seeds, Germany, who coordinates the European Stop Gene Drive campaign."

A large majority of respondents (65%-82%) agree that environmental releases of gene drive organisms should be postponed until there is scientific proof that their release would not harm biodiversity, human health, agriculture or peace. A similar majority (61% - 85%) agrees that the authorisation of environmental releases of gene drive organisms that could spread globally should require a global consensus.

This representative survey was conducted by the international market research institute YouGov and polled 8.826 citizens, from 8 EU countries, including Germany, Italy, France, Spain, Poland, Denmark, Sweden and Bulgaria in December 2020. It was commissioned by WeMove Europe, Save Our Seeds (Germany), Skiftet (Sweden), France Nature Environnement (FNE) (France), POLLINIS (France), OGM Dangers (France), Bund für Umwelt und Naturschutz (BUND) (Germany), Deutscher Naturschutzring (DNR) (Germany), Umweltinstitut München (Germany), Za Zemiata (Bulgaria).

Online-Discussion: Gene Drives - Protecting People and Nature through Genetic Extermination?


Ricarda Steinbrecher, geneticist and board member of the European Network for Scientists for Social and Environmental Responsibility (ENSSER), emphasized that it is difficult or even impossible to make reliable predictions about the effects of a future application of Gene Drives, especially at the current time. After all, organisms are released which then independently carry out the genetic modifications in each generation. "Mistakes can be made every time. Every time, something else can be added." To ensure the preservation of biodiversity, new technologies such as Gene Drives must be looked at very closely to ensure that they do not pose any risks to our ecosystems. This is why she strongly advocated the precautionary principle during the international negotiations on the regulation of gene drive technology at the UN Convention on Biological Diversity. As a long-standing scientific advisor and participant in expert groups within the UN Convention on Biological Diversity, she reported that there is a strong influence of lobby groups on these expert bodies: For example, the Bill & Melinda Gates Foundation, one of the main financiers of the technology, had invested 1.6 million dollars in a PR agency to increase the acceptance of Gene Drives. She concluded: "The pressure to implement this technology is not commensurate with the risk."

Ali Tapsoba de Goamma, human rights and environmental activist from Burkina Faso and spokesperson for a civil society association of 40 organizations for agroecology and against Gene Drives (CCAE), reported that since 2012, the project Target Malaria has been preparing to decimate malaria-transmitting mosquitoes in Burkina Faso by means of Gene Drives. In 2019, the first field tests with genetically modified male mosquitoes that are not capable of reproducing took place, but not any Gene Drive Organisms have been released yet. Ali Tapsoba de Goamma criticized that Target Malaria had obtained the consent of the government and village leaders for these tests, but not the consent of the entire population of Burkina Faso. Rather, they had taken advantage of the fact that there are so many illiterate people in the local villages. The majority of the inhabitants of Burkina Faso are against these experiments. He raised the question: "Why not try this first in scientifically better equipped countries, but in Burkina Faso?" In his view, Burkina Faso was in a position to combat malaria itself. He said that this does not require gene drives, but a good health concept.

Dr. Andreas Wulf, doctor and consultant for global health at the medical emergency aid organization Medico International, emphasized that epidemics like malaria require long-term strategies. The idea of trying to solve such a disease with the one-time use of a technology without continued commitment is questionable, he said. One should not rely on such a "technological fix". Experience in combating other epidemics has shown that the success of the measures depends on good cooperation with the people on the ground and finding local solutions. He also criticized from a democratic point of view: "It is a problem that so much decision-making power is given to these private actors, the companies / foundations. A handful of people choose which area of research to invest in. In addition, the media coverage of research is also financially supported by these foundations". Dr. Andreas Wulf concluded that these private funds need to be embedded in the public health systems.

Mareike Imken, head of the Stop Gene Drive campaign of Save Our Seeds, explained that with the European campaign, which is supported by many organizations throughout Europe, she wanted to initiate a critical discussion in society and politics about "whether and if so, under what circumstances we want to use this technology and what restrictions it needs."
She went on to explain: "Gene Drives provides us as humanity with a tool to specifically eradicate or change wild species. In times of a species extinction that is existential for mankind, this must be considered and ethically discussed. This should not be decided lightly by those few people". She also points out that "the knowledge about Gene Drives is not yet sufficiently advanced".
In order to have time for this discussion, in-depth risk research including technology assessment and the development of internationally valid rules and decision-making mechanisms, a global moratorium on the release of gene drive organisms is needed. This moratorium must be adopted at the next Conference of the Parties of the UN Convention on Biological Diversity (COP 15).


78 organizations call on the European Commission to enact a temporary ban on the novel Gene Drive technology

Gene Drive technology: Species extinction through genetic engineering?

In an open letter initiated by Greenpeace EU, Friends of the Earth Europe, IFOAM EU and the German initiative Save Our Seeds, 78 environmental, agricultural, animal welfare and development aid organizsations from all over Europe are calling on the EU Commission to outlaw the release of so-called Gene Drive Organisms in the EU and internationally. With this new application of genetic engineering, entire animal populations and species in nature could be reprogrammed or eradicated.

Enabled by the genetic engineering method CRISPR/CAS9, mosquitoes, mice, fruit flies and other organisms can be manipulated in the laboratory to pass on a certain trait and the mechanism for genetic manipulation to all offspring and across generations. In this way, Gene Drive Organisms can replace their relatives in nature. The Gene Drive trait also asserts itself when it is deadly to the survival of the species – thereby ovveriding the normal rules of evolutionary selection.

The signatory organisations are calling on the EU to advocate a global moratorium on the release of Gene Drive Organisms at the next Conference of the Parties (COP 15) to the UN Convention on Biological Diversity (CBD). The European Parliament had already called for such a moratoirum in a resolution from January this year, responding to a call from over 200 signatories from Europe and worldwide.

"The loss of biodiversity is one of the greatest challenges of our time. While the risks of Gene Drive technology have not yet been scientifically assessed, it could have a massive impact on already damaged ecosystems. It is irresponsible to expose species and ecosystems to further risks“ explains the initiator of the European "Stop Gene Drives" campaign, Mareike Imken from the German initiative Save Our Seeds.

She adds: „The EU Commission recently presented its biodiversity strategy, with which it wants to make the EU a global pioneer for the protection of biodiversity and put an end to the ongoing mass extinction of species. The Gene Drive technology however is designed to drive wild populations and species into self destruction. The use of such a technology contradicts the aim of biodiversity conservation and the precautionary principle, which is the basis for international and EU nature conservation law. A global moratorium would give us the time to assess environmental and health risks, publicly evaluate and discuss this technology and to establish missing regulations and global decision-making mechanisms. In the meanwhile, noone in the world should use this technology."

29 German Organizations call for a Global Gene Drive Moratorium

In a joint open letter sent to the German federal ministers Karliczek, Klöckner and Schulze on February 19, 2020, an alliance of 29 German organizations called on the German government to support a global gene drive moratorium in the upcoming international negotiations.

The reason for the joint letter were important EU and international decisions with regard to the gene drive technology:
At the Conference of the Parties to the UN Convention on Biological Diversity planned for October 2020 in China, the German federal government could play an important role within the scope of its EU Council Presidency. Furthermore, the German government would be able to already set the course for the regulation of this technology at the expert conferences taking place in advance of the convention, especially at SBSTTA 24 planned for June 2020 [postponed to May 2021 due to COVID].

In addition, as part of Germanys membership in World Conservation Union (IUCN), the German government could input to a consultation process on draft resolution 075 on the role of synthetic biology (including gene drives) for the protection of biodiversity within the IUCN, ahead of World Congress planned for May 2020 [postponed to September 2021). This resolution is meant to provide the basis for an inclusive discussion process within IUCN. Its members are invited to exchange views on the potential role of applications of synthetic biology, including gene drives, for the conservation of biodiversity. At the IUCN World Congress 2024, the world conservation organization will vote on its official position on this issue.

In its letter, the alliance calls on the German federal government to follow the European Parliament's vote of January 16, 2020, at the CBD COP 15, in which the European Parliament petitioned the EU to motion for a resolution calling for a global moratorium on the release of gene drive organisms into nature at the next Conference of the Parties to the UN Convention on Biological Diversity in order to prevent premature experiments with the technology in nature.

European Parliament calls for a Global Gene Drive Moratorium

At its plenary session on January 16, 2020, the European Parliament defined its position for the 15th Conference of the Parties to the UN Biodiversity Convention (COP 15 CBD). In their resolution, MEPs call on the EU to support a global moratorium on gene drives in the international negotiations of the CBD. In a joint letter, an EU-wide alliance of more than 50 NGOs, including Greenpeace, Friends of the Earth Europe and IFOAM EU, had previously called on MEPs to vote for such amendments.

The next Conference of the Parties (COP 15) to the CBD  in China could be one of the last moments to stop planned releases of gene drive mosquitoes by the Target Malaria project. A release of gene drive organisms would cause an uncontrollable spread of the genetically modified organisms in an unprecedented manner - and result in a global spread and irreversible change or damage to ecosystems. Once released, there is currently no way to remove gene drive organisms from the wild or to reverse changes and damage to ecosystems, food webs and biodiversity. Hence, such a release is contrary to the precautionary principle. This principle was created by the CBD specifically to protect biodiversity and forms the basis of both European and German nature conservation law.

Gene drives regulated for the first time in genetic engineering law

On June 7, 2019, the Federal Council spoke out in favour of tightening the safety requirements for laboratory experiments with gene drive organisms (GDO) in the Genetic Engineering Safety Ordinance. In addition, it also demands the development of GDO-specific safety measures and calls on the German government to give special weight to nature conservation.

Mosquitoes, flies and mice, but also plants can be modified by a new genetic engineering method called gene drive in such a way that they quickly and comprehensively spread a new trait and in wild populations. Through a special application of the so-called CRISPR-Cas technology, the genetic manipulation itself can be passed on and thus trigger a genetic chain reaction in nature that cannot be controlled in time or space. By releasing such gene drive organisms, entire populations or species in nature are to be genetically modified or even eradicated. Experiments with gene drive organisms in the laboratory involve the risk of experimental animals escaping. Even a few released GDOs could theoretically lead to the extinction of a species in nature.

After an alliance of NGOs (the AbL, BUND, GeN, IG-Saatgut, Testbiotech and Save Our Seeds) drew attention to this danger in an open letter, the federal states responsible for genetic engineering safety became active. At the plenary session of the Federal Council on June 7, 2019, the federal states responsible for the supervision of genetic engineering decided to set a safety level 3 (out of a possible four; the second more serious risk classification) for laboratory experiments with gene drive organisms for precautionary reasons. In an amendment to the Genetic Engineering Safety Ordinance, the federal government included GDOs in the ordinance for the first time and only provided for safety level 2 for laboratory experiments. In addition to this amendment, the federal states appealed to the federal government "to give special weight to the objects of protection under § 1 No. 1 of the Gene Technology Act and in particular to nature conservation in the future design of the specifications for the risk assessment and safety classification of gene drive organisms, over and above the regulations on gene drive organisms laid down in the Ordinance for the Reorganisation of the Law on Safety Levels and Safety Measures for Gene Technology Work in Gene Technology Facilities, taking into account the precautionary principle".

Following the Federal Council’s decision, the Genetic Engineering Safety Ordinance has become operative and includes gene drive organisms in the regulation of genetic engineering law for the first time.
However, there is also a catch: after the automatic classification of gene drive organisms in safety level 3, the Central Commission carries out a case-by-case assessment for Biological Safety (ZKBS). Based on this assessment, the ZKBS can select a different safety level, including safety level 1, which assumes that the risk to the environment and human health posed by the explored GMOs is negligible and therefore does not require any special safety requirements.

For this reason, the Federal Council's welcome decision was only the first, urgently required step. Since the Genetic Engineering Safety Ordinance is not yet designed to cover the risks posed by genetically modified organisms to biodiversity and the environment, the ZKBS and the federal states should draw up specific safety measures for this new class of genetically modified organisms as quickly as possible. In addition, the expert position on nature conservation issues within the ZKBS, which has been vacant for years, must now be filled quickly. We can no longer continue to perform safety classification and risk assessment of gene drive organisms without giving special weight to nature conservation.

Gene Drive Symposium in Bern - Wiping out unwanted species with CRISPR-Cas?

Gene Drive Symposium in Bern - Wiping out unwanted species with CRISPR-Cas?

An interdisciplinary gene drive symposium was held in Bern on May 24, 2019. A report was published highlighting scientific, ecological, social, ethical and regulatory issues related to the gene drive technology.

What is a gene drive?

CRISPR-Cas makes it possible: Gene drives are a genetic engineering process that is used, among other things, with the genetic engineering tool CRISPR-Cas to spread certain traits – such as infertility – quickly and permanently in wild animal and plant populations. The release of such gene-drive organisms is intended to genetically modify or even eradicate entire populations or species in nature. The Gene Drive Symposium in Bern discussed possible applications, social, ethical and ecological consequences as well as regulatory conditions for the use of this technology, which has so far only been tested in the laboratory. The gene drive report published there summarizes the findings.

How does a gene drive work?

CRISPR-Cas is a genetic engineering tool that can search for specific DNA sequences in the genome and break the DNA strands at these points. Genetic engineers make use of the cell’s own repair mechanisms for genetic manipulation: To create a gene drive, the genetic material for CRISPR-Cas is made available to the cell as a repair template. The cell copies this gene sequence into the fracture site and binds the broken DNA. Since the genetic engineering tool itself is thus present in an active form in the genome of the organism, it can become active each time the organism reproduces and copy itself into the genome of the reproductive partner’s gamete. In this way, almost all descendants of a gene drive organism inherit the gene drive and the trait that thus becomes widespread.

Fields of application

The largest field of application for GDO (gene drive organisms) in the future could be agriculture. US researchers and farming associations in particular hope that this technology will be able to decimate insects such as the cherry vinegar fly, aphids and the meal beetle. Overcoming herbicide and pesticide resistance in yield-reducing weeds or insects is also on the wish list of future commercial uses. Gene drives could also be used as biological weapons against plants, animals and humans. For this reason, the US Military Research Institute (DARPA) is one of the largest financiers of gene drive research.

The use of gene drives in malaria-transmitting mosquitoes is the most advanced project and, according to the project team of Target Malaria, will be ready for outdoor testing within five to ten years. Target Malaria, funded by the Bill and Melinda Gates Foundation, aims to eradicate the Anopheles mosquito in Burkina Faso or to genetically modify the mosquito to stop the transmission of malaria.

The nature conservation organisation Island Conservation, on the other hand, hopes to use gene drive organisms to combat invasive rodents that have been introduced into island ecosystems and threaten their biodiversity. For this reason, the idea of using gene drive organisms for nature conservation has been the subject of controversial discussion within the World Conservation Union (IUCN) for several years.

Open ecological, social and ethical questions

Gene drives turns nature into a genetic engineering laboratory. If the gene drive organisms created in the laboratory, for example mosquitoes, flies or mice, are released into nature, they set off a genetic engineering chain reaction that is currently neither spatially nor temporally limited. The result would be a global spread of the new genetically modified organisms. The transformation of the genetic engineering tool CRISPR-Cas, which is prone to mutations and errors, in wild populations is scarcely predictable. Unintended ecological consequences of emerging resistance and mutations, outcrossing into related species or unexpected effects on non-target species would probably be irreversible. Disturbances in the animal food chains and the resulting negative consequences for human food security could not be ruled out. It is questionable whether released gene drive organisms could be retrieved, or whether the ecosystems changed as a result could ever be restored to their original state.

There are also concerns from ethical and social perspectives: Should we presume to override the evolutionary rules of nature so fundamentally? Can such an invasive, totalitarian and disruptive technology, which has been based on patent claims from the beginning, even be adequately controlled? Is such a technology controllable? Which existing alternatives or potential less risky and more democratic solutions will be neglected or not developed at all if billions are currently invested in this high-risk technology?

SOS campaign for a global gene drive moratorium

For Save Our Seeds, gene drives are the most dangerous application of genetic engineering in the environment to date. That is why Save Our Seeds and hundreds of other civil society organizations are calling for a worldwide moratorium on the release of gene drive organisms into the wild. Save Our Seeds wants to spark broad, critical discussion about this technology in society and politics and to win over decision-makers and scientists at national, European and global level to stop the application of this technology before the first specimens are released into the wild. At the same time, SOS promotes respectful treatment of nature that preserves biodiversity and makes it available for human use – instead of exterminating individual species or manipulating them in such a totalitarian way for short-term purposes.

If you would like to support this cause, you can sign the petition for a global gene drive moratorium here.

More detailed information on gene drives from a scientific, ecological, social, ethical and regulatory perspective can be found in the Gene Drive Report published by ENSSER, VDW and CSS at the Gene Drive Symposium in Bern.

At the Gene Drive Symposium on May 24, 2019 in Bern, gene drive developer Kevin Esvelt from MIT in Boston and Ignacio Chapela, Professor of Microbial Ecology at the University of California at Berkeley and Ernst-Ulrich von Weizsäcker discussed possible applications, technical and ecological risks as well as social consequences of the gene drive technology.
Further video recordings of discussions and contributions to the symposium can be found at
