BELÉM (November 13, 2025) — As COP30 and the Peoples Summit (Cúpula dos Povos) opens in Belém, Brazil, this week, Hands Off Mother Earth (HOME) Alliance, a global network of Indigenous Peoples, human rights, grassroots, climate justice and feminist groups has relaunched its call for an end to geoengineering. The Manifesto ‘Home Alliance Manifesto Against Geoengineering – Our HOME is not a Laboratory’ was launched today at the Peoples’ Summit as a clarion call to reject geoengineering, defend Mother Earth, and advance real climate justice solutions.
The manifesto warns that geoengineering, the large-scale deliberate technological manipulation of the Earth’s systems, is a dangerous distraction and a false solution that risks deepening inequality, violates Indigenous Peoples rights, and destabilizes ecosystems. It exposes how powerful interests are using carbon markets to open the door to risky, planetary-scale outdoor experiments that will cause harm to communities, ecosystems, biodiversity and climate systems. These dangerous schemes are likely to find entry through the Paris Agreement’s Article 6 mechanisms but are an illusionary fix since they don’t address the root causes of the climate crisis.
However, communities across the world have already resisted and defeated geoengineering experiments from the Arctic Ice project to St. Ives Bay while reminding the world that real solutions lie in centering Indigenous knowledge, community led solutions and the urgent phase out of fossil fuels.
Our message is clear: Our home, our lands, our oceans, and our sky are not a laboratory. Hands Off Mother Earth!

Reactions from HOME Alliance Members
Adrienne Aakaluk Blatchford, Geoengineering Outreach Organizer Indigenous Environmental Network said:
The urgency to uphold the geoengineering moratorium and to halt all projects aimed to manipulate the climate are needed to move towards an Indigenous Led Just Transition for divestment from the petrochemical and extractive industries and implement real climate solutions. Indigenous Environmental Network continues to hold the line and stand in solidarity with all who stand up and fight big box corporations and carbon schemes that are greenwashing language and pushing false narratives for profit. The urgency to solve climate change can not be rooted in unproven technologies, but in the hands of the People who have stewarded their ancestral lands since time immemorial with the symbiotic relationships they continue to hold with their ecosystems. The time is now to be good Ancestors and work for people over profit to ensure our Mother Earth will thrive for not just us, but future generations to come.
Lili Fuhr, Fossil Economy Program Director, Center for International Environmental Law (CIEL) said:
“Storms, fires, droughts, and other extreme events show we’ve already passed safe carbon limits—the danger is unmistakable. This crisis is fueling a toxic mix of desperation and urgency, driving proposals for extreme measures such as solar and marine geoengineering. Meanwhile, major polluters continue to push dangerous distractions like carbon removal technologies, including Bioenergy with Carbon Capture and Storage (BECCS) and Direct Air Capture (DAC). Now more than ever, we need civil society to heed the scientists’ warnings about the risks and irreversible harms of temperature overshoot pathways, and to follow the leadership of African and Pacific governments in calling for a global commitment to the non-use of solar geoengineering. The Center for International Environmental Law (CIEL) is proud to be a member of the HOME Alliance, and we urge our movement partners around the world to join us at this critical moment in saying: ‘Hands Off Mother Earth, No to Geoengineering.’”
Mar Zepeda, Legislative Director, Climate Justice Alliance said:
“As the push to implement geoengineering becomes increasingly aggressive and commercialized, we must do all we can to protect all peoples, the land, the seas, and the atmosphere itself from this dangerous false approach. Geoengineering carries the risk of disrupting Earth’s systems while doing nothing to address the root causes of the climate crisis. We must honor, prioritize and invest in solutions that are proven to work and do not exacerbate the climate crisis. Grounding in Indigenous wisdom, Mother Earth, and frontline climate solutions that are community controlled and don’t rely on oil, gas, and other extractive industries to operate is the only way forward.”
Mfoniso Xael, Programmes Manager, Health of Mother Earth Foundation said:
Health of Mother Earth Foundation stands firmly with the Hands Off Mother Earth Alliance in rejecting the illusion of control that geoengineering sells. These false solutions, marketed as climate fixes, are dangerous distractions that shift focus from ending fossil fuel dependence and restoring ecological balance. They risk turning our skies, lands, and oceans into testing grounds for unproven technologies that deepen inequality and endanger lives.
For Africa, geoengineering poses a double injustice. Our people, who have contributed least to the climate crisis, would bear the brunt of its unpredictable and potentially catastrophic side effects; disrupted rainfall, threatened food systems, and violations of sovereignty. Real solutions to the climate emergency must come from the wisdom of communities, the defense of ecosystems, and a decisive move toward a fossil-free, people-centered future. Our home is not a laboratory.
Josue ARUNA, Country Director of Congo Basin Conservation Society CBCS-Network said:
English
The world must know that we are tired of false climate solutions. The geoengineering technologies being imposed on us violate our rights and cultural values, destroy our shared future and devastate our economies in rural areas that lack resources.
Continuing to fund these technologies is distracting humanity from finding ideal solutions to climate financing.
Africa is not ready to receive you. Stop with your distractions; Africa is not your laboratory. By refusing to provide direct funding for forest restoration, agroecology, biodiversity conservation and land security for indigenous peoples and local communities, you are killing our destiny. Stop your nonsense of the century.
French
Le monde devrait savoir que nous sommes fatigués de fausses solutions climatiques, les technologies de geoingénierie que l’on nous impose violent nos droits, nos valeurs culturelles, détruisent notre avenir commun et nos économies dans les zones rurales sans moyens.
Continuer à financer ces technologies c’est enfoncer l’humanité dans la distraction en évitant de trouver les solutions idéales au financement climatiques.
L’Afrique n’est pas prête à vous recevoir. Arrêtez avec vos distractions, l’Afrique n’est pas votre laboratoire. Vous refusez de donner les fonds directs en faveur de la restauration des forêts, de l’agroécologie, de la conservation de la biodiversité, de la sécurisation des terres en faveur des peuples autochtones et communautés locales et vous tuer notre destinée. Arrêtez vos bêtises du siècle.
Gary Hughes, Co-Director and Americas Program Coordinator, Biofuelwatch:
The relaunch of the Hands Off Mother Earth Alliance manifesto is an exciting opportunity for global climate justice organizations to reaffirm a unified position against the proliferation of dangerous speculative technologies that would only make the climate and biodiversity crises worse. Whether it be feedstock intensive carbon removal schemes, the chemical manipulation of marine ecosystems, or outlandish atmospheric albedo hacking fantasies, a broad array of geoengineering climate interventions are being proposed that put our communities and the natural world at risk. In joining the relaunch of the manifesto Biofuelwatch stands with our Alliance partners to say “Hands Off Mother Earth!”
Veronica Villa, Senior Campaigner and Researcher, ETC Group said:
The expansion of geoengineering in climate negotiations comes with huge risks, and developments within the UNFCCC contrast with the cautious approach to geoengineering being taken in other intergovernmental fora such as the Convention on Biological Diversity and the London Convention on ocean dumping.
This time again, COP30 should not be a ‘sugar-coated poison pill’ that will push forward reliance on risky and unproven geoengineering technologies. Technologies such as Carbon capture and storage (CCS), Bioenergy with carbon capture and storage (BECCS), massive-scale monoculture of industrial seaweed species in the ocean in the pursuit of ‘blue carbon’ and other dangerous proposals that will not contribute to the phase-out of fossil fuels. Instead, it will increase emissions and worsen the climate crisis. It will also carry new risks to nature, health and the environment and expand the violation of human rights that carbon markets and offset projects have already triggered.
In such a time, ETC group is invigorated in resounding the voices against false ‘solutions’ and join our allies and partners in the relaunching of the HOME Manifesto and state together– Hands Off our Mother Earth!
Linda Schneider, Senior Programme Officer International Climate Policy, Heinrich Boell Foundation said:
Climate geoengineering will not fix the climate, it will not buy us time and it will not help us address the climate crisis. Quite the contrary: Industrial Carbon Dioxide Removal (CDR) will lead to a further grab of land, energy, water and resources in countries of the Global South under the guise of climate policy – all while giving a free pass to polluters to continue emitting and offset their emissions through international carbon markets. Marine geoengineering carries great risks for our shared oceans and vitally important marine ecosystems, and it has not been proven to be effective. It absolutely needs to be kept out of international mechanisms such as Article 6. Finally, solar geoengineering as a planetary-scale manipulation of the Earth’s climate system would only lead to more climate breakdown.
The Heinrich Boell Foundation is excited to join our allies and partners in the relaunch of the Hands Off Mother Earth Alliance manifesto today to say: No to geoengineering and other false solutions, and yes to climate justice and real solutions!
Dylan Hamilton, False Solutions Coordinator, Alliance of Non-Governmental Radical Youth (ANGRY) said:
The HOME manifesto affirms that those in power are desperately searching for the next technology that would allow us to continue business as usual. The climate crisis did not happen in a vacuum – it is a symptom of our failed relationship with the natural world and of greed for eternally increasing profits.
Returning land to Indigenous peoples, returning power to the people, and ending extractivism are real solutions. This manifesto clearly shows how the techno fixes that are becoming increasingly popular with governments are not. The youth will not stand silent in the face of geoengineering, Carbon Dioxide Removals (CDR), and the myriad other dangerous distractions that put the future of our planet in peril.
