In 2010, at the World People’s Conference on Climate Change and the Rights of Mother Earth, held in Bolivia, HOME was launched to oppose and halt geoengineering—the large-scale and deliberate technological manipulation of land, oceans, and the atmosphere.
In 2018, HOME launched its Manifesto calling for the immediate and unequivocal rejection of geoengineering technologies. As stated in the original 2018 Manifesto: “Mother Earth is our common home and its integrity must not be violated by geoengineering experimentation and deployment.” In 2022, the HOME campaign transitioned into an alliance.
In light of the new political and on-the-field developments, the worsening of the climate crisis and its impacts, and the dangerous efforts to normalize geoengineering, HOME Alliance has revisited and revised the Manifesto and our demands to reflect these changing and urgent realities, and to send a clear message: we will not allow geoengineering to hijack our future!
Among other reasons, HOME Alliance rejects all forms of geoengineering,, because they constitute false promises and serve as dangerous distractions from the real solutions that are needed to truly address the climate and biodiversity crises. Geoengineering is an enabler of the extractive fossil economy and other false solutions, such as carbon markets. For any geoengineering technique to impact the climate, it would have to be deliberately deployed on a massive scale, both spatially and in terms of duration. This would result in major, irreversible impacts to ecosystems and communities, with the greatest impact being experienced in the Global South and Arctic circumpolar regions. Deployment at this scale would be impossible to control. Supposed small-scale geoengineering experiments drive technology development with an aim to normalize the dangerous idea that these approaches could have a role. They constitute a slippery slope towards larger-scale experiments and, eventually, deployment.
One of the reasons this moment is decisive is the rise of a new wave of geoengineering ventures, including an Israeli-U.S. startup, Stardust Solutions, which has raised $75 million to advance Solar Radiation Modification (SRM) technologies, an overall increase in the number of geoengineering outdoor proposals and experiments (e.g. four times more geoengineering field experiments were proposed between 2019 and 2023 compared to the previous five-year period), and a big push for some of these highly speculative technologies, which were once dismissed as science fiction, to enter the mainstream climate discourse.
Thus, the Manifesto is a renewed collective statement opposing the dangerous distraction of geoengineering schemes as a means to address the climate crisis, and reaffirming our commitment to real, transformative, rights-based, and gender-just solutions to the climate crisis. While the climate crisis is one of humanity’s most pressing challenges, we cannot justify responding to it with speculative, technological, illusionary “fixes” that are as dangerous, or perhaps more so, than the impacts of climate change itself. We cannot repair an already “broken climate” by breaking it further.
As the global community gathers for the People’s Summit and the COP30 in Belém, Brazil, the stakes have never been higher—not just in terms of the scale of the crisis, but in terms of how we act and respond to it. We cannot allow the climate agenda to be hijacked by high-risk technological proposals backed and pushed by powerful actors with vested interests.
Our home, lands, oceans, and sky are not a laboratory for risky and manipulative planetary-scale technologies. Let’s stop geoengineers, corporations, and governments from gambling with the planet.
Stand with and join us in the fight against Geoengineering
Stand with us and collectively demand
No Geoengineering! Hands Off Mother Earth!
