Controversial Climate Startup Make Sunsets: Unregulated Geoengineering Sparks EPA Concerns and Environmental Risks

April 17, 2025

In recent years, the conversation surrounding climate change has become increasingly urgent, prompting innovative solutions to combat global warming.

Among these, a controversial startup named Make Sunsets has gained notoriety for its unregulated geoengineering practices.

Founded by Luke Iseman, this Northern California-based company is at the forefront of a polarizing approach to climate intervention: launching balloons filled with sulfur dioxide into the atmosphere with the goal of temporarily cooling the planet.

However, the company's practices have sparked significant concern from environmentalists and regulatory bodies alike.

As part of its strategy, Make Sunsets not only seeks to alter Earth's climate but also sells 'cooling credits'—a concept that allows consumers to offset their carbon emissions by paying for the startup's geoengineering activities.

Priced at $30 for a subscription and $5 per ton of CO2, these credits raise ethical questions about climate solutions that may not have undergone rigorous scientific scrutiny.

The U.S.

Environmental Protection Agency (EPA), under the leadership of Administrator Lee Zeldin, has reacted sharply to these developments, calling for a thorough investigation into the startup's operations.

The alarm has been sounded over potential ecological risks and the unregulated nature of these geoengineering experiments, especially given that Make Sunsets has already faced a ban in Mexico for similar actions.

In this article, we will explore Make Sunsets' innovative yet controversial approach to geoengineering, the response from the EPA and environmental experts, and the broader implications these actions have on climate policy and safety.

Controversial Climate Startup Make Sunsets: Unregulated Geoengineering Sparks EPA Concerns and Environmental Risks

Key Takeaways

  • Make Sunsets' unregulated geoengineering efforts raise significant environmental concerns.
  • The EPA is calling for investigations into the startup's harmful practices and potential risks.
  • Geoengineering without regulation could disrupt natural climate patterns and have dire ecological consequences.

Overview of Make Sunsets and Their Approach to Geoengineering

## Overview of Make Sunsets and Their Approach to Geoengineering The ongoing climate crisis has spurred innovative, yet controversial, solutions from startups like Make Sunsets, founded by Luke Iseman.

Operating unregulated in Northern California, the company is making headlines for launching balloons filled with sulfur dioxide into the atmosphere, a method aimed at geoengineering the Earth's climate to temporarily lower global temperatures.

This radical initiative comes with a business model that includes selling 'cooling credits' to offset carbon emissions, costing $30 per subscription or $5 per ton of CO2.

However, this novel approach has raised alarm bells among environmental authorities.

EPA Administrator Lee Zeldin has expressed his concerns, highlighting the urgent need for investigations into Make Sunsets' activities, which he categorizes as potentially harmful pollution.

With over 124 deployments already, Iseman has ambitious plans to scale up operations, prompting the EPA to seek detailed information regarding the environmental implications of releasing sulfur dioxide into the atmosphere.

Notably, Make Sunsets is already banned in Mexico, indicating the contentious nature of their geoengineering efforts.

Critics worry that such interventions may disrupt natural climate systems and lead to unintended consequences, echoing longstanding fears associated with geoengineering.

Iseman has been vocal about his endeavors on social media, celebrating successful launches and his connections to climate activism.

Yet, his methods have faced backlash, particularly from those who find the tactics excessively radical.

The article urges readers to contemplate the repercussions of unregulated geoengineering by individuals operating on ideological motivations.

The activities of Make Sunsets not only highlight the complex intersection of innovation and environmental responsibility but also underscore the necessity for robust regulatory frameworks in climate policy.

In an era where every action counts, the implications of such a startup's operations could resonate far beyond the immediate environment.

Concerns and Implications Raised by the EPA and Environmental Experts

The emergence of Make Sunsets poses critical questions about the balance between innovative climate solutions and environmental safeguards.

As the startup continues its unregulated ventures, the Environmental Protection Agency (EPA) emphasizes the necessity for a structured approach to geoengineering practices.

The deployment of sulfur dioxide in the atmosphere may promise short-term cooling effects, but environmental experts warn that such actions could lead to cascading effects, including alterations in weather patterns, potential stratospheric ozone depletion, and other unforeseen ecological disruptions.

These risks encapsulate the broader dialogue around geoengineering, where the potential benefits must be weighed against the ethical implications and environmental integrity.

The conversation surrounding Make Sunsets serves not only as a case study in the rapidly evolving climate intervention landscape but also reinforces the critical need for comprehensive policies that govern such experimental technologies, ensuring they align with global sustainability goals.
