Stratospheric Aerosol Injection:
an effective solution to buy time for other efforts to take hold
This diagram is for illustrative purposes and not drawn to scale.

We deploy our reflective clouds above 12.4 miles (20km) from the Earth's surface using balloons. The reflective clouds stay up for about a year reflecting some of the Sun's rays just like the natural clouds below. Think of it as applying sunscreen spray to protect your skin from the Sun. Just one gram of our clouds offsets the warming effect of one ton of CO₂ for a year.

Inspired by the natural cooling effects of volcanoes, stratospheric aerosol injection (SAI) is a scientific technique that acts like a sunscreen spray for the Earth. The balloons release tiny reflective particles into the stratosphere, creating a thin reflective layer that reduces the amount of heat reaching the Earth’s surface and preventing the planet from overheating. SAI offers a promising solution to combat the immediate effects of global warming.

Back to climate basics
Our current path

To combat climate change, we need a realistic approach rooted in science and technology. While terms like carbon footprint and offsets feel like progress, they barely make a dent.

We believe in a 3-pronged approach, anchored by SAI, and we’ve started taking action with our balloon deployments.
