Climate change is not driven by what we see, but by what remains largely invisible: the continuous accumulation of atmospheric CO₂.
Each year, human activities release nearly 40 billion tonnes of CO₂. Around half of these emissions remain in the atmosphere, directly altering the Earth’s energy balance. While oceans absorb part of this excess, they only delay its effects. Global warming is already underway.
Reducing emissions is essential and must remain a priority. However, stabilising the climate cannot be achieved by mitigation alone. To restore balance, the CO₂ already accumulated in the atmosphere must also be actively removed.
At the gigatonne scale, the scientific consensus is clear: the only solutions capable of operating sustainably at this level are based on photosynthesis. Microalgae, which account for approximately 50% of global photosynthesis and can capture up to 15 billion tonnes of CO₂ each year, have shaped the atmosphere we depend on today.
ALIUM infrastructures are designed around this principle. By industrialising microalgal photosynthesis, making it continuous, measurable, and deployable at large scale, ALIUM enables direct CO₂ capture and transforms a natural biological process into active climate infrastructure.
Climate change is not a matter of opinion.
The challenge is already in front of us.
The question is no longer whether action is necessary, but whether we will act in time — before the cost is passed on to future generations.
