In October 2023, an innocuous meeting between Aymeric and Martin took a decisive turn.
Both share a conviction: innovation in favor of ecological transition is abundant, but it must be visible to transform the market.
The idea of an association quickly came to the fore.
All that's left is to come up with a name. After several reflections, the obvious is obvious. 425PPM: one number, one symbol. That of the critical threshold for the concentration of CO₂ in the atmosphere, which has been exceeded in recent years. A reminder of the climate emergency and the need to act.
Since then, 425PPM has been supporting transition actors by maximizing their media and digital impact. Innovative start-ups, pioneer companies and structuring events trust them.
The agency is now a team of five people, driven by an unwavering ambition: to bring out game-changing initiatives and to accelerate the ecological transition through the media and digital technology.
425PPM: because the emergency is there. And that those who take action should be heard.
🔬 CO2 concentration, measured in parts per million (ppm), is a key indicator of global warming. A record level of 425 ppm, as observed in May 2023, means that 0.0425% of the air is composed of CO2.
Historically stable at 285 ppm, this concentration has begun to increase significantly since the 1850s. Measured daily since the 1960s by the Mauna Loa Observatory in Hawaii, the ppm level offers a valuable historical reference for understanding climate change.
Did you know that you can calculate the year you were born in ppm? The famous Born in ppm.
