Echosys picto Our mission

We help investors deploy money smartly, and developers and industrial companies get funding efficiently.
We intervene in sectors where we can have the most impact on climate change.


Energy generation is the activity with the largest contribution to CO2 emissions.

Solar, wind, biomass, and hydro power plants can substitute to fossil fuel consumption and reduce global warming.


Land and forests are home to biodiversity and the most natural and efficient CO2 capture systems.

Agriculture and energy projects can be structured as powerful contributors to sustainable land use, ecosystem restoration and CO2 reduction.


Industry accounts for 20% of global energy consumption and 20% of greenhouse gas emissions.

60 to 80% of this energy is waste heat which can be recovered via multiple industrial applications

Our team has a joint expertise in project development, engineering, financing, and investment
