About Us

By using existing technologies and gathering new data, we make it easy and profitable for large buildings to become carbon neutral.

And for us, it’s not enough to reduce emissions by 50% or even 90%. We need to reach zero emissions today—and with Carbon Lighthouse, we have both the means and the motivation to be a catalyst for change.

Our values


We can accomplish more together, so as a team, we listen actively and seek to learn from one another.

Question Asking

Are things the way they are because they need to be, or because no one else has found a way to improve them?


We are honest, consistent and forthright with our clients, our teammates and ourselves.

Getting it done

We are on a mission, and there’s no time to waste, so let’s move quickly based on real-world data.

The Carbon Lighthouse Mission

Because stopping climate change will only happen if we can make it easy and profitable, together we are engineering new ways to erase the 20% of global emissions from non-residential buildings.
