About
Scale provides strategic guidance and technical support to help clients set and achieve ambitious goals for climate action and natural resource stewardship. We believe that natural and working lands must be central to both fighting and adapting to climate change: they hold the key to generating the negative emissions humanity needs to get to net zero, and are essential to the longterm health and wellbeing of every species on the planet. Forests, grasslands, agricultural lands, and whole ecosystems are the only climate tech that provides food, water, shelter, and spiritual sustenance.
We work at a range of geographic scales, from the parcel level to national policy, to help clients identify and implement durable solutions.
