Google is working on bringing more shade to help cool our cities as the climate crisis worsens. The new Tree Canopy Lab combines artificial intelligence and aerial imaging to help cities see where there are gaps in their tree coverage and tree planting projects. Cities will then know where to plant more trees, Google said.
Google is working with the City of Los Angeles on the project.

“Extreme temperatures are becoming more common in cities where concrete and infrastructure are now creating heat islands — areas that experience higher temperatures, leading to poor air quality, dehydration and other public health concerns,” Google said in a blog post Wednesday. “Trees are increasingly seen as a solution to both lowering street-level temperatures while improving quality of life.”
The Tree Canopy Lab shows what percentage of neighborhoods have tree coverage, as well as population density and areas that are subject to extreme heat. It uses images collected by planes during the spring, summer and fall, including color photos and near-infrared photos. Google AI is then used to scan the images and detect trees, and Google Earth Engine helps analyze this data.

Google’s tree lab has found that 50% of Los Angeles residents live in area with 10% or less tree coverage, and 44% live in extreme heat risk areas.
“Every tree we plant can help stem the tide of the climate crisis,” said Eric Garcetti, mayor of Los Angeles. “When we expand our urban forest, we can sow the seeds of a healthier, more sustainable and equitable future for communities hit hardest by rising temperatures and intensifying heat waves.”
