Stuttgart, Germany – Robert Bosch Venture Capital GmbH (RBVC), the corporate venture capital company of the Bosch Group, has completed an investment in Aclima Inc., a startup based in San Francisco, California. Aclima is a leader in hyperlocal air quality and greenhouse gas measurement and analysis. Their platform helps governments, communities, and enterprise customers accelerate action to reduce emissions and protect public health.

“Aclima has built an expansive mobile and stationary sensor network that generates billions of measurements about our most critical resources,” says Dr. Ingo Ramesohl, Managing Director of RBVC. “Bosch invents and delivers connected solutions for a smarter future across transportation, home, industrial, and many other fields. What Aclima has achieved in connected environmental sensing is an impressive feat. Together, we can accelerate Aclima’s ability to support customers in taking decisive and data-driven climate action, supporting Bosch’s guiding principle “Invented for Life”.”

Novel approach with rigorous scientific validation

Aclima has pioneered a new class of measurement and analysis tools that make air pollution and climate-changing emissions visible at the street-level, and at the scale of entire cities and states. To deploy its mobile sensing network, Aclima upfits emission-free vehicles with their sensing devices. As the cars drive through streets, air samples pass through a specially designed intake and are then routed to the device for initial analysis before streaming the measurements results to the cloud. Each week, Aclima sends billions of air quality data points to their cloud-based software platform where it is combined with other data streams for use by governments, communities, and businesses to inform actions that reduce emissions and their impacts.
"Air pollution takes millions of lives and costs billions of dollars every year, and is now linked with higher COVID-19 death rates," said Davida Herzl, co-founder and CEO of Aclima. “We’re thrilled by the potential for collaboration with Bosch that RBVC enables. With this coalition of investors, we’re expanding our capacity to support our customers and community partners in their critical efforts to reduce emissions and protect public health.”

The $40 million Series B round was led by Clearvision Ventures. Other new investors joining Aclima on their journey include the Microsoft Climate Innovation Fund, GingerBread Capital, KTB Network, ACVC Partners, and Splunk Inc. Existing shareholders participating in the round include Plum Alley, Kapor Capital, Rethink Impact, the Schmidt Family Foundation and Social Capital. These new resources and partnerships will enable Aclima to further expand its connected sensor networks to cover millions more people in many more places.
