Aclima

Aclima

Measures air quality with network sensors

Overview

Aclima builds a hardware and software platform that measures air pollution and greenhouse gases at street level, using a network of roving sensors to collect billions of measurements and turn them into environmental intelligence for governments, businesses, and communities. How it works: sensors mounted on roving devices gather data on pollutants and emissions across different areas, which is then processed by Aclima’s software to produce actionable insights and maps for decision making. How it differs from competitors: Aclima operates a global, block-by-block sensing network rather than relying on sparse fixed stations, and it is organized as a Public Benefit Corporation focused on public health and clean air rather than purely profits. Its goal is to catalyze bold action to protect public health, reduce emissions, and ensure clean air for all.
