About EmisiMap

EmisiMap is an interactive platform designed to visualize air pollution sources using processed satellite imagery, revealing the specific emitters responsible for poor air quality.

Unlike traditional ground-based monitoring, satellite-based earth observation provides objective, non-intrusive, and consistent environmental data with wide spatial and temporal coverage. By leveraging advanced technology—especially the TROPOMI instrument on the Sentinel-5P satellite—we can detect tropospheric pollution columns even in remote areas without ground sensors.

Our goal is to offer a clear and intuitive way to link energy infrastructure and environmental data, making invisible pollution visible for everyone.

This project is built using Next.js, React, and Leaflet, demonstrating modern web development practices for environmental data visualization.

How It Works

Emisi Map processes geospatial data to identify "hotspots" of NOx and other pollutants. By overlaying this data with locations of known energy infrastructure—such as coal-fired power plants, smelters, and industrial parks—we can attribute emissions to specific sources, allowing users to see not just where pollution is, but who or what is likely generating it.

About Us

This platform is an initiative by the Centre for Research on Energy and Clean Air (CREA). CREA is an independent research organization focused on revealing the trends, causes, and health impacts, as well as the solutions to air pollution. We use scientific data, research, and evidence to support the efforts of governments, companies, and campaigning organizations worldwide in their efforts to move towards clean energy and clean air.
