About the CO2 Emission Warning Sign color filled icon

A rounded triangular hazard sign carries the chemical formula CO2 in heavy lettering with a subscript two, set on a bright warning field inside a bold black border. It signals carbon dioxide exposure, gas build-up and greenhouse emissions, making it suitable for workplace safety signage, industrial gas detector interfaces, sustainability and ESG reports, climate campaign slides and environmental compliance documents.

The equilateral triangle with softened corners follows standard hazard-sign geometry, and the lettering is centered in the lower two-thirds where the shape is widest, keeping the formula readable. It pairs with other hazard triangles, gas cylinder and carbon footprint icons. Use at 32px or larger so the small subscript stays legible.

This is the colour filled version of the co2 emission warning sign icon: a flat, solid-colour shape that stands out in dashboards, marketing pages and app tiles where the icon needs to carry colour meaning.
