Facts about spray paint and its impact

Spray paint is widely used in art and creative expression, but it also has measurable environmental and health impacts. This page presents key facts based on scientific research and lifecycle thinking, helping artists better understand the materials they work with.

How environmental impact is measured

The environmental impact of spray paint is measured using Life Cycle Assessment (LCA), a scientific method that evaluates impacts across a product’s entire life cycle. Key areas are:

LCA is commonly used in environmental research and product design to quantify impacts such as greenhouse gas emissions (CO₂-eq).

Environmental impact of a spray paint can

A single spray paint can has an estimated climate impact of approximately ~1.5 to ~3.3 kg CO₂-eq, depending on factors such as formulation, solvents and propellant that are used, and packaging.

What contributes most to the impact

Waste and end-of-life

Empty spray cans are considered hazardous waste unless fully depressurised and properly collected. Recycling rates vary widely by country and infrastructure.

Health and exposure

Spray paint contains substances that may affect your health negatively, particularly through inhalation in poorly ventilated spaces.
