When evaluating the environmental impact of sculptures, the carbon footprint of materials plays a crucial role. Metal sculptures, often made from steel, bronze, or aluminum, have a significant carbon footprint due to energy-intensive mining, refining, and fabrication processes. However, metals like aluminum can be recycled indefinitely, reducing long-term environmental impact.

Comparatively, sculptures made from wood or stone may seem more sustainable, but deforestation and quarrying also carry ecological costs. Plastics and resins, while lightweight, rely on fossil fuels and often end up as non-biodegradable waste.

For eco-conscious artists, reclaimed metals or recycled materials offer a lower-carbon alternative. Ultimately, the sustainability of a sculpture depends on material sourcing, production methods, and lifespan—making metal a viable option when responsibly managed.
