Are there eco-friendly fireworks and firecrackers?

Eco-friendly fireworks refer to those with formulas free of high-sulfur and heavy metal pollutants, significantly reducing combustion smoke, harmful gases, and inhalable particulate matter.

Compliant eco-friendly fireworks are currently available on the market. The new national standard Fireworks and Firecrackers - Safety and Quality, implemented on May 1, 2026, mandates that consumer-use fireworks upgrade to low-smoke, sulfur-free, low-noise, and low-particulate versions, phasing out traditional high-pollution black powder fireworks. Eco-friendly fireworks improve chemical formulations by removing high-pollution sulfur and heavy metals, using nitrocellulose and plant fiber propellants to significantly reduce SO2 and PM2.5 emissions, minimizing smoke, pungent odors, and residue, offering a balance of visual appeal and low pollution. Absolute zero-pollution or completely smokeless fireworks do not exist. Compliant eco-friendly fireworks on the market are 'low-smoke and low-pollution,' not 100% emission-free.

Eco-friendly fireworks only significantly reduce harmful pollutants and smoke volume. In windless, enclosed environments, burning still produces some particulates. Cold-light small fireworks have the lowest pollution, while large aerial eco-friendly shells still generate trace dust. For festivals, it is still recommended to choose open, ventilated areas and avoid large-scale concentrated burning.
