A constituent has raised the issue of the impact of fireworks on air pollution. What data have you collected on the impact of fireworks on air pollution across the year as well as the impact of the GLA fireworks each New Year’s Eve?

As fireworks events are a rare occurrence, their impact is extremely short lived, localised and minimal. We do not hold specific air quality data on the impact of firework events.

The GLA’s events are managed and delivered in accordance with our GLA Event Sustainability Policy [link] which includes air quality, carbon, energy efficiency, waste reduction, and considers the environmental impacts from transport.

The New Year Eve celebrations this year were quite different to past New Year Eve events. Data provided by the event organiser showed that this resulted in a reduction of combustion by-products (including NOx, CO2, SO2 and other solids such as aluminium oxide) of 69% when compared to the 2019 New Year Eve celebrations. We are committed to continuing to improve our New Year Eve events and reducing our environmental impact.
