Study shows how rocket launches pollute the atmosphere

In a high-growth scenario for the space industry, there could be as many as 2,000 launches per year, which her modeling shows could result in about 3 percent ozone loss, equal to the atmospheric impacts of a bad wildfire season in Australia. She said most of the damage comes from chlorine-rich solid rocket fuels and black carbon in the plumes. The black carbon could also warm parts of the stratosphere by about half-a-degree Celsius as it absorbs sunlight.
