Emissions from Rocket Launches

Welcome to our tracker of pollutant and greenhouse gas emissions from rocket launches. Select a time window of interest to visualise pollution on interactive plots, a 3D globe, or a 2D map. For more information, see the FAQs at the bottom of this page.

The time window is for 5 years (2020-2024). We need your support to add more years and track emissions immediately after launches. Please donate to or share our GoFundMe page!
