Since 2006, WMO has published annual Greenhouse Gas Bulletins. These Bulletins report on the latest atmospheric abundances and rates of change for the main long-lived greenhouse gases (LLGHGs) – carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) – and provide a summary of contributions from other greenhouse gases.
