Globally, there are millions of kilometres of drainage ditches which have the potential to emit the powerful greenhouse gas methane (CH 4 ), but these emissions are not reported in budgets of inland waters or drained lands. Here, we synthesise data to show that ditches spanning a global latitudinal gradient and across different land uses emit large quantities of CH 4 to the atmosphere. Area-specific emissions are comparable to those from lakes, streams, reservoirs, and wetlands. While it is generally assumed that drainage negates terrestrial CH 4 emissions, we find that CH 4 emissions from ditches can, on average, offset ∼10% of this reduction. Using global areas of drained land we show that ditches contribute 3.5 Tg CH 4 yr −1 (0.6–10.5 Tg CH 4 yr −1 ); equivalent to 0.2%–3% of global anthropogenic CH 4 emissions. A positive relationship between CH 4 emissions and temperature was found, and emissions were highest from eutrophic ditches. We advocate the inclusion of ditch emissions in national GHG inventories, as neglecting them can lead to incorrect conclusions concerning the impact of drainage-based land management on CH 4 budgets
