No evidence for substantial aerobic methane emission by terrestrial plants: a 13C-labelling approach
Author for correspondence:Tom A. Dueck
- • The results of a single publication stating that terrestrial plants emit methane has sparked a discussion in several scientific journals, but an independent test has not yet been performed.
- • Here it is shown, with the use of the stable isotope 13C and a laser-based measuring technique, that there is no evidence for substantial aerobic methane emission by terrestrial plants, maximally 0.3% (0.4 ng g−1 h−1) of the previously published values.
- • Data presented here indicate that the contribution of terrestrial plants to global methane emission is very small at best.
- • Therefore, a revision of carbon sequestration accounting practices based on the earlier reported contribution of methane from terrestrial vegetation is redundant.
