Crushed basalt was spread yearly on a maize–soybean farm for four years; carbon removal was estimated from calcium and magnesium lost from the rock (not measured directly), and crop yields rose about 12–16% with no rise in trace metals in grain.
Built / tested: field-scale trial plots

Deemer and colleagues estimated reservoir water surfaces emit about 0.8 Pg CO2-equivalent per year, mostly as methane, with reservoir productivity the best predictor of emissions.

Kharecha and Hansen calculated that global nuclear power has prevented an average of 1.84 million air-pollution deaths and 64 Gt CO2-eq of emissions compared with fossil fuels.

Howarth and colleagues estimated 3.6–7.9% of methane from shale-gas wells escapes to the atmosphere over a well's lifetime, giving shale gas a larger 20-year greenhouse footprint than conventional gas, oil or coal. Cathles and colleagues (2012, doi:10.1007/s10584-011-0333-0) argued these fugitive-emission estimates were significantly overestimated.
