megaton

[′meg·ə‚tən]
(physics)
The energy released by 1,000,000 metric tons of chemical high explosive calculated at a rate of 1000 calories per gram, or a total of 4.18 × 1015 joules; used principally in expressing the energy released by a nuclear bomb. Abbreviated MT.

For example, the model assumes that by the year 2020, the following will occur: despite the absence of federal regulation, passenger and freight transportation efficiency, along with some questionably large gains in automobile efficiency, will reduce emissions by thirty-five megatonnes from a business-as-usual forecast; (22) the East-West transmission grid will be expanded to transport clean power across Canada, (23) a project that will require considerable inter-jurisdictional cooperation; contributions into a "Technology Fund" will somehow generate twenty megatonnes of emission reduction; (24) and offsets from the agricultural and forestry sectors--greenhouse gas--reducing actions that would not have otherwise been undertaken--will produce almost fifty-five megatonnes of reduction.
