EasyJet to offset carbon emissions from all its flights

Airline will also relaunch its package holiday business in wake of Thomas Cook collapse

EasyJet is set to become the world's first major airline to operate net-zero carbon flights across its entire network, after announcing it would offset all jet fuel emissions.

The British budget airline said it would start offsetting all flights from Tuesday, which it said would cost about 25m in the next financial year through schemes to plant trees or avoid the release of additional carbon dioxide.
