What does "CO₂-free" business travel mean?

The bahn.business programme for business customers enables CO₂-free travel with 100% renewable energy on DB's local and long-distance rail services within Germany.

This avoids direct carbon emissions. bahn.business offsets all indirect emissions, such as for the transfer of energy, via atmosfair after calculating the passenger kilometres travelled. Any emissions generated on non-electrified DB routes are also offset through bahn.business.
