Carbon savings comes not only from new technology, but also from new systems.

A recent study on bus transportation in Mexico proposes a more holistic way of estimating CO2 reduction. It views transportation as a service – moving people from point A to point B – rather than isolating different forms of transportation. When considering the replacement of a private car by public transport, the system-wide savings can be very meaningful. The calculation of the CO2 reduction along different commuting corridors evaluated service during peak hours and the total demand of the route. The bus lines maintain an average occupancy of 113 users for a complete service (from terminal to terminal), i.e. 70.6% of their capacity while in an average car only utilizes a third of its seats. From the daily demand of users who stopped using their car, more than 17 tons of CO2 are reduced for each kilometer traveled! A narrower calculation misses this fundamental point. For example, the reduction of CO2 by a 20% more efficient bus, reduces about 300 grams per kilometer.
