The impact of the use phase is completely indirect in relation to the industrial activity of Pirelli, there is no doubt that this is the phase that makes the greatest contribution by far during the tyre life cycle. The carbon and water impact varies from 75% to 90% of the total. This is due almost entirely to the power absorbed by the tyres, which deform by absorbing energy to guarantee road hold and braking performance. Rolling resistance is the characteristic that determines the level of energy absorption, and it precisely on this environmental performance that Pirelli is intensifying its own research. The reduction in rolling resistance entails lower fuel consumption by the vehicle system.
This consumption, which is realised with combustion in vehicle heat engines, combined with production of the fuels themselves, results in the impact of this phase in the life cycle.
