While newer diesel vehicles can be better than older cars for the environment, under certain conditions, such as short, slow speed journeys, as often found in London, they produce almost as much harmful NOx as new lorries . One potential measure to reduce the impact on this is the introduction of a diesel scrappage scheme, providing incentives to diesel car drivers (or older petrol vehicles) to switch to cleaner, low emissions vehicles or away from cars altogether.
This incentive could take a number of forms, such as discounts on new vehicles (as in a previous national government scrappage scheme), or another subsidy such as reduced car club membership.
What do you think? Do you currently drive a diesel vehicle, and if so, what would encourage you to switch? What would stop you from upgrading to a cleaner vehicle?
