The bigger question not addressed is why this - "cardinal and bishop members, who frequently travel to Rome to help the offices in their work."  Where is the heavy lifting here?  Again, all of this bureaucratic claptrap can be handled by technology.  Despite Francis' concern for the planet, he isn't reducing the carbon footprint of clergy traveling to the Vatican continually.
Better the travel funds be diverted to the poor.  No seriousness about the poor, the climate.
Business as unimaginative as usual!
