Delivery company DPD Ireland is to create 150 jobs over the next year, as it projects 20% growth in 2019.
DPD had a turnover of €91.5m last year - and delivered 20 million parcels. This year it expects that figure to rise to 24 million.
It has also announced a €3.2m investment in the rollout of a fleet of electric vehicles, which will cover 15 of its Dublin delivery routes.
The courier company has 10 electric vehicles on the road today - with 15 more ordered - as part of its aim to be carbon neutral.
"The network covers every delivery point in Ireland and we have 1,100 vehicles a day in every county," said Des Travers, CEO of DPD Ireland. "This is the beginning of a new journey for us into electric, carbon neutral delivery points and we've launched it into the Dublin city area to get ourselves started."
The company hopes to extend the fleet further, however Mr Travers said that current technology meant electric vehicles were only suited for deliveries in urban areas.
"We'd love to be fully electric but at the moment the technology doesn't support us," he said.
"We are okay to go from our East Wall depot to, say, Donnybrook because of the capacity of the batteries - but, for instance, in west Cork it would be impossible to use electric vehicles at the moment."
However he said the technology is moving on, so this issue is something he hopes will be addressed over time.
Mr Travers also said that he sees this as being something that the entire delivery business will move towards over time, as costs and range issues reduce.
He said it is part of a broader strategy by the company to be carbon neutral, which has involved things like more efficient depots, a switch to recyclable packaging and the use of carbon credits to offset its remaining emissions.
The company has grown rapidly in recent years and the majority of the 150 staff it plans to add this year will be aimed at serving that increased demand.
Mr Travers said that is primarily coming from ecommerce, as more people move their shopping habits online.
"The internet expansion for the last ten years is not fresh or new news, and we're seen as a final mile delivery company for internet users," he said. "Our base is growing all the time and we're delighted that our growth over the past two years has been double digit."
However DPD Ireland is up against a number of significant competitors - from global players like DHL to local incumbent An Post.
Its recent brand refresh saw it redouble its efforts around parcel deliveries, which Mr Travers said is a threat to his business.
"We respect all of our competitors in the marketplace," he said. "An Post is a very good company and we're watching what they're doing and likewise I'd say they're watching what we're doing."
