The government in Northern Ireland has highlighted the importance of reducing emissions from residential properties, something that might be achieved by investing in green home improvements.
Minister for social development Margaret Ritchie and Irish environment minister John Gormley visited an energy efficient home in Holywood this week.
Ms Richie said the two ministers would share ideas on best practice with regards to green home improvements and eco-friendly developments.
The Irish minister commented: "I believe that we must continue to seek to reduce emissions from the residential sector."
He said a "key challenge" in the coming years would be bringing high energy efficiency levels into the mainstream residential sector.
According to the Energy Saving Trust in the UK, one home improvement that can reduce the carbon footprint of a property is installing double glazing, along with loft and cavity wall insulation.
