A preliminary survey of household and personal carbon dioxide emissions in Ireland.
A model specifically designed for Ireland was used to measure CO(2)e emissions (CO(2), CH(4) and N(2)O) from Irish households for the first time. A total of 103 Irish households with occupancy rates varying between 1 and 6 (mean 2.9) were surveyed. The average annual household emission was found to be 16.55 t CO(2)e y(-1), which is equivalent to an average personal emission of 5.70 t CO(2)e Ca(-1) y(-1) comprising 42.2% related to home energy use, 35.1% to transport, 20.6% to air travel and other fuel intensive leisure activities, and just 2.1% associated with household waste disposal. Air travel accounts for an average personal emission of 1.152 t CO(2)e Ca(-1) y(-1), although this is highest in single and two person households at 1.693 and 2.227 t CO(2)e Ca(-1) y(-1) respectively. Household energy consumption becomes more efficient when occupancy rate increases. The most energy efficient homes in the survey were terraced with a natural gas heating systems. The least efficient were detached house with oil fuelled heating system.
