Ireland's carbon emissions per person are 56% higher than the European Union average.
Figures from the CSO show they have been at similar levels for the past number of years.
Throughout Europe, Ireland's carbon emissions per person are the second worst - only behind Luxembourg - a country of over 600,000 people and around the size of Roscommon.
The figures show since the 1990s agriculture has consistently accounted for around a third of emissions - something the Government plan to bring down to a quarter.
Since 1961 the country's average temperature was at its highest in 2021 - and with many temperature records broken so far in 2022, it could be surpassed again.
When comparing EU countries Ireland has the third lowest forest cover at just 11%, compared to 66% for Finland.
Ireland also has the second lowest proportion of agricultural land used for organic purposes at just 1.5% - whereas in Austria it's around a quarter.
And in 2020, 42% of electricity generation in Ireland was from renewable sources.
