COVID-19 Release Information

The COVID-19 pandemic in 2020 and 2021 may have had an impact on the trend in some of the indicators (such as emissions to air, transport and energy) in this publication.

Key Findings

  • The highest average annual temperature in Ireland over the 1961-2022 period occurred in 2022 at 10.61Celsius (see Figure 4.4).

  • Emissions of greenhouse gases by the EU27 fell by 29% from 4.9 billion tonnes of CO2 equivalent in 1990 to 3.5 billion tonnes in 2021 (see Table 1.4).

  • The percentage of dwellings completed between 2020 and 2022 in Ireland with an A energy rating was 99% (see Table 2.7).

  • Ireland had the second highest emissions of greenhouse gases per capita in the EU27 in 2021 at 12.3 tonnes of CO2 equivalent (see Figure 4.2).

  • In 2022, 1% of urban waste water received no treatment compared with 46% in 1997 (See Table 5.3 and Figure 5.3).

  •  Renewable energy accounted for 39% of electricity generation in Ireland in 2022 up from 5% in 1990 (see Table 7.3).

  • The proportion of municipal waste sent to landfill in Ireland fell from 74% in 2001 to 16% in 2021 (see Table 9.2).

Statistician's Comment

The Central Statistics Office (CSO) has today (14 December 2023) released the Environmental Indicators Ireland Report 2023

Commenting on the publication Reamonn McKeever, Statistician in the Environment and Climate Division of the CSO said: “Today, we publish the CSO’s 2023 report on Environmental Indicators Ireland. This publication covers 70 indicators over 10 themes.

In terms of global warming, 2015-2019 were the five warmest years on record between 1850 and 2019 as measured by global mean near surface temperature deviations compared with pre-industrial 1850-1899 levels.

The highest average annual temperature in Ireland over the 1961-2022 period occurred in 2022 at 10.61o Celsius.

Emissions of greenhouse gases by the EU27 fell by 29% from 4.9 billion tonnes of CO2 equivalent in 1990 to 3.5 billion tonnes in 2021. Emissions in Ireland rose by 9.2% from 55.6 million tonnes of CO2 equivalent in 1990 to 60.8 million tonnes in 2022.

Other findings include:

  • Environmental subsides in Ireland were €1.6 billion in 2022, up 7% from the 2021 figure of €1.5 billion.
  • Pollution and Resource taxes contributed 0.4% of total environment taxes in 2022.
  • Gross output in the environment goods and services sector comprised 3.8% of modified Gross National Income in 2020.
  • River water quality: The percentage of rivers and streams in Ireland with high water quality decreased from 27% in 1987-1990 to 16% in 2019-2021.
  • Forestry accounted for 11.4% of Ireland’s total land area in 2020, the third lowest among EU27 Member States after Malta and the Netherlands.
  • The number of new dwelling completions in Ireland increased by 45% from 20,546 units in 2021 to 29,751 units in 2022.
  • Renewable energy accounted for 39% of electricity generation in Ireland in 2022.
  • Transport: In 2022, 15% of all new cars licensed for the first time were electric, up from 0.4% in 2015.”

Editor's Note

The Environmental Indicators Report for Ireland was first published in 2012 originally on a biennial basis and from 2018 on an annual basis. This is the ninth edition of Environmental Indicators Ireland.

A total of 70 indicators covering 10 domains have been selected for this publication Many of the indicators are presented in a time-series format for Ireland, while the international context is shown by comparing Ireland with other countries and world regions for the latest year for which data are available.

The environment area is wide-ranging and the 10 domains cover the global context, environmental economy, air, greenhouse gases and climate change, water, land use, energy, transport, waste and biodiversity.
