Department of Climate, Energy and the Environment

Could you please provide me with all evidence that you have relied upon to inform your Climate Action Plan 2021 that CO2 (carbon dioxide) is the leading cause of global warming/climate change. Could you also provide me with the same information for methane and nitrogen. Can you also confirm your understanding of the percentage that CO2, methane and nitrogen make up of all 'greenhouse gases' and your calculations as to how a reduction in these percentages will make a difference? Can you also confirm what 'greenhouse gases' you are referring to in the Climate Action Plan and whether you are including water vapour (95% of all greenhouse gases) in your 51% reduction target? Could you also provide me with details of all or any geo-engineering activities being undertaken over Irish airspace either past, present or planned, including weather modification activities. Should such activities exist, please provide me with the safety studies relating to same.
