Answer
To find the value of X, we need to add up the known percentages from the pie chart for other sectors:
Agriculture: 34%
Residential: 17%
Waste: 17%
Energy Industries: 2%
Combining these:
34+17+17+2=70
The total percentage of emissions must equal 100%, so:
X=100−70=30
Therefore, the percentage share of Ireland's greenhouse gas emissions that was generated by transport is 30%.

Answer
One effective way to reduce greenhouse gas emissions from new houses is to install solar panels on the roofs.
Solar panels capture sunlight and convert it into electricity, significantly lowering reliance on fossil fuels. The electricity generated can be used directly in the house or stored in batteries for later use. By utilizing renewable energy sources like solar, new houses can contribute to decreased greenhouse gas emissions while promoting sustainability.
