• Quotation from source:

The emissions of the richest 1 per cent of the global population account for more than twice the combined share of the poorest 50 per cent. Compliance with the 1.5°C goal of the Paris Agreement will require reducing consumption emissions to a per capita lifestyle footprint of around 2–2.5 tCO2e by 2030. This means that the richest 1 per cent would need to reduce their current emissions by at least a factor of 30, while per capita emissions of the poorest 50 per cent could increase by around three times their current levels on average (figure ES.8).

• Suggested caption:

The emissions of the richest 1% of the global population account for more than twice the combined share of the poorest 50%. Compliance with the 1.5°C goal of the Paris Agreement would require the richest 1% to reduce their current emissions by at least a factor of 30, while per-person emissions of the poorest 50% could increase by a factor of about 3.

• Calculations are based on data from Figure ES.8 from source:

Earners category — % of population — % of Emissions — Emissions per person

top 1% _ 1 _ 15 _ 15.00

top 10% _ 10 _ 48 _ 4.80

Middle 40% _ 40 _ 44 _ 1.10

Bottom 50% _ 50 _ 7 _ 0.14

Square roots of right two columns (for calculating radius of circles):

% of Emissions — Emissions per person

3.873 _ 3.873

6.928 _ 2.191

6.633 _ 1.049

2.646 _ 0.374

Normalized so smallest value = 1.00. These are the values literally used in the SVG code for circles' radii.

% of Emissions — Emissions per person

1.464 _ 10.351

2.619 _ 5.855

2.507 _ 2.803

1.000 _ 1.000
