Charity says world’s fast-shrinking carbon budget should be used to improve lot of poorest

The wealthiest 1% of the world’s population were responsible for the emission of more than twice as much carbon dioxide as the poorer half of the world from 1990 to 2015, according to new research.

Carbon dioxide emissions rose by 60% over the 25-year period, but the increase in emissions from the richest 1% was three times greater than the increase in emissions from the poorest half.
