Poverty Eradication in a Carbon Constrained World
In this paper for
Nature Communications, Klaus Hubace, Giovanni Baiocchi, Kuishuang Feng, and Anand Patwardhan investigate potential consequences for climate targets of achieving poverty eradication. They find that moving people to an income above $1.9 purchasing power parity (PPP) a day does not jeopardize the climate target, even in the absence of climate policies, and with current technologies. Lifting people out of extreme poverty has relative little carbon implications with a projected increase of about 0.05 °C above the IPCC base run by the end of the 21st century. Given that the top ten percent of global income earners are responsible for 36 percent of the current carbon footprint of households, policy discourse should address income distribution and the carbon intensity of lifestyles.
