While pollution has dipped, greenhouse gases keep accumulating in the atmosphere, locking in future decades of climate disruption and extreme weather.
As for who's chiefly responsible for the gap, it's the global rich, the report says.
Just 10% of the world's population emits nearly half of the world's carbon pollution.
That translates into a reduction of 97% in carbon emissions for the wealthiest people.
"Rich countries tend to be cleaner on other things, have cleaner water and air, but that's not true for CO2.".
Carbon emissions are effectively embedded across much of the global economy, so consuming in general is akin to polluting.
"It's the responsibility of policymakers to support alternatives that give people the goods they need without destroying the climate.". »
