Black carbon is a component of PM2.5 and a major contributor to climate change, heating the planet and altering clouds and rainfall patterns. Unlike CO2 (which can remain in the atmosphere and affect the climate for hundreds of years) black carbon only remains in the atmosphere for a few days or weeks. Reducing black carbon therefore provides rapid results against the climate crisis.
Diesel engines account for 25% of the world’s black carbon emissions so transporting more rubbish by river and road to feed the new incinerator is bad for the environment. Further information can be found here.
