Rising ammonia levels in West Africa linked to biomass burning

·         The Protocol sets national emission ceilings for 2010 up to 2020 for four pollutants: sulphur (SO2), nitrogen oxides (NOx), volatile organic compounds (VOCs) and ammonia (NH3).

·         This protocol is also known as Muti-effect protocol.

·         These ceilings were negotiated on the basis of scientific assessments of pollution effects and abatement options.

·         Parties whose emissions have a a lot of severe environmental or health impact and whose emissions are comparatively cheap to reduce can need to create the largest cuts.

·         Currently, the protocol is under negotiation for a revised protocol.
