Exercise/Group discussion: 20 minutes

At the end of the session, learners will be able to:

Name the major non-CO2 GHGs, and describe whey
they are concerns

Recognize the major drivers of Non-CO2 GHGs
emissions

Explain how to measure/monitor Non-CO2 GHGs.

What are the most important GHGs in the Earth’s
atmosphere?

Which ones are primarily generated by human activities

Ozone and Non-methane volatile organic compounds
(NMVOCs) are other effective greenhouse gases

Non-methane volatile organic compounds (NMVOCs)
include CCl2F2, CHClF2, CF4 and C2F6

Formation of GHGs from precursor gases is considered
indirect emission (NOx, NH3, and CO are common
precursor gases)

N2O primarily emitted
during the processes of

Fertilizer additions
CH4 emitted through methanogenesis
CO2 + 8 H+
CH4 +2 H2O
The formation of methane by microbes
known as methanogens

In guts of humans and other animals,
especially ruminant animals (e.g.
cattle, sheep)

In anoxic environments, such as
wetlands and landfills/ manure
storage

Also produced in biomass burning


CH4 and N2O produced from
decomposition of manure

CH4 produced under anaerobic
conditions

N2O produced under aerobic
or mixed aerobic/anaerobic
conditions
Emissions of gas from manure
depends on storage system


When they constitute a significant proportion of
emissions from LULUCF, for example:

Slash and burn agriculture

Conversion of forest to pasture for livestock production

Application of synthetic fertilizers for crop production
Non-CO2 emissions are included in emission factors for
land use and land use change

The amount of N2O and CH4 emitted by fires is a function
of:

Area burned

Mass of fuel available for combustion in area

Proportion of fuel actually combusted – depends on size
and architecture of fuel load (twigs burn more efficiently
than large logs) moisture content and type of fires

Amount of GHGs emitted per unit fuel consumed
Emissions from Biomass = (1)*(2)*(3)*(4)*(5)
(1) Area burned *
(2) Biomass burned *
(3) combustion factor *
(4) Emission Factor for gas *
(5) GWP of gas

Using the emissions factors on the previous table and the
GWP values presented at the beginning of the lecture
calculate the size of the effect in the atmosphere from CO2,
CH4 and N2O emitted from burning 100 ha of tropical forest
after 10 years and after 100 years. Assume 85% of the
biomass is combusted

15 minutes

Nitrogen emissions are calculated as a function (fx) of the
amount of fertilizer applied

CH4 emissions from rice production are a function of:

Area cultivated

Cultivation period

Emission factor based on rice ecosystem type, flooding
pattern before and after cultivation, type and amount of
organic amendments, soil type, rice cultivar
General Equation:
CH4 emissions = CH4 EF * number of animals
CH4 emissions factors are calculated as a function of
livestock type, feed intake, and the conversion of feed
energy to methane
General Equation:
Emissions + EF * population of livestock
Tier 1 calculations use default values
Tier 2 includes more subclasses of livestock groups based on
management of both livestock and manure. For N2O feed type is
an addition consideration
