mitigation Flashcards
what is mitigation
action taken to reduce the sources and enhance the sinks of greenhouse gases to reduce long term risks of climate change on human life.
glob/region/individual eg
paris agreement
gov say reduce fossil fuel by in renewables
use less cars
insulate home
8 strategies
change rural use
-grassland
-crops
-forested land
aviation
modify photosynthesis
modify deforestation
gov policies
modify industrial combustion
grassland
potential mitigation 800 tonnes co2 in soil
avoid over grazing
-less compact soil, less vegetation eaten,less methane
add manure
more growth
more sequestered
reveg
mor sequestered
irrigation management
more moisture
more growth
more sequestered
crops
mulching
keep crop remains so more carbon to soil
reduced tillage
less soil turnover
less react oxygen
carbon stay in soil
animal manure
rotate crops
fallow year to restore nutrients
healthy soil
more growth
variety crop
less monoculture
more produced
forested land
protect remaining
afforest
more trees
more sequested
tree in cropland
more carbon taken in
carbon to soil
aviation pracitives
2013 - 3bill, 700mill tonnes co2
2019 - 39 bill
inc 120% emissons
fill flight so more efficent - less carbon per head
aovoid air queueing
inc engine efficiency
aerodynamics
modify photosynth
plant higher density trees
sequester more
selective logging to give space for growth
modify deforest
buy wood from certified councils
carbon offset payments
gov policies
brazil landowners preserve 80% virgin forest
grants for agricultural zones where deforest already happenign not given
brazil reduced by 70%
paris climate summit
limit to emissions
modify combustion
capture 90% from industry
store in depleted oil field under sea
very spenny
N sea new liscense for oil so need think about capture
cop21
all nations agree take action
share responsibility
nationally determined contributions - plants reduce emissions
devolped to help developing
review every 5yrs
UNFCCC
rio earth summit 92’
stabilise greenouse gas conc
framework for futureky
kyoto protocol
2005
developed to reduce emisiions
montreal project
phase out use ozone depleting substances and CFCs
