preventing climate change Flashcards
which is the most polluting fossils fuel
coal is the most polluting out of the fossils fuels
what percent does china, the USA and India use coal to get energy from
China - 80%
USA - 50%
India - 70%
how does carbon capture work
carbon gas is compressed and transported by pipeline to injection well.,
it is injected as a liquid into the ground to be stored in suitable geological reservoirs
what is CCS
Carbon capture and storage uses technology to capture co2 produced from fossil fuels in electricity generation and industrial process.
it captures up to 90% of carbon
planting trees
trees act like carbon sinks removing co2 from the atmosphere by photosynthesis
absorb moisture into atmosphere
cooling affect produces more cloud blocking the sun’s radiation
why is plating trees good
well established in many parts of the world
plantation forests can absorb co2 at faster rates than natural forest
alternative energy sources
solar wind tides hydro-electricity nuclear power
what percent does The UK want to produce non co2 energy sources
15%
what can burning fossil fuels do
fuel for vehicles
electricity
power industry
what does fossils fuels contributes
it contributes to 87% of human co2 emisions
what do the rest of man made co2 emissions come from
4% industrial processes
9% deforestions
what is good about other energy sources
can latst forever
do not emit as much co2
2005 Kyoto protocol
first international agreements became law
over 170 countries agreed
only USA and Australia did not sign
reduce emissions to 5.2
Copenhagen 2009
world leader agreed to financially help developing countries to reduce their carbon emissions
- no legal binding
2015 Paris agreement
195 countries agreed to universally and binding law global climate deal
to peak greenhouse gases emissions as soon as possible and achieve a balance of sources and sinks of greenhouse gases in the second half this century
