mitigation strategies
reduce green house gases
international agreement and cooperation
united nation framework convention on climate change
key objective is to stabilise greenhouse gas emissions at a level that would prevent irreversible anthropogenic impacts. Provide enough time for ecosystem to adapt naturally to climate change
how does it work
puts greater responsibility on developed countries to lead the way
developed industrial countries produce the most greenhouse gas emissions so their suppose to cut the most emissions
funds and technologies are directed to climate action in developing countries
developed countries agree to share technology and provide financial support to developing countries for climate action
monitoring the progress of climate change policies
countries are required to regularly report on their climate change policies and green house emissions
limitations
its depends on countries on party commitment. Different countries have different priorities, commitment to act may vary. Its not legally enforced, so if a country does not do it the party can not enforce it
use of low carbon technologies
carbon capture
process of separating and capturing co2 from power plants and other industrial sources of emissions
utilization and storage
after co2 is captured, it's stored in oceans for a long time. Use co2 as material produce useful materials that can be sold for profit. eg cement. This allow it to not rch the atmosphere
limitations
it is expensive and requires public funding and subsidies for private research and development. There are concerns that stored carbon may leak out overtime
use of clean energy sources
clean energy comes from renewable source that do not pollute the atmosphere
solar energy
energy from sun is converted to thermal or electrical energy and is most clean and abundant energy
hydro-electric power
capture energy of moving water to generate electricity
geothermal
derived from heat in earth crust hot rock heats up ground water beneath the crust forming steam. This steam is harnessed to generate electricity
nuclear
splitting up radioactive atoms. this process generates heat. heat produces steam which is then harnessed to generate electricity. Compared to other sources of energy, nuclear energy is more stable in term of its supply
limitations
development and construction of renewable energy technology is expensive, so it depends on government policies and financial support to make renewable energy cost competitive
changes in consumption patterns
household consumption pattern of goods contributes to our carbon footprint as greenhouse gases are released during transportation and production of these goods
food choices
food production is responsible for more than a quarter of all greenhouse gases emissions. The type of food you eat have varied environmental impacts and greenhouse gases.
food waste
when food enters landfill and rots, it produces methane
how to solve
refusing single use plastic and using reusable daily plastic products and be informed on how to recycle different plastic products. This leads to less plastic waste going to incinerator, landfill or ocean
buying only what we need and repurpose food waste
ask manufacturers to use sustainable criteria to make clothing. Repair or upcycle old clothing and donate what you dont use. Buy only what you need. Opt for secondhand clothing when possible
eating less meat and more vegetables, buy local produce as it uses less transportation
use of plastics
chemicals sourced from fossil fuels are used to make plastics
plastics are recycled or incinerated
plastic biodegrade which occur over hundreds of years.
This leads to greenhouse gases being produced
fashion
high level of energy and water are required for the production of apparel
When consumers demand more frequent changes in design, production will increase which increase greenhouse gas emissions.
limitations
takes a long time to change people mindset and consumption patterns.
it depends whether the companies wants to change the resources used in production of goods which they probably do not want due to profit
enhance carbon sinks
protection of oceans and forest through managing land-use change
land use change accounts for 10 percent of global emissions.
how it works
reducing deforestation
deforestation leads to increase concentration of greenhouse gases due to less trees to absorb co2.
soil erosion as no more trees to anchor the soil, this leads to soil particles entering river and oceans which may suffocate coral and aquatic plats. If we reduce deforestation, it ensures that these stuff will not happen.
ways to reduce
buying wood that is certified as sustainable and banning illegal deforestation
restoring mangroves
mangroves are important coastal ecosystems due to their ability to absorb and store greenhouse gases in their soil 4x better than tropical forests, and filtering pollutants in rivers and preventing them from harming coral and aquatic species
restoring mangroves involves
planting mangrove seedling along coastal areas and creating the optimal conditions for mangrove to grow. Correcting the problems that cause mangrove loss.
limitations
difficult to reduce deforestation in growing economies due to competing land use for industries agriculture and urban spaces
protection of forests through forest regeneration
as trees grow they absorb and store carbon dioxide
how to regenerate forest
afforestation
planting new trees in area that previously did not have trees
reforestation
replanting trees in an area which had trees in the past
limitations
large scale afforestation can create competition for land which may lead to a limited land supply for agriculture. This would lead to increase food prices, threatening food security.
estimated that a large scale tree planting programme could take 50-100 years to have its full effect of removing 200b tonnes of carbon dioxide from the atmosphere
