Climate Change Management

Question 1

2015 Paris agreement

Answer 1

limit global temperature increases

Question 2

Carbon capture and storage

Answer 2

catch 90% of emissions, which could cut global carbon emissions by 19%
CO2 can be stored directly in sedimentary rocks by turning it into a high pressure liquid (supercritical
C02) and injecting it into the rock

Question 3

Change of land use

Answer 3

Grasslands are able to sequester approximately 810 million tones of CO2 globally
Avoiding overgrazing by livestock
Adding manures and organic material rather than artificial fertilisers
Stock and crop rotation to allow grassland and soil to recover
Carbon farming - one type of crop is replaced by another that absorbs more CO2 from the atmosphere - legumes and grasses
Irrigation and water management improves plant productivity and prevents soil leaching
Reduced ploughing (zero tillage) of fields avoids rapid decline of soil quality and carbon release
Polyculture, where growing annual crops in between trees helps protect soils from erosion and boost stores of carbon

Question 4

Kyoto Protocol

Answer 4

legally binding reduction of CO2 emissions by many high-income countries aim was to cut global greenhouse gas
emissions by 5% from 1990 levels by 2012
Many newly emerging countries (China, India etc.) were exempt
Introduced carbon credit trading to control total increase of pollution collectively

Question 5

Clean development mechanism

Answer 5

Clean Development Mechanism is where HICs invest in emission-reducing projects in LICs or NEEs
Investments in projects such as forest conservation, peat and wetland restoration offset expensive emission-reduction projects in HICs

Question 6

UK

Answer 6

Net 0 carbon emissions by 2050
