Q

Paris Agreement: Mitigation

A
  • Binding commitments to prepare, communicate and maintain a nationally determined contribution (NDC) and to pursue domestic measures to achieve them.
  • Parties shall communicate their NDCs every 5 years. To set a firm foundation for higher ambition, each successive NDC will represent a progression beyond the previous one and reflect the highest possible ambition

Q

Mitigation measures

A
  • Change in energy supply
    – Decarbonizing → low carbon energy sources (renewable, nuclear energy???)
    – Increasing energy efficiency, replace coal fire plants by natural gas combined cycle
    plants or combined heat and power plants
  • Changes in transport, e.g. infrastructure, urban planning, low carbon fuels
  • Agriculture/Forestry and other land use (currently emit ~10 20 GtCO 2 per year)
    – Afforestration , sustainable management of forests
    – Cropland management, restoration of organic soils
  • Climate engineering/geoengineering (e.g. CO 2 removal, solar radiation management)
  • Behavioral changes ( mobility, energy use in households, food)

Q

Mitigation measures, policies and institutions

A
  • Changes in investment patterns
    – declined investments in conventional fuel technologies
    – increased investment in low carbon electricity supply, transport, buildings, industry
  • Regulatory approaches (e.g. energy efficiency standards) and information measures (e.g. labelling)
    – Often environmentally effective; BUT, also it is generally agreed, that rebound effects
    exist (but magnitude is unclear)
  • Cap and trade systems for GHGs (emission trading)
  • Technology policy complements policies
    – Technology push: e.g. by R&D
    – Demand pull: e.g. by public procurement
  • Tax based policies specifically aimed at reducing GHG emissions
    – Fuel taxes
  • Reduction of subsidies for GHG related activities in various sectors
    – Removal of subsidies for fossil fuels

Q

Paris Agreement: Adaptation

A
  • global goal of enhancing adaptive capacity, strengthening resilience and reducing vulnerability to climate change in the context of the 2/1.5C goal
  • All Parties should engage in adaptation, incl. by formulating and implementing National Adaptation Plans, and should submit and periodically update an adaptation communication describing their priorities, needs, plans, actions.
  • The adaptation efforts of developing countries should be recognized

Q

Adaptation measures

A
  • Engineered and built environment options:
    – Coastal protection, shelters, storm management, road infrastructure
  • Heat resistant road materials, lighter road pavement, storm water systems

*Technological options
– New crop and animal variety, water saving technologies, early warning systems

  • Ecosystem based options
    – Soil conservation, afforestation, green infrastructure (e.g. green roofs), gene banks
  • Services
    – Food banks, essential public health services, enhanced medical services
  • Economic options
    – Payment for ecosystem services, microfinancing, disaster funds
  • Laws and regulations
    – Building standards, laws to support disaster risk assessment, fishing quotas
  • National and government policies and programs
    – National, regional, sub national and local adaptation plans
    – Urban upgrading programs, e.g. improved housing and access to social support services
    –> Governments start to develop adaptation plans and policies to integrate climate change considerations in broader development plans, e.g. Europe: coastal and water management, Africa disaster risk management, Asia early warning system
  • Educational options
    – Awareness rising & integration into education, sharing indigenous, traditional and local knowledge
  • Behavioral options
    – Evacuation planning, migration, changed cropping practices

Q

Challenges of current adaptation strategies

A
  • Progress in most countries regarding efficient strategies is very slow
    – e.g. changes in farming practices known for many years, but barley applied
  • Most vulnerable people are often not adequately considered
    – e.g. insurance for extreme weather events is very expensive
  • Many measures are very expensive
    – e.g. resettlement of a water treatment facility
  • Funding is not sufficient, especially for poor countries
    – e.g. 100 billion USD per year through 2025 financial commitment of developed countries for developing countries not yet met (83.3 billion USD in 2020)
  • Especially in already poor regions, many other issues occur next to climate change which have to be tackled first
    – e.g. Malaria in Africa or political unrest

Q

Climate Finance

A
  • Local, national or transnational financing from
    public, private and alternative sources
  • To support mitigation and adaptation actions
  • Kyoto Protocol and the Paris Agreement call for
    financial assistance from Parties with more
    financial resources to those that are less endowed
    and more vulnerable
    –> UNFCCC Adaption Fund (AF), set up in 2007 as part of Kyoto, continued under Paris Agreement, partically funded by the CDM project activities

Q

Green climate fund (GCF)

A
  • Established in 2010 by 194 countries party to the UNFCCC Framework
    – Kept under Paris Agreement
  • For mitigation and adaptation projects
    – 20 9 projects
    – 666 million people with increased resilience
    – 2.4 billion tonnes CO2 eq avoided

Q

Possible Forms of Carbon Compensation

A

Emission Reductions, e.g.:
- Renewable Energy
- Waste reduction

CO2 Removal/ Negative emission technologies (NETS), e.g.:
- Bioengery with carbon capture and stoarge (BECCS)
- Direct Air carbon (DAC) capture storage

CO2 Removal vie Geoengineering, e.g.:
- Ocean fertilization
- Wetlands
- Enhance weathering

Q

Renewable Energy Projects as Carbon Offsets

A
  • Renewable Energy (RE) projects are an accepted offsetting mechanism in all three major o ffsetting programs : Clean Development Mechanism (CDM), Verified Carbon Standard (VCS), Gold Standard (GS)
  • Projects aim to foster a sustainable development of the energy system in Non Annex I countries = developing countries
  • RE project needs to be deemed as „additional“ by the CDM executive board

Q

CER calculation for renewable energy projects

A
  • The amount of certified emission reductions (CERs) issued for RE projects is calculated according to the theoretically saved emissions of the project
  • The emission baseline is determined by the emissions that would occur by providing the same amount of electricity as supplied by the RE project
  • Only use phase is considered for both renewable energy projects and fossil fuel baseline scenario –> thats why RE (e.g. PV) is emission free
17
Q

Challenges RE

A
  • Market effects
  • Low additionality
  • Emission calculation
    based on use phase
18
Q

BECCS

A

Negative emissions technology (NET) and part of geoengineering proposals
to keep the global temperature under 2 C

19
Q

BECCS Strengths and weaknesses

A

Strengths
* NET
* Existing technology
* Renewable source
* Decarbonization
* Energy security
* Permanent sequestration

Weaknesses
* Requires significant inputs of land,
nitrogen, phosphorus and water
* High costs for capture and storage and also biomass growth
* Many trade offs and uncertainties

–> BECCs deployment should be limited only to circumstances where is it proven to be beneficial

20
Q

Direct Air Capture (DAC)

A
  • Direct Air Capture (DAC) is another possible negative emission technology (NET)
  • Direct Air Capture (DAC) has the potential to remove 0.5 5 Gt CO2/year by 2100, limited by technology readiness, upscaling capabilities and costs
    – two basic concepts: either DAC high temp (absorption and calcination) or DAC low temp (absorption and desorption)
21
Q

Options Carbon Capture

A
  • Closed carbon cycle via biomass -> „carbon neutral“
  • Closed carbon cycle via DAC carbon usage -> „carbon neutral“
  • Carbon offsetting via biomass, DAC carbon storage -> „carbon negative“
  • Carbon offsetting via fossils, DAC carbon storage -> „carbon neutral“

–> DAC plants indepent from CO2 source –> flexibale carbon offsetting

22
Q

Strengths and weaknesses DAC

A

Strengths
– scalable technical plants for CO2 removal with low area demand
– can be built at places independent from CO2 source to create carbon offsets
– predictable CO2 removal price and capacity
– important enabler for ‘carbon neutral’ synthetic fuels
– low energy demand when integrated in excising plants with heat sources

Weaknesses
– currently in research and development phase
– many uncertainties due to development status, especially the costs
– uncertainties for the water demand
– requires the availability for cheap renewable energy to run at full load
– possible material/waste and chemicals implications to be assessed  LCA topic
