  1. According to the GHG Protocol, which 'Scope' encompasses indirect emissions from purchased electricity consumed by a reporting organization?

    Answer: Scope 2

    Scope 2 covers indirect GHG emissions from the generation of purchased electricity, heat, steam, or cooling consumed by the reporting organization.

  2. What is the 100-year global warming potential (GWP) of methane (CH4) according to the IPCC Fifth Assessment Report?

    Answer: 28

    The IPCC AR5 assigns methane a 100-year GWP of 28, making it significantly more potent than CO2 but less potent than nitrous oxide over that timeframe.

  3. Which international agreement established the first legally binding greenhouse gas emission reduction targets for developed countries during its 2008–2012 commitment period?

    Answer: Kyoto Protocol

    The Kyoto Protocol (1997) set the first legally binding GHG reduction commitments for Annex I (developed) nations during its initial 2008–2012 commitment period.

  4. Under the Global Protocol for Community-Scale Greenhouse Gas Inventories (GPC), emissions from on-road vehicles and transit systems are categorized under which sector?

    Answer: Transportation

    The GPC framework categorizes emissions from on-road vehicles, railways, waterborne navigation, and aviation under the Transportation sector.

  5. The Paris Agreement established a long-term goal to hold the global average temperature increase to well below how many degrees Celsius above pre-industrial levels?

    Answer: 2.0°C

    Article 2 of the Paris Agreement commits parties to holding the global average temperature increase to well below 2°C above pre-industrial levels, while pursuing efforts to limit it to 1.5°C.

  6. According to EPA inventory data, which sector has been the single largest source of greenhouse gas emissions in the United States since approximately 2016?

    Answer: Transportation

    Transportation surpassed electric power generation around 2016 and has since been the largest U.S. GHG source, accounting for approximately 28% of total emissions.

  7. In the context of climate change mitigation, what does 'carbon sequestration' refer to?

    Answer: The long-term capture and storage of atmospheric CO2

    Carbon sequestration refers to the long-term removal and storage of atmospheric carbon dioxide through biological processes (forests, soils) or geological storage (carbon capture and storage).
