The Carbon Cycle01:14

The Carbon Cycle

36.9K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

Summary
This summary is machine-generated.

China's ICT sector shows greater carbon emission responsibility under consumption-based accounting (CBA) than other methods. Emission responsibility grew across all accounting approaches, with significant regional variations in transfers.

Area of Science:

  • Environmental Science
  • Economics
  • Computer Science

Background:

  • The Information and Communication Technology (ICT) sector's environmental impact is a growing concern.
  • Understanding carbon emission responsibility is crucial for effective climate policy.

Purpose of the Study:

  • To compare ICT carbon emission responsibility using production-based (PBA), consumption-based (CBA), income-based (IBA), and shared-responsibility (SRA) approaches in China.
  • To analyze the spatial and sectoral patterns of carbon emission transfers within China's ICT sector.

Main Methods:

  • Utilized the environmentally extended multiregional input-output (EE-MRIO) model.
  • Employed China's 2012 and 2017 provincial MRIO tables for analysis.

Main Results:

  • Consumption-based accounting assigned the highest emission responsibility to the ICT sector.
  • Regional emissions were concentrated under PBA and IBA, with significant inter-regional heterogeneity in transfers.
  • The ICT sector exhibits dual carbon lock-in effects, with upstream dependencies on energy-intensive sectors and downstream consumption concentrated in specific sectors.

Conclusions:

  • Consumption-based accounting reveals a higher carbon footprint for China's ICT sector.
  • Policy interventions should consider regional disparities and supply chain dependencies for effective emission reduction.
  • Differentiated emission reduction targets are supported by the findings on regional heterogeneity.
