The Scope 4 Emission: Neutralized Carbon Emissions
Zhu Liu, Guangqian Wang

TL;DR
This paper introduces a new framework for quantifying carbon-negative and neutral actions, calculates global Scope 4 emissions from renewable energy, and highlights China's significant contribution to global climate mitigation.
Contribution
It presents the first calculation of global Scope 4 emissions from renewable energy and emphasizes China's leading role in carbon neutrality efforts.
Findings
China's Scope 4 emissions are 2.15 Mt C/day, surpassing US and EU27 & UK combined.
China accounts for over 36% of global neutralized CO2 emissions.
Scope 4 emissions are increasing globally, reflecting progress in renewable energy adoption.
Abstract
Assessing carbon negative and carbon neutrality is critical for mitigating and adapting global climate change. Here we proposed a new framework to account for carbon-negative and carbon-neutral actions by introducing the definition of Carbon Negative (C0),Carbon Neutrality Stock (C1), Carbon Supply (C2) and carbon-neutral emissions or Scope 4 emissions, which refers to the avoided emission due to use of non-fossil energy or C1 products. For the first time, we calculated the global neutralized carbon emissions or Scope 4 emission by renewable electricity generation, and the results indicating the significant contributions by China, with total neutralized carbon emissions (2.15 Mt C/day ) much higher than the U.S. (0.85 Mt C/day)and EU27 & UK (1.25 Mt C/day) together. We show that China contributed to more than 36% of global neutralized CO2 emissions, and such contributions are still…
