Carbon Emissions and Its Scopes

Carbon emissions

Carbon emissions refer to the release of carbon compounds, particularly carbon dioxide, into the atmosphere, primarily from human activities such as burning fossil fuels and deforestation, contributing to climate change.

Where Carbon emission is standing?

Carbon emissions show a persistent yearly increase, exacerbating environmental concerns and contributing to climate change. In year 2021, global CO2 emissions hit a record 36.3 gig tonnes, a 6% increase from 2020. The COVID-19-induced 5.2% drop in emissions in 2020 was reversed by a rapid economic recovery fuelled by fiscal measures and vaccinations. Despite renewable energy growth, adverse conditions led to higher coal use. The 6% emission increase aligned with a 5.9% global economic output growth, marking the strongest link between CO2 and GDP since 2010. This surge surpassed the 2020 decline, placing 2021 emissions 180 mega tonnes above pre-pandemic 2019 levels. 

In 2022, global energy-related CO2 emissions rose by 0.9%, reaching a record 36.8 Gt. This increase, slower than 2021’s rebound, resulted from a 321 Mt rise in energy combustion emissions, while industrial process emissions decreased by 102 Mt. The trends reflect post-pandemic fluctuations. 

Some scopes of carbon emission

Scope 1 – emissions refer to direct greenhouse gas emissions that originate from sources that are owned or directly controlled by a specific organization or reporting entity. These emissions are a result of activities within the organization’s operational boundaries.

Scope 2- emissions are indirect greenhouse gas emissions associated with the consumption of purchased energy. These emissions occur as a result of the generation of electricity, steam, heating, or cooling that an organization buys from an external source. The reporting entity doesn’t directly control the production of this energy but is responsible for the emissions associated with its consumption.

Scope 3- emissions encompass all indirect greenhouse gas emissions associated with a company’s value chain that are beyond its direct ownership or control. These emissions occur as a result of the company’s activities but are generated by sources external to the organization itself.


In 2021, global carbon emissions soared to a record 36.3 gig tonnes, witnessing a 6% spike from the previous year due to a swift economic rebound following the COVID-19 pandemic. Despite growth in renewable energy, the surge was fuelled by increased coal usage and a robust correlation between CO2 emissions and GDP expansion. In 2022, emissions edged up by 0.9% to reach 36.8 Gt, reflecting post-pandemic fluctuations. The persistent annual rise in carbon emissions continues to heighten concerns about climate change. The three categories of carbon emissions are Scope 1 (direct emissions), Scope 2 (indirect emissions from purchased energy consumption), and Scope 3 (indirect emissions in a company’s value chain).
