Leaders from all over the world are currently gathering at the Conference of the Parties of the UNFCCC (COP 27) in Egypt to discuss climate action, and to negotiate the commitments being made by countries to the global climate agenda.

This visualization based on data from the Global Carbon Project shows the changes in global fossil fuel carbon dioxide (CO₂) emissions from 1900 to 2020, putting the challenge of fighting climate change into perspective.

Cumulative CO₂ Emissions vs. Rate of Change

Global climate change is primarily caused by carbon dioxide emissions. Fossil fuels like coal, oil, and gas release large amounts of CO₂ when burned or used in industrial processes.

Before the Industrial Revolution (1760-1840), emissions were very low. However, with the increased use of fossil fuels to power machines, emissions rose to 6 billion tonnes of CO₂ per year globally by 1950. The amount had almost quadrupled by 1990, reaching a rate of over 22 billion tonnes per year.

Currently, the world emits over 34 billion tonnes of CO₂ each year. Since 1751, the world has emitted over 1.5 trillion tonnes of CO₂ cumulatively.

Cumulative CO2 Emissions

Prior to the COVID-19 pandemic, average global growth in fossil CO₂ emissions had slowed to 0.9% annually during the 2010s, reaching 36.7 gigatons of CO₂ (Read more...)
