This page is just one in our collection of work on CO2 and Greenhouse Gas Emissions where you can explore emissions of other greenhouse gases; where our emissions come from; what trajectories of future emissions look like; and what is driving emissions across the world.
Global growth in energy-related CO2 emissions slowed in 2025, rising by around 0.4%, the slowest rate since 2021. Despite this slowdown, total energy-related CO2 emissions increased by around 145 million tonnes (Mt) in 2025, reaching a new high of nearly 38.4 billion tonnes (Gt) 1, and 5% above 2019 levels. The increase coincided with record atmospheric CO2 concentrations of about 427 parts ...
Emissions refer to the release of gases, including carbon dioxide (CO2), methane, nitrous oxide, and others, into the atmosphere. These gases profoundly affect the Earth’s climate, contributing to the greenhouse effect, which leads to rising global temperatures and extreme weather.
Data and information on CO2 emissions by country, including the countries with the highest CO2 emissions in the world and countries with the highest CO2 emissions per capita in the world.
The projected rise in CO2 emissions in 2025 is driven by growth in coal, like the coal-fired plant pictured, as well as oil and gas, according to the 2025 Global Carbon Budget Report. Global carbon ...

Emissions of carbon dioxide – the gas most responsible for global warming – continued to rise in Earth's atmosphere in 2022, federal scientists announced recently. Carbon dioxide (CO2) in the ...
