Towards real-time verification of CO2 emissions


Emissions of CO2 from fossil fuels and industry did not change from 2014 to 2016, yet there was a record increase in CO2 concentration in the atmosphere. This apparent inconsistency is explained by the response of the natural carbon cycle to the 2015-2016 El Niño event circulation, but it raises important questions about our ability to detect a sustained change in emissions from the atmospheric record. High-accuracy calibrated atmospheric measurements, diverse satellite data, and integrative modelling approaches could, and ultimately must, provide independent evidence of the effectiveness of collective action to address climate change. This verification will only be possible if we can fully filter out the background variability in atmospheric CO concentrations driven by natural processes, a challenge that still escapes us.

Global Carbon Budget 2017

The Global Carbon Project has released its 2017 edition of the world’s carbon budget, including historical emissions by country back to 1751. This multidisciplinary and international effort provides a set of consistent supporting data for further analysis.Learn more »

Global Carbon Budget Figures

Every year the Global Carbon Project publishes a number of figures demonstrating the latest global carbon budget, and these are freely available for use in a number of formats.Learn more »

Warning signs

For the last three years, emissions were stable, despite continuing growth in the global economy. However, the temporary hiatus appears to have ended in 2017. Learn more »
