Global fossil co₂ emissions set to unexpectedly decrease in 2026

Published 10.11.2026

Global fossil co₂ emissions are set to decrease 0.4% in 2026 as the energy shock driven by the closure of the Strait of Hormuz reduces oil and gas use. Clean energy growth continues but remains insufficient for a structural peak and decline in emissions.

New figures confirm: Global fossil co₂ emissions continue a persistent rise

Published 13.11.2025

Global fossil co₂ emissions are projected to rise 1.1% in 2025, and are now 10% higher than in 2015, ten years since the Paris Agreement was adopted.

Climate effect of nitrogen emissions is uncertain

Published 22.10.2025

The climate effect of nitrogen emissions is uncertain, according to a new study led by CICERO and published in Nature. Increased knowledge is crucial before introducing new zero carbon-fuel technologies on a large scale.

The Winding Road to 1.5 Degrees

Published 3.10.2025

To limit global warming to around 1.5 degrees, we must remove CO₂ from the atmosphere. Exactly how much can be removed is uncertain. The only thing that seems sure is that it will be a massive cleanup job. Nevertheless, many countries have this as a strategy to reach their climate goals.

Separating land carbon uptake from net-zero emissions

Published 19.11.2024

How are net zero emissions defined? It matters. It is the difference between either halting or continuing global warming, writes senior researcher Glen Peters in this blog about a new study published in Nature.

Still no peak in global fossil co₂ emissions

Published 13.11.2024

Global fossil co₂ emissions are expected to grow 0.8% in 2024, despite predictions of peak emissions. The positive progress in many countries and clean technologies is offset by persistent fossil fuel use.

Alternative aviation fuels offer limited mitigation potential

Published 24.6.2024

The use of alternative fuels could be one way for the aviation sector to reduce its emissions. A new study of fuel use in domestic flights in Norway shows some mitigation potential for alternative fuels, but warns that these alternatives are neither emission-free nor climate-neutral.

Global fossil CO₂ emissions are projected to rise in 2023

Published 19.10.2023

How are global emissions projected to develop in the years to come? To reach pathways consistent with the goals in the Paris Agreement, global CO₂ emissions should be falling by around five percent this year.

Greenhouse gas emissions at ‘an all-time high’ - and it is causing an unprecedented rate of global warming, say scientists

Published 8.6.2023

Human-caused global warming has continued to increase at an “unprecedented rate” since the last major assessment of the climate system published two years ago, say 50 leading scientists in a new paper in the journal Earth System Science Data.

Global fossil co₂ emissions increase amidst turmoil in energy markets

Published 11.11.2022

Global fossil co₂ emissions are expected to grow 1.0% in 2022 as the COVID recovery continues amidst turmoil in energy markets. Growth in oil use, particularly aviation, and coal use are behind most of the increase in 2022.

Projects

EYE-CLIMA - Verifying emissions of climate forcers

The EU funded project EYE-CLIMA aims to improve estimates of emissions and removals of the most important greenhouse gases, namely, co₂, methane, N2O and six F-gases, as well as the aerosol black carbon.

4C – Climate-Carbon Interactions in the Current Century

The EU-funded project 4C (Climate-Carbon Interactions in the Current Century) aims to fill the knowledge gap surrounding climate sensitivity to carbon dioxide emissions by reducing the uncertainty in our quantitative understanding of carbon-climate interactions and feedbacks.

VERIFY: Observation-based system for monitoring and verification of greenhouse gases

The EU-funded project VERIFY developed a system to estimate greenhouse gas emissions to support EU countries' emission reporting to the UN Framework Climate Change Convention Secretariaton Climate Change (UNFCCC). The emissions were estimated based on land, ocean and atmospheric observations. The project focused on the three major greenhouse gases responsible for global warming: carbon dioxide (co₂), methane (CH4) and nitrous oxide (N2O).

COP30: Climate Effect of Black Carbon and Methane in the Arctic. Scientific Revisions, Policy Decisions

Black carbon (BC) and other short-lived climate forcers emitted within the Arctic and at lower latitudes are making a significant contribution to warming and have been a subject of study in recent years by Arctic Monitoring and Assessment Programme (AMAP). How the contribution of BC to Arctic climate change is likely to evolve in future is unclear, both due to uncertainties in future emission scenarios and given the complexity of the climate system and of the effects of different atmospheric pollutants, many of which are co-emitted.

Where are global CO₂ emissions heading?

Despite growth in renewable energy production around the world, fossil fuel use looks set to rise again in 2024. How much must countries cut emissions to stay on track to reach the goals in the Paris Agreement?

Where are global CO₂ emissions heading?

In this webinar, CICERO researchers involved in the Global Carbon Project explain why global fossil CO₂ emissions are projected to decline in 2026, whether this marks the beginning of a sustained decline, and what role the conflicts in Iran and Ukraine, clean energy growth, and El Niño are playing in shaping the global carbon budget. We also take a deep dive into what is happening in key countries.

Research groups

Atmospheric Sciences

The research group covers a broad range of topics within the atmospheric sciences. We are primarily a modelling group, studying radiative forcing of the climate system, and the role of gases, aerosols and clouds.

Climate Mitigation

The research group works to understand the trends and drivers of historical and future emissions of greenhouse gases and short-lived climate forcers, and their effect on the climate.
