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.

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.

Global fossil co₂ emissions continue to increase despite clean energy progress

Published 5.12.2023

Global fossil co₂ emissions are expected to grow 1.1% in 2023 despite record progress in clean energy. A renewed focus on limiting the use of coal, oil, and gas is needed.

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.

Global co₂ emissions return to near pre-COVID pandemic levels

Published 4.11.2021

Global fossil co₂ emissions are expected to grow 4.9% in 2021, nearly offsetting the 5.4% decline in 2020 due the COVID restrictions. Coal and gas use rebounded strongly to exceed 2019 levels, while oil use remains suppressed, suggesting strong policy action is needed to avoid continued emissions growth in 2022.

Natural gas and oil use push up global co₂­ emissions in 2019, according to latest data

Published 4.12.2019

Global co₂ emissions are projected to rise a low 0.6% in 2019 due to robust growth in natural gas and oil use, and despite a decline in coal consumption. Natural gas has been the dominant driver of global emissions since 2012.

Global co₂ emissions rise again in 2018

Published 5.12.2018

Global co₂ emissions are on track to rise more than 2% in 2018 on the back of renewed growth in coal use, and continued growth in oil and gas use, according to data released on 5 December.

Projects

DIAMOND - Delivering the next generation of open Integrated Assessment MOdels for Net-zero, sustainable Development

The DIAMOND project contributes to the development of the next generation of integrated assessment models (IAMs), which will be fully open and sufficiently equipped to scientifically underpin and support an accelerated transition towards circular, resilient, desirable, and sustainable climate neutrality.

CICERO is helping to develop a new global emissions monitoring service (Coco₂)

Together with 24 partners in 14 countries, CICERO is working to develop a European operational service for monitoring global greenhouse gas emissions, as part of the EU-funded project Prototype system for a Copernicus co₂ service, the Coco₂ project.

ICOS (Integrated Carbon Observation System) is a programme within the European Strategy Forum on Research Infrastructures (ESFRI) list of European infrastructures.

Climate Models

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).

Global carbon budget

The Global Carbon Project aims to develop a complete picture of the global carbon cycle, including both its biophysical and human dimensions together with the interactions and feedbacks between them. CICERO plays a key role in this work.

Research groups

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.

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.
