Fossil CO2 emissions at record high in 2023

Key messages The annual Global Carbon Budget projects fossil carbon dioxide (CO2) emissions of 36.8 billion tonnes in 2023, up 1.1% from 2022. Fossil CO2 emissions are falling in some regions, including Europe and the USA, but rising overall – and the scientists say global action to cut fossil fuels is not happening fast enough […]

CALIPSO Press Release

The fate of carbon emissions from fossil fuel burning and deforestation determines the rate of increase of atmospheric CO2 increase, and in turn, climate change. The physics-based models used for future climate projections predict a weakening of both land and ocean sinks (e.g. absorption)  in response to a warming climate, resulting in a steeper rise […]

Exeter researchers comment on IPCC report

The Synthesis Report is a summary of the latest (sixth) round of IPCC assessments of climate change, its impacts and the solutions available. The IPCC says global warming has created “increasingly dangerous impacts on nature and people in every region of the world” – but “urgent climate action can secure a liveable future for all”. […]

Exeter expert comments on CO2 removal report

Massive deployment of CDR is critical to reach net zero emissions and stabilise the climate as quickly as possible. The report highlights that current CDRs which takes up two billion tonnes of CO2 (GtCO2) per year, are primarily due to conventional land management such as reforestation. Novel technologies, such as direct air capture, are still negligible, […]

No sign of decrease in global CO2 emissions

If current emissions levels persist, there is now a 50% chance that global warming of 1.5°C will be exceeded in nine years. The new report projects total global CO2 emissions of 40.6 billion tonnes (GtCO2) in 2022. This is fuelled by fossil CO2 emissions which are projected to rise 1.0% compared to 2021, reaching 36.6 […]

Cut emissions ‘starting now’ – Global Carbon Project experts

In the following article, Professor Pierre Friedlingstein, of Exeter’s Mathematics department and Global Systems Institute (GSI), and Alissa Haward, GSI Project Manager, discuss the findings and their relevance to the climate crisis. Our analysis from the Global Carbon Budget, published this week concludes that if we want to reach net zero CO2 emissions by 2050 we must cut global CO2 emissions by about […]

Global carbon emissions rebound close to pre-Covid levels

Fossil carbon emissions dropped by 5.4% in 2020 amid Covid lockdowns, but the new report projects an increase of 4.9% this year (4.1% to 5.7%) to 36.4 billion tonnes. Emissions from coal and gas use are set to grow more in 2021 than they fell in 2020, but emissions from oil use remain below 2019 […]

Exeter researcher elected Fellow of Royal Society

Professor Pierre Friedlingstein leads the Global Carbon Budget and has contributed to Intergovernmental Panel on Climate Change (IPCC) reports. He studies the terrestrial biosphere’s response to climate change, and had made multiple key contributions to our understanding in this vital field. The Royal Society is a Fellowship of many of leading scientists, and is the oldest scientific academy […]
