Carbon budget

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 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.

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 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. 

COMMENTARY: A new paper suggests a rather significant upward revision of the carbon budget for 1.5°C. This is a potential game changer, but it is too early to reformulate mitigation plans.

COMMENTARY: Carbon dioxide emissions from fossil fuels and industry flattened in the last few years, and many argue we are now decoupling emissions from economic growth. Is this a success story or an unfortunate use of the concept?

Keeping global warming below 2°C is hard, but 2.5°C is a walk in the park!

No, Carbon Capture and Storage and Carbon Dioxide Removal allow the continued use of fossil fuels. But for how long? And what are the risks?

COMMENTARY: Despite the complexity of the climate system, there is a rather simple relationship between the long-term temperature increase and the total amount of carbon dioxide emitted. Why, then, is there no clear answer to how much we can emit?
