Have global carbon dioxide (CO2) emissions gone up or down this year?
The latest projections from the Global Carbon Project give us some insight. Their researchers and analysts do invaluable work in estimating greenhouse gas emissions worldwide, helping us understand how the situation is evolving.
Today, they published their latest “carbon budget”. The chart shows their historical estimates, as well as their projections for 2025.
They project that this year, emissions from fossil sources — that is, from fossil fuels and industrial processes — will increase by around 1%. Emissions from all three fuels — coal, oil, and gas — are expected to increase. Meanwhile, emissions from land-use change have decreased due to fewer extreme wildfires and reduced deforestation in South America.
This reduction in land use may offset the increase from fossil fuels, resulting in a global total similar to last year. Note that estimates for land-use emissions are much less certain than for fossil fuels.
While many countries have made progress in reducing emissions, global fossil emissions continue to rise. To tackle climate change, they need to peak and rapidly decrease in the coming years and decades.
