TL;DR
The world still runs on fossil fuels, and whether emissions fall depends on Asia-Pacific and low-income countries, not on how much Europe and America cut at home.
The Statistical Review of World Energy comes out every year and it is mostly numbers. The author's takeaway: add up global energy supply and you get roughly 600 exajoules, and the grey slices of that chart are all coal, oil and gas.
Who emits, and who is still climbing
On 2025 figures, the US accounts for 13.3% of the world's energy-related carbon emissions and Europe 9.9%, both falling slowly over the past decade. The real weight sits in Asia-Pacific: 53.4%, and still growing about 2% a year.
China alone is 31.3% and India 8.3%, both rising.
Per head, the problem gets sharper
Africa averages 14 gigajoules of energy supply per person, India 26, Europe 106, the US 270. If low-income countries are going to develop, their energy use has to multiply — there is no pretending otherwise.
So a few less car trips in Ohio or Bavaria barely moves the global total. What rich countries can actually do is supply the technology and the capital that lets Asia-Pacific and low-income nations build out low-carbon energy instead.
Why it matters
The most common mistake in climate debate is treating the West's emissions curve as the world's. This data says where the money and technology should go: not into shaving more off at home, but into giving the half of the world still climbing a different ramp to climb.
