Fossil CO2 emissions decrease by 0.4% in 2026

Global fossil CO2 emissions fall for the first time, but partly thanks to the Iran conflict

The 2026 Global Carbon Budget projects fossil CO2 emissions will drop 0.4% to 38.2 billion tonnes, driven by solar and wind expansion and a 1.9% fall in oil emissions after the Iran conflict's energy shock. Total CO2 including land-use change still rises to 43.3 billion tonnes. Researchers warn a decline built partly on geopolitical shocks isn't sustainable, and the remaining 1.5°C carbon budget is down to 150 billion tonnes — under four years of current emissions.

A decline in fossil CO2 emissions is encouraging, but a reduction driven partly by geopolitical shocks is not a sustainable climate solution.

    Emissions budgets are calculated using accounting best practice, which are not designed for full transparency (ref: the creative accounting used to obscure every financial scandal and economic bubble). THIS is the curve that matters:

    The Iran blip is clearly seen, but it's just that - a blip. Levels continue to steadily rise.

    The headline buries the lede.

    "With emissions from land-use change (such as deforestation) projected to increase slightly this year, total CO2 emissions are projected to be 43.3 billion tonnes in 2026 – up from 42.8 billion tonnes last year."

    Total annual CO2 emissions are projected to increase by ~half a billion tonnes as a result of land use changes.

    This is good, but also total emissions still expected to increase? Yeesh

    One of the things that COVID make crystal clear to me is that radical changes for the better are much more straightforward than people think, and the only reason they don't happen is the people in charge couldn't be bothered.

    There is no excuse for every government in the world to not be covering every bit of rooftop or scrap land with solar. China is losing money on panels at the moment they have such production capacity. Its free money for anyone country who wants to do it.

    Say what you like but this is great news. Let’s keep going.

    Let's hope it's not just a temporary dip, I'm not holding my breath but we could really do with some longer term good news at the moment.

    Now: Let's skip the AI build out and keep things in the right direction.

    0.4% sounds like one solid volcano eruption and all that effort is gone.
