Commitment: 253.1 Mt by 2030, which is 68% below 1990. Starting from 407.5 Mt in 2020, when the target was set, the straight path needed 330.3 Mt by now.

What it means: this is the UK's international climate pledge for 2030, on the way to net zero by 2050. A falling line is good. Most of the cut since 1990 has come from cleaner electricity; transport emissions have barely moved.
