The Clean Energy Regulator issued 17.2 million Australian Carbon Credit Units (ACCUs) in 2023, and expects this figure to rise to a record 20 mln in 2024, it said in its latest quarterly report, published Wednesday.

Rate of decline in 2023 thought to be linked to climate breakdown as UK-wide survey shows mixed picture across 58 species

The small tortoiseshell butterfly has suffered its worst year on record in England, and has declined by 82% across the UK since 1976, according to the annual scientific count of butterfly populations.

The sharp decline in numbers of the once-common garden butterfly has puzzled scientists, but it is thought to be linked to climate breakdown. It had its worst year on record in England, its second worst in Wales and its joint-fifth worst in Scotland in 2023 but did well in Northern Ireland, logging its second-best year.
