Global carbon dioxide emissions from fossil fuels and industry have renewed their climb after a three-year pause, driven higher by quickening economic growth and the failure to find alternatives particularly to oil, international researchers say.

Carbon emissions will rise 2 per cent in 2017 to almost 37 billion tonnes as the world economy heads for 3.6 per cent annual growth. Total emissions, including from land clearing, push that tally to 41 billion tonnes.

A slightly faster pace of GDP expansion in 2018 will also send emissions from industry and fossil fuel combustion higher for at least another year, according to the 2017 Global Carbon Budget.

"This year's carbon budget news is a step back for humankind," said Amy Luers, executive director of Future Earth, a sponsor of the report.
