The Jersey Greenhouse Gas Statistics show more than 20,000 tonnes extra was produced in 2021, compared to the year before.
This takes the total emissions that year up to 358,435 tonnes, around 3.5 tonnes per islander, and in 2020 carbon generations sat at 335,880 tonnes.
Despite an increase in figures, Jersey has seen an overall decrease of 46% in greenhouse gas emissions since 1990 when records began.
Climate Change Minister, Deputy Hilary Jeune, says the 2022 report will show a true picture of where we are post-Covid.
"What’s particularly pleasing is that despite the increase in home working, residential emissions continued to fall."
Transport was the most prominent contributor at 41%, but the government has since taken steps to encourage islanders to help by making small changes.
Deputy Hilary Jeune says as part of the 2050 Carbon-Neutral Roadmap, the government want to see islanders switching away from fossil-fuel vehicles.
"Our real focus on encouraging active travel, through schemes such as the e-bikes incentives, will help ensure our road transport emissions move in the right direction."
