The party blames net zero policies for higher energy bills and deindustrialisation in the UK and believe green initiatives will make "zero difference to climate change".
The study - commissioned by thinktank the Energy and Climate Intelligence Unit (ECIU) - found for every £1 of value generated by the net zero economy, an additional £1.89 was created in the wider economy.
Some Conservative and Reform MPs have criticised net zero, electric cars and renewables, suggesting efforts to curb climate change are to blame for higher energy bills and the deindustrialisation of Britain.
Energy Secretary Ed Miliband said the findings showed "net zero is essential to growth, a strong economy, and money in working people's pockets".
It comes as the government increases efforts to meet a legally binding goal to cut greenhouse gas emissions to zero overall (that's net zero) by 2050.
