A total of 1,150 groups lobbied Congress on climate change during the second quarter of 2009, according to an analysis by the Center for Public Integrity (CPI).
Manufacturers lead the push to influence future legislation with more than 200 companies and advocacy groups working the halls of Congress.
Additionally, some 130 power and utility companies and advocacy groups joined the mix, as well as 80 agriculture interests and 20 for biofuel.
The total number of lobbying groups grew 30% from the first quarter and included natural gas, smart grid, higher education and religious interests.
"It is clear that the Senate faces formidable challenges as this lobbying force of more than 1,100 seeks to sway the debate," CPI said.
