Ahead of Donald Trump's meeting with Sir Keir Starmer in Aberdeen, AGCC has called on the US president to persuade Starmer to ditch the disastrous Energy Profits Levy.
The so called windfall tax is the single biggest barrier to North Sea investment, resulting in a 78% headline tax rate on profits.
Trump is set to meet with Starmer and John Swinney during a trip to Aberdeen, and is expected to make the case for ramping up domestic oil production.
Ahead of the meeting, a spokesperson for AGCC said: “We are extremely proud that Aberdeen is Europe’s energy capital - a reputation built on global expertise in oil and gas, with skilled people and great businesses primed to realise huge opportunities ahead in renewables and new technology.
“For as long as we require oil and gas as part of our energy mix over the decades to come, we should produce as much of that as possible from the North Sea - sustaining jobs and growing our economy.
"The biggest barrier to investment in the North Sea is a 78% tax rate on profits and perhaps the US President can persuade the Prime Minister to lift that punitive tax when they meet in Aberdeen."
Trump revealed to the BBC that the meeting would take place in Aberdeen, describing it as "the oil capital of Europe".
The private visit comes ahead of the president's full state visit later this year.
Trump told the BBC: "We're going to have a meeting with... a state meeting with the prime minister, and that's going to be up in Aberdeen, which is the oil capital of Europe, they should bring it back too."
