The number of delegates with links to fossil fuels at the UN climate summit has increased by 25%.
More than 600 people are linked to fossil fuels, according to Global Witness.
The combined delegation from the 10 most climate-impacted countries is less than that.
The summit will take place in the Red Sea resort of Sharm el-Sheikh, with an estimated 35,000 attendees.
The coal, oil and gas industries like to influence the debate at these conferences.
503 delegates were connected to fossil fuels at last year's summit in Glasgow.
The figure has gone up this year
"COP 27 looks like a fossil fuel industry trade show," said Rachel Rose Jackson, from Corporate Accountability.
We're on a carousel of craziness, not climate action. The agenda of the fossil fuel industry is extremely dangerous. They are motivated by profit and greed. They don't care about climate action. They won't and never will.
The researchers counted the number of individuals who were either directly affiliated with fossil fuel companies or attending as members of national delegations that act for the fossil fuel industry.
There are more fossil fuel lobbyists this year than there are delegates from the countries most affected by climate change.

In the past, we have been failed. There is no guarantee that they won't fail us again.
Dr Ibrahim's group and others struggle to make an impact at the highest levels.
They won't allow us to come because they don't want the other voice heard.
The arguments being made in favor of oil and gas are having an effect.
There has been a "dash for gas" recently among some African nations, eager to exploit their resources at a time when demand in Europe and elsewhere is increasing.
One of the African countries that wants to exploit its recent gas discoveries is Senegal.
"How can we use these resources to develop our country and reinforce our economy and to export it to emerging and developed countries is important for us," said Idy Niang, from the Senegalese delegation.
There should be no room at any COP for those who support fossil fuels because of the seriousness of the climate problem.

"If we have the fossil fuel lobby and machinery in full swing, we won't make progress and we won't make progress at all," he said.
