BRUSSELS — The European Commission is expected to introduce a plan to reduce greenhouse gas emissions that directs the largest slices of €50 billion available for research and development to solar power and capturing and burying emissions from coal plants.

The plan, to be released on Wednesday, is partly intended to show that the European Union is taking the additional steps needed to meet ambitious goals to cut greenhouse gases before a summit meeting in Copenhagen in December on reaching a new global agreement to curb climate change.

But the plan also signals the need for a reordering of the bloc’s industrial priorities by requiring governments to spend significantly greater sums of money on clean energy even as the world emerges from a deep financial crisis.

“Markets and energy companies acting on their own are unlikely to be able to deliver the needed technological breakthroughs within a sufficiently short time span to meet the E.U.’s energy and climate policy goals,” the commission said in a draft of the plan obtained by the International Herald Tribune.
