Poland says it will need cash and help in curbing its emissions if it is to sign up for a new decade of EU green energy policy at talks this month, according to a document seen by Reuters.

The document shows the 28 EU member states are broadly ready to agree a new set of 2030 goals to follow on from 2020 energy and environment policy, although Europe's biggest power Germany says it will not agree a deal "at any price".

Poland has always been the most reluctant of EU member states to sign up for ambitious climate policy before the rest of the world.

It argues that EU emissions account for only a small part of the world's pollution, and that Poland needs help in moving away from its heavy dependency on coal, the most carbon-intensive of the fossil fuels.

The briefing document, drawn up by EU officials ahead of a summit of EU leaders on 23-24 October, says Poland is not convinced about the need for a deal now, but "is working in the spirit of not blocking an agreement".

Members of the current European Commission, meant to step down at the end of this month making way for a new set of officials, say the EU must decide now on its negotiating position ahead of U.N. talks on a global pact on tackling climate change to be hosted by Paris next year.

The executive EU Commission outlined in January its vision for 2030 goals, including a 40% cut in carbon emissions compared with 1990 levels, an improvement in energy efficiency to 30% versus business as usual and a target to get 27% of energy used from renewable sources.
