The data shows that Europeans are reluctant to make significant concessions to Russia, while at the same time agreeing that it is time to push for a solution with Ukraine, euronews writes.
As Ukraine is about to enter its fifth year of full-scale occupation, Kiev is in the process of reviewing the latest version of the US-brokered peace plan, which was first presented last November.
Ukraine and the United States have reached a broad agreement on security guarantees, President Volodymyr Zelensky said last week, but reports suggest disagreements continue over territorial concessions to Russia, the plan's most contentious issue.
Although European leaders have been largely absent from the drafting of the document, public opinion across the continent, compiled by YouGov, shows where Europeans stand on the 20-point proposal, as well as on an earlier 28-point draft.
Respondents in the UK, Germany, France, Spain, Italy and Poland agree that the least acceptable term of a potential peace deal would allow Russia to keep all the Ukrainian territories it currently holds - which make up roughly a fifth of Ukraine.
The next red line would be forcing Kiev to limit its army to 600,000 from its current 800,000.
European citizens also strongly opposed the ban on Ukraine from joining the NATO military alliance.
Opposition to all three proposals - territorial loss, reduced military and lack of NATO membership - is strongest in the United Kingdom, with Spain also emerging as staunch opponents.
At the same time, Italy stands out as the most open to Ukraine making territorial concessions.
While Italians are only slightly opposed to keeping all the territory occupied by Russia, they are the only respondents in Europe who think it would be acceptable to propose that Ukraine hand over the Donbas region to Russia in order to end the war.
Supporting Ukraine until final victory or pushing for a deal?
However, respondents remain divided on the central question of supporting Ukraine until victory or pushing for a peace plan.
British and Polish respondents think Europe should support Ukraine until Russia withdraws, but a majority of those interviewed in Germany, France, Italy and Spain say they would support a peace deal - even if it involves Russia holding onto parts of Ukrainian territory.
What has Europe proposed and what comes next?
Earlier in December, leaders from Germany, Denmark, Finland, France, Italy, Lithuania, the Netherlands, Norway, Poland, Sweden, the United Kingdom and the EU agreed on a six-point European plan.
Rather than proposing a rival to the US proposal, the leaders presented their ideas as building on what was already on the table - showing what they call "strong convergence between the US, Ukraine and Europe".
The plan also proposes a more practical European role in Ukraine's post-war future, pledging to help regenerate Ukraine's forces, secure its skies and support safer seas, "including through operations inside Ukraine."
However, it does not go into detail on the issue of territory, stating only that such decisions "are for the people of Ukraine, once strong security guarantees are effectively established."
On Tuesday, over 20 countries from the Coalition of the Willing met in Paris to clarify more about their security commitments to Ukraine.
A joint statement said they agreed to continue long-term military assistance and armaments to Ukraine's armed forces, which "will remain the first line of defense and deterrence" after the signing of any peace agreement.
They also pledged to provide preventive measures on land, sea and air once "a credible cessation of hostilities has occurred."
