It describes socialism as "an answer to the problems caused by capitalism such as non-sufficient democracy, crises, destruction of nature, inequality, racism and war".

[24]The Red–Green Alliance recognizes that methods achieving this may differ depending on the course of class struggle, but will eventually require a revolution—one that must be supported by a majority of the population manifested through democratic and free elections.

The party places great emphasis on the fight against social inequality and poverty, and is in favour of strengthening and expanding the welfare state.

The party believes there is a place in society for all forms of diversity, including gender, sexuality, disability and ethnic background.

In response to the Great Recession of 2007–2009, the Red–Green Alliance urged stricter control of loans, the introduction of a Tobin tax, and the nationalisation of banks and mortgage companies.

It also believes that the public sector must be expanded, the wages of the lowest-paid workers raised, and that the insurance-based unemployment benefit period should be extended to a minimum of four years.

[32] The party advocates for foreign policy based on the respect for human rights, which it believes has never been appropriately prioritised in the past.

It also proposes greater support for developing countries through a doubling of foreign aid,[34] and campaigns for Denmark's withdrawal from NATO.

In March 2019, the party announced it would no longer campaign for a referendum to leave the EU, pointing to Brexit illustrating the need for clarity before withdrawal can be considered.

Originally the plan was to unite these parties alongside The Greens (De Grønne), Common Course, and Humanist to form a broad-based progressive movement, but this did not materialize.

[45] As part of the left-leaning "Red bloc" coalition with the Social Democrats, the Red–Green Alliance accepted the government budget twice and was in opposition twice in the period from 2011 to 2015.

In the 2022 Danish general election, it became the largest party in 4 nomination districts of the municipality, namely Inner City, Nørrebro, Bispebjerg and Vesterbro.
