His was influenced by the former chairman of the Social Democratic Party and former environment minister Svend Auken, whom he met during his time in Frit Forum.

Dan Jørgensen is an external lecturer and has taught courses on environmental and climate policy at Seattle University and Sciences Po in Paris.

In February 2014, as Minister for Food, Agriculture and Fisheries, Jørgensen signed a regulation which banned ritual slaughter of animals without prior stunning.

Jørgensen and his government have made international news with the agreement to reduce Denmark's territorial emissions by 70% in 2030 compared to 1990,[11] the decision to stop oil and gas exploration after 2050,[12][13] and the energy islands in the North Sea.

[14] Also in 2020, Denmark agreed with Germany on closer cooperation in their offshore wind power development via clusters in the North and Baltic Seas to spur renewable energy and hydrogen production.

Subsequently, Dan Jørgensen said that with the agreement on green tax reform, Denmark has reached more than two-thirds of the way to the goal of a 70 percent reduction in emissions in 2030.

Similarly, Jørgensen has been criticised[19] for allowing companies to continue the build-out of fossil fuel infrastructure like a natural gas pipeline of 115 km, with an associated cost of $113 million for Denmark.

[20] In a formal answer to the Parliament, Dan Jørgensen confirmed that the gas pipeline would not reduce the carbon emissions in the short term nor add any jobs in Denmark.

[21] Dan Jørgensen received a "nose" in June 2020, a formal criticism by a majority in the Parliament for delaying negotiations with other political parties on biofuels.

Some examples include a podcast in English called Planet A[27] and a campaign with videos on Facebook advising Danes to put more vegetables in their meatballs.

[30] With the formation of a new coalition government after the November 2022 general election, Jørgensen was appointed Minister for Development Cooperation and Global Climate Policy.

[39] Dan Jørgensen has written a number of books about European affairs, climate and environmental policy and Social Democratic history and ideology.
