to support
To support a decision, responsibility, or consequence in principle and share the associated burdens or consequences with others.

'Mittragen' is a separable verb. In a main clause, the prefix 'mit' goes at the end. In the infinitive with 'zu', 'zu' is inserted between the parts: 'mitzutragen'.
Er trug den schweren Koffer allein, weil niemand mitgetragen hat.
He carried the heavy suitcase alone because no one helped carry it.
The prefix 'mit-' always means 'together with others' or 'jointly'. The verb 'mittragen' therefore always describes an action that you do not perform alone.
Alle im Team müssen die Entscheidung mittragen.
Everyone on the team has to support the decision.
The context makes the meaning clear: if it is about physical objects (table, suitcase), the literal meaning is intended. If it is about abstract things (decision, responsibility, costs), the figurative meaning is intended.
Könnt ihr das Sofa bitte mittragen?
Could you please help carry the sofa?
In the figurative meaning, 'mittragen' is often combined with abstract nouns such as 'eine Entscheidung' (a decision), 'die Verantwortung' (the responsibility), 'die Konsequenzen' (the consequences), or 'ein Risiko' (a risk).
Nicht alle Mitarbeiter wollten das Risiko mittragen.
Not all employees wanted to share the risk.
to support
Unterstützen can mean approving of a decision and advocating for it. Mittragen goes further: you support the decision while also taking on part of the responsibility for it or its consequences. Unterstützen is appropriate for mere agreement; when responsibility is shared, mittragen is more precise.

Als Vorstandsmitglied trägt Mira die Entscheidung und ihre möglichen Folgen mit.
As a board member, Mira shares responsibility for the decision and its possible consequences.
Mira unterstützt die Entscheidung des Vorstands, ist aber nicht für ihre Folgen verantwortlich.
Mira supports the board's decision but is not responsible for its consequences.
