The somewhat static interpretation of CBDR-RC prior to the Paris Conference of the Parties was overcome through the introduction of a qualification to the CBDR-RC principle: the phrase 'in the light of different national circumstances'. Without changing the original principle, the qualifier adds a dynamic element . Common but differentiated responsibilities and respective capabilities of parties are therefore recognised not to be 'tied to the annexes', but instead evolve alongside national circumstances . The Paris Agreement also recognises context, considering differentiation in relation to each of the Durban pillars: mitigation, adaptation, finance, technology, capacity building and transparency .
