The Partnership for Action on Green Economy (PAGE), a UN mechanism to assist countries transition towards greener and more inclusive economies, emerged at

Explicitly links Rio+20 (2012) with a focus on the 'Green economy' and institutional framework for sustainable development.

A student could infer that initiatives explicitly about a 'green economy' are more likely to have been launched or emphasised at Rio+20 (2012) than at Johannesburg 2002, and check PAGE's founding date against 2012.

Describes the Johannesburg 2002 outcomes (the Johannesburg Plan of Implementation) and their emphases (Agenda 21, MDGs), showing the summit's documented priorities.

Use this pattern to judge whether a programme about the 'green economy' fits Johannesburg 2002's documented priorities or seems more aligned with later Rio+20 themes.

Lists milestones including Rio+20 and Sustainable Development initiatives (SDSN, SDGs), indicating an ongoing evolution of sustainability agendas after 1992 and 2002.

A student could use this timeline pattern to place the likely origin of a green-economy partnership within the sequence (e.g., closer to Rio+20) and then verify PAGE's founding year.

Notes that the 2012 UN Conference (Rio+20) was a UN conference on sustainable development, reinforcing that major new themes (like green economy) were advanced at Rio+20 rather than earlier summits.

Combine this with the explicit green-economy link at Rio+20 (snippet 10) to suspect PAGE more plausibly emerged around 2012 than at Johannesburg 2002.

Summarises the original Earth Summit (1992) outputs (Agenda 21, conventions), showing earlier summits set different agendas and naming conventions for initiatives.

A student could contrast the 1992/2002 summit outputs with the later green-economy emphasis to assess whether PAGE fits the 2002 summit's typical outputs or a later shift.
