Option Analysis

• The Brundtland Report The Brundtland Report: Correct. The report 'Our Common Future' is commonly known as the Brundtland Report, named after the commission's chairperson, Gro Harlem Brundtland (former Prime Minister of Norway). It provided the classic definition of sustainable development: "Development that meets the needs of the present without compromising the ability of future generations to meet their own needs." This report laid the foundational framework for the Rio Earth Summit (1992).
• The Stern Review The Stern Review: Incorrect. The Stern Review on the Economics of Climate Change was released in 2006 by economist Nicholas Stern for the UK government. It focuses on the economic costs of climate change and the benefits of early action.
• The Meadows Report The Meadows Report: Incorrect. This refers to 'The Limits to Growth' (1972), a study commissioned by the Club of Rome and led by Donella and Dennis Meadows. It modeled the consequences of exponential growth in population and industrialization against finite resources.
• The Bali Roadmap The Bali Roadmap: Incorrect. This was adopted at the UNFCCC COP 13 in Bali, Indonesia, in 2007. It set a two-year process to finalize a binding agreement on climate change (which was intended for Copenhagen 2009).

Key Takeaway: The Brundtland Report (1987), officially titled 'Our Common Future', is the seminal document that defined Sustainable Development and catalyzed the global environmental agenda leading to the 1992 Rio Earth Summit.
