The development of a highly accessible bus network in the city of Curitiban Brazil. The network is designed to reduce pollution and congestion while being accessible to all neighbourhoods regardless of economic status.

• A. The Environmental Pillar
• B. E.G
• C. The Social Pillar
• D. Economic Pillar

Answer: (B)

The scenario tests how a project can address multiple sustainability dimensions at once. A highly accessible bus network lowers pollution and reduces congestion, which clearly fulfills environmental goals. At the same time, making the network accessible to all neighborhoods regardless of economic status targets social equity by ensuring transportation is not limited by income. In many ESG-style frameworks, this combination of environmental benefits with governance/social considerations is captured by the E.G labeling used in the key. So, the best fit here is the option that represents this environmental plus governance/social emphasis. The economic angle isn’t the primary focus of the description, which is why the environmental/social blend is the strongest match.
