Achieving a zero-carbon world requires a multifaceted approach, and architecture plays a critical role. Strategies include designing buildings that are highly energy-efficient, with excellent insulation, natural lighting, and passive heating and cooling. 

Renewable energy sources like solar panels and wind turbines are integrated to meet power needs without fossil fuels. Sustainable materials are used to reduce the carbon footprint of construction. Water conservation is also a focus, with systems for collecting and recycling rainwater. Beyond individual buildings, urban planning aims to create compact, walkable cities that reduce the need for cars. 

Green spaces are incorporated to absorb CO2 and improve air quality. Overall, the goal is to create buildings and cities that are not just carbon neutral but actively beneficial to the environment.
