Download as PPTX, PDF0 likes145 views
The document discusses implementation challenges for achieving 1.5°C pathways, emphasizing that the global roll-out of successful policies could help reach both 2°C and 1.5°C targets. It evaluates various scenarios regarding disruption, speed, scale, and efficiency to assess the feasibility of these pathways. Recommendations include reducing emissions through energy efficiency and adopting renewable energy while implementing moderate carbon pricing.
