Abstract

This article proposes a conceptual model for integrating and categorizing urban projects aimed at achieving carbon neutrality. This model comprises five interconnected levers: energy efficiency, renewable energy production and consumption, electrification of end use, circular economy, and CO 2 ensnaring (capture). Each lever encompasses projects and initiatives capable of directly or indirectly capturing urban CO 2 and accelerating the reduction of greenhouse gas emissions. These levers are interlinked, providing a road map for constructing a coherent and sustainable municipal model. Referred to as the “5-E levers”, this conceptual framework derives its name from the fact that all levers begin with the letter “E”, facilitating memorization and dissemination among policymakers.
