Sustainable Behavior in Climate Pledges: An Analysis of Top Emitters’ Strategies

The paper evaluates the integration of pro-climate behavior changes in the NDCs of the top 20 emitting countries. It identifies a gap between the emissions reduction potential of certain behaviors—particularly in the food sector—and their actual inclusion in national pledges. The analysis reveals that countries primarily rely on infrastructure and service improvements to drive behavior change, while underutilizing incentives and personalized information.

• Of the nine identified Priority Practices, only three are consistently included in at least half of the NDCs of the 20 highest-emitting countries. These practices focus on the energy and mobility sectors: promoting electric or hybrid vehicles, increasing public transport use to replace gasoline or diesel vehicles, and reducing household energy use through insulation or energy-efficient appliances.
• There is a misalignment between the emissions reduction potential of behavior changes and their presence in NDCs. Specifically, food-related behavior changes, such as reducing consumer food waste and adopting sustainable diets, offer high GHG reduction potential but are the least frequently considered in NDCs.
• Countries predominantly use infrastructure and service improvements to promote behavior change, while failing to leverage other tools such as incentives or personalized information. For instance, while many plan to install electric vehicle charging stations, few mention tax breaks for vehicle purchases. Only two analyzed nations use a combination of all three behavior change tools for electric or hybrid vehicle adoption.
