There are several methodologies and techniques that can be used to measure the carbon footprint of last-mile logistics. Here are a few examples:

1. Emission Factors: This approach is based on using emission factors that are published for different modes of transportation, such as delivery vans or bicycles. Emission factors are used to estimate the amount of CO2 emissions based on the distance travelled and the mode of transportation used.

2. Life Cycle Assessment (LCA): LCA is a technique that evaluates the environmental impact of a product or service throughout its entire life cycle, from raw material extraction to disposal. LCA can be used to identify the carbon footprint of last-mile logistics by considering the emissions associated with the production, distribution, use, and end-of-life of the vehicles and equipment used for delivery.

3. GPS Tracking: GPS tracking technology can be used to track the routes and distances travelled by delivery vehicles. This data can be combined with emission factors to estimate the amount of CO2 emissions generated during the last-mile delivery process.

4. Simulation Models: Simulation models can be used to estimate the carbon footprint of last-mile logistics by simulating the delivery process and estimating the energy consumption and emissions associated with each step.

5. Carbon Accounting Tools: There are a number of carbon accounting tools available that can be used to estimate the carbon footprint of last-mile logistics. These tools use data inputs such as distance, mode of transportation, and fuel consumption to calculate the carbon emissions associated with last-mile delivery.

Overall, the choice of methodology or technique will depend on the specific context and data availability. It may be necessary to use a combination of approaches to obtain a comprehensive and accurate estimate of the carbon footprint of last-mile logistics.
