How to Implement a Sustainable Mobility Allowance in Your Company: Step-by-Step Guide

Adopted as part of the ecological transition, the Sustainable Mobility Allowance (SMA) enables companies to support more sustainable commuting options for employees. It aims to reduce reliance on single-occupancy vehicles while encouraging greener alternatives.

This program addresses two key challenges: lowering the carbon footprint of daily commutes and improving employees’ purchasing power by reducing transportation costs. It also contributes to better workplace well-being.

More and more organizations are integrating the SMA into their HR and ESG strategies to meet employee expectations and environmental goals. Easy to implement and tax-efficient, it can be adapted to companies of all sizes and industries.

In this guide, discover eligible transport options, eligibility criteria, and the key steps to successfully implement the program.

Understanding the Sustainable Mobility Allowance (SMA)

What is the SMA?

The Sustainable Mobility Allowance (SMA) is a program designed to encourage employees to use environmentally friendly transportation for their commute. It allows employers to cover part or all of the costs associated with sustainable mobility options such as cycling or carpooling.

By reducing the financial burden of alternative transport, it helps shift behaviors away from individual car use.

Key objectives

The SMA serves a dual purpose.

First, it reduces greenhouse gas emissions linked to commuting, which represent a significant share of overall emissions.

Second, it improves employees’ purchasing power while promoting healthier and less stressful commuting habits.

Legal and regulatory framework

The SMA is part of broader mobility and environmental policies and applies to both private and public sectors, with specific rules depending on the context.

It benefits from a favorable tax framework: amounts paid are exempt from social contributions and income tax within defined limits.

Flexible, it can be implemented through a collective agreement or a unilateral employer decision.

Why implement the SMA in your company?

Encouraging cycling, carpooling, and shared mobility significantly reduces emissions related to commuting.

Improve employee well-being

Sustainable transport options are often faster in urban areas and contribute to better physical and mental health.
