ABSTRACT
The LIFTS model extends the concept of planetary limits by proposing the definition of maximum environmental impact budgets for which the company is responsible, for the entire life cycle of its products and services. This approach is based on the idea that if all companies respect the budgets allocated to them, then, on a global scale, the corresponding planetary limits could also be respected. The LIFTS model is thus conceived as a relay for an effort that must be made on a global scale. The notion of maintaining natural capital is embodied in respect for planetary limits, with an allocation mechanism at company level to assess individual participation.
To understand the calculatory and accounting mechanics associated with this idea, this chapter presents the LIFTS model management philosophy, i.e., the science of the earth system, on which the understanding and calculation of planetary boundaries is based. The planetary limits are then defined and presented individually, with the interactions they have with each other. Finally, calculation methods are proposed for allocating environmental resource budgets on a corporate scale. This chapter concludes with a discussion of the conditions for the success of such a methodological proposal.
