Prix du carboneLe prix du carbone est un outil économique destiné à intégrer (internaliser) dans les prix de marché les coûts cachés (externalités) des dommages causés par les émissions de gaz à effet de serre, afin d'orienter les décisions des agents économiques vers des solutions à bas contenu en carbone. La forme la plus simple sous laquelle peut se matérialiser le prix du carbone est la taxe carbone ; une forme plus complexe est le système de quotas carbone (ou droits d'émission) qui peuvent s'échanger sur un marché du carbone.
Productivity (ecology)In ecology, the term productivity refers to the rate of generation of biomass in an ecosystem, usually expressed in units of mass per volume (unit surface) per unit of time, such as grams per square metre per day (g m−2 d−1). The unit of mass can relate to dry matter or to the mass of generated carbon. The productivity of autotrophs, such as plants, is called primary productivity, while the productivity of heterotrophs, such as animals, is called secondary productivity.
Low-carbon dietA low-carbon diet is a diet with low greenhouse gas emissions. Choosing a low carbon diet is one facet of developing sustainable diets which increase the long-term sustainability of humanity. It is estimated that the food system is responsible for a quarter to a third of human-caused greenhouse gas emissions. Major tenets of a low-carbon diet include eating a plant-based diet, and in particular little or no beef and dairy. A 2014 study into the real-life diets of British people estimated their greenhouse gas footprints in terms of kilograms of carbon dioxide equivalent per day: 7.
Mangrove restorationMangrove restoration is the regeneration of mangrove forest ecosystems in areas where they have previously existed. The practice of mangrove restoration is grounded in the discipline of restoration ecology, which aims to “[assist] the recovery of resilience and adaptive capacity of ecosystems that have been degraded, damaged, or destroyed”. Since environmental impacts are an ongoing threat, to successfully restore an ecosystem implies not merely to recreate its former condition, but to strengthen its capacity to adapt to change over time.
