Environment : Terms

Limited carbon budget: an upper bound to the amount of GHGs that can be pumped into the atmosphere while still maintaining a stable climate

Delayed effects: it will take several decades for impacts from GHGs in the atmosphere to manifest
Asymmetrical impacts: most impact will be on poor countries like sub-Saharan Africa, small islands se in the Pacific and Indian Ocean and deltaic regions of South and S E Asia, Egypt  and China
Polluter’s Pay Principle : The ‘polluter pays’ principle basically works on the premise that those responsible for higher pollution—whether it is an individual factory or a country—should bear the costs of managing it to prevent damage to health or the environment.
For instance, a factory that produces a potentially poisonous substance as a byproduct of its activities is usually held responsible for its safe disposal.
