What is carbon neutrality?

Carbon neutrality is a situation in which CO2 emissions associated with human activity on a global scale are offset by the ability of ecosystems to absorb these carbon emissions. Achieving carbon neutrality is therefore not about zero CO2 emissions, but about reaching a balance point between the amount of greenhouse gas emissions emitted in the world and the Earth's ability to capture and store carbon dioxide. IPCC (The Intergovernmental Panel on Climate Change) reiterated this in its latest report: limiting global warming to 1.5°C will require achieving "carbon neutrality" by 2050.
