The Paris Agreement reaffirms the goal to limit global temperature increase to below 2°C above pre-industrial levels, with a secondary aggressive target of limiting that increase to 1.5°C. Many governments and thousands of corporations having since committed to significantly reducing greenhouse gas emissions by 2030 and being carbon neutral by 2050.
Carbon offsets are generated from any activity that either prevents or reduces carbon emissions (such as renewable energies or methane capture technology) or improves carbon sequestration (such as regenerative agriculture, or reforestation and conservation of forested lands, or direct carbon capture technology).
Carbon credits are effectively a measurable net benefit from an activity versus the status quo. Their units are measured in metric tonnes of CO2e, meaning one carbon credit is equal to one metric tonne of CO2e emission reduction.
