 - An organization can call itself Carbon Neutral when its total emissions are matched by the total of its emissions offsets through carbon reduction projects
 - Net zero aims to eliminate emissions and only offset the residual emissions that you cannot eliminate to reach the 1.5°C target set by the Paris Climate Agreement.
 - The SCI is carefully designed so that eliminating emissions, through energy efficiency, hardware efficiency and carbon awareness is the only way to reduce the score. Together with a separate neutralization strategy, it can form the basis of a net-zero strategy for an organization.
-- When organizations set a target of 100% renewable power, they can either be “matched by” vs. “powered by” renewables, where “powered by” means the electrons flowing into your device can only come from renewable sources. This can be achieved by purchasing RECs as part of a PPA.
