Even though carbon-neutral and carbon-free sound pretty similar they have completely different meanings.
Carbon Neutral, also called carbon neutrality, term used to describe the action of organizations, businesses and individuals taking action to remove as much carbon dioxide from the atmosphere as each put in to it. The overall goal of carbon neutrality is to achieve a zero carbon footprint. For example, a business may plant trees in different places around the world to offset the electricity the business uses. This practice is often called carbon offset or offsetting. The carbon neutral concept may be extended to include other greenhouse gases (GHG) measured in terms of their carbon dioxide equivalence—the impact a GHG has on the atmosphere expressed in the equivalent amount of CO2.
Carbon free is a term that is quite literally what it says. It is a term that describes the actions of organisations, businesses and individuals taking action to use or try to use 100% renewable energy to satisfy their power needs. By using carbon free power solutions, like solar, hydroelectric, wind, geothermal, biological, hydrogen and ocean energy, the carbon footprint is significantly reduced. By switching to carbon free power sources, we can reduce the global carbon footprint and significantly reduce climate change. Companies like EcoCloud360 provide services that are completely carbon free.
