Carbon Neutral
Achieving net-zero carbon dioxide emissions by balancing the amount of CO2 released into the atmosphere with an equivalent amount removed or offset. This can be achieved through a combination of emission reduction and carbon offsetting.
Carbon neutrality has become a major corporate and national goal. Over 70 countries have pledged to reach carbon neutrality by 2050, and hundreds of major companies have made similar commitments. But the term has also attracted criticism for its potential to be misleading.
How It Works
An entity becomes carbon neutral by first measuring its total emissions, then reducing them as much as possible, and finally offsetting the remaining emissions. Offsets typically involve investing in projects that absorb or prevent CO2 emissions elsewhere, such as reforestation, renewable energy projects, or methane capture from landfills.
Carbon Neutral vs Net Zero
While often used interchangeably, these terms have important differences. Carbon neutral usually refers only to CO2 and allows heavy reliance on offsets. Net zero is more stringent, typically covering all greenhouse gases and requiring that the majority of emission reductions come from actual cuts rather than offsets. The Science Based Targets initiative (SBTi) requires companies to reduce emissions by at least 90% before using offsets for the remaining 10%.
The Offset Controversy
Carbon offsets have come under scrutiny. A 2023 investigation found that over 90% of rainforest carbon offsets approved by the leading certifier Verra were likely worthless. Critics argue that offsets can create a "license to pollute" rather than driving real emission reductions. The most credible approach is to prioritize direct emission cuts first and use high-quality, verified offsets only for truly unavoidable emissions.
Related Terms
Carbon Footprint
The total amount of greenhouse gases (primarily CO2) generated by human actions, measured in tonnes of CO2 equivalent per year. It includes direct emissions from driving and heating, and indirect emissions from the production of goods and services you consume.
Greenwashing
The practice of making misleading or unsubstantiated claims about the environmental benefits of a product, service, or company. It makes something appear more eco-friendly than it actually is to capitalize on growing consumer demand for sustainability.
Net Zero
The state where the total amount of greenhouse gases emitted is balanced by the total amount removed from the atmosphere. Unlike carbon neutral, net zero typically requires deep emission reductions (90%+) before offsets are used for remaining emissions.
