Carbon Neutral vs Net Zero
Two terms that are often used interchangeably by the politicians, businesses, scientists and experts driving the climate conversation. Yet there’s some key differences which are important to understand.
Amidst the rising discourse on climate change, understanding the terminology is crucial for informed conversations. The terms "net zero" and "carbon neutral" have become commonplace, but do they signify the same concept? While they share the ultimate goal of removing harmful emissions from the atmosphere, a closer look reveals distinctions in scale and emission types.
Differentiating Carbon Neutral and Net Zero
Net Zero:
Definition: The removal of greenhouse gases (GHGs), like CO2, methane, or sulfur dioxide, from the atmosphere equals the emissions generated by human activities.
Emission Trajectory: Typically follows a specific trajectory, such as a target of 1.5°C (34.7°F), with a focus on GHG sequestration for residual emissions.
Carbon Neutrality:
Definition: GHG emissions are offset, encompassing a broader range of activities, including emissions avoidance, without specifying a reduction trajectory.
Reporting Boundary: Less prescriptive, encouraging but not mandating the inclusion of wider value chain (Scope 3) emissions.
Understanding Carbon Neutrality
Businesses often aim for carbon neutrality by neutralizing emitted CO2 through investments in "carbon sinks" like forests or oceans. These sinks absorb and store more carbon than they emit, creating a balanced carbon equation. Initiatives typically involve reducing emissions first, followed by investments in visible offset programs.
Individual Contributions
Carbon neutrality isn't exclusive to businesses; individuals can contribute by making sustainable lifestyle choices, such as using public transport, minimizing food waste, recycling, and monitoring home energy usage.
Exploring Net Zero
Net zero expands on the principles of carbon neutrality, encompassing all greenhouse gases emitted into the atmosphere. Achieving net zero requires equivalence between emitted and removed greenhouse gases, involving global collaboration from governments, private sectors, and third sectors.
Global Implications
Research indicates that embracing carbon neutrality is advantageous for businesses, offering long-term benefits through operational efficiencies, tax reductions, and environmental protection. The collaborative efforts required for net zero align with a sustainable future for all stakeholders.
