The planet has a natural way of ensuring atmospheric balance. Emitting CO₂ from wetlands and forest fires, the Earth absorbs it again through trees, soil and oceans. But unfortunately, an unsustainable growth in the population, along with the industrial revolution and the continued exploitation of natural resources, have all contributed to the disruption of this natural cycle.
Modern practices have resulted in excessive amounts of greenhouse gases being pumped into the atmosphere, destroying our natural carbon sinks. This has made it harder for the Earth to heal itself. By investing in carbon offsetting projects, individuals and businesses can keep their carbon footprint low. In addition, they will be supporting carbon sequestration projects, which are largely located in developing economies.
If carbon emissions are released through business activity, these companies can purchase carbon offset credits to balance out their emissions elsewhere in the world. Essentially making that activity carbon neutral.
Offsetting projects fall into 3 main categories:
- Emissions removal – These projects actively remove or sequester carbon, usually through the planting of trees or mangroves which are natural absorbers of carbon.
- Emissions avoidance – These projects avoid greenhouse gas emissions that would otherwise be released into the atmosphere. For example, nature conservation, renewable energy, and the distribution of efficient cookstoves in developing countries.
- Emissions capture – Similar to emissions removal, although not nature-based. For example, capturing methane from wastewater or landfills.
