Utsläppshierarki

Utsläppshierarki refers to a prioritized approach for reducing emissions, particularly in environmental policy and corporate sustainability strategies. The core principle is to tackle emissions in a specific order, starting with the most effective and preferable methods.

The hierarchy typically begins with avoidance. This means preventing emissions from occurring in the first place by redesigning processes, choosing less emissive materials, or altering behaviors. Following avoidance, the next step is reduction. If emissions cannot be entirely avoided, the goal is to minimize them as much as possible through efficiency improvements and technological advancements.

If emissions remain after avoidance and reduction efforts, substitution is considered. This involves replacing high-emission sources or substances with lower-emission alternatives. For example, switching from fossil fuels to renewable energy sources.

The final stages of the hierarchy often involve treatment or capture, where unavoidable emissions are treated to reduce their harmful impact or captured for storage or reuse. This is generally considered a less desirable option than avoidance or reduction, as it deals with the consequences of emissions rather than preventing them.

The concept of an emissions hierarchy is a guiding framework to promote a systematic and comprehensive strategy for achieving climate goals and reducing environmental impact. It encourages a proactive and preventative mindset in tackling pollution.
