Environmental Aspects & Impacts: The Beginner Guide, With Examples

An environmental aspect is what the site does; the environmental impact is what the doing does to the environment. The aspect is the activity, the emission, and the resource; the impact is the air, the water, the soil, and the biodiversity. The aspect-impact chain is the logic of the environmental management, and this article is the chain in working form: the aspect, the impact, the difference, the identification, and the register.

The bottom line: An environmental aspect is what the site does (the activity, the emission, the resource); the environmental impact is what the doing does to the environment (the air, the water, the soil, the biodiversity). The aspect is the cause, the impact is the effect, and the chain is the logic of the ISO 14001 (the clause 6.1.2) and the environmental permit.

The aspect: the what the site does

An environmental aspect is the element of the activity that interacts with the environment: the activity, the process, the service, and the doing. The aspect is the line, and the line is the interaction — the aspect is the emission, the resource, and the waste that is the site does.

The aspect is the example: the energy use (the electricity, the gas), the water use (the process, the cooling), the waste (the general, the hazardous), and the emission (the air, the water). The aspect is the what, and the what is the site does.

The impact: the what the doing does

An environmental impact is the effect of the aspect on the environment: the air, the water, the soil, and the biodiversity that is the changed. The impact is the result, and the result is the effect — the impact is the one the environment does after the aspect.

The impact is the example: the air pollution (the emission, the VOC, the particulate), the water pollution (the discharge, the BOD, the TSS), the soil contamination (the spill, the leachate), and the resource depletion (the energy, the water). The impact is the what-after, and the what-after is the environment becomes.

The difference: the aspect vs the impact, with examples

The difference is the chain, and the chain is the aspect to the impact. The aspect is the activity (the what the site does); the impact is the effect (the what the doing does to the environment). The aspect is the cause, the impact is the result, and the result is the environment.

The chain is the logic: the aspect → the impact. The energy use (the aspect) is the carbon emission (the impact). The solvent use (the aspect) is the VOC emission (the impact). The waste oil (the aspect) is the soil and the groundwater (the impact). The chain is the one the ISO 14001 reads, and the one the permit reads.

Aspect (the site does)Impact (the environment becomes)
Energy use (the electricity, the gas)Greenhouse gas emission (the climate change)
VOC emission (the solvent, the paint)Air pollution (the smog, the health)
Water discharge (the process water)Water pollution (the river, the ecosystem)
Spill (the fuel, the chemical)Soil and water contamination (the land, the groundwater)
Waste to landfill (the solid)Landfill impact (the land, the methane)
Noise (the plant, the traffic)Noise pollution (the community, the health)
Habitat removal (the site, the clearing)Biodiversity loss (the species, the habitat)

How to identify the aspects and impacts

The identification is the walk, and the walk is the activity by the activity. Walk the process: the raw material in, the process, the product out, the waste, the energy, and the water. The walk is the aspect, and the aspect is the line.

Ask the three: what does the site emit (the air, the water, the noise)? What does the site consume (the energy, the water, the raw material)? What does the site dispose (the waste, the general, the hazardous)? The three are the aspect, and the aspect is the identified one.

The register, and the ISO 14001

The register is the line, and the line is the document. The environmental aspect and impact register is the document: the aspect, the impact, the significance, the control, the regulatory, and the review. The register is the ISO 14001 clause 6.1.2, and the one the environmental permit reads.

The ISO 14001 is the system, and the system is the register: the aspect-impact is the planning (the 6.1.2), the control is the operation (the 8), and the review is the performance (the 9). The register is the chain in the document, and the document is the one the auditor opens first.

Need the sign-off, not just the article?

The article is the preparation; the sign-off is the professional. For the statutory assessments, the audits, the ISO 45001 implementation and the training that comes with them, ask Muhammad Umer — 8+ years across Iraq, KSA and Pakistan, and the programme runs through umer-hse.pro.

Common questions

Environmental Aspects & Impacts — answered

What is the difference between an environmental aspect and an impact?

The aspect is what the site does (the activity, the emission, the resource) — the cause. The impact is what the doing does to the environment (the air pollution, the water pollution, the soil contamination) — the effect. Example: the aspect is the VOC emission from the paint booth; the impact is the air pollution. The chain is the aspect to the impact.

What are examples of environmental aspects?

The energy use (the electricity, the gas, the fuel), the water use (the process, the cooling, the domestic), the waste (the general, the hazardous, the sludge), and the emission (the air, the water, the noise, the vibration). The aspect is the activity, and the activity is the site does.

What are examples of environmental impacts?

The air pollution (the VOC, the particulate, the NOx), the water pollution (the BOD, the TSS, the oil), the soil contamination (the spill, the leachate), the resource depletion (the energy, the water), and the biodiversity loss (the habitat, the noise). The impact is the effect, and the effect is the environment becomes.

What is an environmental aspect and impact register?

The document that holds the chain: the aspect, the impact, the significance, the control, the regulatory, and the review. The register is the ISO 14001 clause 6.1.2 (the environmental aspect), and the one the environmental permit reads. The register is the chain in the document, and the document is the one the auditor opens first.

How do you identify environmental aspects?

The walk, and the three questions. Walk the process: the raw material in, the process, the product out, the waste, the energy, and the water. Ask: what does the site emit (the air, the water, the noise)? What does the site consume (the energy, the water)? What does the site dispose (the waste)? The three are the aspect, and the aspect is the identified one.

What is the difference between aspect, impact, and compliance obligation?

The three are the chain plus the law. The aspect is the what the site does (the cause); the impact is the what the doing does (the effect); the compliance obligation is the law that is the aspect and the impact (the emission limit, the discharge consent, the waste duty). The aspect-impact is the 6.1.2; the compliance obligation is the 6.1.3 — the two are the planning, and the planning is the ISO 14001.
