Environmental Management
Environmental Management is the planned regulation of human activities to minimise adverse impacts on the environment while sustaining benefits to society. It combines science, law, economics and engineering with corporate and community practice.
A structured framework of policies, procedures, audits and review by which an organisation systematically identifies its environmental impacts, sets objectives, allocates responsibilities, and continually improves performance. ISO 14001 (first issued 1996, current 2015) is the international standard for EMS.
Core tools
1. Environmental Impact Assessment (EIA)
EIA is a systematic, pre-decision evaluation of likely environmental consequences of a proposed project. Pioneered by the US National Environmental Policy Act (NEPA) 1969, EIA is now used in over 190 countries.
Typical stages:
- Screening — does the project need EIA?
- Scoping — identify key impacts and alternatives.
- Baseline study — biophysical and socio-economic.
- Impact prediction and evaluation.
- Mitigation and management plan (EMP).
- Public consultation and review.
- Decision and monitoring.
In Pakistan, Section 12 of the Pakistan Environmental Protection Act 1997 makes EIA/IEE mandatory; Pak-EPA Regulations 2000 list categories.
2. Strategic Environmental Assessment (SEA)
SEA applies the EIA logic to policies, plans and programmes rather than individual projects — e.g. a national energy plan.
3. Life-Cycle Assessment (LCA)
Cradle-to-grave evaluation of a product's environmental impact across raw materials, manufacture, distribution, use and disposal. Governed by ISO 14040/14044.
4. Environmental auditing
Periodic, documented verification that operations comply with policies, regulations and standards.
5. Economic instruments
- Pollution taxes (carbon tax, effluent charge).
- Cap-and-trade schemes (EU ETS, the world's largest carbon market since 2005).
- Subsidies for renewables; subsidy reform for fossil fuels.
- Payments for Ecosystem Services (PES).
- Tradable resource permits (e.g. fisheries ITQs).
- NEPA 1969 (USA) is the origin of formal EIA.
- ISO 14001 is the international EMS standard.
- Pakistan EIA framework: PEPA 1997 (Section 12) + Pak-EPA Regulations 2000.
- SEA evaluates policies/plans; LCA evaluates products.
- Polluter Pays and Precautionary principles underpin most regulatory tools.
Integrated Water Resources Management (IWRM)
The Global Water Partnership defines IWRM as the coordinated development of water, land and related resources to maximise welfare equitably without compromising ecosystems. Key elements:
- River-basin scale planning.
- Stakeholder participation.
- Conjunctive use of surface and groundwater.
- Demand management (efficient irrigation, metering).
In Pakistan, IWRM is operationalised partly through the Indus River System Authority (IRSA), established under the 1991 Water Apportionment Accord among the four provinces, and through the Water Apportionment Authority in Punjab.
Solid Waste Management Hierarchy
| Priority | Strategy |
|---|---|
| 1 | Prevent / reduce |
| 2 | Reuse |
| 3 | Recycle |
| 4 | Recover (energy) |
| 5 | Dispose (landfill, incineration) |
This is the 3R+ hierarchy (Reduce, Reuse, Recycle, sometimes Recover, then Dispose).
Hazardous waste
- Basel Convention (1989) controls transboundary movement of hazardous waste.
- Stockholm Convention (2001) targets persistent organic pollutants (POPs) — the "Dirty Dozen" plus extensions.
- Rotterdam Convention (1998) — Prior Informed Consent for trade in hazardous chemicals.
Pakistan is party to all three "BRS" conventions.
Environmental institutions in Pakistan
- Ministry of Climate Change and Environmental Coordination (federal).
- Pak-EPA and provincial EPAs (Punjab, Sindh, KP, Balochistan, GB, AJK).
- National Disaster Management Authority (NDMA) — Act 2010.
- Provincial Disaster Management Authorities (PDMAs).
- Pakistan Council of Research in Water Resources (PCRWR).
- Global Change Impact Studies Centre (GCISC).
Disaster Risk Management (DRM)
The Sendai Framework for Disaster Risk Reduction 2015–2030 (UN) succeeded the Hyogo Framework. It has four priorities: understand risk, strengthen governance, invest in resilience, enhance preparedness.
Examiners often ask candidates to compare EIA, SEA and LCA. Remember the object of each: EIA = a project, SEA = a policy/plan/programme, LCA = a product. Cite PEPA 1997 § 12 for the Pakistani EIA mandate, and ISO 14001:2015 for EMS — that level of detail wins marks.
Public participation and the Aarhus principle
UNECE's Aarhus Convention (1998) rests on three pillars: access to information, public participation, access to justice in environmental matters. Pakistan is not a party, but the spirit of these pillars is reflected in domestic right-to-information laws and PEPA notification provisions.
Sustainable Development Goals as a management frame
SDG 6 (water), SDG 7 (clean energy), SDG 11 (cities), SDG 12 (consumption/production), SDG 13 (climate), SDG 14 (life below water), SDG 15 (life on land) — collectively define the global environmental management agenda to 2030.
