PREAMBLE
It is an overview of the initiatives taken by Government of
Pakistan and Pakistan Civil Aviation Authority to mitigate
environment impacts of Aircraft and Aerodrome Operations on
safety and occupational health by:
 Minimizing the load of effluents and emissions from
aviation activities;
 Noise pollution control measures;
 Emphasis on use of Alternate resource of energy;
 Waste management;
 Waste water treatment and its reuse;
 Greater reliance on LED technology;
 Conduct of Environmental Impact Assessment (EIA) for
new Projects; and
 Focus on Resource Conservation & Environmental issues
associated with CAA, which can be controlled and directly
managed.

NATIONAL LEGISLATION – ENVIRONMENTAL
PROTECTION
 In order to meet international obligations and a service to humanity
as well as national interest:
 Pakistan Environmental Protection Act 1997 was promulgated on
December 3, 1997 to provide for the protection, conservation,
rehabilitation and improvement of the environment for the prevention
and control of pollution and promotion of sustainable development.
 National Environmental Policy was issued by the Ministry of
Environment, Government of Pakistan in 2005.
 National Environmental Quality Standards have been established
and approved by the Pakistan Environmental Protection Council.
 The above Legislation, Policy and Standards provided the tool to
PCAA for Compliance of relevant SARPs and its enforcement.

INITIATIVES OF PCAA
 PCAA as a policy has initiated the assessment of existing
international airports with regard to noise and aircraft engine
emissions. For this purpose following actions are in hand:
 Quality Safety and environment:
 Process to obtain ISO 9001, 14001 and OHSAS 18001 has
been initiated.
 Noise Control:
 Equipment for noise level monitoring have been procured and
plans to perform annual noise surveys are under preparation.
This will lead to noise control measures.
 Areas having noise level over 85 db at a distance of 7.5 m
from the source shall be designated as high noise areas.
Relevant signage is in the process of installation in the high
noise areas.

INITIATIVES OF PCAA (contd..)
 Energy conservation:
 Power factor improvement plants have been installed at
major international airports for efficient and losses-free
power consumption for conservation of energy.
 The revolutionary concept of power co-generation system
has been conceived and assessed for adoption in CAA.
Preliminary work was carried out in collaboration with
experts.
 This mechanism of power generation recovers waste heat
from power turbines and utilizes the same for airconditioning thereby increasing the efficiency, curtailing
power generation cost & impact on environment.
 An ADP scheme included for establishment of cogeneration power plant at JIAP Karachi.

Energy conservation:
Solar power aeronautical ground lighting systems for
remote aerodromes is being planned. Initially one
system is being procured. After the evaluation of its
benefits and commercial viability more systems will be
considered for other airports.
Establishment of proto type renewable energy power
plant has also been included in the development plans.
Installation of soft starters and variable frequency drive
at suitable electric loads is also part of development
plans. It will curtail power consumption of heavy
electric load by streamlining the supply current on
startups and during continuous operations.

 Oil and chemical spill control:
Plans to promote awareness about hazards associated
with oil and chemical spillage and preventive measures to
guard against such occurrences are being prepared for
implementation.
 Air pollution control:
 Reduction of track miles by rationalization of ATS routes
is being given due consideration to reduce air pollution. 3
ATS routes i.e. M875, L509 and N893 have been
established resulting in reduced flying time by 7, 6 and 9
minutes respectively. This lead to reduction of CO2 by 13
mkg, 10 mkg, and 7mkg per annum.

 Solid waste management:
 A process of developing and implementing a procedure
which defines the methodology to identify, manage,
separate hazardous and non-hazardous waste and its
disposal in an environmentally safe manner has been
initiated. The waste management has been described in
the following figure;
most
favoured
option
prevention
minimization/reduction
reuse
recycling
least
favoured

energy recovery
disposal

 Water conservation:
 A mega project worth billion of rupees have been
launched by the Government of Pakistan to reduce the
adverse impact on maritime life by treating waste water
of Karachi before its fall into the Arabian Sea.
 Pakistan CAA has planned to reduce wasteful usage of
water by 10%.
 A pilot project has also been planned to utilize waste
water stream passing through JIAP to cater for
horticulture needs of airport thereby decreasing the load
on scarce natural resource.

 Environmental friendly new projects
 As a policy, due consideration is being given to
environmental protection in the new airport projects.
 New Islamabad international Airport design and facilities
have been planned keeping in view all environmental
aspects. The concerned agencies and stakeholders have
been taken on board in the planning stages and
development process.

FUTURE PLANS
PCAA is aiming to transform into Environmental Friendly Eco
Organization. In this regard we intend to work in the following
areas:







Keeping in view the intense load on scarce national water
resources, CAA intends to explore Rain water harvesting at
different airports;
Promotion of Co generation;
Promotion of means to use renewable energy;
Improvement in waste prevention, minimization, reuse; recycling,
energy recovery and disposal;
Ensure Engine testing Noise Mitigation;
Development of Noise Mitigation Embankments;
Conversion of organic refuse into compost;

Pakistan Civil Aviation Authority
FUTURE PLANS (contd..)

Work with airline operators in reducing aircraft emission as
well as aircraft noise by sharing best practices like:
 Selection of fuel efficient altitudes;
 Selection of approach flap settings in a way that would reduce
resistance and thereby, fuel consumption, noise and cost as
well;
 Reduction of reverse thrust after touch down, where possible.
 Engine shutdowns to reduce fuel consumption and emissions
during taxiing;
 Fuel planning to ensure that the aircraft is not carrying any
access weight;
 Promotion of use of Ground Power Units (GPU) instead of
Auxiliary Power Units (APU) which will enable us to reduce
Aircraft Noise and emissions by 90% at international airports.
 Introduction of low pollution vehicles.
