Challenges faced by engineers on
Environmental issuses in Maldives

Major challenges include
• Depletion of nonrenewable resources such as fossil fuels and minerals
• Inadequate management of industrial wastes and effluents, resulting
in impacts to human health and quality of the biotic environment
• Depletion of agricultural lands occurs due to urban sprawl. High yield
practices may increase land and water pollution
• Deforestation and inadequate availability of carbon sinks contributing
to increased atmospheric CO2 and subsequent climate change

Environmental impacts resulting
from various human activities

Pollution of (a) water, (b) atmosphere,
and (c) land.
• Loss and degradation of soil quality due to the use of pesticides, insecticides,
fertilizers, and other soil amendments
• Increased use of natural resources by mining and forestry activities and energy
production
• Increased greenhouse gas and other emissions, leading to acid rain and climate
change that increases severe weather occurrences, water levels, and erosion of
coastal areas among other effects
• Biological magnification of pollutants by plants, aquatic organisms, and animals

To achieve a more sustainable
society, various practices
• Protection of the soil, a natural resource that is the basis of at least
90% of the production of food, energy, and materials
• Development of sustainable remediation and practices for
environmental management
• Development of renewable resources to replace nonrenewable ones
• Development of protocols and procedures for technological
development and new social attitudes to mitigate and adapt to
climate change, in particular

• Renewable energy sources include the use of solar, hydro, wind, and
biomass, while fossil fuels (crude oil, natural gas and coal) are
considered as nonrenewable
• Pollutants such as sulfurous oxides (SOx), nitrous oxides (NOx), and
particulate matter are produced from the combustion of fossil fuels
and biomass.
• These then can be converted to acid rain and ground level ozone in
the atmosphere
• Other impacts include flooding required by hydrodams for
hydroelectricity generation that destroys habitats and alters water
flows.

• Nuclear power has significant waste disposal issues and problems due
to plant failures as in Japan.
• Solar panel production requires significant amounts of rare metals
and waste production
• Biomass fuels can lead to deforestation if wood is used as the
feedstock.
• 8.2 million premature deaths are caused each year due to unhealthy
environments, air pollution in particular

Industries can impact the
environment as follows
(a) Resource extraction and (a) the metal mining industries;
(b) industries involved in extraction and processing of potash, clay
minerals, phosphates;
(c) the industries for extraction of aggregates, sand and rock for
building material production; and
(d) extraction of fossil fuels (natural gas, oil, oil sands, and coal) and
uranium for the nuclear power industry. 2. Utilization of soil for
agriculture and forest industries. 3. Water, groundwater, and aquifer
use for hydroelectricity generation and other industries.

Anthropogenic sources of
contaminants
• (a) various industries such as mining, manufacturing and processing,
and resource exploration and exploitation and
• (b) human activities such as construction of buildings and
infrastructure, disposal and land management of waste, agriculture.

Drinking Water- Key Facts
• In 2017, 71% of the global population (5.3 billion people) used a safely managed drinking-water
service – that is, one located on premises, available when needed, and free from
contamination.
• 90% of the global population (6.8 billion people) used at least a basic service. A basic service is
an improved drinking-watersource within a round trip of 30 minutes to collect water.
• 785 million people lack even a basic drinking-waterservice, including 144 million people who
are dependent on surface water.
• Globally, at least 2 billion people use a drinking water source contaminated with faeces.
• Contaminated water can transmit diseases such diarrhoea, cholera, dysentery, typhoid, and
polio. Contaminateddrinking water is estimated to cause 485 000 diarrhoeal deathseach year.
• By 2025, half of the world’spopulation will be living in water-stressed areas.
• In least developed countries,22% of health care facilities have no water service, 21% no
sanitation service, and 22% no waste management service.

LIFE CYCLEASSESSMENT FOR SUSTAINBILITY
Introduction – LCA Process – Lifecycle Sustainability – LCA
Tools – Applications of LCA
https://youtu.be/_6xlNyWPpB8

Eco Design (eD). To design products considering all environmentalimpacts not only from the recycling perspective but
from any product stage perspective.
Green Development (GD). To develop manufacturing plans (Meta, Macro and Micro process) considering the
environmental impacts of manufacturing technologies.
Green (Sustainable) Manufacturing (GM). To manufacture using materials and processes that minimize environmental
impacts, conserve energy and natural resources, ensure safety for employees and society.
Sustainable Production and Logistics (SPL). To consider how mass production and outsourcing contribute to Green PLM.
Responsible Use and Maintenance (RUM). To define intelligentcontrol that will help in the supervision of product’s use
and maintenance in order to feedback metrics to ecodesign activities.
Product Social Response (PSR). Reduce, Reuse, retire and/or recycling of products in order to close the cycle.
https://youtu.be/-9JRowyICbo
In order to define the lifecycle we have established key competences for the Green Manufacturing Enterprise:

What is life cycle costing and how is it applied?
It is usually carried out in four phases:
1 Define a goal, scope and functional unit.
2 Inventory costs.
3 Aggregatecosts by cost categories.
4 Interpretresults.
Phase 1 Define a goal, scope and functional unit
• An LCC will define the goal of the study, a functional unit, specify system
boundaries, apply allocationprocedures, discount rates and so forth.
• It is also important to state the viewpoint of the life cycle actor (whether
supplier, manufacturer,user or consumer) during this phase.
• At this stage also, a cost breakdown structure (CBS) should be developed in
order to facilitate the consistent collection of data along the full life cycle and
which can also be aggregated along the life cycle.
• https://youtu.be/dtqFxoHk8w8

Phase 2 Inventory costs
• In Phase 2, costs are inventoriedon a unit process level.
• The level of aggregation may vary significantly over the life cycle and between differentunit
processes.
• Since more than one product is produced by most enterprises,the allocationof costs to each
product is required.
• For example, in the case of two metals produced at the same time, overhead costs can be
distributedto each metal proportionally to the incomes received by each metal, or the number of
working hours implied by the metal production, among others.

https://youtu.be/spjwQX-acnA

WHAT IS 1SO 14000…?
ISO 14000 is a series of environmental management standards
developed and published by the International Organization for
Standardization ( ISO ) for organizations. The ISO 14000 standards
provide a guideline or framework for organizations that need to
systematize and improve their environmental management
efforts.

WHY ISO 14000..?
 Reduces environmental liability
 Enhances public image and reputation
 Assures customers
 Satisfies investor criteria
 Reduces your consumption of materials and energy

 Includes evaluation of suppliers and review
of customer contracts.
 The goals of a quality system are generally
• quite clear
 Deals with the management of the
environmental effects of an organization
 Customers as well as
many additional
• stakeholders
 Include methods of
evaluating
• environmental impacts and systems
 The situation for environmental systems

PROCEDURE
 Top managementis responsible to establish environmental objectives on an annual basis.
 Plant/ Department managers involve operation staff in developing environmental objectives
for improvementin environmental performance.
 Each department manager is responsible to provide inputs and evaluate potential impacts in specific
functions.
 Manager makes preliminary evaluation of its environmental performance, and enlists primary
objectives.
 Progress towards the objectives/targets is reviewed at managementreview meetings and
communicatedto operational staff via bulletin boards.

ASPECTS OF ISO 14000
 Environmental Management System
 Environmental Auditing and related investigations
 Environmental Labels and Declarations
 Environmental Performance Evaluation
 Life CycleAnalysis & Terms and Definitions.

ISO 14000 FAMILY
A series of guidance documents and standards to help organizations address
environmental issues.
 14001: Environmental Management Systems
 14004: EMS general guidelines
 14010: Guidelines for EnvironmentalAuditing
 14011: Guidelines forAuditing of an EMS
 14012:Auditing - Qualification criteria
 14020: Environmental Labeling
 14030: Environmental Performance Evaluation (EPE)
 14040: Life-CycleAssessment (LCA)

14001: ENVIRONMENTALMANAGEMENT SYSTEMS
ISO 14001 is the specification standard that is a model for an
environmental management system.
 Systematic way of managing an organization’s environmental affairs
 Based on Plan-Do-Check-Act Model (PDCA)
 Focused on Continual Improvement of System
 Addresses immediate and long-term impact
of an products, services and processes on the
environment.
organization’s
 A tool to improve environmental performance

14004: EMS GENERAL GUIDELINES
 ISO 14004:2016 provides guidance for an organization on the establishment, implementation, maintenance
and improvementof a robust, credible and reliable environmental management system.
 This International Standard helps an organization achieve the intended outcomes of its environmental
management system, which provides value for the environment, the organization itself and interested
parties.
 the intended outcomes of an environmental management system include:
- enhancement of environmental performance;
- fulfilment of compliance obligations;
- achievementof environmental objectives.

14010 – 12 ENVIRONMENTALAUDITING
 Three standards actually cover the topic of environmental auditing. They are:
ISO 14010 - General Principles of Environmental Auditing
ISO 14011/1 - Audit Procedures - Part 1: Auditing of Environmental Management Systems
ISO 14012 - Qualificationcriteria for Environmental Auditors
 Other related standards are expected to be developed at a later times. For right now, we only need to
examine these three guideline standards for ISO 14001 to gain a basic understanding of how an
environmental management system (EMS) will be audited.

14030: ENVIRONMENTAL PERFORMANCE EVALUATION (EPE)
 An internal management process that provides information to
facilitate management decisions regarding an organization’s
environmental performance. This standard is an excellent companion
to ISO 14001:2015, which requires organisations to demonstrate an
improvement in environmental performance. These standards
provide powerful tools for organisations, giving them a means to track
their progress towards a more circular and sustainable economy.

14040: LIFE-CYCLEASSESSMENT (LCA)
LCA can assist in
Identifyingopportunities to improve the environmental performance of products at various points in
their life cycle,
Informingdecision-makers in industry, governmentor non-governmentorganizations (e.g. for the
purpose of strategic planning, priority setting, product or process design or redesign),
The selection of relevant indicators of environmental performance, including measurement
techniques,
Marketing (e.g. implementingan eco-labellingscheme, making an environmental claim, or producing
an environmental product declaration).

BENEFITS OF ISO 14000
 Helps organizations meet and maintain
regulatory and legislative requirements
 Minimizes the environmental impact of
products, activities, and resources.
 Promotes environmental awareness

BENEFITS OF ISO 14000
 Better conformance to environmental regulations,

What is the Forest Stewardship Council (FSC)?
Non-profit organization devoted to encouraging the
responsible management of the world’s forests.
Landowners and companies that sell timber or forest
products seek certification as a way to verify to consumers
that they have practiced forestry consistent with FSC
standards.
Consolidated Graphics has attained this certification
through Smart Wood and CDS is now an important part of that
chain.

 All products that are FSC-certified contain
wood or wood fibre from FSC-certified
forests, recycled material and/or controlled
wood.
 Wood – timber -Green Building ,
Musical Instrument
 Plywood - Green Building
 Furniture ,
 paper -, Printer , Handicarft

FSC and
environmental
organizations
Trusted environmental organizations that support and
encourage FSC certification include:
Greenpeace
National Wildlife Federation
The Nature Conservancy
Sierra Club and
World Wildlife Fund

FSC Vision Statement
FSC seeks a world where buyers of wood and paper are
empowered to make responsible choices through the use
of FSC certification. We strive to build trust in our
brand every day and thereby rebuild trust in the practice
of responsible forestry. By creating value in working
forests, we will create a marketplace that rejects
unsustainable and irresponsible forest products.

Principles and
Criteria
•FSC has developed a set of Principles and Criteria for forest
management that are applicable to all FSC-certified forests and
throughout the world.
•There are 10 Principles and 57 Criteria that address legal issues,
indigenous rights, labor rights, multiple benefits, and environmental
impacts surround forest management.
•The principals and criteria at www.fsc.org

Becoming Certified
•Forest Stewardship Council forest certification is a
voluntary market mechanism through which forests are
certified against a strict set of environmental and social
standards.
All producers and manufacturers along the supply chain
are certified to ensure that the final product bearing the
FSC logo actually originated from a certified forest

Chain of Custody
•There are two types of certifications:
Forest Management
Chain of Custody
Primary Manufacturing of materials
Pulp to paper
Secondary Manufacturing of materials
Paper to finished goods
Final delivery to end-user

Proper FSC Label Use
Two different uses of the label On-Product Labeling
When using On-Product label you must print on FSC-
certified paper bought from an FSC-certified merchant
Off-Product Labeling
Used for promotional use

The Rainforest Alliance works to conserve biodiversity and ensure
sustainable livelihoods by transforming land-use practices, business
practices and consumer behavior.
We believe that the best way to keep forests standing is by
ensuring that it is profitable for businesses and communities to do
so. That means helping farmers, forest managers and tourism
businesses realize greater economic benefits by ensuring
ecosystems within and around their operations are protected, and
that their workers are well-trained and enjoy safe conditions,
proper sanitation, health care and housing. Once businesses meet
certain environmental and social standards, we link them up to the
global marketplace where demand for sustainable goods and services
is on the rise.

The Rainforest Alliance Family of Marks
Those businesses that meet the standards for their field earn access
to the Rainforest Alliance family of marks, which distinguish their
products and services in the marketplace. These marks make it easy
for consumers to identify a legitimately sustainable product or
service and support those businesses that are acting responsibly.
•Farms that meet the comprehensive criteria of the Sustainable
Agriculture Network earn the right to use the Rainforest Alliance
Certified seal.
•Forestry businesses that comply with the rigorous standards of the
Forest Stewardship Council (FSC) may use the Rainforest Alliance
Certified™ seal in conjunction with the FSC logo.
•Tourism companies that demonstrate progress toward minimizing
their environmental footprint and supporting their workers, local
cultures and surrounding communities receive the Rainforest Alliance
Verified mark.

Agriculture
Rainforest Alliance Certification
offers farms a way to distinguish
their products as being socially,
economically and environmentally
sustainable.
Forestry
Our diverse set of certification and
verification services includes
forest certification; legality,
logging and forest carbon
verification and validation; and
forest products chain-of-custody
certification (wood, paper,
furniture and more).

• We offer verification services to hotels, restaurants and inbo
tour operators who are interested in improving their

➢But it's not easy to trap this energy and convert it into electricity in large amounts. Thus, wave
power stations are rare
❖At a wave power station –
➢the incoming waves cause the water in the chamber to rise and fall, which
means that air is forced in and out of the hole in the top of the chamber.

Methods of Solid Waste Management
Sanitary Landfill:
Incineration:
Composting:
Recovery and Recycling:
Pyrolysis:

Effects of Poor Solid Waste Management
 Due to improper waste disposal systems particularly by municipal waste management teams, wastes
heap up and become a problem
 Dumping of waste materials forces biodegradable materials to rot and decompose under improper,
unhygienic and uncontrolled conditions.After a few days of decomposition, a foul smell is produced
and it becomes a breeding ground for different types of disease
 Solid wastes from industries are a source of toxic metals, hazardous wastes, and chemicals. When
released to the environment, the solid wastes can cause biological and physicochemical problems to the
environment and may affect or alter the productivity of the soils in that particular area.
 Toxic materials and chemicals may seep into the soil and pollute the ground water.
 When hazardous wastes like pesticides, batteries containing lead, mercury or zinc, cleaning solvents,
radioactive materials,e-waste and plastics are mixed up with paper and other scraps are burned they
produce dioxins and gasses.

Zero Waste Concept
Zero Waste Concept is a philosophy that encourages the redesign of resource life cycles so that all products
are reused and no wastes will be produced. The process recommended is one similar to the way that resources
are reused in nature.
Zero Waste concept requires :-
 designing and managing products and processes to systematically avoid and eliminate the volume and
toxicity of waste and materials,
 conserving and recovering all resources,
 investment in community waste reduction and recovery systems
 Public participation in recycling.
 Eliminate all discharges to land, water or air that are a threat to planetary, human, animal or plant health.
 Adopting 3R concepts ( reduce, reuse, recycle)
 Acquiring waste to energy technologies.

Indicators of Sustainable Design
MODULE 7

Outline
1. What are indicators of sustainable development?
2. Why are indicators of sustainable development useful
for measuring climate change impacts and responses?
3. Which indicators are used by countries?
4. Where are the main challenges for developing climate
change indicators of sustainable development?

Sustainable Development
• “Sustainable development is development that meets the needs of the present without
compromising the ability of future generations to meet their own needs.” (Brundtland
Commission)
• Sustainable development integrates economic development, social development and
environmental protection.
• Sustainable development has three overarching objectives and essential requirements:
• Poverty reduction;
• Changing unsustainable patterns of production and consumption;
• Protecting and managing the natural resource base of economic and social development.

Indicators of Sustainable Development
• Indicators of sustainable development can have multiple functions:
• Simplifying, clarifying and making aggregated information and scientific knowledge
available to policy-makers
• Measuring progress towards sustainable development goals
• Identifying critical issues for sustainable development
• Communicating the concept of sustainable development to policy-makers and the public

• Indicators of sustainable development often integrate economic, social and
environmental statistics, e.g.
• Resource efficiency indicators integrate economic and environmental statistics;
• Gender employment indicators integrate economic and social statistics;
• Air pollution indicator integrate social and environmental statistics;
• Indicator on sustainable resource management integrate all three dimensions, but are
often not fully developed.

• Indicators of sustainable development can use different frameworks.
• Frameworks determine what to measure and why
• Policy-oriented frameworks
• Guaranteed policy relevance, flexible, buy-in form stakeholders
• Prone to change with change in government, sometimes theoreticallyweak
• Theory-based frameworks
• More stable across time, more commonalities across countries, less subject to political change
• Other frameworks: Indices (theory-based or theory-free), Pressure-state-response
frameworks

• Many countries across the world utilize indicators of sustainable development, especially for
• Monitoring progress of their national sustainable development strategies;
• Assessing state of sustainable development.

• Provision of high-quality data (data collection and integration)
• Common types and sources of data needed
• National accounts
• Censuses
• Household and other surveys
• Administrative records
• Estimations based on agreed standards;
• Provision of statistical methodologies and standards;
• In some countries, official statistics have a lead role in analyzing and reporting of indicators

Benefits of indicators of sustainable development
for climate change
• Climate change is a sustainable development issue, not just an environmental
concern
• Climate change threatens to erase progress made in achieving sustainable development
goals
• Greenhouse gas emissions depend on economic and technological pathways.
• Current emissions impact on the living conditions of future generations.
• Poor and vulnerable countries are expected to face the greatest burden of climate
change, while having contributed the least to the problem.
 Indicators of sustainable development can be informative for climate change.

Benefits of indicators of sustainable development
for climate change
• Existing sustainable development indicator sets are a useful point of departure for the
derivation of climate change indicators.
• Recognizes the important linkages between climate change and other sustainable
development issues, e.g.
• Reducing emissions from combustion of (imported) fossil fuels can increase energy
security.
• Improved disaster risk management helps to address not only climate related events
(droughts, floods,…), but also non-climate related ones (earthquakes, volcanoes)
• Preserving forests to maintain natural capital and to sustain livelihoods also increases
carbon absorption.

Main challenges
• Defining the scope of climate change indicators of sustainable development
• Additional specific climate change indicators may be useful
• E.g. climate indicators, CO2 intensity of fuels, CO2 emissions from policy relevant sources such as cars
• Definitions of climate change adaptation are often vague.
• People and economies adapt to a multiple factors, climate change being one of them.
• If “development is the best form of adaptation”, are all development indicators climate change related?

What is “sustainability” according to the Partnership for
Sustainable Communities?
A Sustainable Community is “an urban, suburban or rural community that has more
housing and transportation choices, is closer to jobs, shops or schools, is more energy
independent, and helps protect clean air and water.”

Operationalizing Sustainable Communities: the Livability
Principles
1. Provide More Transportation Choices
2. Promote Equitable, Affordable Housing
3. Support Existing Communities

Example Indicators by LP*
Livability Principle and Theme Example Indicator Soc Econ Env
1. Provide more transportation choices
Commute mode/mode share
Percentage of miles traveled (or trips taken) by
sustainable modes (walking, biking, public
transportation) as a fraction of miles traveled by
private auto

Indicator Systems
Bundling together indicators to make it easier
for policymakers to comprehend and use them

Indices
 Mathematically aggregate two or more indicators into
a single summary indicator
 Problem: Few if any indices currently in use fulfill
fundamental scientific requirements, limiting their
usefulness in policymaking*
