Bangladesh is one of the most vulnerable nations in the world due to climate change. As the ninth most populous country and twelfth most densely populated countries in the world, its rising population and limited land space have put tremendous strains on the urban ecosystem. The capital of Dhaka itself underwent severe transformations in recent years to catch up the increased rate of urbanisation. This change was paralleled by a boom in the real estate, construction and housing industry. According to United Nations Population Fund (UNFPA), Dhaka is one of the most polluted cities in the world.[1]
Unified measures have been adopted from the national community in an effort to avoid further man made calamities due to climate change and higher emissions. There are six main sectors most likely to be affected by climate change in Bangladesh – water resources and coastal zones, infrastructure and human settlements, agriculture and food security, forestry and biodiversity, fisheries, and human health.[2]Deforestation has resulted in several man made disasters in the country's history. Green buildings assure efficient usage of water and energy and the nation is struggling in the production of electricity and suffering from a shortage of water.
The First Government Green Building Initiative was taken by the Housing and Building Research Institute in 2007[3]The Eco-Housing Project designed by Ar. Md Nafizur Rahman. With the support of IFC-world bank the HBRI Drafted the Guideline for Grenbuilding Code in 2012, in the same year a new chapter on Energy Efficiency and Sustainability was included in BNBC. The Building Energy and Environment Rating System for Bangladesh has been Drafted by Ar. Md. Nafizur Rahman[4] in 2018 for the Sustainable and Renewable Energy Authority (SREDA) The Bangladesh Bank[5] with te support of SREDA also created a point-based rating system for their Refinancing scheme in 2017. In the private sector, the first green building in Bangladesh was by EPIC group in May 2011.[6] Since 2008, Sustainable Built Environment Initiative – Bangladesh (later Bangladesh Green Building Council) founder, Sanwar Azam had worked to unify the stake holders towards a greener country, saying that with growing population in a diminishing land and rapid urbanisation to major cities, 'Going green' had become a marketing ploy for various organisations as there were no quantifiable way to judge a structures sustainability.[7] He offered a centralised board to offer Leadership in Energy and Environmental Design (LEED) certifications to interested projects and firms.[8] In addition, he proposed a similar voluntary building rating tool that is much cheaper to attain and one that is much suited to the socio-economic conditions of the country and relevant to its building environment and construction culture.[9]
In an event with Architecture and construction experts, he urged for a national need for sustainable development in the nation's growing building industry and brought a forum together to act as the national GBC of Bangladesh. He stressed reductions of carbon emissions from buildings. National and international energy companies like Energpac and Siemens attended the event to assess the roles of the corporate stakeholders while United Nations Framework Convention on Climate Change (UNFCCC) and Intergovernmental Panel on Climate Change (IPCC) fellows commented on the global imperative of such an initiative.[11] The first proposed rating tool aimed to fulfill the seventh target from the United Nations' Millennium Development Goals (MDGs), as for the first time the council provided support for green building certifications.[12] Initially with minimal government support, the plan was to transform the market with cost effective steps. In another interview with The Independent, Sanwar said "there is a great misconception regarding the cost effectiveness of the green design and construction," and that increased productivity and energy savings of a green building outweighs initial costs. About the feasibility of widespread utilisation of LEED certifications, he said that it is very expensive and the Bangladesh is in the process of developing a green building rating system in the regional context.[13] These activities were also promoted by national and region experts. Prominent national award-winning architects such as Mustapha Khalid Palash, the 2010 Holcim Green Built Sustainable Design Competition winner was the Chairman of the Practicing Professionals Committee, and Rafiq Azam, defined BGBC platform as a way for Bangladesh to define 'Green' according to the national circumstances.[14] The Institute of Architects Bangladesh, which works with different government organisation to offer education and government advocacy commented on the adaptability of sustainable principles in the national architecture community in the form of the BGBC rating tool.[15]
In 2011, BGBC founder pointed out that such green building standards and tools will lead to conservation as buildings would less consumption of electricity and water,[8] and also 'the need for reduction of carbon emissions' in the current building and construction scenario. At the same meeting, the Additional Chief Architect of the Ministry of Housing and Public Works, Bangladesh spoke about the government's role.[11] By 2012, the Ministry of Public Works began working with the World Bank[16] to study energy and water efficiency[17] and emissions reductions through Green Building Codes.[18]

The United Nations Environment Programme (UNEP) is responsible for coordinating responses to environmental issues within the United Nations system. It was established by Maurice Strong, its first director, after the United Nations Conference on the Human Environment in Stockholm in June 1972. Its mandate is to provide leadership, deliver science and develop solutions on a wide range of issues, including climate change, the management of marine and terrestrial ecosystems, and green economic development. The organization also develops international environmental agreements; publishes and promotes environmental science and helps national governments achieve environmental targets.
Environmental finance is a field within finance that employs market-based environmental policy instruments to improve the ecological impact of investment strategies. The primary objective of environmental finance is to regress the negative impacts of climate change through pricing and trading schemes. The field of environmental finance was established in response to the poor management of economic crises by government bodies globally. Environmental finance aims to reallocate a businesses resources to improve the sustainability of investments whilst also retaining profit margins.
A green economy is an economy that aims at reducing environmental risks and ecological scarcities, and that aims for sustainable development without degrading the environment. It is closely related with ecological economics, but has a more politically applied focus. The 2011 UNEP Green Economy Report argues "that to be green, an economy must not only be efficient, but also fair. Fairness implies recognizing global and country level equity dimensions, particularly in assuring a Just Transition to an economy that is low-carbon, resource efficient, and socially inclusive."
Green building refers to both a structure and the application of processes that are environmentally responsible and resource-efficient throughout a building's life-cycle: from planning to design, construction, operation, maintenance, renovation, and demolition. This requires close cooperation of the contractor, the architects, the engineers, and the client at all project stages. The Green Building practice expands and complements the classical building design concerns of economy, utility, durability, and comfort. Green building also refers to saving resources to the maximum extent, including energy saving, land saving, water saving, material saving, etc., during the whole life cycle of the building, protecting the environment and reducing pollution, providing people with healthy, comfortable and efficient use of space, and being in harmony with nature. Buildings that live in harmony; green building technology focuses on low consumption, high efficiency, economy, environmental protection, integration and optimization.’
Green development is a real estate development concept that considers social and environmental impacts of development. It is defined by three sub-categories: environmental responsiveness, resource efficiency, and community and cultural sensitivity. Environmental responsiveness respects the intrinsic value of nature, and minimizes damage to an ecosystem. Resource efficiency refers to the use of fewer resources to conserve energy and the environment. Community and cultural sensitivity recognizes the unique cultural values that each community hosts and considers them in real estate development, unlike more discernable signs of sustainability, like solar energy,. Green development manifests itself in various forms, however it is generally based on solution multipliers: features of a project that provide additional benefits, which ultimately reduce the projects' environmental impacts.
Leadership in Energy and Environmental Design (LEED) is a green building certification program used worldwide. Developed by the non-profit U.S. Green Building Council (USGBC), it includes a set of rating systems for the design, construction, operation, and maintenance of green buildings, homes, and neighborhoods, which aims to help building owners and operators be environmentally responsible and use resources efficiently.
EcoHomes was an environmental rating scheme for homes in the United Kingdom. It was the domestic version of the Building Research Establishment's Environmental Assessment Method BREEAM, which could also be applied to a variety of non-residential buildings. It was replaced by the Code for Sustainable Homes in April 2008.
The Code for Sustainable Homes was an environmental assessment method for rating and certifying the performance of new homes in United Kingdom. First introduced in 2006, it is a national standard for use in the design and construction of new homes with a view to encouraging continuous improvement in sustainable home building. In 2015 the Government in England withdrew it, consolidating some standards into Building Regulations.
This article provides examples of green building programs in the United States. These programs span the public, private, and non-profit sectors, and all have the goal of increasing energy efficiency and the sustainability of the built environment.
Green growth is a concept in economic theory and policymaking used to describe paths of economic growth that are environmentally sustainable. It is based on the understanding that as long as economic growth remains a predominant goal, a decoupling of economic growth from resource use and adverse environmental impacts is required. As such, green growth is closely related to the concepts of green economy and low-carbon or sustainable development. A main driver for green growth is the transition towards sustainable energy systems. Advocates of green growth policies argue that well-implemented green policies can create opportunities for employment in sectors such as renewable energy, green agriculture, or sustainable forestry.
Green building on college campuses is the purposeful construction of buildings on college campuses that decreases resource usage in both the building process and also the future use of the building. The goal is to reduce CO2 emissions, energy use, and water use, while creating an atmosphere where students can be healthy and learn.

A green home is a type of house designed to be environmentally sustainable. Green homes focus on the efficient use of "energy, water, and building materials". A green home may use sustainably sourced, environmentally friendly, and/or recycled building materials. This includes materials like reclaimed wood, recycled metal, and low VOC paints. Additionally, green homes often prioritize energy efficiency by incorporating features, such as high-performance insulation, energy-efficient appliances, and smart home technologies that monitor and optimize energy usage. Water conservation is another important aspect, with green homes often featuring water-saving fixtures, rainwater harvesting systems, and grey water recycling systems to reduce water waste. It may include sustainable energy sources such as solar or geothermal, and be sited to take maximum advantage of natural features such as sunlight and tree cover to improve energy efficiency.
Sustainable products are products either sustainably sourced, manufactured or processed and provide environmental, social, and economic benefits while protecting public health and the environment throughout their whole life cycle, from the extraction of raw materials to the final disposal.
"Sustainability," was defined as “development which implies meeting the needs of the present without compromising the ability of future generations to meet their own needs”as defined by the 1983 Brundtland Commission. As sustainability gains support and momentum worldwide, universities across the United States have expanded initiatives towards more sustainable campuses, commitments, academic offerings, and student engagement.
Sustainable urbanism is both the study of cities and the practices to build them (urbanism), that focuses on promoting their long term viability by reducing consumption, waste and harmful impacts on people and place while enhancing the overall well-being of both people and place. Well-being includes the physical, ecological, economic, social, health and equity factors, among others, that comprise cities and their populations. In the context of contemporary urbanism, the term cities refers to several scales of human settlements from towns to cities, metropolises and mega-city regions that includes their peripheries / suburbs / exurbs. Sustainability is a key component to professional practice in urban planning and urban design along with its related disciplines landscape architecture, architecture, and civil and environmental engineering. Green urbanism and ecological urbanism are other common terms that are similar to sustainable urbanism, however they can be construed as focusing more on the natural environment and ecosystems and less on economic and social aspects. Also related to sustainable urbanism are the practices of land development called Sustainable development, which is the process of physically constructing sustainable buildings, as well as the practices of urban planning called smart growth or growth management, which denote the processes of planning, designing, and building urban settlements that are more sustainable than if they were not planned according to sustainability criteria and principles.
Climate change is a critical issue in Bangladesh. as the country is one of the most vulnerable to the effects of climate change. In the 2020 edition of Germanwatch's Climate Risk Index, it ranked seventh in the list of countries most affected by climate calamities during the period 1999–2018. Bangladesh's vulnerability to the effects of climate change is due to a combination of geographical factors, such as its flat, low-lying, and delta-exposed topography. and socio-economic factors, including its high population density, levels of poverty, and dependence on agriculture. The impacts and potential threats include sea level rise, temperature rise, food crisis, droughts, floods, and cyclones.
Climate finance is an umbrella term for financial resources such as loans, grants, or domestic budget allocations for climate change mitigation, adaptation or resiliency. Finance can come from private and public sources. It can be channeled by various intermediaries such as multilateral development banks or other development agencies. Those agencies are particularly important for the transfer of public resources from developed to developing countries in light of UN Climate Convention obligations that developed countries have.

Green building certification systems are a set of rating systems and tools that are used to assess a building or a construction project's performance from a sustainability and environmental perspective. Such ratings aim to improve the overall quality of buildings and infrastructures, integrate a life cycle approach in its design and construction, and promote the fulfillment of the United Nations Sustainable Development Goals by the construction industry. Buildings that have been assessed and are deemed to meet a certain level of performance and quality, receive a certificate proving this achievement.
