Sustainable living


Sustainable living describes a lifestyle that attempts to reduce the use of Earth's natural resources by an individual or society. Its practitioners often attempt to reduce their ecological footprint by altering their home designs and methods of transportation, energy consumption and diet. Its proponents aim to conduct their lives in ways that are consistent with sustainability, naturally balanced, and respectful of humanity's symbiotic relationship with the Earth's natural ecology. The practice and general philosophy of ecological living closely follows the overall principles of sustainable development.
One approach to sustainable living, exemplified by small-scale urban transition towns and rural ecovillages, seeks to create self-reliant communities based on principles of simple living, which maximize self-sufficiency, particularly in food production. These principles, on a broader scale, underpin the concept of a bioregional economy.

Definition

Sustainable living is fundamentally the application of sustainability to lifestyle choices and decisions. One conception of sustainable living expresses what it means in triple-bottom-line terms as meeting present ecological, societal, and economical needs without compromising these factors for future generations. Another broader conception describes sustainable living in terms of four interconnected social domains: economics, ecology, politics, and culture. In the first conception, sustainable living can be described as living within the innate carrying capacities defined by these factors. In the second or Circles of Sustainability conception, sustainable living can be described as negotiating the relationships of needs within limits across all the interconnected domains of social life, including consequences for future human generations and non-human species.
Sustainable design and sustainable development are critical factors to sustainable living. Sustainable design encompasses the development of appropriate technology, which is a staple of sustainable living practices. Sustainable development in turn is the use of these technologies in infrastructure. Sustainable architecture and agriculture are the most common examples of this practice.
Lester R. Brown, a prominent environmentalist and founder of the Worldwatch Institute and Earth Policy Institute, describes sustainable living in the twenty-first century as "shifting to a renewable energy-based, reuse/recycle economy with a diversified transport system." Anitra Nelson notes that the Degrowth movement has "pointed to ‘growth’ and ‘growth economies’ as the source of inequities and unsustainabilities" with the result that advocates call for "a radical reduction in production and consumption, greater citizen participation in politics, and more diversity, especially within ecological systems and landscapes, along with a flourishing of creativity, care, and commoning — using renewable energy and materials. Derrick Jensen, a celebrated American author, radical environmentalist and prominent critic of mainstream environmentalism argues that "industrial civilization is not and can never be sustainable". From this statement, the natural conclusion is that sustainable living is at odds with industrialization. Thus, practitioners of the philosophy potentially face the challenge of living in an industrial society and adapting alternative norms, technologies, or practices.

History

  • 1954 The publication of Living the Good Life by Helen and Scott Nearing marked the beginning of the modern day sustainable living movement. The publication paved the way for the "back-to-the-land movement" in the late 1960s and early 1970s.
  • 1962 The publication of Silent Spring by Rachel Carson marked another major milestone for the sustainability movement.
  • 1972 Donella Meadows wrote the international bestseller The Limits to Growth, which reported on a study of long-term global trends in population, economics and the environment. It sold millions of copies and was translated into 28 languages.
  • 1973 E. F. Schumacher published a collection of essays on shifting towards sustainable living through the appropriate use of technology in his book Small Is Beautiful.
  • 1992–2002 The United Nations held a series of conferences, which focused on increasing sustainability within societies to conserve the Earth's natural resources. The Earth Summit conferences were held in 1992, 1972 and 2002.
  • 2007 the United Nations published Sustainable Consumption and Production, Promoting Climate-Friendly Household Consumption Patterns, which promoted sustainable lifestyles in communities and homes.

    Shelter

On a global scale, shelter is associated with about 25% of the greenhouse gas emissions embodied in household purchases and 26% of households' land use.
Sustainable homes are built using sustainable methods, materials, and facilitate green practices, enabling a more sustainable lifestyle. Their construction and maintenance have neutral impacts on the Earth. Often, if necessary, they are close in proximity to essential services such as grocery stores, schools, daycares, work, or public transit making it possible to commit to sustainable transportation choices. Sometimes, they are off-the-grid homes that do not require any public energy, water, or sewer service.
If not off-the-grid, sustainable homes may be linked to a grid supplied by a power plant that is using sustainable power sources, buying power as is normal convention. Additionally, sustainable homes may be connected to a grid, but generate their own electricity through renewable means and sell any excess to a utility. There are two common methods to approaching this option: net metering and double metering.
Net metering uses the common meter that is installed in most homes, running forward when power is used from the grid, and running backward when power is put into the grid. Power companies can quickly purchase the power that is put back into the grid, as it is being produced. Double metering involves installing two meters: one measuring electricity consumed, the other measuring electricity created. Additionally, or in place of selling their renewable energy, sustainable home owners may choose to bank their excess energy by using it to charge batteries. This gives them the option to use the power later during less favorable power-generating times, and to be completely independent of the electrical grid.
Sustainably designed houses are generally sited so as to create as little of a negative impact on the surrounding ecosystem as possible, oriented to the sun so that it creates the best possible microclimate, and provide natural shading or wind barriers where and when needed, among many other considerations. The design of a sustainable shelter affords the options it has later Sustainably constructed houses involve environmentally friendly management of waste building materials such as recycling and composting, use non-toxic and renewable, recycled, reclaimed, or low-impact production materials that have been created and treated in a sustainable fashion, use as much locally available materials and tools as possible so as to reduce the need for transportation, and use low-impact production methods.
In April 2019, New York City passed a bill to cut greenhouse gas emissions. The bill's goal was to minimize the climate pollution stemming from the hub that is New York City. It was approved in a 42 to 5 vote, showing a strong favor of the bill. The bill will restrict energy use in larger buildings. The bill imposes greenhouse gas caps on buildings that are over 25,000 square feet. The calculation of the exact cap is done by square feet per building. A similar emission cap had existed already for buildings of 50,000 square feet or more. This bill expands the legislation to cover more large buildings. The bill protects rent-regulated buildings of which there are around 990,000. Due to the implementation of the bill, around 23,000 new green jobs will be created. The bill received support from Mayor Bill de Blasio. New York is taking action based on the recognition that their climate pollution has effects far beyond the city limits of New York. In discussion of a possible new Amazon headquarters in NYC, De Blasio specified that the bill applies to everyone, regardless of prestige. Mayor de Blasio also announced a lawsuit by the city to five major oil companies due to their harm on the environment and climate pollution. This also raises the question of the possible closing of the 24 oil and gas burning power plants in New York City, due to the aimed declining use of these sources of energy. With the emission cap, New York will likely see a turn to renewable energy sources. It is possible that these plants will be transitioned to hubs of renewable energy to power the city. This new bill will go into action in three years and is estimated to cut climate pollution by 40% in eight years.
Many materials can be considered a "green" material until its background is revealed. Any material that has used toxic or carcinogenic chemicals in its treatment or manufacturing, has traveled extensively from its source or manufacturer, or has been cultivated or harvested in an unsustainable manner might not be considered green. In order for any material to be considered green, it must be resource efficient, not compromise indoor air quality or water conservation, and be energy efficient. Resource efficiency can be achieved by using as much recycled content, reusable or recyclable content, materials that employ recycled or recyclable packaging, locally available material, salvaged or remanufactured material, material that employs resource efficient manufacturing, and long-lasting material as possible.

Sustainable building materials

Some building materials might be considered "sustainable" by some definitions and under certain conditions. For example, wood might be thought of as sustainable if it is grown using sustainable forest management, processed using sustainable energy, delivered by sustainable transport, etc. Under different conditions, however, it might not be considered as sustainable. The following materials might be considered as sustainable under certain conditions, based on a Life-cycle assessment:
  • Adobe
  • Bamboo
  • Cellulose insulation
  • Clay
  • Cob
  • Composite wood
  • Compressed earth block
  • Cordwood
  • Cork
  • Hemp
  • Insulating concrete forms
  • Lime render
  • Linoleum
  • Lumber from Forest Stewardship Council approved sources
  • Natural rubber
  • Natural fiber
  • Organic cotton insulation
  • Papercrete
  • Rammed earth
  • Reclaimed stone
  • Reclaimed brick
  • Recycled metal
  • Recycled concrete
  • Recycled paper
  • Soy-based adhesive
  • Soy insulation
  • Straw bale
  • Structural insulated panel
  • Wood
Insulation of a sustainable home is important because of the energy it conserves throughout the life of the home. Well insulated walls and lofts using green materials are a must as it reduces or, in combination with a house that is well designed, eliminates the need for heating and cooling altogether. Installation of insulation varies according to the type of insulation being used. Typically, lofts are insulated by strips of insulating material laid between rafters. Walls with cavities are done in much the same manner. For walls that do not have cavities behind them, solid-wall insulation may be necessary which can decrease internal space and can be expensive to install. Energy-efficient windows are another important factor in insulation. Simply assuring that windows are well sealed greatly reduces energy loss in a home. Double or Triple glazed windows are the typical method to insulating windows, trapping gas or creating a vacuum between two or three panes of glass allowing heat to be trapped inside or out. Low-emissivity or Low-E glass is another option for window insulation. It is a coating on windowpanes of a thin, transparent layer of metal oxide and works by reflecting heat back to its source, keeping the interior warm during the winter and cool during the summer. Simply hanging heavy-backed curtains in front of windows may also help their insulation. "Superwindows," mentioned in Natural Capitalism: Creating the Next Industrial Revolution, became available in the 1980s and use a combination of many available technologies, including two to three transparent low-e coatings, multiple panes of glass, and a heavy gas filling. Although more expensive, they are said to be able to insulate four and a half times better than a typical double-glazed windows.
Equipping roofs with highly reflective material increases a roof's albedo and will help reduce the amount of heat it absorbs, hence, the amount of energy needed to cool the building it is on. Green roofs or "living roofs" are a popular choice for thermally insulating a building. They are also popular for their ability to catch storm-water runoff and, when in the broader picture of a community, reduce the heat island effect thereby reducing energy costs of the entire area. It is arguable that they are able to replace the physical "footprint" that the building creates, helping reduce the adverse environmental impacts of the building's presence.
Energy efficiency and water conservation are also major considerations in sustainable housing. If using appliances, computers, HVAC systems, electronics, or lighting the sustainable-minded often look for an Energy Star label, which is government-backed and holds stricter regulations in energy and water efficiency than is required by law. Ideally, a sustainable shelter should be able to completely run the appliances it uses using renewable energy and should strive to have a neutral impact on the Earth's water sources
Greywater, including water from washing machines, sinks, showers, and baths may be reused in landscape irrigation and toilets as a method of water conservation. Likewise, rainwater harvesting from storm-water runoff is also a sustainable method to conserve water use in a sustainable shelter. Sustainable Urban Drainage Systems replicate the natural systems that clean water in wildlife and implement them in a city's drainage system so as to minimize contaminated water and unnatural rates of runoff into the environment.
