The anthropogenic greenhouse effect is considered to be the leading cause of climate change worldwide. The anthropogenic greenhouse effect is the addition of greenhouse gas emissions to the natural greenhouse effect caused by human activities. The natural greenhouse effect is the process of the earth warming from the absorption of thermal energy by the atmosphere. The anthropogenic greenhouse effect is causing climate change due to excess amounts of greenhouse gases being emitted into the atmosphere which allows for a greater amount of heat to be trapped in the atmosphere. Having too much heat trapped in the atmosphere is causing an increase in the average global temperature which is resulting in a change of climate patterns internationally. Climate change is causing monumental amounts of consequences for the Earth, currently, climate change is resulting in rising sea levels, warmer bodies of water, droughts, wildfires, heat waves, melting ice, a greater storm severity, and floods, all of these have a harsh impact on our environment. We need to halt the rate at which climate change is occurring if we want to one day achieve environmental sustainability. Environmental sustainability occurs when the demands of the environment are being met while the capacity it is at is maintained. Currently, there are many ways environmental sustainability is trying to be achieved, one is green building. Green building demonstrates environmentally responsible and resource efficient structural and application processes whilst assembling structures. Green building is wildly important because buildings produce up to 35% of greenhouse gases, the construction and demolition of buildings create 35% of all landfill waste and 70% of municipal water is used in and around buildings.

Use of sustainable and renewable resources, use of renewable energy sources, use of lower volatile compound paints and stains, creation of green roofs, installation of energy efficient windows and doors, addition of water purification/management systems and the use of natural light are just some practices that green building follows.

A few benefits of green building are the decreased energy cost, less water wasted, improved air quality, conservation of natural resources, protection of ecosystems and biodiversity, workers are generally happier and healthier and green buildings usually sell for more.

There are three main types of green building certification systems, those include LEED certification, Net zero and the Passive house. Leadership in Energy and Environmental Design (LEED) is a rating system created by the United States Green Building Council in order to determine the environmental performance of a building. LEED assess multiple features of a building’s design and rates them based on whether the building is able to meet certain prerequisites and credits. LEED has quickly become one of the most favoured green building rating systems with over 80,000 projects participating in LEED worldwide.Team, G. (2017, March 21). 3 Types of Green Buildings You Should Know. Retrieved January 19, 2018, from https://www.green-buildings.com/articles/types-green-buildings-know/. Another green building rating system is Net-zero building, net-zero building is a building that produces the same amount of energy that it consumes. The majority of net-zero buildings get most of their energy from the grid and they return the same amount of energy. These buildings produce less greenhouse gas, but on some occasions, these buildings use non-renewable energy and they end up producing some greenhouse gas. Zero-energy building. (2018, January 19). Retrieved January 19, 2018, from https://en.wikipedia.org/wiki/Zero-energy_building. The Passive House Standard encourages airtight design by utilizing thermal performance and ventilation, which ultimately eliminates the need for heating and cooling systems. There are currently over 60,000 passive buildings worldwide. Passive house. (2018, January 18). Retrieved January 19, 2018, from https://en.wikipedia.org/wiki/Passive_house. I believe that LEED certification is the best choice when it comes to reducing our impact on climate change and promoting environmental sustainability. LEED is the best option because of how thoroughly it assess a buildings environmental impact, LEED looks at a structures planning, design, operations construction and demolition as well as water and energy usage, material selection, location and indoor environmental quality.

Since 2002 LEED has saved 6,503,647 eMWh, 12.8 billion litres of water, recycled over 1.6 million tonnes of construction and demolition waste, reduced 1,216,016 CO2e tonnes in greenhouse gas emissions, has created 231,608 square metres of green roofs.

By reducing 1,216,016 tonnes of greenhouse gas emissions LEED has helped to slow the rate at which climate change is occurring, LEED-certified buildings are reducing our anthropogenic greenhouse effect and are making our world a more environmentally sustainable place. Unlike the other types of green building techniques, LEED certification is the most simple, which means it can be more vastly spread. Climate change is a worldwide issue that will progressively get worse the longer we wait to take action and stop the anthropogenic greenhouse effect. Luckily plans to save our Earth from climate change are already being put into action, such as green building programs, this includes the LEED certification of buildings. If all buildings become LEED certified there would be a significant decline in the amount of greenhouse gases being released into the atmosphere, after that all we’d have to do to is become more environmentally sustainable in our day to day routines.
