Climate change mitigation entails taking measures to decrease greenhouse gases in order to stop Earth from warming too rapidly. It might involve switching from fossil fuel use to renewable sources or cutting down on car and plane travel as a form of climate protection.

Reducing short-lived climate pollutants such as black carbon and tropospheric ozone could save millions of lives by improving air quality; however, mitigating climate change will have its costs.

Reducing Energy Use in Buildings

architects play an essential role in shaping building construction, impacting energy efficiency and environmental impacts significantly. Their designs may contribute to climate change mitigation by employing sustainable structures that are more eco-friendly.

Buildings account for an immense proportion of global carbon emissions. Their construction requires raw materials, heavy machinery and transportation costs; plus use of harmful substances and high energy demands add a considerable carbon footprint during operation.

architects can mitigate climate change impacts by selecting materials with lower embodied energies, such as recycled steel, bamboo, clay and eco-friendly insulation materials. Furthermore, architects can save energy through optimizing design and implementing efficiency measures, including bioclimatic architecture, natural ventilation and behavioral changes such as turning off lights or unplugging equipment – which may reduce operational energy use up to 50 per cent – also helping mitigate climate change by eliminating fossil fuel-based power generation needs.

Carbon Reuse

The carbon cycle includes both natural and man-made processes that store and release carbon, such as natural processes or human activities such as burning fossil fuels and land development that emit heat-trapping greenhouse gases such as greenhouse gases that trap heat. Human activities which emit such greenhouse gases (such as using fossil fuels and developing land) can help mitigate climate change by either decreasing their flow into Earth’s atmosphere or by improving “sinks” that capture carbon from air pollution.

Sustainable management and conservation of forests as well as other ecosystems can act as a carbon sink by reducing deforestation and degradation while providing multiple other benefits, such as biodiversity preservation and improved water cycles.

Captured CO2 can be utilized in many ways. From commercially marketable products and permanent geologic storage to enhanced oil recovery (EOR) or producing renewable fuels and chemicals – its many potential uses make up a comprehensive climate strategy and may help significantly reduce emissions on their own. Although CO2 utilization has yet to achieve significant commercial scale, its potential use still needs further investigation for maximum benefit.

Carbon Storage

Carbon storage is a method of combatting climate change by collecting CO2 at emissions sources, treating it and transporting it to long-term storage locations for safekeeping. Also referred to as carbon capture and storage (CCS).

One such alternative to carbon dioxide removal is to store CO2 underground geological formations such as saline aquifers, depleted oil and gas reservoirs or coal seams. This technique has become an increasingly popular alternative as it doesn’t involve changes to energy usage patterns.

Another method is storing carbon in peat or bog. Peat absorbs CO2 as it forms naturally from the atmosphere, and stores it for many years ahead. Unfortunately, not all nations or companies can take advantage of these storage methods. Carbon dioxide can also be stored in ocean waters; eventually turning into carbonate minerals before being buried beneath deep geological layers as carbonate minerals. However, this option poses risks: worsening ocean acidification that kills coral reefs while endangering edible sea life that forms part of our food supply.

Biological Carbon Sequestration

Carbon sequestration, or locking carbon out of the atmosphere to avoid global warming, has become an integral component of climate change research as an antidote; by reducing human-produced greenhouse gases like carbon dioxide in the air.

Biological carbon sequestration refers to natural features, like forests, oceans and swamps (wetlands and peatlands) that absorb and store carbon dioxide naturally. Restoring or improving these natural features has an immediate effect on climate change mitigation as well as providing essential watershed services and ecosystem services that can benefit people as well as wildlife alike.

Soil can also absorb carbon, but much of it has been depleted through human activities. Research in this area seeks ways to restore depleted soils while recycling atmospheric carbon into biofuels like switch grass, miscanthus, karnal grass or willow that can be grown on dedicated energy plantations and used to offset fossil fuel emissions while decreasing atmospheric levels of CO2 and other greenhouse gases.
