IMPLEMENT REWILDING FOR CARBON SEQUESTRATIONHow can thoughtful landscape design enrich storm-water management (i.e. bioswales), beautification,and buffer pedestrians from car lanes along the pedestrian way?What plant and tree selections provide shade canopy and the best carbon sequestration over time?1. VegetationVegetation sequesters and stores carbon during its growth. It can enhance a city’s micro-climate,which has positive side-effects on residents and buildings.• Aim to increase and carve out dedicated green spaces planted with native and highsequestration tree species.• When possible, introduce networks of green streets and connect the layers of urban parks.• With repaving cycles, modify impervious surfaces to permeable pavements (i.e. recycled content+ turfgrass, etc.).• Utilize landscape as a means of creating the streetscape and sequestering water + retainingwater.• Utilize opportunities on-site for multi-functionality is critical. Linear roads and grading allow foreffective bioswales that serve multiple environmental benefits. Additionally, they can serve asstreetscape elements such as bike lane division and public nodes.• Occupy urban brownfields and temporal vacancies with low embodied carbon greeningstrategies in the meantime (e.g. retaining excavated soil on-site with low maintenanceswitchgrass growth).• Allow infrastructure to collect organic waste materials to redirect it towards compost or biocharinstead of incineration.2. SequestrationSequestration is the only removal method in which carbon from the atmosphere can be taken outinstead of avoided. There are three main types of sequestration:•••52Biological Carbon Sequestration: storage of carbon dioxide in vegetation, soils, and oceans.Through photosynthesis, vegetation fix atmospheric carbon dioxide into biomass and ultimatelyconvert into soil organic carbon (SOC) by forming organo-mineral complexes. Throughexchange with the atmosphere and other chemical processes, the ocean naturally stores carbondioxide as dissolved gas or carbonate sediments on the seafloor. It can also take up carbondioxide through photosynthesis by the phytoplankton that live within its waters.Geological Carbon Sequestration: carbon dioxide can be stored in underground geologicformations (rocks). There are facilities where carbon dioxide is injected into porous rocks forlong-term storage.Technological Carbon Sequestration: involve new ways to remove and store carbon from theatmosphere including innovations like direct air capture (DAC). With DAC, air filters capturecarbon dioxide directly from the atmosphere then concentrate and transport it for storage orconversion into useful products such as fuels and industrial chemicals. Other methods includebiochar, cryogenic carbon capture (CCC) for removing carbon dioxide from gas streams, theuse of nanomaterials, amine-based capture absorbing carbon dioxide before release intothe atmosphere, etc. There are many technologies currently in research, development, or inoperation.archimaniaTranssolarKlimaEngineering
