Document Summary
Involves human interventions to reduce greenhouse gas emissions and other environmental pollutants. Aims to slowing and ultimately halting the root causes of anthropogenic climate change. All energy sources come with some degree of a carbon footprint, even solar and wind. Carbon footprint of renewable energy resources is far less than fossil fuel sources. There has been emphasis on transitioning from fossil fuels to renewable energy to markedly decrease co2 emissions. Nuclear energy (non-renewable resource) has the lowest co2 footprint but comes at the cost of producing nuclear waste. The fabrication of cement (critical building material) requires mining of materials and produces a huge amount of carbon each year (major source of ghg) Efforts to offset this carbon and/or use renewable building materials like timber can reduce co2 footprint of infrastructure. Transportation can be made more efficient via 3 major vectors. Cleaner fuels, greener vehicles and smarter transportation infrastructure.
