Embodied Carbon of Building Materials

The buildings where we live, work have a profound effect on our health. Embodied carbon of building materials includes the emissions due to energy consumption for resource extraction and material manufacture as well as the carbon emissions from transportation for building materials. 

Emission = Quantity of building material (e.g. m3) x carbon emission factor (kg CO2-e/m3)

Emission =  Weight of building material (e.g. kg) x the distance of transportation for material (km) x the carbon emission factor for transport means (kg CO2-e/tonne∙km)

New Balance says its sneakers will leave zero carbon footprint by 2050

 The World Bank says the fashion industry is responsible for about 10% of global emissions, leading some brands to take stock of their outsized carbon footprints.

New Balance Athletics operates three factories in Maine and has pledged to be net zero by 2050. The company's factories churn out thousands of sneakers every day.

An MIT lifecycle assessment estimates that producing just one pair of running shoes generates 30 pounds of carbon dioxide emissions. That's because it's an energy intensive process that uses cotton, leather and oil-dependent polyester. It also generates a lot of waste.

Emission factors for each mode of transport

 Emission factors for each mode of transport (e.g., aircraft, rail, metro, bus, taxi, bus), expressed in units of greenhouse gas (CO2, CH4, N2O, HFC, or CO2e) emitted per kilometer or per passenger-kilometer travelled.
