The anticipated growth and urbanization of the global population over the next several decades will create a vast demand for the construction of new housing, commercial buildings and accompanying infrastructure. The production of cement, steel and other building materials associated with this wave of construction will become a major source of greenhouse gas emissions. Might it be possible to transform this potential threat to the global climate system into a powerful means to mitigate climate… Expand

The Role of Urbanization in the Global Carbon Cycle
Urban areas account for more than 70% of CO2 emissions from burning fossil fuels. Urban expansion in tropics is responsible for 5% of the annual emissions from land use change. Here I show that theExpand
Carbon emissions of infrastructure development.
TLDR
The carbon footprint of the existing global infrastructure stock in 2008, assuming current technologies, is estimated to be 122 (-20/+15) Gt CO2, which corresponds to about 35-60% of the remaining carbon budget available until 2050 if the average temperature increase is to be limited to 2 °C, and could thus compromise the2 °C target.

TLDR
A carbon sequestration strategy is proposed in which certain dead or live trees are harvested via collection or selective cutting, then buried in trenches or stowed away in above-ground shelters, thus an attractive option for large-scale implementation in a world-wide carbon market. Expand

Abstract. The global production of cement has grown very rapidly in recent years, and after fossil fuels and land-use change, it is the third-largest source of anthropogenic emissions of carbonExpand
Net-zero emissions energy systems
TLDR
The special challenges associated with an energy system that does not add any CO2 to the atmosphere (a net-zero emissions energy system) are reviewed and prominent technological opportunities and barriers for eliminating and/or managing emissions related to the difficult-to-decarbonize services are discussed.
