A call for electric car charging points at home

One of the many changes needed for Switzerland to eliminate greenhouse gas emissions is to make its road mobility electric, with sales on new internal combustion engine (ICE) vehicles to cease by 2030 or soon after. As numerous ...

Reducing embodied carbon in steel-framed buildings

Over the last ten years, global demand for concrete has grown three-fold and for steel two-fold. Both are responsible for approximately 15% of global greenhouse gas emissions (GHG), 75% of which is associated with buildings ...

Greenhouse gas

Greenhouse gases are gases in an atmosphere that absorb and emit radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. Common greenhouse gases in the Earth's atmosphere include water vapor, carbon dioxide, methane, nitrous oxide, and ozone. In our solar system, the atmospheres of Venus, Mars and Titan also contain gases that cause greenhouse effects. Greenhouse gases greatly affect the temperature of the Earth; without them, Earth's surface would be on average about 33°C (59°F) colder than at present.

Human activities since the start of the industrial era around 1750 have increased the levels of greenhouse gases in the atmosphere. The 2007 assessment report compiled by the IPCC observed that "changes in atmospheric concentrations of greenhouse gases and aerosols, land cover and solar radiation alter the energy balance of the climate system", and concluded that "increases in anthropogenic greenhouse gas concentrations is very likely to have caused most of the increases in global average temperatures since the mid-20th century".
