Author:Scholes, RJ; Van der Merwe, Martina RDate:May 1996South African greenhouse gas emissions contributed about 1.2% to the global increase in the greenhouse effect in 1988. South Africa generated trace gases with a radiation absorption potential over a 20-year period equivalent to 534 million ...Read more
Author:Jagarnath, M; Thambiran, TirushaDate:Aug 2017Because current emissions accounting approaches focus on an entire city, cities are often considered to be large emitters of greenhouse gas (GHG) emissions, with no attention to the variation within them. This makes it more difficult to ...Read more
