The Glasgow School of Art (GSA) is comprised of a set of buildings placed next to each other on a valuable urban estate. Partly designed by the renowned architect, Charles Rennie Mackintosh, the campus accommodates a visual treat for tourists, yet it limits the provision of green amenity outdoor spaces. There is a dire need to soften its hard surface urban settings with healthy green landscaping and reduce the ambient carbon dioxide (CO2) levels with due consideration of global warming. This paper is aimed at examining the potential application of urban green schemes to the GSA campus so as to identify their ecological benefits. The impact of the plants on the micro-climate was examined through practical recordings and analysis of the similar urban settings in Glasgow. The results indicate that ambient CO2 levels can possibly be reduced by over 10% when urban vegetation schemes are applied properly to hard surface city structures. As well, this provides a description of the possible methods of incorporating greens, highlighting the various innovative options available today.
