With the rapid urbanization, population growth and advancement of technologies, human impact on temperature rise is becoming a severe issue. Unprecedented burning of fossil fuels and deforestation escalate carbon dioxide concentration (CO2) and global warming causing many environmental impacts. Road traffic is identified as a major contributor to CO2 concentration. Integration of street greenery is recognized as the best strategy in addressing this scenario. However, in Sri Lankan context the importance of street greenery is less considered when implementing infrastructure development plans. And the true potentials of street greenery is not adequately researched to implement street greenery as a vital planning strategy. Thus, the research aims at investigating the benefit of street greenery to overcome CO2 concentration and pedestrian discomfort at street level in local context to highlight the importance of integrating street greenery as a vital urban planning strategy. The paper presents findings of the research conducted in the city of Kandy. Three main street sections of Kandy city were observed, investigated and measured. A clear variation in temperature and CO2 concentration was identified in Kandy city streets with greenery and less greenery. Pedestrian preference for streets with greenery too was highlighted though the results.
