Feasibility of Planting Trees around Buildings as a Nature-Based Solution of Carbon Sequestration—An LCA Approach Using Two Case Studies

In response to Canada’s commitment reducing greenhouse gas emissions and making pathways achieve carbon neutral buildings, this paper presents two real case studies. The first outlines the potential of trees absorb CO2 through photosynthesis, methods used for estimation their annual sequestration rates. net rate 0.575 kgCO2eq/m2 tree cover area is considered in our study. Then, life cycle assessment an all-electric laboratory at Concordia University a single-detached house, both located Montreal. (LCA) calculations were performed using software tools, One Click LCA Athena Impact Estimator Buildings. results terms Global Warming Potential (GWP) over 60 years found be 83,521 kgCO2eq LCA, 82,666 Athena. For house that uses natural space heating domestic hot water, GWP was 544,907 566,856 laboratory, garden fully covered with representative urban could offset around 17% total emissions. gas-powered by 3% emission. This limits achieving buildings when only applied, discusses main findings regarding under different scenarios.
