“…LCA is becoming more widely acknowledged as a cutting-edge methodology to sustainability in the construction sector. LCA is a methodology used to assess resource use, energy use, waste generation, and many other global environmental impacts throughout a project's lifespan [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. The LCA method helps to better visualize and provide answers to questions like what kind of material or constructive process can make a building more sustainable?…”

A literature survey was proposed, aiming at summarizing the state of the art and, consequently, the research potential, in the increasingly popular field of circular economy, specifically applied to the construction industry in South Asian countries (Pakistan, India, and Bangladesh). In particular, the role of a life cycle assessment (LCA) to support the circular building design concept in construction projects was investigated. This review organized 71 published papers that examined environmental building assessments, certifications for sustainable buildings, the awareness of sustainable buildings, and recent advancements in this field between 2005 and 2022. The review pointed out that half of the LCA studies used the cradle-to-grave LCA methodology for environmental impact assessment, while the other half used the cradle-to-cradle LCA methodology. Regardless of the recent research, the literature still lacks the cradle-to-cradle implementation of the LCA methodology in selected countries which is essential for implementing truly circular building strategies. Moreover, the literature showed a lack of interest and awareness among all stakeholders in the construction of environmentally friendly buildings. The main barrier to carry out LCA for building performance is the unavailability of a regional database, which was pointed out in the literature, as well as the criteria for certification that are not available or do not comply with the standards of the specific contexts of Pakistan, India, and Bangladesh.

Using the Life Cycle Assessment (LCA) approach, environmental benefits in terms of CO2 stored in chestnut wood in Italy have been calculated. Using one of the methodologies proposed under the LCA umbrella, a physical and formal balance sheet of CO2 has been built. Chestnut forests (Castanea sativa Mill.) are one of the most critical forest types in Europe. They cover an area of 800,000 hectares in Italy, most of which are managed as coppices. Chestnut wood’s high-quality physical-chemical and mechanical characteristics and medium-long durability explains its widespread uses. In this case study a section of a public forest in Central Italy (Lazio Region) has been considered. In the section, during the rotation, two types of intervention were carried out: thinning at 19 years of age, and final cutting at the age of 32. A production of 416 and 93 m3ha−1 for final cutting and thinning, respectively, was recorded. The global amount of 507 m3 is the functional unit, which has stored 547,875 kgCO2. The combination of forest management and sawmill processing produces semi-finished chestnut timber products for 125 m3, which have a physical storage of 135,210 kgCO2. Using the formal balance sheet of CO2, total emissions from processing were recorded for a total of 27,766 kgCO2. At the exit of sawmill, products stored 107,444 kgCO2, which is the amount of Net-Carbon Dioxide Surplus (Net-CDS). Transportation from sawmill to market reduces the sequestered CO2 by 0.77 kgCO2/km. The Net-CDS represents a competitive advantage in the timber market. If tree species have the same physical, chemical, mechanical and price parameters, the timber consumer would prefer to buy wood with the highest Net-CDS.
