The ethics of transitioning to low Carbon, Sustainable Future in the Construction industry. ABSTRACT The global demand for sustainable materials is increasing, yet ethical sourcing remains a major challenge. Ethical sourcing ensures that materials are procured responsibly, with minimal harm to people and the environment. This paper explores key principles of ethical sourcing, the challenges faced by industries, and best practices for achieving transparency and accountability in material procurement.The study highlights sustainable materials, such as certified timber, recycled metals, and bio-based materials, while examining global certifications (e.g., FSC, Fair Trade, LEED) that regulate ethical sourcing. Challenges such as green washing, high costs, and supply chain complexity are also discussed. Finally, the paper provides solutions for improving supply chain transparency, stakeholder collaboration, and regulatory compliance.Findings suggest that companies that adopt ethical sourcing strategies not only reduce environmental impact but also enhance brand reputation, build stronger partnerships, and attract ESG-conscious investors.Keywords: Ethical sourcing, sustainable materials, supply chain transparency, ESG compliance, green procurement, circular economy INTRODUCTION The construction industry contributes positively to the Gross Domestic Product (GDP) of both developed and developing countries in addition to the industry`s capacity as a reliable employer. The relationship between the environment and construction industry can be said to be symbiotic since the industry relies heavy on the environment for inputs. According to Ugochukwu et al. (2015) construction inputs also determine the success of a project, where a shortfall affect both the quality and time of project completion. The construction industries heavily depend on raw materials, yet their sourcing methods often involve unethical practices such as illegal deforestation, exploitative labor, and excessive carbon emissions. Ethical sourcing of sustainable materials ensures that materials are obtained responsibly, with fair labour conditions, environmental conservation, and economic sustainability. The construction industry has started over exploitation of natural resources in order to meet the exponential demand.Developing countries face unique challenges, including weak institutions, rapid population growth, social injustice, political instability, and deficits in housing and infrastructure (Ofori, 1998; du Plessis, 2007). These issues hinder sustainability in the construction sector. Lehmann (2013) highlighted that construction significantly contributes to global greenhouse gas emissions, causing inefficiencies and high energy use. MIT (2013) warned that CO₂ levels, already at 478 ppm, are worsened by other greenhouse gases. Sev (2009) also noted that resource consumption in Sub-Saharan countries is unsustainable, requiring a pragmatic approach to manage limited resources.In addition, huge amount of Construction and Demolition waste (CD waste) being generated every year across the world is sent to land fill as dumps causing numerous environmental problems. The CD is waste generated during various construction activities such as site clearance, excavation, renovation, demolition, natural and man-made disasters, road construction. It includes different types of materials such as Earth, stone, sand, mixed soil during excavation, contaminated wood, bricks, tiles, concrete with or without reinforcing materials, insulation and roofing materials, salvaged building components, plumbing fixtures, asphalt during road repair and other waste materials. (Gupta et al.,2010)Unquestionably, the outcome of the Brundtland Report in 1987, the reports of the Rio de Janeiro and Johannesburg meeting as well as other recent efforts such as the Agenda 21 for sustainable construction have all contributed significantly to the global effort in achieving sustainable development. The most widely accepted view of sustainable development is that of the World Conference Environment and Development (1987), which views it as “Development that meets the needs of the present without compromising the ability of future generations to meet their own needs”With growing consumer awareness and global sustainability commitments (e.g., the Paris Agreement, UN Sustainable Development Goals), companies face increasing pressure to adopt transparent and ethical sourcing practices. However, challenges such as greenwashing, supply chain opacity, and regulatory inconsistencies continue to hinder progress. This paper explores:What ethical sourcing means and its importance in sustainability.Key challenges faced in ethical material procurement.Best practices in industries transitioning to responsible sourcing.Policy recommendations and technological solutions to enhance ethical sourcing. LITERATURE REVIEW Sustainable Construction Sustainable construction has gained significant attention in academia and industry as a response to ecosystem degradation and unequal resource use post-World War II (Dania et al., 2013). Bourdeau (1999) noted that calls for sustainability pushed the construction industry to adopt measures such as efficient energy use, waste reduction, and minimizing environmental impact (Pearce et al., 2012).This led to global initiatives, including Agenda 21 for Sustainable Construction (CIB, 1999). However, developing countries criticized its lack of inclusivity in the planning process (du Plessis, 2007; Ofori, 2007), prompting the creation of Agenda 21 for Sustainable Construction in Developing Countries (Dania et al., 2013). Despite this, progress remains limited due to political inertia and weak institutional frameworks. What is Ethical Sourcing? Raw materials are important to produce construction materials to meet ecological and socio-economic targets for the Sustainable Development Goals (Mancini & Nuss, 2020). Ethical sourcing covers issues relating to corporate social responsibility, sustainability reporting and ethical sourcing is a responsible supply chain approach that ensures: Fair labor conditions (no child labor, forced labor, or wage exploitation). Environmental conservation (sustainable forestry, low-carbon extraction, minimal waste). Legal and ESG compliance (adhering to industry regulations and ethical trade policies) According to Carter & Rogers (2008), ethical sourcing must balance profitability with corporate responsibility, ensuring that business operations do not exploit workers or harm ecosystems. The concept of ethical sourcing has only just begun to emerge as a reaction to the government`s approach on sustainability implementation in the construction industry.Ebohon and Rwelamila (2001) maintain that resources production pattern pollutes the rivers and other water bodies in addition to
