What is ‘E’ in ESG? – How Organization Manages Its Impact on Environment

The ‘E’ in ESG stands for Environmental, representing the crucial pillar that examines how organizations interact with and impact the natural world. This component evaluates a company’s practices, policies, and performance related to environmental stewardship, including their carbon footprint, resource consumption, waste management, and overall ecological impact. As climate change accelerates and natural resources become increasingly scarce, the environmental dimension of ESG has evolved from a corporate social responsibility checkbox into a fundamental business imperative that influences operational efficiency, risk management, and long-term sustainability. In this article, we are dedicated to explaining what is ‘E’ in ESG in detail. 

‘E’ in ESG – A Brief Overview

The environmental component of ESG encompasses a comprehensive framework that assesses how businesses contribute to or mitigate environmental challenges facing our planet. It measures tangible metrics such as greenhouse gas emissions, energy efficiency, water usage, biodiversity protection, and pollution prevention. Beyond mere compliance with environmental regulations, this pillar encourages organizations to adopt proactive strategies that minimize ecological harm while creating value for stakeholders. Companies are increasingly recognizing that strong environmental performance correlates with operational excellence, innovation, and competitive advantage. From reducing energy costs through efficiency improvements to attracting environmentally conscious consumers and investors, the environmental factor has become integral to corporate strategy and valuation in the modern business landscape.

Environmental Factors That Organizations Must Consider

Organizations today face mounting pressure from regulators, investors, consumers, and communities to address their environmental impact comprehensively. The environmental dimension of ESG encompasses multiple interconnected factors that directly influence both ecological health and business performance. These factors range from climate-related risks and carbon emissions to resource depletion and ecosystem preservation. Understanding and effectively managing these environmental considerations has become essential for maintaining regulatory compliance, securing investment capital, preserving brand reputation, and ensuring long-term operational viability in an era of heightened environmental awareness.

Climate Change and Carbon Emissions

Climate change represents one of the most pressing environmental challenges of our time, driven primarily by greenhouse gas emissions from human activities. Organizations contribute to climate change through direct emissions from their operations (Scope 1), indirect emissions from purchased energy (Scope 2), and emissions throughout their value chain (Scope 3). The accumulation of carbon dioxide, methane, and other greenhouse gases in the atmosphere leads to rising global temperatures, extreme weather events, sea-level rise, and disrupted ecosystems. For businesses, climate change poses both physical risks—such as supply chain disruptions from extreme weather—and transition risks related to policy changes, technological shifts, and market dynamics as the world moves toward a low-carbon economy.

How Organizations Can Manage Climate Change and Carbon Emissions

• Measure the full carbon footprint across all three emission scopes and set science-based reduction targets aligned with the Paris Agreement.
• Improve energy efficiency, switch to renewable energy sources, and electrify vehicle fleets to cut direct emissions.
• Optimize supply chains by partnering with low-carbon suppliers and enhancing logistics to reduce transportation emissions.
• Invest in carbon offset projects like reforestation or renewable energy, ensuring they supplement— not replace— direct reduction efforts.
• Integrate climate strategies into business planning, assess climate risks, and disclose performance using frameworks like TCFD.

Energy Consumption and Efficiency

Energy consumption is a critical environmental factor as it directly links to greenhouse gas emissions, operational costs, and resource depletion. Most global energy still comes from fossil fuels, making energy-intensive operations significant contributors to environmental degradation. Organizations across industries—from manufacturing plants and data centers to office buildings and retail stores—consume vast amounts of energy for heating, cooling, lighting, production processes, and equipment operation. Inefficient energy use not only increases carbon emissions but also represents wasted financial resources and heightened vulnerability to energy price volatility. As energy demands continue rising globally, improving energy efficiency has become both an environmental necessity and a business opportunity.

How Organizations Can Manage Energy Consumption and Efficiency

• Conduct regular energy audits to identify inefficiencies and opportunities for optimization across operations.
• Upgrade to energy-efficient technologies such as LED lighting, smart management systems, and high-efficiency HVAC units.
• Use real-time energy monitoring to track usage, detect anomalies, and make data-driven efficiency improvements.
• Shift to renewable energy through on-site generation or power purchase agreements for a cleaner energy supply.
• Set clear energy performance targets, assign management roles, and engage employees to promote energy-saving behaviors.

Water Management and Conservation

Water is an increasingly scarce resource essential for countless industrial processes, agricultural activities, and human consumption. Organizations across sectors, from beverage companies and textile manufacturers to technology firms and hospitality businesses, depend heavily on water availability for their operations. Water stress, affecting over 2 billion people globally, is intensifying due to climate change, population growth, and pollution. Poor water management leads to ecosystem degradation, community conflicts, regulatory penalties, and operational disruptions. Beyond consumption, organizations must consider water pollution through discharge of chemicals, waste products, and heated water that can harm aquatic ecosystems and contaminate drinking water sources.

How Organizations Can Manage Water Management and Conservation

• Measure water use across operations with audits to identify high-consumption areas and opportunities for efficiency.
• Adopt water-saving technologies like low-flow fixtures, closed-loop systems, and water recycling infrastructure.
• Treat and reuse wastewater, implement rainwater harvesting, and explore waterless or dry production alternatives.
• Conduct water risk assessments to focus conservation efforts in water-stressed regions.
• Set science-based water targets, engage with local communities, and report transparently through frameworks like the CEO Water Mandate.

Waste Management and Circular Economy

The linear “take-make-dispose” economic model generates enormous waste volumes that overwhelm landfills, pollute ecosystems, and squander valuable resources. Organizations produce various waste streams including manufacturing scrap, packaging materials, electronic waste, food waste, and hazardous substances. This waste represents not only environmental harm but also economic inefficiency, materials purchased but not converted into value. The circular economy paradigm offers an alternative approach where products and materials are designed for durability, reuse, repair, remanufacturing, and recycling, keeping resources in use as long as possible. Adopting circular principles reduces environmental impact while creating new business opportunities through resource efficiency and innovative business models.

How Organizations Can Manage Waste Management and Circular Economy

• Conduct waste audits to analyze waste types and volumes, then set reduction targets following the waste hierarchy: reduce, reuse, recycle, recover, dispose.
• Design products for circularity using recyclable materials, modular components, and non-hazardous substances to minimize waste.
• Implement recycling, composting, and industrial symbiosis programs to maximize resource recovery and reduce landfill waste.
• Adopt circular business models like product take-back, remanufacturing, and product-as-a-service to extend product lifecycles.
• Collaborate with suppliers on sustainable packaging, phase out single-use plastics, and engage employees in waste reduction efforts.

Biodiversity and Ecosystem Protection

Biodiversity, the variety of life on Earth including species diversity, genetic diversity, and ecosystem diversity, is declining at an unprecedented rate due to habitat destruction, pollution, climate change, and overexploitation. Organizations impact biodiversity through land use changes, pollution, resource extraction, and supply chain activities that affect natural habitats and species. Healthy ecosystems provide essential services that businesses depend on, including pollination, water filtration, climate regulation, soil formation, and raw material provision. The loss of biodiversity threatens these ecosystem services, creating risks for agriculture, pharmaceuticals, tourism, and numerous other sectors. Beyond utilitarian value, biodiversity has intrinsic worth and moral significance that responsible organizations must respect.

How Organizations Can Manage Biodiversity and Ecosystem Protection

• Conduct biodiversity assessments to identify dependencies and impacts across operations, especially near sensitive or protected areas.
• Apply the mitigation hierarchy, avoid, minimize, restore, and offset, with a focus on preventing biodiversity loss at the source.
• Protect ecosystems by maintaining buffer zones, creating wildlife corridors, and restoring degraded habitats.
• Source raw materials responsibly to prevent deforestation and ecosystem damage, ensuring sustainable supply chains.
• Partner with conservation groups, set measurable biodiversity targets, and report progress through frameworks like TNFD.
