16.3 Carbon Footprint and Emissions Management

Carbon footprints and emissions management are crucial for businesses in today's eco-conscious world. Companies track their greenhouse gas emissions across three scopes: direct, indirect from energy, and value chain. This helps set reduction targets and measure environmental impact.

Strategies for reducing carbon footprints include offsetting, pricing mechanisms, and aiming for carbon neutrality. Companies also use science-based targets and climate risk assessments to align with global warming limits and prepare for climate-related challenges.

1 of 2

• Greenhouse gases (GHGs) trap heat in Earth's atmosphere, contributing to global warming
• Primary GHGs include carbon dioxide, methane, nitrous oxide, and fluorinated gases
• Carbon accounting measures and reports GHG emissions produced by organizations or activities
• Quantifies emissions in terms of carbon dioxide equivalents (CO2e)
• Enables companies to track their environmental impact and set reduction targets
• Involves collecting data on energy consumption, fuel use, and other emission-producing activities
• Utilizes standardized protocols (Greenhouse Gas Protocol) for consistent reporting across industries

Scope Classifications of Emissions

• Scope 1 emissions encompass direct GHG emissions from owned or controlled sources
  • Includes on-site fuel combustion (boilers, furnaces)
  • Company-owned vehicle emissions
  • Fugitive emissions from refrigerants or industrial processes
• Scope 2 emissions cover indirect GHG emissions from purchased electricity, steam, heating, and cooling
  • Represents emissions generated at power plants supplying energy to the organization
  • Varies based on the energy mix of the local grid (renewable vs. fossil fuel-based)
• Scope 3 emissions comprise all other indirect emissions in a company's value chain
  • Includes upstream activities (purchased goods and services, transportation of supplies)
  • Downstream activities (use of sold products, end-of-life treatment of products)
  • Employee commuting and business travel
  • Investments and leased assets

Carbon Reduction Strategies

Carbon Offsetting and Pricing Mechanisms

• Carbon offsetting involves investing in projects that reduce or remove GHG emissions
  • Reforestation initiatives
  • Renewable energy projects (wind farms, solar installations)
  • Methane capture from landfills or agricultural operations
• Carbon pricing assigns a monetary value to GHG emissions
  • Internalizes the environmental cost of carbon emissions
  • Encourages businesses to reduce emissions and invest in cleaner technologies
  • Can be implemented through carbon taxes or cap-and-trade systems
• Emissions trading schemes (ETS) create a market for buying and selling emission allowances
  • Cap-and-trade systems set an overall limit on emissions
  • Companies receive or purchase emission allowances
  • Can trade allowances with other companies based on their emission levels
  • Provides financial incentives for emission reductions

Achieving Carbon Neutrality

• Carbon neutrality refers to achieving net-zero carbon emissions
• Involves balancing carbon emissions with an equivalent amount of carbon removal or offsetting
• Strategies for achieving carbon neutrality include:
  • Improving energy efficiency in operations and buildings
  • Transitioning to renewable energy sources (solar, wind, hydroelectric)
  • Implementing sustainable transportation solutions (electric vehicles, optimized logistics)
  • Reducing waste and implementing circular economy principles
  • Investing in carbon capture and storage technologies
• Requires comprehensive emissions accounting and ongoing monitoring
• Many companies and organizations set target dates for achieving carbon neutrality

Climate Change Management

Science-Based Targets and Emission Reduction Goals

• Science-based targets align corporate emission reduction goals with climate science
• Based on the level of decarbonization required to keep global temperature increase below 2°C or 1.5°C
• Provides a clear pathway for companies to reduce their GHG emissions
• Involves setting both short-term and long-term emission reduction targets
• Requires regular progress monitoring and reporting
• Encourages innovation and drives sustainable business practices
• Enhances corporate reputation and stakeholder confidence

Climate Risk Assessment and Adaptation Strategies

• Climate risk assessment evaluates potential impacts of climate change on business operations
• Identifies physical risks (extreme weather events, sea-level rise) and transition risks (policy changes, market shifts)
• Helps organizations develop adaptation strategies to mitigate climate-related risks
• Involves scenario analysis to explore different climate futures and their potential impacts
• Informs strategic decision-making and long-term planning
• Adaptation strategies may include:
  • Diversifying supply chains to reduce vulnerability to climate-related disruptions
  • Investing in resilient infrastructure and facilities
  • Developing new products or services aligned with a low-carbon economy
  • Engaging with policymakers and stakeholders on climate-related issues
• Integrates climate considerations into overall risk management frameworks
