Calculate and reduce Scope 2 GHG emissions

25 April 2024

Scope 2 GHG emissions arise from purchased electricity and require careful calculation for accurate ESG reporting. Implementing reduction strategies is essential for sustainability.

Understanding Scope 2 GHG Emissions

In the context of environmental responsibility, understanding the different scopes of greenhouse gas (GHG) emissions is crucial for corporations looking to calculate their ESG (Environmental, Social, and Governance) score. Scope 2 emissions refer to indirect GHG emissions from the consumption of purchased electricity, steam, heating, and cooling. Unlike direct emissions (Scope 1), which are produced on-site or by a company’s vehicles, Scope 2 emissions occur at the facility where the energy is generated.

Businesses looking to lower their carbon footprint need to accurately report and manage their Scope 2 emissions. This involves several steps, such as determining the boundaries of Scope 2 emissions, choosing the right method for calculating emissions, and developing strategies to reduce them. In-depth knowledge of Scope 2 is not just about compliance, but also about demonstrating to stakeholders a commitment to sustainability and environmental stewardship.

Calculating Your Company's Scope 2 Emissions

The process of calculating Scope 2 emissions can be complex, but it is essential for an accurate ESG score. It requires a comprehensive understanding of the energy procurement and the emissions factors associated with it. Two methodologies are widely used: the location-based method, which considers the average emissions intensity of grids on which energy consumption occurs, and the market-based method, which reflects the GHG emissions from the electricity that companies have purposefully chosen (or contracted).

Both methods have their merits, and it's critical for companies to disclose the method used when reporting their emissions. For instance, Sanofi’s environmental sustainability efforts showcase a transparent approach to managing their GHG emissions, including detailed Scope 2 emissions reporting. By examining such examples, businesses can better grasp how to accurately report and manage their own emissions.

Moreover, tools and guidelines provided by initiatives like the Greenhouse Gas Protocol and emission factors from databases such as the International Energy Agency (IEA) can help in the calculation process. Accurate tracking of electricity consumption data is also essential, which will require keeping good records and possibly investing in automated data collection systems.

Strategies for Reducing Scope 2 Emissions

Once a company has calculated its Scope 2 emissions, the next step is to develop and implement strategies for reduction. These can range from improving energy efficiency within operations to investing in renewable energy sources, either directly or through renewable energy certificates (RECs). Engaging suppliers and partners in sustainability efforts can also lead to significant reductions in Scope 2 emissions.

For example, Shell’s sustainability report emphasizes the company’s actions to manage and reduce their GHG emissions through various initiatives. Similarly, a proactive approach like Sanofi’s climate change roadmap to net-zero can serve as an inspiration for other businesses looking to reduce their Scope 2 emissions.

Furthermore, setting ambitious yet achievable targets and publicly reporting on progress helps maintain accountability and provides transparency to stakeholders. It can also open up new opportunities for collaboration with other companies dedicated to reducing their carbon footprint.

In conclusion, understanding and managing Scope 2 GHG emissions is a critical part of a company's ESG strategy. Accurate measurement, transparent reporting, and effective reduction strategies not only contribute to mitigating climate change but also enhance a company's reputation and competitive edge in a market increasingly focused on sustainability.
