AI and Sustainability: How Tech Is Transforming Carbon Accounting

Artificial intelligence (AI) is rapidly transforming industries worldwide, and its potential in sustainability is particularly noteworthy. While AI has become synonymous with increased productivity and efficiency, it also holds promise in combating climate change. One area where its impact is increasingly felt is carbon accounting—a process for organisations to measure, reduce, and report their greenhouse gas (GHG) emissions.

Despite growing awareness of climate issues, carbon accounting faces significant challenges, from inaccurate data to the complexities of tracking value chain emissions. AI offers innovative solutions to overcome these barriers, paving the way for organisations to achieve their sustainability goals and contribute meaningfully to global climate action.

The Evolution of Carbon Accounting

Carbon accounting has evolved significantly over the years. Initially, the focus was on direct emissions (Scope 1) and emissions from purchased energy (Scope 2). However, growing awareness of supply chain impacts has shifted attention to indirect emissions (Scope 3), which often make up the majority of an organisation’s carbon footprint.

This evolution has been driven by several factors:

• Regulatory frameworks like the GHG Protocol and CSRD, which require more comprehensive reporting.
• Increasing stakeholder expectations for meaningful climate action from investors, customers, and employees.
• Advancements in technology that have expanded the scope and precision of data collection and analysis.
  

While these developments have expanded the scope of carbon accounting, they have also made it more complex and resource-intensive—highlighting the need for innovation.

Challenges in traditional carbon accounting

Traditional carbon accounting methods, while foundational, often struggle to meet the demands of today’s sustainability challenges. Key limitations include:

1. Scope 3 complexity

Scope 3 emissions—those occurring across the supply chain—are notoriously difficult to measure due to:

• Data Inconsistencies: Suppliers may use varying reporting methods, making data unreliable.
• Transparency Issues: Many suppliers lack systems to track and share emissions data.
• Reliance on Estimates: Without primary data, companies default to generic averages that don't measure actual emissions accurately.
  

2. Poor data quality

Carbon accounting data is often fragmented, inconsistent, or incomplete. Spend-based data offers only rough approximations while activity-based data, though more accurate, requires significant effort to collect.

3. Lack of real-time insights

Traditional methods rely on periodic reporting, leading to decisions based on outdated information. This reactive approach limits an organisation’s ability to respond dynamically to changes in emissions patterns.

How AI transforms carbon accounting

AI is revolutionising carbon accounting by addressing its most persistent challenges and enabling organisations to adopt a more proactive approach.

Improved data collection and analytics

AI integrates and standardises data from multiple sources, such as internal systems, supplier reports, and external databases. This ensures accuracy, reduces manual errors, and improves the consistency of emissions reporting.

For example, AI carbon emissions tools can identify hotspots in supply chains, consolidate supplier data into uniform formats, and calculate emissions with precision. These automated processes save time and free up resources for more strategic sustainability initiatives.

Predictive modelling for better planning

Using AI, carbon emissions can also be forecasted based on historical data and real-time inputs. Organisations can use these predictions to estimate emissions from planned projects, set achievable reduction targets aligned with realistic timelines, and evaluate the long-term impact of various decarbonisation strategies before implementation.

For instance, AI can model the emissions impact of switching to renewable energy sources or adopting new operational practices, empowering organisations to make informed decisions before implementation.

Real-time monitoring and insights

AI-powered systems, including Internet of Things (IoT) sensors, enable continuous tracking of emissions. This real-time data provides organisations with immediate insights into inefficiencies or unexpected emissions spikes, allowing for timely adjustments and ongoing optimisation of operations.

Addressing the downsides of AI

While AI offers transformative benefits, its implementation must account for certain challenges to ensure reliability and sustainability.

Data bias

AI carbon emissions tools are only as reliable as the data they’re trained on. Biased or inaccurate data can lead to flawed insights, undermining emissions reporting and sustainability efforts. Organisations can mitigate bias by:

• Collaborating with trusted data sources: Ensuring input data comes from verified and reputable databases.
• Prioritising transparency: Choosing platforms that explain how data is processed and which factors influence results.
• Maintaining human oversight: Pairing AI outputs with expert validation to ensure alignment with organisational goals.
  

AI’s carbon footprint

AI technologies require substantial computational resources, which can contribute to emissions if powered by non-renewable energy. Selecting vendors that prioritise sustainability and efficiency ensures that the environmental impact of AI remains minimal.

The benefits of AI in sustainability

AI offers significant advantages for businesses aiming to align carbon management with their sustainability goals:

1. Improved accuracy: Replacing unreliable estimates with precise calculations in measuring emissions improves the credibility of reporting, ensuring organisations can meet regulatory requirements with confidence.
2. Reduced costs: Automating resource-intensive tasks enables organisations to allocate resources toward strategic sustainability initiatives. This helps makes carbon accounting accessible to small and medium-sized enterprises (SMEs) with limited budgets.
3. Scalability: As organisations grow, AI-powered tools adapt to increasing complexity, providing consistent and actionable insights regardless of scale.

The future of AI in carbon accounting

AI will continue to reshape how organisations approach sustainability. Its future potential includes enabling global collaboration through standardised reporting, identifying cost-effective decarbonisation strategies, and replacing static reports with real-time dashboards.

By addressing traditional challenges and enabling proactive decision-making, AI empowers organisations to achieve net-zero targets and lead the way in meaningful climate action.
