PARIS CLIMATE AGREEMENT - Navigating the Path to a Low-Carbon Future: Internal Carbon Pricing (A Financial Tool)

The accounting profession plays a pivotal role in steering organizations toward a low-carbon future. By leveraging their expertise in financial analysis, reporting, and strategic planning, accountants can drive sustainable practices and facilitate the transition to a net-zero economy.

Climate change has become one of the most pressing challenges of our time, evident in rising global temperatures, erratic weather patterns, and the alarming rate of glacier melting. At the core of this crisis is the growing concentration of greenhouse gases (GHGs) in the atmosphere, particularly carbon dioxide (CO₂), which is responsible for about 78% of the heat-trapping effect from these gases. Over the past four decades, CO₂ levels have risen significantly, from 339 parts per million (ppm) in 1979 to 417 ppm in 2022, a 20% increase. Industrial activities are the primary drivers, with China, United States, and India being the top emitters globally. These alarming trends demand urgent action from governments, organizations, and professionals, including accountants, toward a sustainable, low-carbon future.

The Paris Agreement and Global Commitments to Carbon Neutrality

The Paris Agreement, established in 2015, marked a pivotal global response to climate change, urging nations to take decisive action to reduce GHG emissions and limit global warming to below 2°C. India, as a signatory, ratified the agreement in 2016, pledging to reduce its GHG emission intensity by 33-35% by 2030 compared to 2005 levels, later raising this target to a 45% reduction. Additionally, India aims to achieve carbon neutrality by 2070.

For these targets to be met, every sector must contribute. Accountants, in particular, play a critical role in operationalizing these commitments. By embedding sustainability into financial systems, accountants can:

Track and audit carbon emissions to ensure accurate reporting.
Budget for carbon costs and assess their impact on financial performance.
Prepare detailed sustainability reports that showcase progress toward carbon neutrality.
Support decision-making through cost-benefit analyses of carbon mitigation strategies.

These actions position accountants as key players in bridging the gap between climate goals and organizational accountability.

Carbon Mitigation Strategies and Regulatory Frameworks

Efforts to reduce carbon emissions have accelerated over the past decade, with industries shifting to renewable energy sources like wind and solar and adopting electric vehicles in place of traditional internal combustion engines. Companies are setting net-zero targets by reducing direct (Scope 1) and indirect (Scope 2) emissions.

Scope 1 emissions are direct greenhouse gas emissions from sources owned or controlled by an organization, arising from its operational activities. Scope 2 emissions are indirect emissions from purchased electricity, and Scope 3 emissions originate from sources outside the organization's direct control, such as supply chains and product usage by customers.

Government support these goals through regulatory frameworks such as:

Carbon Taxes: Imposing taxes based on emission volumes to incentivize cleaner practices.
Emissions Trading Scheme (ETS): Setting emission limits, allowing companies below the threshold to trade carbon credits with those exceeding it.

Accountants play a critical role by:

Calculating the financial impact of carbon taxes and credits.
Forecasting future costs tied to carbon pricing.
Ensuring compliance to avoid penalties and reputational risks.

As the need to limit global warming to 1.5-2°C intensifies, carbon pricing mechanisms are becoming central to climate strategies. Accountants must be equipped to help organizations navigate this landscape, ensuring compliance, financial optimization, and a meaningful contribution to combat climate change.

Carbon Border Adjustment Mechanism (CBAM)

After ETS, the European Union introduced the Carbon Border Adjustment Mechanism (CBAM) on May 17, 2023, to address carbon leakage and align import carbon costs with the EU's Emissions Trading System (ETS). CBAM prevents unfair competition by charging for the carbon content of imported goods, adjusted to the exporting country's carbon pricing. This mechanism will significantly impact India's exports, particularly aluminium and steel. CBAM will be fully implemented by 2026, with EU importers paying the levy from that year. During the transition phase (October 2023-December 2025), EU importers must report emissions for specific goods like cement, electricity, and fertilizers, without financial penalties.

For accountants, CBAM requires:

Monitoring and reporting the carbon content of imports.
Assessing its financial impact on supply chains, especially in export-heavy industries.
Guiding carbon emissions strategies to avoid penalties.

Aligned with the EU's climate goals, CBAM ensures fair global competition, making compliance management essential for accountants.

India's Carbon Credit Trading Scheme (CCTS)

India is moving towards a national carbon market, like the EU ETS and California ETS. Amendments to the Energy Conservation Act (2022) empower the government to introduce a Carbon Credit Trading Scheme (CCTS), enabling the trading of carbon credits, each representing one ton of CO₂ equivalent (tCO₂e).

In July 2024, the Bureau of Energy Efficiency (BEE) launched a compliance system for CCTS, initially targeting four energy-intensive industries: cement, iron and steel, pulp and paper, and petrochemicals. The power generation sector will join in later phases. This initiative supports India's climate goals and commitment to reduce greenhouse gas emissions.

For accountants, CCTS introduces the need to:

Track and report carbon credit transactions for compliance.
Assess the financial benefits of carbon trading for organizations.
Develop strategies to manage emissions and minimize costs.

CCTS is crucial for India's climate commitments and offers businesses opportunities to trade carbon credits and lower their carbon footprint.

Total GHG Emissions = Direct Emissions (energy) + Direct Emissions (Process) + Indirect Emissions from Purchased Electricity & Heat - Adjusted Emissions (exported power, CCUS)
GHG Emission Intensity = Total GHG Emissions (t CO₂) / Total Equivalent Output (t or MWh)

Internal Carbon Pricing: A Strategic Tool for Decarbonization and Sustainability

Internal Carbon Pricing (ICP) is a vital tool for companies aiming to meet net-zero targets and comply with evolving regulations. By assigning a financial cost to greenhouse gas emissions, ICP incentivizes emission reductions or penalizes for continued high-emission practices, aligning sustainability with financial decision-making. Adopting ICP proactively offers a competitive edge, appealing to investors, customers, and employees focused on sustainability.

For accountants, implementing ICP involves:

Setting an internal carbon price based on emissions and carbon risk exposure.
Integrating carbon pricing into investment and operational decisions.
Preparing for future carbon pricing regulations.

Establishing an internal carbon price helps companies assess the financial impact of emissions and pursue sustainable alternatives. Accountants play a crucial role in guiding these strategies, supporting the shift to a low-carbon economy while enhancing financial performance and sustainability.

Primary types of Internal Carbon Pricing

Shadow Pricing: Shadow pricing assigns a hypothetical value to carbon emissions to evaluate risks tied to business investments, particularly in light of anticipated policies increasing emissions-related costs. This approach helps integrate these projected costs into financial planning, affecting items like net income. Shadow pricing typically ranges from $2 to $800 per ton of emissions, depending on investment and risk factors, supporting informed, long-term decision-making.

For accountants, shadow pricing helps:

Projecting financial impacts of regulatory changes.
Incorporating carbon costs into forecasts and risk assessments.
Managing investment portfolios with future carbon costs in mind.
Setting up long-term sustainability goals while aligning financial strategies with environmental objectives.

Implicit Pricing: Implicit carbon pricing reflects the cost of emissions reduction projects, such as renewable energy investments or energy efficiency improvements. Unlike explicit pricing (direct taxes or fees), implicit pricing is calculated after meeting reduction goals. Companies with climate-related targets often use this method. Some companies calculate 'Implicit carbon price' using the formula: Cost of Carbon Abatement / Tonnes of CO₂e abated.

For accountants, implicit pricing is crucial for:

Evaluating the costs of emission reduction efforts and tracking their impact.

Internal Carbon Tax/Fee: An internal carbon tax involves companies charging themselves for carbon emissions they produce, creating a fund to finance emissions reduction projects with long-term benefits. Unlike shadow pricing, which focuses on future emissions, this tax addresses present emissions.

For accountants, an internal carbon tax:

Creates a financial incentive for reducing emissions.
Supports long-term sustainability planning through dedicated funding.
Ensures adherence to internal carbon pricing mechanisms.

Internal Carbon Trading Mechanism: An internal cap-and-trade system sets a carbon emissions cap within the organization. Business units receive allowances for each ton of carbon emitted, which can be traded, introducing a tangible carbon price internally. This system is especially beneficial for large corporations with diverse operations, allowing flexibility for high-emission units while driving overall reductions. It fosters collaboration and innovation, encouraging sustainable practices organization-wide.

For accountants, internal trading mechanisms:

Track emissions and allocate allowances efficiently.
Promote collaboration to achieve company-wide emission targets.
Drive sustainability and cost-effective carbon reduction strategies.

Case Studies

ICP helps align investment decisions with decarbonization goals, enabling organizations to manage climate risks and achieve environmental objectives. Below are key examples of how companies have effectively implemented ICP to foster low-carbon practices in leading organizations.

Driving Low-Carbon Investments through a Carbon Pricing Fund: In 2015, a leading cement manufacturer in India introduced a carbon fee to generate funds for low-carbon projects. Based on low-carbon projects, the company set an ICP of $11 per metric ton of CO₂. This fee, modelled against Indian carbon regulations, incentivized reductions in energy-intensive activities. Revenue generated was allocated to a dedicated carbon pricing fund, enabling the company to bridge the viability gap for projects like a 10MW waste heat recovery plant in Odisha. This project reduced emissions by 80,000 metric tons of CO₂ annually. The company ensured that the fund's investments aligned with its renewable energy and energy productivity targets, demonstrating how financial expertise can support decarbonization.

Achieving Carbon Neutrality by 2045 with ICP Integration: A leading steel manufacturing company employs ICP as a core tool for its decarbonization strategy, targeting carbon neutrality by 2045. The company has embedded ICP into two critical processes:

Capital Expenditure (CapEx): Every capital project is evaluated using a carbon-adjusted internal rate of return. Projects must surpass a hurdle rate that includes carbon costs.
Operational Decisions: ICP is used to calculate the Total Cost of Ownership (TCO) for raw materials, incorporating emissions-related costs into procurement decisions.

By aligning investment appraisals with emissions reduction goals, the company demonstrates that sustainability is central to its business planning.

Striving for Carbon Neutrality by an IT Company: A global IT company in India aims to achieve carbon neutrality through internal carbon pricing. Its strategy focuses on reducing electricity consumption by 50% (per capita, 2008-2018), switching to green power for remaining needs, and investing in offset projects for unavoidable emissions. In 2016, the company worked with WRI India to establish an internal carbon price of $10.50 per metric ton of CO₂, targeting its primary emissions from purchased electricity. The price was based on electricity costs, energy efficiency and renewable measures, and offset procurement costs. This mechanism encourages business units to prioritize renewable energy investments, supporting the goal of 100% green electricity use.

Challenges & Limitations

While Internal Carbon Pricing (ICP) offers immense potential to drive sustainability, it also presents certain challenges and limitations that organizations must address for effective implementation. A major challenge lies in accurately measuring and monitoring emissions data. Reliable data is essential for setting a meaningful internal carbon price. However, collecting such data is resource-intensive and requires robust systems, particularly in large, diverse organizations.

Another limitation is the inconsistency in regional regulations. Variations in carbon policies across jurisdictions can complicate the integration of ICP into global operations. Such discrepancies may undermine the intended benefits of aligning business practices with broader climate goals.

Fluctuating carbon market prices add to the complexity. Companies often struggle to set an internal price that balances short-term financial performance with long-term sustainability objectives. These price uncertainties can deter investments in low-carbon technologies and hinder effective risk mitigation.

The lack of a well-established culture of sustainability within organizations further compounds the issue. Without a clear commitment to sustainability from leadership, ICP implementation may lack the necessary support and strategic alignment.

Additionally, the initial costs of adopting low-carbon technologies and adapting business models can strain financial resources. Companies may hesitate to prioritize sustainability initiatives over immediate profitability, especially in competitive markets.

Lastly, market and policy uncertainties create challenges in forecasting the long-term impact of ICP. Shifts in government policies or global economic conditions can affect the relevance and effectiveness of internal carbon pricing strategies.

Addressing these challenges requires a proactive approach. Investing in advanced emissions monitoring tools, fostering a culture of sustainability, and closely monitoring policy trends can mitigate risks. Regularly revisiting and adjusting the internal carbon price can help organizations stay agile and effective in their decarbonization efforts. By overcoming these limitations, ICP can remain a powerful tool for promoting sustainable growth and aligning corporate practices with global climate commitments.
