Internal carbon pricing generally takes one of three forms:
- An internal carbon fee is a monetary value on each ton of carbon emissions, which is readily understandable throughout the organization. The fee creates a dedicated revenue or investment stream to fund the company’s emissions reduction efforts. The observed price range for companies using an internal carbon fee is from $5-$20 per metric ton.
- A shadow price is a theoretical price on carbon that can help support long-term business planning and investment strategies. This helps a company prioritize low-carbon investments and prepare for future regulation. While the observed price range for companies using a shadow price is from $2-$893 per ton, most companies use a shadow price higher than the current government levels of $10 per ton.
- An implicit price is based on how much a company spends to reduce greenhouse gas emissions and/or cost of complying with government regulations. For example, it can be the amount a company spends on renewable energy purchases or compliance with fuel economy standards. It helps companies identify and minimize these costs, use the information gained from this to understand their own carbon footprint. For some companies, an implicit carbon price can set a benchmark before formally launching an internal carbon pricing program.
Many companies use a hybrid model of complementary approaches that combine these different attributes.
Corporate pricing is most meaningful if embedded in a company’s business strategy. Some companies, such as Microsoft, use revenue from its internal carbon fee to fund renewable energy, energy-efficiency, and other projects needed to reduce emissions; research into emissions reduction technology; and raise employee awareness of climate risks and opportunities. Others, such as Shell, BHP, and BP, embed a shadow price in their business strategy by shifting investments in low-carbon assets or even stopping projects with high-carbon intensity.
Internal carbon pricing can serve as an important risk-mitigation tool with multiple benefits beyond the company’s operations, customers and communities. As companies are taking leadership on climate action, it can be combined with other approaches to help advance the low-carbon transition.
