FAQ

Why should a company purchase carbon credits?

In addition to reducing their own value chain emissions over time, a critical component of a company’s holistic sustainability strategy is to drive immediate impact through high-quality carbon credits. Carbon credits can provide significant business benefits:

• Build Trusted Brand Value: Consumers increasingly support brands that align with their personal values and are demanding that companies demonstrate environmental responsibility. Amazon sees an 8.4% average increase for products after they’re certified as “Climate Pledge Friendly”, and up to 12.2% for lower priced products.
• Align with Stakeholder Expectations: Across all stakeholder groups, an average of 79% are pressuring companies to increase climate action.
• Prepare for Regulations & Mitigate Risk: Companies that invest in carbon credits as part of a holistic carbon reduction strategy are able to mitigate the scrutiny that will accompany these disclosure requirements and position themselves as leaders in the marketplace.
• Unlock Operational Efficiencies & New Opportunities: Companies that are already using carbon credits are 2x more likely to be decarbonizing year-over-year.
• Drive Immediate Impact: Implementing internal decarbonization strategies is vital, but it can be complex, costly, and time-consuming with delayed ability to drive climate benefits. High-integrity carbon credits offer an affordable way to deliver climate impact now.
• Build A Sustainable Future: Investing in these solutions now sends the demand signal and provides needed investment for these technologies to scale. By acting now, you help build up the supply necessary for the future and secure more affordable market pricing that will make it possible for us to meet our climate needs.

When is the right time for a business to start purchasing carbon credits?

A business can purchase carbon credits in multiple ways, depending on where in their climate journey they are.

• If you’re just getting started, you can use carbon credits to offset specific climate initiatives like employee travel for an event or offsetting emissions from the production of a specific product. 
• If you’re more mature in your journey, you can commit to offsetting your corporate emissions and setting science based targets and sustainability goals. 
  
  • This would involve using carbon accounting tools to get an accurate emissions data measurement according to the Greenhouse Gas Protocol.
  • Once you have an accurate measurement of your emissions data, you should find ways to decarbonize within your value chain such as transitioning to renewable energy sources.
  • While companies may have to wait longer for medium or long term operational changes to be implemented, carbon credits are the solution to achieving immediate and affordable climate impact.
• If you’re a trailblazer, you can go beyond offsetting your operational emissions to support future development of climate solutions with offtake agreements and forward purchases.
