Carbon Credit Registries & Marketplaces
Once you have measured and reduced your Scope 3 emissions as far as possible, high-integrity carbon credits can help address the unavoidable remainder. Use the buttons below to go directly to independently operated, verified registries and marketplaces where your finance or treasury team can source and retire credits.
Reduce first, offset the remainder
The Science Based Targets initiative (SBTi) Net-Zero Standard requires 90%+ actual emission reductions before credits are used for any residual emissions. Credits are a complement to — never a substitute for — real reductions. EZScope3 tracks your actual reductions and points you to credits only as the final step.
