How Do Carbon Credits Help Reduce Emissions?
Carbon Credits Help Reduce Emissions
Carbon credits are tradable “rights” linked to activities that lower the amount of carbon dioxide (CO2) in the atmosphere. Individuals, companies and governments can buy these credits to offset their own emissions by funding projects that fight climate change elsewhere. This is known as carbon trading. There are three types of carbon credit: carbon reduction, carbon avoidance and carbon removal.
The vast majority of credits sold are for carbon reductions, which involve activities like energy efficiency investments or reducing fossil fuel use. Reduction credits make up about 22% of the certified carbon credits on the voluntary market today, and are generally easier to measure and verify than carbon credits from carbon removal projects.
To earn a carbon.credit, projects must be independently audited to ensure that each metric tonne of CO2 avoided or reduced has actually taken place. These credits are issued by a variety of entities, including governments and independent certification bodies like the Gold Standard. They are then traded on the carbon market.
How Do Carbon Credits Help Reduce Emissions?
Many organizations have ambitious climate targets that they can’t meet through internal reductions alone. To meet these goals, they need to fund external decarbonization projects that reduce their unavoidable emissions. These projects are referred to as “carbon offsets.” When bought, these carbon credits enable businesses to compensate for their unavoidable emissions while still meeting their ambitious targets.
As the urgency for action on climate change reaches new heights, the world is facing record-high carbon emissions. These emissions must be cut to help prevent the most serious impacts of global warming. But the way to do this is not straightforward. It’s hard to make reductions without cutting back on other activities, and this can lead to trade-offs with economic growth or even health benefits. And there are often concerns that companies are using carbon credits to avoid taking action on their own emissions, or that the carbon credit industry isn’t sufficiently transparent or trustworthy.
For these reasons, the carbon market needs to be made more robust and transparent. The best way to do this is to establish rigorous standards that are applied consistently by all parties in the market. For example, the Gold Standard and Verra are both independent nonprofits that have established carbon standards that include accounting methodologies specific to each type of project, independent auditing and a registry system.
These standards are key to making sure that carbon credits are genuinely helping to reduce emissions, rather than simply moving them around the world. A more transparent and stable carbon market can also help build trust in carbon reduction initiatives, encouraging businesses to invest in them as well.
In the meantime, as the global climate crisis escalates, we need to continue accelerating our efforts to reduce greenhouse gas emissions and build a more sustainable economy. This will require a combination of carbon pricing policies, from national and regional emissions trading systems to carbon taxes. In addition, we need to push for more rigorous scientific targets based on the most up-to-date science.
