Carbon offsets are credits from carbon offset initiatives to reduce greenhouse gas emissions contributing to global warming. Carbon credits lower emissions by requiring projects to implement activities that increase the absorption of climate-warming pollutants into carbon sinks or by decreasing GHG emissions from sources such as landfills or farms.
Fremont, CA: A carbon offset is a reduction or elimination of carbon dioxide or other greenhouse gases (GHG) used to compensate for emissions from different sources. Offsets are expressed in metric tons of carbon dioxide equivalent (mtCOe), while many organizations use pounds.
Reducing emissions through carbon offsetting is critical to achieving global net zero targets; it is accomplished through carbon offset projects that create carbon credits that may be sold and utilized to mitigate GHG emissions.

Carbon credits are generated by programs that help to maintain forests, capture methane, build wind farms, and provide water purification systems. Each program aims to eliminate carbon dioxide or avoid future emissions. Many promote the development of communal wellness.
All projects can be classified into one of three major categories:
Nature-Based Projects
Nature-based carbon offset systems have the potential to deliver 20% of the climate mitigation required between now and 2050, assuming a two °C warming scenario.
These efforts minimize carbon emissions while protecting biodiversity and creating jobs in local communities. This category's offset initiatives are primarily forestry-based, aiming to protect forests, repair deterioration, and promote sustainable forest management practices.
Sustainable Infrastructure
Sustainable infrastructure projects include those that focus on developing and growing renewable energy sources such as wind, solar, hydropower, and geothermal, as well as those that use methane extraction for energy and nitrous oxide abatement technology, compost, biomass, and biogas.
The primary benefit of these initiatives is reducing dependency on fossil fuels, which improves air quality, reduces disease in local populations, and stimulates the local labor market.
Improved Health and Livelihood
Climate change can cause food production, air quality, access to clean water, and safe housing to suffer. Underrepresented communities in the global south are particularly vulnerable.
Improved livelihood programs equip families and communities in need with fuel-saving cookstoves, household solar and biodigesters, and water treatment technology. These strategies contribute to improved air and water quality, lower disease rates, and lower household costs.
