That seems to be Gates' strategy - reduce your emissions when you can, and buy carbon offsets to help justify when you can't. While many people and companies certainly can - and should - make strides to reduce their carbon footprint, the argument goes, you may not be able to completely cut carbon emissions to zero. One popular rationale: Buying carbon offsets is better than doing nothing at all. Global spending on carbon offsets could increase from roughly $300 million in 2018 to as much as $100 billion by 2030, according to the Institute for International Finance's Taskforce on Scaling Voluntary Carbon Markets. Other critics claim that carbon offsets are mostly a convenient way for corporations and billionaires to justify their pollution, rather than reducing their emissions.ĭespite that, the offsets only seem to be getting more popular, especially as organizations and governments commit to massively reducing their emissions. Last month, environmental group Greenpeace called for an end to carbon offsets, echoing skeptics who worry that carbon offsets are diverting funding from long-term climate solutions. But an April study by San Francisco-based nonprofit CarbonPlan found that the state significantly overestimated the climate value of its efforts, and that its offsets "do not reflect real climate benefits." In 2019, a ProPublica report discovered multiple examples of programs that sold carbon offset credits for carbon reduction work that never ended up happening.Ĭalifornia is attempting to offset its carbon emissions by investing heavily in its forests, as part of its effort to reach carbon neutrality by 2045. There's no simple "yes" or "no" answer, but some experts have expressed deep skepticism over carbon offsets in recent years - specifically regarding their effectiveness and reliability. The average driver could theoretically cover their car's carbon footprint for under $100 per year: Carbon offsets typically cost between $2 and $20 per metric ton of emissions removed, according to a Bank of America research note published in September. You can buy credits from companies and programs that plant trees or fund renewable energy projects, or even from farmers who reduce or capture methane emissions from livestock. Individuals often use them to offset the carbon burned from driving cars or getting on flights. The average passenger car produces about five metric tons of carbon dioxide annually, the EPA says.Ĭorporations or governments might buy offsets to justify manufacturing products in a factory. One carbon offset credit supposedly equals one metric ton of carbon dioxide, or a comparable amount of other greenhouse gases, removed from the air.ĭriving a car from San Francisco to Atlanta, almost 2,500 miles, produces roughly one metric ton of carbon dioxide, according to an estimate by the Environmental Protection Agency. In theory, carbon offsets help balance your carbon footprint by funding environmental projects that reduce greenhouse gases in the atmosphere.
