Economic analysis released by the California Air Resources Board in 2016 shows that achieving their 2030 carbon reduction target with market-based policies costs $1.7 billion, while a regulation-based approach costs $9.7 billion.
The analysis shows that market-based policies can achieve the same carbon reduction target as regulatory policies, but at an 80% cheaper cost.
A 2013 study finds that reducing global greenhouse gas emissions avoids the risk of storms with Hurricane Sandy-like strength occurring roughly every year by 2050 along coastal regions in Virginia, Maryland, Delaware, and New Jersey.
The study shows that if no global action is taken, sea level rise will cause the annual odds of a Hurricane Sandy-strength storm hitting Atlantic City to increase from roughly 1-in-25 today to about once a year by 2050, but if we do significantly cut emissions, the odds increase to a more manageable 1-in-10.
Hurricane Sandy's $60 billion cost is greater than the entire proposed annual budget for the U.S. Department of Homeland Security for 2017.
The average American currently eats over a pound of beef each week (roughly equal to 4 burgers), and beef is between five and ten times worse for the climate than chicken.
The U.S. produces one-fifth of the world's beef, which is responsible for nearly 10% of global greenhouse gas emissions.
Thus, reducing beef consumption to 1 burger per week (the maximum amount consistent with a sustainable global emissions level) would eliminate 1.5% of global greenhouse gas emissions.
A 2015 study finds that reducing global greenhouse gas emissions can save nearly half of Hawaii's coral reefs, whereas failing to reduce emissions will result in a complete loss of Hawaii's coral reefs.
About 38% of the ocean around Hawaii is covered by coral reef—if we don't reduce emissions, Hawaii will risk losing all of its coral reefs by 2100, but if we do cut emissions, Hawaii would keep about 15% coral reef cover.
Reducing global emissions would provide between $10 and $30 billion in benefits to Hawaii between today and 2100 due to increased tourism and sustained local fisheries.
