The United States emits approximately 5 billion metric tons of carbon dioxide equivalent every year making it one of the world’s largest polluters overall. America is the second largest CO2 emitter in the world behind China but has the highest historical cumulative emissions of any nation ever. On a per capita basis each American produces approximately 15 tons of CO2 per year which is more than double the global average significantly. The transportation sector is the largest source of US emissions accounting for 29 percent of total greenhouse gases primarily from cars trucks and airplanes. Electricity generation contributes 25 percent of emissions mainly from coal and natural gas power plants operating across the country continuously. Industrial operations including manufacturing cement production and chemical processing account for approximately 23 percent of total American CO2 emissions annually. Commercial and residential buildings contribute 13 percent of emissions through heating cooling and electricity consumption in millions of structures nationwide. Agriculture contributes approximately 10 percent of US greenhouse gas emissions from livestock methane fertilizer use and soil management practices on farms. The United States has pledged to reduce emissions by 50 percent below 2005 levels by the year 2030 under the Paris Climate Agreement. Achieving emission reduction goals requires massive investment in renewable energy electric vehicles energy efficiency and carbon capture technologies across all sectors.
