How Much Does America Contribute To Global Warming

Climate change is one of the most troubling environmental issues we face today, and America has a responsibility to play an active role in curbing the ever-growing carbon emission problem. According to the latest report from the Environmental Protection Agency (EPA), the United States contributes close to 14 percent of human-induced global greenhouse gas (GHG) emissions. This figure is the second largest contributor on a global scale following China, making the US a major player in the global climate change crisis. But what are the reasons for America’s disproportionate share of GHG emissions and what can be done to start tackling the issue?

The majority of the US GHG emissions are caused by the use of fossil fuels to generate electricity, produce various raw materials, fuels, and products, and provide transportation services. Energy consumption and related GHG emissions have grown significantly over the past few decades due to the population growth, increased urbanization, and advances in technology that have made it easier and more affordable to access energy. Additionally, the US is home to some of the most prolific energy-intensive sectors, such as aviation, marine, and industrial industries. These industries account for roughly a quarter of US emissions and are some of the most difficult sectors to decarbonize due to the immense cost and complexity of implementation.

To reduce America’s contribution to global warming, the EPA has proposed several strategies to reduce GHG emissions, such as regulations and standards, investments in renewable energy, and financial incentives. The EPA’s Clean Power Plan and the implementation of renewable portfolio standards have been designed to reduce carbon pollution from power plants, while the Energy Efficiency and Conservation Block Grant program has been set up to reduce energy demand from buildings and the transportation sector. The EPA also recently announced the finalized Safer Affordable Fuel Efficient (SAFE) vehicles rule, which requires automakers to meet stringent fuel efficiency standards. At the same time, the federal government has invested heavily in the development of renewable energy sources such as wind and solar, with nearly $50 billion spent in fiscal year 2020.

It is clear that the US is taking steps to address their GHG emissions crisis, and the EPA estimates a cumulative reduction of 1.6 billion metric tons of carbon in 2030 due to all the various initiatives. However, the US still has a long way to go, and each person should be mindful of their own energy consumption and emissions. By actively pursuing energy-efficient practices, using public transportation, and purchasing renewable energy sources, we can all do our part in reducing our carbon footprint. Additionally, any public or private investments in low-carbon technology and renewable energy sources can further reduce the US’s contribution to global warming.

It is essential for all countries to do their part in reducing global GHG emissions, and the US is no exception. The government must continue to invest in renewable energy and pursue the implementation of similar laws and standards, while businesses and individuals must also strive to reduce their own carbon footprints to create a sustainable future. If we all come together and focus on curbing GHG emissions, then perhaps in the years to come, we can avoid the worst-case-scenarios of climate change and further secure a safe and healthy environment for future generations.
