Greenhouse gas emissions have been steadily going down since about 2008. There have been bounces where emissions go down then up then down again with the end result being lower towards the 2030 goal. During the pandemic emissions dropped significantly because a lot of activities ceased, e.g. flying and driving to work. After the pandemic emissions have risen again but they are still below pre-pandemic levels.

[Greenhouse gas] "Emissions ticked up 1.3 percent even as renewable energy surpassed coal power nationwide for the first time in over six decades, with wind, solar and hydropower generating 22 percent of the country’s electricity compared with 20 percent from coal."

"A recent report from the International Energy Agency estimated that renewables are on track to overtake coal as the largest source of electricity generation worldwide by early 2025..."
...
The "highest-emitting sectors, transportation and industry, together account for roughly two-thirds of the country’s total greenhouse gas emissions."

"Industrial emissions rose by 1.5 percent and
transportation emissions rose by 1.3 percent, the latter driven mainly by demand for jet fuel as air travel continued to recover from pandemic-era declines."
...
"The most significant increase in emissions last year came from homes and buildings, which burn fossil fuels like natural gas in furnaces, hot water heaters and other appliances. Those emissions rose 6 percent, and reached prepandemic levels. Colder-than-average temperatures early in the year led many Americans to increase their home energy use by turning up the heat."
...
"Agriculture is a major contributor to climate change, with farming activities accounting for 11.2 percent of total greenhouse gas emissions in the United States in 2020..."
...
"some good news: Last year, the country’s economic growth, measured in G.D.P., outpaced emissions growth, indicating that the economy was less carbon intensive..."

Slowly we are going to reach the target emissions. However, with transportation and industry accounting for two-thirds of the country’s total greenhouse gas emissions it is hard for us as individuals to do more. That's when joint efforts from our government and business/industry are so important.
