According to the Food and Agriculture Organization of the United Nations (FAO), we lose over 10 million hectares of forests every single year. That’s the same as losing an area the size of New York’s Central Park every 18 minutes.
In this graphic from our sponsor LEAF Coalition, we take a look at the drastic knock-on effects of tropical deforestation: from significant greenhouse gas emissions and irreversible loss in biodiversity to the impact on the lives of Indigenous Peoples.
Global Greenhouse Gas Emissions by Economic Sector
When looking at how greenhouse gas emissions break down by sector, the agriculture, forestry, and other land use (AFOLU) sector is responsible for nearly 15% of global emissions.
Moreover, global models estimate that net emissions from land use and land use change are mostly as a result of deforestation.

From 2002-2015, a handful of commodities were responsible for 55% of all agriculture-linked deforestation. These include:
Decarbonization efforts in the U.S. are ramping up, and in 2020, greenhouse gas (GHG) emissions were lower than at any point during the previous 30 years.
However there’s still work to be done before various organizations, states, and nationwide targets are met. And when looking at GHG emissions by sector, the data suggests that some groups have more work cut out for them than others.
This graphic from the National Public Utilities Council provides the key data and trends on the total emissions by U.S. sector since 1990 .
The Highest Emitting Sectors
Collectively, the U.S. emitted 5,981 million metric tons (MMT) of CO2-equivalent (CO2e) emissions in 2020, which rose 6.1% in 2021.

The transportation sector ranks highest by emissions and has been notably impacted by the COVID-19 pandemic, which is still affecting travel and supply chains. This has led to whipsawing figures during the last two years.
For instance, in 2020, the transportation sector’s emissions fell 15%, the steepest fall of any sector. But the largest increase in emissions in 2021 also came from transportation, which is largely credited to the economic and tourism recovery last year.
Following transportation, electricity generation accounted for a quarter of U.S. GHG emissions in 2020, with fossil fuel combustion making up nearly 99% of the sector’s emissions. The other 1% includes waste incineration and other power generation technologies like renewables and nuclear power, which produce emissions during the initial stages of raw material extraction and construction.
Decarbonizing the Power Sector
The Biden Administration has set a goal to make the U.S. power grid run on 100% clean energy by 2035—a key factor in achieving the country’s goal of net zero emissions by 2050.
Industrial factories, commercial buildings, and homes all consume electricity to power their machinery and appliances. Therefore, the power sector can help reduce their carbon footprint by supplying more clean electricity, although this largely depends on the availability of infrastructure for transmission.

Today, the bulk of electricity generation, 60%, comes from natural gas and coal-fired power plants, with nuclear, renewables, and other sources making up 40% of the total.

However, progress and notable strides have been made towards sustainable energy. In 2021, renewables accounted for one-fifth of U.S. electricity generation, roughly doubling their share since 2010.
Coal’s share as a source of electric power has dropped dramatically in recent years. And partially as a result, electricity generation has seen its portion of emissions successfully decrease by 21% , with overall emissions falling from 1,880 million metric tons of CO2 to 1,482 million metric tons.
How Utilities Can Lead the Way
Should these trends persist, the electricity generation sector has a chance to play a pivotal role in the broader decarbonization initiative. And with the bulk of electricity generation in the U.S. coming from investor-owned utilities (IOUs), this is a unique opportunity for IOUs to lead the transition toward cleaner energy.
