The main purpose of this ongoing blog will be to track United States extreme or record temperatures related to climate change. Any reports I see of ETs will be listed below the main topic of the day. I’ll refer to extreme or record temperatures as ETs (not extraterrestrials).😉
Main Topic: Defining “Net Zero” Via Climate Central
Dear Diary. The climate crisis has brought to the fore many new terms, some of which can go over the heads of the general public that is just beginning to take climate change seriously. That’s a shame because complicated nomenclature can turn off those thinking that subject matter is too complicated; thus, they are turned off towards more educated learning. I’ve known for decades that there is a great gulf between scientists and the public, some of whom have a limited education.
It’s up to scientists and experts to explain any acronyms or terms that may confuse people they are trying to win over to the cause of mitigating climate change. I really frown on individuals who get stuck in their proverbial ivory towers, that write up peer reviewed research but never bother to explain what they have uncovered via at least an easy to read press release. This is not to write that all periodicals be dumbed down, succumbing to a failing educational system, just that some simple explainers for some uncommon terms are necessary. Today let’s concentrate on one term that can cause confusion, which is “net-zero,” referring to carbon emissions. Here is a good explainer put out by Climate Central earlier this month, which also suggests what needs to happen to attain the goals behind this often used term in the climate community.
What is Net Zero?
DEC 2, 2020
To avoid worsening climate change impacts, we need to limit emissions, and that means getting to “Net Zero.”

Net Zero by 2050
- The term “net zero” means that any greenhouse gas emissions released are balanced by an equal amount being taken out of the atmosphere.
- The Paris Climate Agreement created goals to limit the increase in global temperatures to well below 2.0°C (3.6°F) above pre-industrial levels, and to aim to curb the temperature increase to 1.5°C (2.7°F). To do this, global greenhouse gas emissions need to be cut in half by 2030, and reach “net zero” by mid-century for the 1.5°C degree target.
- Core areas of the U.S. economy—transportation, electricity, industry, agriculture, and commercial and residential buildings—need to undergo major transformation in order to get to net zero.
- Most of the pathways to keeping global temperature increases below 2°C—and every pathway to stopping at 1.5°C—incorporates absorbing carbon emissions from the atmosphere through carbon capture and storage, or sequestration.
Read Climate Matters’ new solutions brief on getting to net zero.
The planet needs to go on a carbon diet. Our current catastrophes—devastating wildfires, stronger hurricanes, and rising seas—are consistent with the warnings scientists made in the 1980s and 1990s. Past burning of fossil fuels, including oil, coal, and natural gas, has released greenhouse gases into the atmosphere and caused the earth to warm by 2° Fahrenheit (a bit more than 1° Celsius) since the pre-industrial era (1880-1900).
In 2015, the Paris Climate Agreement set goals for countries to try and limit the increase in global warming to well below 2.0°C (3.6°F) above pre-industrial levels to avoid worsening impacts of climate change, and pursue efforts to limit the temperature increase to below 1.5°C (2.7°F). According to the Intergovernmental Panel on Climate Change (IPCC), in order to reach these targets, global greenhouse gas emissions need to be cut in half by 2030, and reach “net zero” by mid-century for the 1.5°C degree target. This not only requires drastically cutting our greenhouse gas emissions fast, but removing CO2 from the atmosphere.
The term “net zero” simply means that any greenhouse gas emissions released are balanced by an equal amount being taken out of the atmosphere.
Scientists, engineers, and other researchers are exploring pathways and models to figure out what needs to happen over the next few decades to get the U.S. to net zero. The Net-Zero America Project (NZAP), being released in December 2020, models several technology pathways to reach net-zero GHG emissions by mid-century. Another initiative, the Zero Carbon Action Plan (ZCAP), released in October 2020, looks at decarbonizing six key economic sectors. And there are other net-zero plans and carbon management solutions, including reports from the Center for Climate and Energy Solutions.
While their modeling and projections may incorporate different inputs and show different outcomes, all these projects highlight the same core areas of our economy that need to undergo major transformation in order to get to net zero:
- Creating carbon-free electricity
- Electrifying transportation
- Adopting energy efficiency measures and electrifying our buildings
- Decarbonizing industry and manufacturing
- Transforming our farming and food habits
Most pathways to keeping global temperatures in check—and every pathway to stopping at 1.5 degrees—incorporates absorbing carbon emissions from the atmosphere. Carbon dioxide is the only greenhouse gas that can be taken out of the atmosphere and stored; doing it at a scale large enough to make a difference is a challenge.
In the next few months, Climate Matters will release a series of climate solutions issue briefs tackling these topics. We’ll explain the technologies and policies that support net-zero goals, look at where we are and where we need to go in our states and cities, and provide you with resources and experts to help you with your reporting.

POTENTIAL LOCAL STORY ANGLES
Where are net-zero commitments being made?
In the U.S., a growing number of state governments have committed to GHG reduction targets through legislation or by executive order. Twenty-three states plus the District of Columbia have adopted GHG reduction targets to address climate change. Twelve states now have net-zero mandates by 2050. As of July 2020, 19 countries and the European Union had adopted net-zero targets. The N.C. Clean Energy Technology Center at North Carolina State University maintains DSIRE, a comprehensive database on state and local incentives and policies for renewable energy and energy efficiency. And the National Conference of State Legislatures describes which states have set renewable portfolio standards.
How much energy does my state produce from renewable energy sources like solar or wind?
The U.S. Energy Information Administration (EIA) produces monthly reports of national and state energy statistics, and also has an interactive state energy portal that provides maps, charts, and state dashboards showing how much of your state’s electricity is supplied by renewable, nuclear, or fossil fuel sources. And you can use Climate Central’s WeatherPower tool to find your local wind and solar electricity generation and forecast, as well as downloadable and customizable graphics.
Are there more electric vehicles on the road near you?
Electric vehicles (EVs) can not only reduce greenhouse gas emissions and other air pollutants, but potentially act as battery storage with vehicle-to-grid systems. The U.S. Department of Energy’s Alternative Fuels Data Center has statistics on EV registrations, charging locations, incentive programs, and other data by state. And you can check here to compare conventional, hybrid, and electric vehicle emissions by state, based on local sources of electricity.
The SciLine service, 500 Women Scientists, or the press offices of local universities may be able to connect you with local scientists who have expertise on net-zero targets and renewable energy in your area. The American Association of State Climatologists is a professional scientific organization composed of all 50 state climatologists. You can also contact experts at your Regional Climate Center, a program under NOAA’s National Center for Environmental Information (NCEI). The Solar Energy Industries Association (SEIA) has an interactive map that allows you to find local energy companies in your state, and downloadable fact sheets for each state on solar production and state incentives. Windpower Engineering & Development is a quarterly trade publication that has a searchable database of wind energy projects and their manufacturers around the country.
