Our latest annual stocktake shows the world is on track to reach a new record: 37.4 billion tonnes of CO emitted from fossil fuels in 2024. This is an increase of 0.8% from the previous year.

What’s not to like about improving sustainability and protecting the environment while saving energy and money—and best of all, no equipment or software expenditures are necessary.

More than 300 businesses have signed an open letter calling on the Biden administration to reduce greenhouse gas emissions in the United States to at least half of 2005 levels by 2030. That would nearly double a previous target set by former President Barack Obama in 2015, who pledged a 25 to 28% reduction by 2025.

The United States is not currently on track to meet either goal.

The signatories include some of largest companies in the United States, including Walmart, Apple, McDonald's and Starbucks. "A bold 2030 target is needed to catalyze a zero-emissions future, spur a robust economic recovery, create millions of well-paying jobs, and allow the U.S. to 'build back better' from the pandemic," the letter said, echoing the president's economic recovery slogan.

A 50% reduction target would put the Biden administration in line with what groups such as the United Nations and National Academies of Science say is necessary to mitigate the worst impacts of climate change.

In a March statement calling for the same reductions target, the environmental advocacy group Natural Resources Defense Council said such a plan would "help pull the country out of the pandemic-induced recession by putting millions of Americans to work" and inspire more ambitious international climate action ahead of a major United Nations climate conference this November.

Like President Joe Biden's campaign promise to guide the United States to carbon-neutrality by the middle of the century, a 50% emissions reduction target would require steeper emissions cuts than the country has ever achieved.

In 2019, greenhouse gas emissions were approximately 13% below 2005 levels, a decrease of just 1.8% from the previous year.

The Biden administration has identified climate action as one of its top four priorities and has named prominent, experienced Washington insiders, including former Secretary of State John Kerry and former EPA administrator Gina McCarthy, to oversee climate policy efforts at the White House.

As NPR's Danielle Kurtzleben has previously reported, activists on the left are cautiously optimistic about the administration's climate plan after expressing doubts about Biden's climate record during the Democratic primary.

Sunrise Movement, a youth-led climate group that champions the Green New Deal, gave candidate Biden's initial climate plan an "F" grade. Now, the group's executive director Varshini Prakash is publicly celebrating his administration's latest climate-focused $2 trillion infrastructure bill — including its commitment to spend 40% of the infrastructure plan's money on disadvantaged communities and launch a jobs program called the Civilian Climate Corps.

New York Democratic Rep. Alexandria Ocasio-Cortez told NPR earlier this month that she feels that Biden has ultimately come around to the side of progressives on climate issues. She said: "As much as I think some parts of the party try to avoid saying 'Green New Deal' and really dance around and try to not use that term, ultimately, the framework I think has been adopted."

The emphasis on climate comes as a sharp departure from the Trump administration, which withdrew the United States from the Paris Agreement and set no emissions reductions targets.

Signatories to the Paris deal, which Biden rejoined on the day he was sworn into office, are all required to set these targets — formally known as nationally determined contributions, or NDCs.

The agreement also encourages nations to revise their goals every five years, in hopes that the proposals become more ambitious as the cost of environmental reform goes down.

Since the Paris agreement was first agreed to in 2015, though, just fifty of the deal's nearly 200 signatories have submitted revised targets. A recent U.N. analysis of international climate action found that many countries were doing far too little to reduce emissions for the world to avoid the worst effects of climate change.

So far, the White House has not indicated exactly how ambitious their plan will be. An announcement is expected in the coming days as the White House prepares for its Earth Day climate summit with world leaders, scheduled for Thursday, April 22.

There is no substitute for dramatic reductions in greenhouse gas emissions to mitigate the negative consequences of climate change, a National Research Council committee concluded in a two-volume evaluation of proposed climate-intervention techniques.

Achieving net-zero carbon emissions in the U.S. by 2050 is feasible and would not only help address climate change but also build a more competitive economy, increase high-quality jobs, and help address social injustice in the energy system, says a new report from the National Academies of Sciences, Engineering, and Medicine.

In an interview, NAE President John Anderson discusses the national and global transition to net-zero carbon emissions and how engineers — and NAE in particular — can support that shift. Energy Transitions is the theme of NAE’s annual meeting this year, taking place Oct. 2-3.

More than 100 world leaders converged upon New York City today to discuss international efforts to reduce carbon emissions and combat climate change. The list of speakers at the UN Climate Summit included U.S. President Barack Obama, UK Prime Minister David Cameron, Brazilian President Dilma Rousseff, French President François Hollande, and Chinese Vice Premier Zhang Gaoli.

Global emissions were unchanged last year, the first time that’s happened amid economic growth in four decades, according to the International Energy Agency.

President Barack Obama ordered the federal government to reduce greenhouse gas emissions by 40 percent from 2008 levels over the next 10 years by shifting to renewable energy sources such as solar power.

Carbon emissions in 2014 remained at the previous year’s levels of 32.3 billion metric tons — a milestone that points to the impact worldwide renewable energy investment is having in the face of a 1.5 percent annual increase in global energy consumption, according to a new report from REN21. The tenth annual Renewables 2015 Global Status Report cites “increased penetration of renewable energy” and improvements in energy efficiency as the chief reasons for the noted emissions stabilization.

With the dramatic reduction in car traffic and commercial flights, carbon emissions have been falling around the globe. If the slowdown continues, some are estimating the world could see the largest drop in emissions in the last century.

Still, overall greenhouse gas emissions in the atmosphere are still going up and the decline will likely be smaller than what scientists say is necessary to avoid the worst impacts of climate change.

So far, the effects are just starting to appear. In China, the first country to lock down, greenhouse gas emissions dropped an estimated 25% in February as factories and industrial producers slowed output. That decreased coal burning, which has come back slowly since then.

"A month or two of shelter in place will drop carbon dioxide emissions a few percent here or there, but it won't change the year substantially unless we stay like this for some time," says Rob Jackson, environmental scientist at Stanford University.

The declines are still too small to be read by greenhouse gas observatories around the world, like the one on top of the Mauna Loa volcano in Hawaii, given the natural changes in atmosphere this time of year. Because much of the Earth's land mass is in the northern hemisphere, plants and forests there cause carbon levels to fluctuate as they bloom in the spring, drawing carbon dioxide from the air.

If countries continue shelter-at-home orders, emissions declines could be greater. The U.S. Energy Information Administration estimates U.S. emissions from gas and energy use could drop more than 7% this year, similar to a 2009 decline during the financial crisis.

Worldwide, early estimates put global emissions dropping around 4%. Still, that's less than the 7.6% the U.N. says is needed to avoid the worst impacts of climate change by limiting warming to 1.5 degrees Celsius.

To achieve those cuts, scientists say more fundamental changes are needed, like switching to renewable energy.

"This isn't the way we want to reduce our fossil fuel emissions," says Jackson. "We don't want tens of millions of people being out of work as a path to decarbonizing our economy. We need systemic change in our energy infrastructure and new green technologies."

Still, Jackson says the recent changes are providing useful insights.

"It's as if a third of the cars on the road were suddenly electric, running on clean electricity and the air pollution is plummeting," says Jackson. "It's really a remarkable experiment and it shows the benefits of clean energy."

Pollen allergy is a common cause of allergic respiratory diseases such as hay fever and asthma. A recent continent-wide study suggests that rising carbon dioxide (CO2) emissions over the last 30 years may be increasing pollen counts especially in European cities, which could have serious consequences for public health.

Although the public are largely aware of climate change, their understanding of how they produce and manage carbon is generally not sufficient to lead to changes in behaviour and lifestyle, according to a recent study. The researchers therefore recommend policy action to increase the ‘carbon capability’ of the general public.

Permafrost and wetlands in high latitudes could switch from carbon sink to carbon source by the end of the century, according to a recent study. Using a model of terrestrial ecosystems that showed how carbon is stored and released in soils at high latitudes, researchers revealed that climate change could cause these soils to release much more carbon than previously predicted.

Carbon emissions from Dutch road networks could be reduced by almost a third if more innovative materials and processes were used, a new study suggests. Researchers assessed the potential benefits associated with 10 innovations in road construction and maintenance, and compared them to conventional materials and processes.

Countries that appear to have reduced greenhouse gas (GHG) emissions through reforestation may have simply “displaced” the emissions to another country, by increasing their imports of food, timber and wood. A new EU study highlights the need to recognise this ‘loophole’ in ongoing emission targets.

Landfill taxes and ‘enhanced waste management’ practices have been introduced to reduce the amount of waste that goes to landfill and to convert waste into useful products. This study investigated the interplay of these two policy options in Belgium, generating findings that could help Europe move towards a resource-efficient, circular economy.

A recent assessment suggests that reducing black carbon emissions, produced by burning carbon-based materials, would prevent millions of premature deaths in developing countries as well as helping meet climate change mitigation targets.

Measurements of individual vehicle emissions are usually made in laboratory tests. In this study, researchers followed cars driving in real conditions to measure emissions of air pollutants, including black carbon and nitrogen oxides. The study shows that diesel cars contribute disproportionately to air pollution, and highlights the value of on-road measurements.

Flexibility mechanisms were defined in the Kyoto Protocol as different ways to achieve emissions reduction as part of the effort to address climate change issues. These fall into the following categories: Emissions Trading, Joint Implementation and Clean Development Mechanism.

However, these have been highly controversial as they were mainly included on strong US insistence and to keep the US in the treaty (even though the US eventually pulled out). Some of the mechanisms face criticism for not actually leading to a reduction in emissions, for example.

The updates to this article includes a couple of videos summarizing some concerns about cap and trade.
