In the international carbon offset market, the average price of removing one tonne of CO2 from the atmosphere is still below $15 USD, nowhere near enough to cover the costs of carbon capture and storage (CCS). As Dr. Sheila Olmstead (University of Texas, Austin) explained in a recent Climate Now podcast episode, this is why CCS is one of the few cl…
 
Each year, we produce about 30 billion tonnes of concrete globally. That’s nearly 10,000 pounds, or more than 2 entire cars-worth of concrete, per person, per year. We produce enough steel to build more than 2700 Empire State Buildings annually. We produce more than 100 pounds of plastic per person, each year. And with all of this material producti…
 
Are we underestimating the potential of increased efficiency? It wouldn’t be the first time. In 2021, the International Energy Agency and the U.S. Energy Information Administration forecasted a 50% increase in global energy demand by 2050. Such forecasts have echoes of the 1970’s, when – in the middle of a global energy crisis – forecasters were an…
 
“Inertia is a hell of a thing. Inertia is there, and there is very little motivation for an incumbent to change course. So you have to have that disruption from the outside. The same thing with financial services.” - Marilyn Waite, Climate Finance Fund In the 2019/2020 fiscal year, the global climate finance sector reached a record 632 billion US d…
 
Lawrence Livermore National Lab, Princeton University, and the IPCC have all published proposed climate mitigation pathways: strategies for economically reaching net-zero emissions by mid-century for California, the U.S., and the world, respectively. And they are not alone. Any given pathway to net-zero emissions offers some combination of efficien…
 
For years we’ve been hearing that the clean energy transition is going to be expensive. But the recent working paper, Empirically grounded technology forecasts and the energy transition, suggests that the high estimates of the expense to transition to renewable energy have been inflated, and that it may in fact be cheaper to transition to renewable…
 
Among the top importers of Russian oil are the EU, Germany, Italy, The Netherlands, and France. The EU accounted for 71% of oil imports from Russia 2 months after the war in Ukraine began. But cutting off oil and gas imports from Russia completely can pose great challenges. The EU is attempting to wean off of Russian oil dependence in response to t…
 
If the international shipping sector were a country, it would be the sixth largest CO2 emitting nation in the world. Every year, 11 billion tons of goods - about 80% of all the goods we use or consume - reach us by ship, emitting nearly a billion tons of CO2 into the atmosphere in the process. And, about 40% of those goods - nearly 4.5 billion tons…
 
Soil - that mixture of degraded bedrock, decomposing organic matter, and microorganisms, that nourishes the root systems of plants and trees - already has a soil carbon bank 4x that of vegetation. And, by changing how we manage our soils, it is possible to increase their capacity for trapping CO2 in the form of organic carbonand enhance the agricul…
 
Today, 26% of the global population - about 2 billion people - live without reliable access to safe drinking water. And, as climate change worsens, the availability of fresh water will only decrease. By 2050, as many as 3.2 billion people could live in severely water-scarce regions of the world. More than half the global population will experience …
 
The U.S. Securities and Exchange Commission wants to standardize climate disclosures for publicly traded companies. What does that mean? On March 21, 2022 the SEC released a proposal for a new rule: publicly traded companies will have to provide disclosures about how the changing climate will affect their business, and how their business is affecti…
 
In the race for decarbonization, the shipping industry faces major challenges. Fuel is cheap, almost half the price of gasoline. And, most ships last between 20-25 years, meaning that the turnover to cleaner shipping could take far longer than road transportation, where the average car is only 12 years old. But there is some wind in the sails of ma…
 
One of the most efficient ways to get to a net-zero economy is to generate electricity from renewable sources, and then make as many things run on electricity as possible. But, as more end-use services (transportation, heating, industry) are electrified, and the source of electricity transitions from fossil fuels to renewables like solar and wind, …
 
In 2021 alone, more than $32 billion dollars were invested in green-technology startups, a four-fold increase from five years earlier. But how far will those dollars go? Only about 25% of venture-backed startups actually make the transition from an innovative idea to a successful business. And when we are considering green technology, choosing whic…
 
What will it take to get 100% of new car sales to be electric by 2030? Is it consumer demand? Is it political pressure? How about we just increase both? The Zero Emission Transportation Association (ZETA) is the first industry-backed coalition advocating for 100% EV sales by 2030, and they have devised a federal roadmap for reaching that goal. Joe …
 
Decarbonizing our global economy is critical to staying below the 1.5C threshold of warming, but so is reducing the amount of carbon dioxide already in the atmosphere. By 2050, we will need to remove about ten billion tonnes of CO2 every year. Currently, we are capturing and sequestering about 40 million tonnes a year - about 0.4% of what’s needed …
 
There is a lot of focus within climate tech on how to decarbonize cars—whether that be via electric batteries, hydrogen fuel cells, or other emerging technologies—but what about eliminating the need for cars altogether? How can we better design our cities and suburbs so that they are centered around humans, not cars? Cars do not need to be the prim…
 
Climate policy at the federal level is integral to mitigating the climate crisis. Unfortunately, the United States has had a hard time so far passing ambitious climate legislation. Why is that? From the outside, the situation often seems hopeless. But what does it look like from inside Washington? To find out, Climate Now spoke with Alex McDonough.…
 
Heavy-duty, long-haul trucks - known as Class 8 trucks - account for more than 1 billion tons of carbon dioxide emissions worldwide each year. Electrification, while a practical option for most of the trucking industry (see last week's episode), is not yet as feasible for long-haul Class 8 trucks. | What options might exist to decarbonize heavy-dut…
 
In 2019, medium- and heavy-duty trucks accounted for about a quarter of U.S. transportation emissions while representing less than 4% of vehicles on the road, according to the U.S. EPA. It is clear the trucking industry must decarbonize in order for the transportation sector, and the economy as a whole, to reach net-zero emissions, but which emergi…
 
Ride-sharing services currently result in 69% more emissions, on average, than the trips they displace, according to a recent study by the Union of Concerned Scientists. But, if the ride-sharing vehicles were electric, it's a whole different story. Replacing one gasoline-powered ride-sharing car with an electric vehicle (EV) has three times the cli…
 
Climate Now is kicking off our Decarbonizing Transportation series by addressing a question that looms over the electric vehicle market: how can we sustainably manufacture and recycle EV batteries? To learn about electric vehicle battery trends and challenges, we are joined by Andy Stevenson, former Special Projects Associate at Tesla and former Ch…
 
The Connecticut Green Bank, the first green bank in the US, has unlocked over $2 billion in capital toward clean energy projects and other climate solutions since it was established by the state legislature in 2011. So, what is the green bank model? How does it compare to other methods of clean energy finance? And what are their impact? Climate Now…
 
Earth's oceans play a key role in slowing climate change, absorbing nearly a third of anthropogenic CO2 emissions. And they could, potentially, absorb more. In this episode, Climate Now explores developing methods to enhance ocean-based carbon dioxide removal. What do we know about each technique, and what are the associated risks? Learn more in ou…
 
In November 2021, representatives from around the world gathered to update their climate commitments at the 26th United Nations Framework Convention on Climate Change (UNFCCC) Conference of the Parties (COP 26) in Glasgow, Scotland. The conference received substantial attention from media and climate groups around the globe, the likes of which we h…
 
Wind energy is one of the cheapest sources of energy today, but it accounts for only ~6% of global electricity generation. To limit global warming to 2 degrees C or less, wind energy will need to scale up to about 5 times its current size. | So, how can this be achieved? What are the challenges to scaling wind energy to this degree? How does off-sh…
 
Much of the focus surrounding climate action is on mitigation: how do we reduce the concentration of greenhouse gases in the atmosphere, and avoid catastrophic climate change in the coming decades? But the reality is the climate is already changing - and will continue to change even under the most optimistic mitigation scenarios. So what is being d…
 
"The [investment market] we have in place now is not working for people, it's not working for the planet, and it's actually not working for most investors." This is according to Amit Bouri, Co-founder and CEO of the Global Impact Investing Network (the GIIN), an international community dedicated to increasing the scale and effectiveness of impact i…
 
A growing population, groundwater depletion, poor water infrastructure, overuse, and water waste threaten our global freshwater supply. Throw climate change into the mix, and the water crisis is exacerbated, as precipitation becomes less reliable and average global temperatures rise. The water crisis, like the climate crisis, is projected to get wo…
 
Most climate models in use today are based upon large-scale, well-understood physical relationships that drive global temperature and precipitation trends. But the effects of complicated interactions that occur on smaller scales, which may still be significant, are harder to capture in these models. That is why Dr. Laure Zanna of New York Universit…
 
What does it take to turn an idea that could help fight climate change into a self-sustaining business? We often hear the glamorous stories of startups that have made it, but little about the struggles, the learning, and the luck required to get there. Pol Knops, Founder and Chief Technology Officer of Green Minerals, joined Climate Now to share hi…
 
How do we finance the cost of mitigating climate change, while discouraging continued use of fossil fuels? The largest public statement of economists in history argues for a carbon tax - which would charge a fee for every ton of carbon dioxide emitted. But, if one country charges a different carbon tax than another, what would happen to internation…
 
A rapidly expanding list of companies have announced plans to go "carbon neutral" or "net zero". Often, these plans include at least some offsetting of greenhouse gas emissions by purchasing credits from forest carbon offset programs. But buyers beware: our look into how forest carbon offsets are determined and sold suggests that there is a lot of …
 
For businesses, a changing climate is not just about worsening weather patterns. Businesses must be prepared for what is likely to be an era of rapidly accelerating change to many dimensions of their operations, including changes in shareholder expectations, supply chains, multi-dimensional risks to physical assets, and impacts on labor, among othe…
 
In the first episode of our two-part series, we learned how NASA's Orbiting Carbon Observatory made it to space despite overwhelming odds from David Crisp, the mission's principal investigator. Today, we released the sequel, where we explore the science of carbon dioxide remote sensing, and how the data collected by the OCO missions 2 and 3 can be …
 
On the 24th of February, 2009, David Crisp was in the control center at Vandenberg Air Force base counting down the seconds for the Orbiting Carbon Observatory to launch. It was a project he had led for a decade - and it was the first NASA mission that would measure atmospheric carbon dioxide from space. Hundreds of millions of dollars and years of…
 
Many climate change mitigation proposals are land-use intensive. Are these proposals feasible without negatively impacting biodiversity? Can we develop solutions for both the climate and biodiversity crises? There has been an historic lack of collaboration between climate and conservation efforts. To address this, the Intergovernmental Panel on Cli…
 
The climate crisis has myriad effects on American businesses, from where properties are located and their likelihood of encountering extreme weather, to where materials are sourced and potential supply-chain complications. These effects inevitably carry with them financial risks and opportunities which can impact pensions, stock markets, and busine…
 
Is there such a thing as "perfect" energy? With nuclear fusion, the answer is maybe. Fusion energy would be safe to human health, environmentally clean, and essentially limitless. But, developing a sustainable fusion reaction still faces significant engineering hurdles and is likely decades away from becoming a reality. So, where are we in the deve…
 
Despite being a reliable, zero-emissions alternative to energy derived from fossil fuels, nuclear energy remains mired in controversy. Opponents often cite four reasons not to include nuclear in the portfolio of alternative energy sources that will replace fossil fuels: its cost, what to do with radioactive waste, the increased risk of nuclear weap…
 
Transitioning to a sustainable energy economy will require significant input of investment capital. But how do investors decide which companies and technologies to back as society moves toward a carbon neutral future? Salim Samaha heads energy project investments in the Americas for Global Infrastructure Partners. GIP is a national leader in privat…
 
Trees are an incredible resource for mitigating climate change, with myriad environmental benefits - not least their ability to remove carbon dioxide from the atmosphere and store it for hundreds to thousands of years. Reforestation - the process of replanting trees in depleted areas - should be included in the array of climate solutions, but it is…
 
China currently produces more greenhouse gas emissions than the next three biggest emitters - the United States, European Union, and India - combined, making a commitment from China to decarbonize its economy essential to reaching global carbon neutrality. But given China is the manufacturing epicenter of the world, the path to decarbonization is n…
 
How do we reach global net-zero emissions by 2050, when there is almost no chance of completely ending our dependence on fossil fuels by that time? The solution will require Carbon Dioxide Removal (CDR) – a host of natural and technological techniques for drawing CO2 out of the atmosphere, effectively producing ‘negative emissions’. We spoke with D…
 
In order to limit global warming to 1.5 degrees Celsius, we must (in addition to reducing emissions) capture carbon and permanently store it where it cannot be released, a process known as carbon sequestration. So, what is currently being done to advance carbon sequestration? What policy and economic levers need to be implemented to incentivize its…
 
What incentives are needed for airlines to adopt sustainable aviation fuel (#SAF) and decarbonize air travel? How does SAF get tested and approved for use in commercial aviation? Who are the players in this space now and how much SAF is already being used? Steve Csonka joins Climate Now to discuss this important new technology. Steve Csonka is the …
 
As the climate crisis worsens, more and more companies are committing to go "net-zero". Most of these commitments include the purchase of carbon offsets or investment in negative emissions projects, designed to offset the emissions resulting from companies' operations. The carbon offset market is in high demand due to this surge of net-zero pledges…
 
Declining renewable energy costs have sparked a renewed interest in green hydrogen, which has the potential to decarbonize sectors that are harder to electrify. Because hydrogen doesn't occur by itself on Earth, it must be separated from other elements, such as oxygen in water. Electrolysis is the process of using electricity from renewable energy …
 
How exactly are plants converted into liquid transportation fuel? And what obstacles does bioenergy need to overcome in order to displace fossil fuels in the US energy economy and abroad? Jerry Tuskan is the CEO of the Center for Bioenergy Innovation and Group Lead for Plant Systems Biology in the Biosciences Division at Oak Ridge National Laborato…
 
Bioenergy is a renewable energy for its carbon neutrality - plants absorb CO2 during photosynthesis and emit the same amount when combusted for energy. But to significantly reduce our reliance on fossil fuels, substantial amounts of biomass, or organic matter, are required. What types of biomass can sustainably and economically be used for energy? …
