Low carbon fuel standards: what, why, and how?
On February 15, 2023, the U.S. Senate held a hearing considering a national clean fuels program, modeled after California’s state-wide Low-Carbon Fuel Standard (LCFS). The LCFS sets an annually decreasing standard of net carbon intensity (amount CO2 emission

The road to decarbonized trucking
2022 potentially marked a turning point for the U.S. electric vehicle (EV) market, with new EV car sales increasing by 65% over 2021 sales, and now accounting for nearly 6% of all new vehicle sales. (If EVs maintained a 65% annual growth rate, they would reach

Updates to the GHG protocol: Scope 1, 2, 3 and more?
More than one third of the world’s 2,000 largest publicly traded companies have made some kind of net-zero commitment, and the list is growing quickly. A critical part of those corporate plans will be securing cleanly sourced electricity for their energy nee

Decarbonizing diesel: cleaner fuels and engines
Electrification is going a long way in decarbonizing small vehicles (like passenger cars) in the global transportation sector, which produces about 16% of global emissions. But for long-haul transportation: trucking, shipping and the aviation industries, elect

How to decarbonize a city
In November 2021, the City of Ithaca announced the approval of a plan to decarbonize all of its buildings by 2030. In this first-of-its-kind decarbonization plan, Ithaca outlined a pathway to electrify roughly 6,000 homes and buildings as a first step to enact

Bill McKibben’s take on building a successful climate movement
On April 22, 1970, 20 million people across the U.S. marched, attended speeches and sat in teach-ins, marking the first Earth Day, and spurring on the enactment of the Clean Air Act, the Clean Water Act and the founding of the EPA, all of which occurred later

How to fix the clean energy bottleneck
In 2021, U.S. President Biden signed an executive order with the directive to achieve 100% carbon-pollution free electricity in the United States by 2030. The goal is certainly achievable: currently wind and solar are the cheapest forms of electricity generati

Farm to stable CO2 storage
The agricultural sector produces about a tenth of the world’s greenhouse gas emissions, and while most of that comes from livestock (about 2/3), emissions from crop production still total about 2.2 billion metric tons of CO2-equivalent. Interestingly, we onl

Inside the DOE: Understanding the role of the US Department of Energy in the energy transition
“We’ve built an entire industrial economy around a set of energy sources, and we’re now thinking about diversifying way beyond that. And that’s a big set of changes.” What will it take to diversify our energy economy, and how do we actual

Breaking the link between how much we consume and economic growth
The carbon footprint of stuff For the last two centuries, continuous economic growth (the increase in the quantity and quality of the economic goods and services that a society produces, per capita) has been recognized as the critical driver in the drastic

A star in the west was brightly shining…
Last week, LLNL’s National Ignition Facility successfully ‘ignited’ a nuclear fusion reaction equivalent to what takes place in the sun: the conversion of hydrogen to helium + energy. In a first, the experiment produced more energy than was

What lies beneath? Efficient heating and cooling.
Can Earth’s geothermal heat warm – and cool – your home? The hottest day ever recorded on Earth was on July 10, 1913. Thermometers in California’s Death Valley measured 134 degrees F. The coldest day ever recorded on land (not on an Antarctic i

The role of microgrids in the energy transition
A micro-grid is a local grid. That means that energy generation occurs locally (no giant transmission lines) to support local energy demand, and it has the option to operate independently from a traditional regional power grid. These kinds of grids are attract

Battery power: the future of grid-scale energy storage
Renewable energy sources – wind and solar – have become the cheapest and fastest growing form of electricity generation. But the industry has not yet escaped the perennial criticism that keeps many from believing that the world could run entirely o

What is the future of carbon capture technology?
Since its founding in 1952, the mission of Lawrence Livermore National Laboratory (LLNL) has been to meet urgent national security needs through scientific and technological innovation. Expanding from its focus on nuclear weapons science at the height of the C

The financial value of healthy ecosystems
How many crises can we address at once? In October of this year, headlines broke that the global animal population in 2018 is 69% smaller than it was a half century ago, in 1970. It is the latest bad news in a string of studies on biodiversity loss, which is

Making buildings smarter, greener and healthier
The side benefit of reducing building emissions? Increasing quality of life. Building operations (heating, cooling and electrification) account for 27% of global CO2 emissions, but represent some of the lowest-hanging fruit in the challenge of global decarbon

Making waves with marine carbon capture
The global shipping industry emits ~1 billion tonnes of carbon dioxide annually, about as much as the sixth highest emitting nation in the world. In hopes of changing course, the International Maritime Organization (IMO) has mandated that starting in 2023, mos

An electrifying look at the future of steel
For some sectors of our economy, electrification as a decarbonization strategy is a whole lot easier said than done. Take the steel industry – which is responsible for 11% of global CO2 emissions. A large part of those emissions come from the ‘coking

The solarcoaster: adoption curves and business models
Mitigating climate change is a race against time, requiring “rapid, far reaching and unprecedented changes in all aspects of society,” according to the IPCC, who says we need to halve global emissions by 2030. But Tom Dinwoodie of Epic Institute argues tha
