Getting on track with home decarbonization
The Biden Administration in the U.S. has set a goal of achieving a net-zero emissions economy by 2050, which among other things means that U.S. households, and the appliances and machines that run within them, will need to be powered almost entirely by carbon-

In the Navy! There is a climate action plan
In 2003, the U.S. Department of Defense released a report entitled, “An abrupt climate change scenario and its implications for United States national security,” which “imagined the unthinkable” – that gradual global warming could lead to relatively

Less waste, more energy
Landfills emit about 2% of the world’s greenhouse gases, but in terms of lowering global emissions, they represent some of the lowest hanging fruit. When organic waste – like municipal food waste, agricultural waste, and forest residue – is disposed

This Week in Climate News: Fires, national EV charging standards, and the global stocktake
This Week in Climate News: One of the greatest difficulties in addressing climate change has been how invisible the crisis was. You cannot see the 40 billion metric tons of CO2 being added to the atmosphere each year, or necessarily feel that average global

What could climate instability mean to you?
Since humans began settling down and building civilizations 10,000 years ago, the Earth’s climate has been relatively stable. But before that, the climate was more unstable – unpredictable – and humans were nomads, forced to follow the good c

Episode 100: How to talk about climate change
A 2022 study by Yale University found that two thirds of Americans (67%) rarely or never talk about climate change, and rarely or never hear people they know talking about it either. Despite the existential threat that it poses, one third of Americans (32%)

The evidence for peak fossil electricity
In 1909, headlines declared the U.S. would run out of petroleum by 1940. In 1945, the estimate was that the U.S. had 13 more years of petroleum reserves left. In 1966, we only had 10 more years before the “figurative dipstick in the United States’ oil sup

Fixing the problems with ESG investing
According to a 2022 poll from the Associated Press, although 93% of Americans acknowledge that human activity impacts climate, nearly half of Americans (47%) feel that their actions don’t have an impact on climate change. And yet, we know – it is the colle

What will happen when the permafrost thaws?
Since the Industrial Revolution nearly 150 years ago, global average temperatures have increased by more than 1 degree C (1.9 degrees F), with the majority of that warming occurring since 1975. But during these recent decades of accelerated warming, temperatur

LEED certifying buildings and cities, and why it matters
The built environment represents one of society’s largest environmental impacts – contributing nearly one fifth of global GHG emissions, not to mention impacts on natural resources like air and water quality, local ecosystems, and quality of life fo

The debate about nuclear’s role in the clean energy transition
Every approach to decarbonizing the energy sector comes with its share of costs and benefits: renewables are cheap and clean, but require enormous amounts of land and are not always available when power is needed. Batteries provide useful back up power, but ad

What is the future of agriculture in California?
On March 30, 2023, in partnership with the Livermore Lab Foundation and The Maddy Institute, Climate Now hosted a one day summit in Fresno, CA, examining the intersection of climate change and agriculture. Agriculture is both a leading driver of greenhouse gas

Making hydrogen and carbon black out of renewable natural gas
Renewable natural gas (RNG), made from the decomposition of organic waste like livestock manure, is not necessarily net-zero if it’s burned to run a turbine or drive a car. But what if the RNG is not burned, but is rather pyrolyzed, breaking it down in

Minerals discovery and mining for the energy transition
As we transition to a clean energy economy, demand for minerals like copper, cobalt, nickel, and lithium is projected to skyrocket. According to a 2022 report from the International Energy Agency, the total mineral demand from clean energy technologies will

Decarbonizing a city with heat pumps and thermal energy networks
For a building owner, building decarbonization has myriad benefits: lower utility bills, lower maintenance, healthier and more comfortable living. But the barriers to reaching those benefits are large, particularly the high upfront costs and complicated renova

Net-zero cities: Making decarbonization work for everyone
Reducing average global temperatures. Preserving biodiversity. Decreasing the risk of droughts, floods and hurricanes. Reducing air pollution. Reducing utility bills. Creating new jobs and opportunities. Building community engagement. Fostering environmental e

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
