For a Clean, Safe Ride to School, Electric Buses Get Straight A’s. Propane? Needs Improvement

School districts around the country are considering a switch to buses that use less fuel, cost less, and, most importantly, provide safe and healthy trips to and from school. Only one option wins on each of these critical criteria: electric. They eliminate the dirty tailpipe emissions of diesel and other fossil fuel models that harm vulnerable lungs, they save money on fuel and maintenance costs and they can even increase the resilience of the local electric grid.

This clear choice is why the majority of the EPA’s Clean School Bus rebate program applications were for —and nearly 100% of the first round of funding went to — electric buses.

But old technology habits die hard, and propane bus manufacturers have allied with propane lobbyists to push school districts to consider their internal combustion buses. And they’re using some of the fossil fuel industry’s old bag of tricks to take on their electric rivals.

Unfortunately, the truth is not on their side and propane does not come out on top.

One year later, taking stock of state “action plans” on clean trucks, buses

Bus that runs on clean energy

It’s been exactly one year since nearly two dozen U.S. and Canadian states signed onto a roadmap to 100% zero-emission truck sales by 2050. While this was an important milestone, it was only intended to be the starting point. States were encouraged to build on these plans by developing localized versions that would meet their own unique needs. It’s part of an MOU – the largest multi-state action on clean transportation in U.S. history — that 19 states comprising a third of the medium- and heavy-duty market signed on to back in 2020.

So, how are these state plans coming along? While many states have taken discrete steps to advance zero-emission truck and buses, most states that adopted the model action plan last year have not taken steps to develop their own blueprints for a zero-tailpipe future.

New research reaffirms hydrogen’s impact on the climate, provides consensus

By Ilissa Ocko and Steven Hamburg

Hydrogen emissions from leakage, venting and purging leads to global warming, new research confirms. To take advantage of the potential benefits of switching from fossil fuel systems to hydrogen, we need to keep emissions at a minimum, and doing so will depend on the development of new instruments that can detect even small leaks, allowing us to minimize them in the future.

A new paper published this summer in the journal Communications Earth and Environment uses five different climate models that show consistent results on hydrogen’s global warming potential at the 20, 100, and 500 year ranges. These results align with other recent studies.

Analysis: Cutting oil and gas methane is one of Canada’s most affordable climate solutions

By Ari Pottens and Maureen Lackner

New research confirms that cutting methane emissions from the oil and gas sector is one of the fastest and most affordable steps Canada can take to help address the climate crisis. According to the report by Dunsky Energy + Climate Advisors, Canada’s upstream oil and gas companies can eliminate 75% of their methane emissions at an average cost of about $11 per tonne. 

Marginal Cost & Potential of Methane Abatement Measures at Gas Sites

This is one of the biggest bargains that exists when it comes to climate solutions. For example, were oil and gas companies subject to Canada’s entire carbon price, they would need to pay $65 per tonne of carbon pollution they create. By 2030, this figure will rise to $170 per tonne. Meanwhile, technologies that can directly capture carbon dioxide from the atmosphere are estimated to cost between $125 and $335 USD per tonne, an astronomical figure compared to methane abatement.  Read More »

New health study shows cost of oil and gas pollution in Appalachia

By John Rutecki

Earlier this summer, EDF, Boston University School of Public Health, the University of North Carolina at Chapel Hill’s Institute for the Environment  and PSE Healthy Energy published a peer-reviewed study that quantified the health impacts of oil and gas pollution, both in dollar value and human lives. The study found that in 2016 alone, pollution from oil and gas production caused $77 billion in health damages across the U.S and thousands of early deaths. Appalachian states had some of the highest health damage rates, especially on a per capita basis. Across Pennsylvania, Ohio and West Virginia there were over 1,000 deaths from oil and gas pollution, with some of the highest rates of childhood asthma exacerbations in the country.

Without action, unreported methane pollution from Saskatchewan could threaten Canada’s climate goals and create more fallout from climate change

Burning trees in a forest

By Ari Pottens and Scott Seymour

It’s no secret that the rampant, out-of-control wildfires which are devastating parts of Canada and creating toxic air quality conditions for millions of people, are exacerbated by climate change. This makes it all the more crucial to rapidly reduce the greenhouse gases behind the climate crisis.

In 2020, Canada’s federal government implemented new regulations to stem the methane emitted from the oil and gas industry — the leading source of methane in the country. The  protections were intended to help cut emissions by 40% – 45% by 2025. Subsequently, the federal government significantly increased its methane ambition and set a 75% reduction goal by 2030.

But a new study is revealing some problems with the way Saskatchewan is managing emissions from a very specific type of oil production known as Cold Heavy Oil Production with Sand. It just so happens that a lot of gas, most of which is methane,  also comes out during this process. Read More »
