The right to not buy fossil fuels

November 6, 2023 By EarthWise Leave a Comment

Minnesota has been one of the most aggressive states in setting and realizing clean energy goals. As of this year, Minnesota gets 55% of its energy from net zero carbon emission sources. The state has goals of reaching 80% green energy by 2030, 90% by 2035, and 100% by 2040. Recent legislation in Minnesota aims at further reducing carbon emissions and job creation in the clean energy sector.

All of this is very good news, but not for the neighboring state of North Dakota. Minnesota getting all of its energy from clean energy sources means that it would no longer be a customer for the fossil fuel products of North Dakota.

North Dakota is known for its vast reserves of coal, oil, and natural gas and, apart from agriculture, the energy industry is the biggest moneymaker in the state. Faced with the aggressive clean energy initiatives of its next-door neighbor, North Dakota has threatened to sue Minnesota.

What would be the basis of such a lawsuit? The argument would be that Minnesota’s clean energy goals would be in violation of interstate commerce laws and infringe upon North Dakota’s economic sovereignty. The claim would be that the energy regulations in Minnesota unfairly discriminate against North Dakota’s energy products.

Minnesota, on the other hand, would defend its energy goals as a legitimate exercise of its own state sovereignty and a necessary response to the climate crisis.

The outcome of any legal battle that may take place will have far-reaching implications for Minnesota and North Dakota as well as for other states across the country that have clean energy initiatives.

Counting Trees | Earth Wise

April 11, 2023 By EarthWise Leave a Comment

Scientists estimate that there are about 3 trillion trees on the earth. A huge number but probably half as many as there were before people entered the picture. And we’re losing about 10 billion trees a year to toilet paper, timber, farmland expansion, and other human activity. Trees play a crucial role in taking carbon dioxide out of the atmosphere and storing it away. For this reason, trees have become an integral part of the effort to mitigate climate change.

There are major initiatives underway around the world to plant more trees. Part of this is driven by the increasing use of carbon credits by companies trying to offset their carbon emissions. These credits are earned by either planting new trees or paying farmers or other landowners not to cut down existing trees. But how many trees are actually planted and how many survive over time?

Whether these efforts are really resulting in more trees and more carbon storage is not easy to determine. Current international inventories of global tree-sequestered carbon are subject to great uncertainty.

Researchers from the University of Copenhagen and NASA have developed a method for mapping large numbers of trees and determining their carbon content. Using artificial intelligence techniques to analyze ultra-high-resolution satellite images, they can count trees, determine their individual species, and measure their carbon content.

A study of images from Africa’s Sahel region found that it is home to nearly 10 billion trees that are currently storing 840 million tons of carbon.

Now that the groundwork for this new methodology is complete, it is ready to be deployed by public agencies, NGOs, and other interested in monitoring the numbers of trees and their carbon content.

Planting Millions Of Trees Isn’t So Easy | Earth Wise

November 11, 2022 By EarthWise Leave a Comment

There are initiatives around the world to plant millions of trees as a way to fight climate change. Unfortunately, scientists have observed that many of these projects are ill-conceived and poorly managed. Some have failed to grow any forests at all.

One such project was an attempt to plant a million mangrove seedlings in coastal mud on the Filipino island of Luzon in 2012. Ten years later, less than 2% of the trees have survived. The other 98% have died or have washed away. The problem was that the site of the project was ecologically unsuited to mangroves because it is too waterlogged and there is no oxygen available except in a few sheltered spots.

In 2019, the Turkish government managed the planting of 11 million trees in 2,000 sites across the country. A later survey found that 90% had died, although the government denies that assertion.

Many other projects have also had dismal results. The causes of failure vary but include planting single species of trees that become vulnerable to disease, competing demands for land, changing climate, planting in areas not previously forested, and lack of ongoing care for the saplings including watering them.

Nobody is opposed to mass tree planting. There is no anti-tree lobby. But tree planting is sometimes a form of greenwashing. It is great for public relations but unless it is done properly with appropriate planning, it can be a waste of effort and money. The result can be a phantom forest that does nothing for the climate.

Forest planting can work if the social and environmental conditions are right, and if planting is followed by long-term monitoring and care of the trees.

Phasing Out Disposables | Earth Wise

May 5, 2022 By EarthWise Leave a Comment

Humans generate a remarkable amount of garbage. According to the World Bank, humans produce 4.5 trillion pounds of trash every year, with at least 33% of this garbage not managed in an environmentally-safe manner. By 2050, global garbage generation is expected to reach nearly 7.5 trillion pounds a year.

Globally, an average of 1.6 lbs of waste is generated per person per day. While high-income countries only account for 16% of the global population, they are responsible for about 34% of the world’s waste.

But almost everything humans throw away was bought from a company. Whether it was the packaging or the product itself, we purchased it from somewhere. There’s a growing movement to hold the companies responsible for the trash they produce.

Faced with increasing consumer consciousness, many companies are stepping up and announcing initiatives to reduce their waste. Starbucks is one of them. The company’s white logo-emblazoned paper cups and clear plastic cups are instantly recognizable symbols of the brand. But these ubiquitous cups are disposable and also serve as a symbol of our throwaway society.

By the end of next year, Starbucks is planning to allow customers to use their own personal mugs at every location in the U.S. and Canada. By 2025, the company wants every customer to be able to use either their own mug or to borrow a ceramic or reusable to-go mug. This borrow-a-mug program is currently being tested in eight different markets around the globe.

In lieu of regulation mandating corporate responsibility for waste, we will have to hope that more companies do the right thing.

Electric Cars Are Coming Sooner Than Expected | Earth Wise

September 30, 2021 By EarthWise Leave a Comment

It is widely believed that electrification is the future for vehicles. The only question is how long the transition will take. Predictions are all over the map, but the recent trend is to revise those predictions to say it will happen sooner than previously thought.

A recent report from the international accounting firm Ernst & Young predicts that EV sales in the US, China, and Europe will surpass those of fossil-fuel-powered vehicles five years sooner than previously expected. The report forecasts that fossil-fueled vehicles will represent less than 1% of global sales by 2045, taking their place among other historical but essentially abandoned technologies.

Europe is expected to be the leader in EV adoption. The forecast is that EVs will surpass legacy vehicles by 2028. China is expected to follow by 2033. The US is lagging behind, but even here, electrics are expected to achieve a majority of car sales by 2036.

Plug-in vehicle sales have surpassed a 10% market share in California and Tesla now has a 1.7% share of the total US car market. Norway is the global EV leader with 3 out of 4 car buyers choosing electrics. In that country, Tesla’s Model 3 is the top-selling vehicle of any kind. In Switzerland, 40% of car sales are EVs or hybrids.

There are many variables that will affect the timetable for the EV transition. Among them are the timetable for widespread use of autonomous vehicle technology, the effects of policy initiatives by governments around the world, the development of charging infrastructure, and the evolution of electricity generation and energy storage.

In any case, looking at the product roadmap for virtually every automobile manufacturer makes it clear that electric cars are the future.

Utility-Scale Solar In Upstate New York | Earth Wise

June 22, 2021 By EarthWise 2 Comments

The first operational utility-scale solar projects in upstate New York are expected to commence commercial operations by the end of this year. A portfolio of eight projects comprising over 200 megawatts of generating capacity is being developed by CS Energy in partnership with Goldman Sachs Renewable Power Group and NYSERDA.

The projects include three 27-megawatt installations in the Capital Region – in Easton and Stillwater, three 27-megawatt installations in the Mohawk Valley – in Mohawk and Pattersonville, and two 27-megawatt installations in the Southern Tier – in Willet and Greene.

The projects will support more than 500 jobs and represent more than $160 million of private investment that is expected to generate over $80 million in benefits to local communities and regions. Those benefits will come to local landowners, property tax jurisdictions, and to local contractors who will provide ongoing operations and maintenance support for the projects.

The projects are the result of New York’s Clean Energy Standard, established in 2016 as well as 2019’s Climate Leadership and Community Protection Act. These initiatives made commitments that 70% of the electricity consumed in New York would be generated by renewable energy sources by 2030.

CS Energy has built over 150 megawatts of solar projects in New York to date. By the end of this year, that number will be close to 500 megawatts. CS Energy recently opened a regional headquarters in Albany to further support the company’s growth. The Goldman Sachs Renewable Power Group owns and operates more than 2.3 gigawatts of clean power across the country.

30 Million Solar Homes | Earth Wise

March 29, 2021 By EarthWise Leave a Comment

A national coalition made up of more than 230 organizations has launched an initiative called the 30 Million Solar Homes campaign. The goal is to add enough rooftop and community solar energy to power 30 million homes across the U.S. over the next five years. That would be the equivalent of one in four American households.

The major focus of the 30 Million Solar Homes initiative is to rapidly and massively scale programs that help low-income families benefit from solar power. The coalition lists 15 federal policy initiatives including making solar tax incentives more equitable, providing more reliable low-income energy assistance through solar energy, supplementing low-income weatherization assistance with solar energy, and specifically funding solar projects in marginalized communities.

The federal government spends billions of dollars every year to help families to pay their energy costs, but these efforts only serve less than a fifth of the eligible population. Funding rooftop and community solar access for these households would provide long-term financial relief and reduce the need for annual energy bill assistance.

The more than 230 organizations in the coalition represent organizations focused on energy equity, climate, business, environment, faith, and public health. The coalition estimates that executing the plan would create three million good-paying jobs, lower energy bills by at least $20 billion a year, and reduce total annual greenhouse gas emissions by 1.5%.

Over the coming months, the campaign will seek to educate lawmakers and the Biden-Harris Administration about the benefits of distributed solar energy. The vision outlined by the coalition is an ambitious one to say the least.

Planting Trees and Climate Change | Earth Wise

June 1, 2020 By EarthWise Leave a Comment

Forests are among the most important natural carbon sinks. Trees remove carbon from the air and store it in their trunks, branches, and leaves, and transfer part of it into the soil. But in some regions, these natural carbon sinks are starting to weaken due to deforestation, forest degradation, and the impacts of climate change. This problem has led some climate mitigation projects to focus on increasing the overall number of trees on the planet.

But, according to a paper recently published in the journal Science, “we can’t plant our way out of climate change.” That’s the simple message from Restoration Ecologist Karen Holl and University of São Paulo Professor Pedro Brancalion to anyone who thinks planting one trillion trees will reverse the effects of climate change. They say planting more trees is only one piece of the puzzle. Any initiatives like 1t.org or the Trillion Tree Campaign must be done carefully and be accompanied by commitments to long-term management.

Tree plantings can provide many environmental benefits, including improving water quality, biodiversity, and increasing shade. But trees can sometimes have undesirable impacts, such as harming native species and ecosystems or reducing water availability, depending on where and how the trees are planted.

The authors suggest four principles that should guide forest enhancement initiatives: reduce forest clearing and degradation, balance ecological and social goals, view tree plantings as one part of a multifaceted solution, and plan, coordinate and monitor the work.

While tree plantings can clearly be part of the solution, slowing the pace of climate change requires a comprehensive approach that must start with burning less fossil fuels.

The Value Of Abandoned Agricultural Lands | Earth Wise

February 18, 2020 By EarthWise Leave a Comment

It is perhaps surprising to learn that more land is now being abandoned by farming than converted to it. In fact, abandonment of rural lands has become one of the most dramatic planet-wide changes of the modern era, affecting millions of square miles of land.

In part, it is due to rural flight driven by the economic, social, and educational appeal of cities. It is also a result of climate change and the globalization of the food supply chain. The global footprint of agriculture has been decreasing over the past twenty years but the global food supply isn’t shrinking. The lost land has generally been marginal and farming elsewhere has become more productive.

Many researchers see abandoned agricultural lands as a huge opportunity for ecological restoration and strengthening of biodiversity. Others see these lands as an opportunity for a massive program to plant trees to reduce carbon dioxide in the atmosphere. A recent study published in Science estimated that planting trees on abandoned agricultural lands could remove 25% of the carbon dioxide humans have added to the atmosphere.

There are strong criticisms to all of these ideas. In most cases, the studies don’t incorporate the social context of why these lands are in transition, the potential effects on local populations, whether the lands are publicly or privately owned, and whether lands now suitable for regeneration will remain so as climate change advances.

Current government initiatives on degraded lands typically lack even rudimentary planning. There are real opportunities presented by the vast amounts of abandoned agricultural lands, but there are many caveats and many issues to confront. As a society, we have barely begun to even think about what to do.

The Benefits Of Zero-Carbon Cities

November 8, 2019 By EarthWise Leave a Comment

A new report issued by a coalition of 50 leading international institutions shows that low carbon initiatives in cities could reduce urban emissions by nearly 90% and support 87 million jobs worldwide by 2030. The report finds that implementing low carbon measures in cities would be worth almost $24 trillion by 2050.

Cities are home to more than half the world’s population but produce 80% of gross domestic product and 75% of carbon emissions. The research highlights the significant benefits carbon reduction can bring to cities in areas such as public health, job creation, and poverty alleviation.

The report shows that it is possible to cut 90% of emissions from cities using currently available technologies and practices including carbon savings from buildings, transportation, materials efficiency, and waste reduction. Doing so would require an investment of nearly $2 trillion per year but would generate annual returns of nearly $3 trillion in 2030 and $7 trillion in 2050 based on cost savings alone. Many low carbon measures would pay for themselves in less than five years, including more efficient lighting, electric vehicles, improved freight logistics, and solid waste management.

In addition to economic benefits, compact, connected and clean cities could provide a higher standard of living and greater opportunity for all. These measures would also reduce air pollution, cut chronic traffic congestion, and improve worker productivity.

The report offers case studies from around the world where national and local governments have worked together to rapidly and profoundly transform their cities for the better within 20 or 30 years.

Hydrogen Progress

April 18, 2018 By EarthWise Leave a Comment

As low-cost solar and wind energy become increasingly pervasive, the prospects for hydrogen-based transportation systems are improving. The reason is that cheap electricity makes it practical to produce hydrogen by breaking down water rather than getting it from reforming natural gas, which results in carbon dioxide emissions. The real goal is for hydrogen to be a renewable and carbon-free fuel.
