Burning fossil fuels is causing nearly one in five of all deaths worldwide.
A new study found the death toll is almost twice as high as previously thought.
China’s clean-air initiatives have saved 1.5 million lives, but the country still has the highest death toll.
The researchers call on policymakers to make the switch to clean energy.

Fossil fuel pollution was responsible for almost one in five deaths in 2018, according to a new study which has prompted calls for governments and businesses to do more to switch to clean energy.

More than eight million people died as a result of breathing in minute particulate matter from burning fossil fuels in 2018, according to research from Harvard University, in collaboration with the University of Birmingham, the University of Leicester and University College London.

They found that particulate pollution was responsible for 18% of deaths in 2018, almost twice the level previously estimated. In 2016, the World Health Organization (WHO) put the global death toll from air pollution at 4.2 million.

We already know that more than nine out of 10 people live in areas where air pollution exceeds WHO safety levels. So how did the researchers arrive at such alarming figures for fossil fuel-related deaths?

The study took a new approach, using a 3D atmospheric modelling tool to pinpoint the greatest concentrations of fine particulate (PM2.5) pollution around the world, and combined that data with more accurate measurements of its effects.

Death toll underestimated

As well as confirming that regions with the worst air pollution have the highest rates of mortality, the study, published in the journal Environmental Research, found that the number of deaths in these regions had been underestimated.

Although China has achieved a dramatic reduction in particulate pollution – numbers almost halved between 2012 and 2018 – the country still emerged with the highest death toll (3.9 million) followed by India (2.5 million).

The study found that without its clean air initiatives, the death toll in China would have been even higher. As well as saving 1.5 million lives in China, the measures had also reduced deaths from particulate pollution outside the country by almost a million as well.

North America, Europe and Asia were also shown to suffer more deaths from particulates than previously thought. Overall, the study found higher mortality rates among people who suffered long-term exposure to fossil-fuel emissions, even at comparatively low levels.

Switch to clean energy

“Our study adds to the mounting evidence that air pollution from ongoing dependence on fossil fuels is detrimental to global health,” said Professor Eloise Marais of University College, London, one of the report’s authors.

“We can’t in good conscience continue to rely on fossil fuels, when we know that there are such severe effects on health and viable, cleaner alternatives,” she added.

Harvard Professor Joel Schwartz, another of the report’s authors, said that often discussion of the harmful effects of burning fossil fuels focused on CO2 emissions and climate change and overlooked the damage to health from pollutants emitted along with greenhouse gases.

“We hope that by quantifying the health consequences of fossil fuel combustion, we can send a clear message to policymakers and stakeholders of the benefits of a transition to alternative energy sources,” he said.

Global leaders, surveyed for the World Economic Forum’s 2021 Global Risks report, ranked human environmental damage, like air pollution, as one of the top 10 clear and present dangers facing the planet. They also ranked it the third most likely risk to materialize in 2021.

World Makes Haste Too Slowly on Cutting Energy Use

The annual report card on the global energy industry says progress towards lower energy use must be much faster.

The world is dragging its feet on efforts to tackle the climate crisis by reducing its energy use, according to a global watchdog.

In its World Energy Outlook 2020, the lnternational Energy Agency (IEA) says that while emissions of carbon dioxide (CO2, the main climate-changing greenhouse gas), are falling, the reduction needs to be far steeper to make any meaningful impact.

“Despite a record drop in global emissions this year, the world is far from doing enough to put them into decisive decline”, says Fatih Birol, the IEA’s executive director.

The Agency says energy demand is set to drop by 5% in 2020, with an overall decline of 7% in emissions of CO2 from the global energy sector. This means that annual emissions of CO2 are back to where they were a decade ago, the report says.

Oil demand this year is likely to be down by 8%, while coal use will fall by 7%.

Solar projects now offer some of the lowest-cost electricity ever seen.”

That’s the headline good news: the bad news is that emissions of methane – among the most potent of greenhouse gases – are rising, says the report.

Total global investment in the energy sector is also falling dramatically, and is set to be down 18% year on year.

That means that despite the rise of renewable energy, particularly of solar power, governments, utilities and corporations around the world are still not spending enough to bring about a major transition in energy use – and to meet the challenge of catastrophic climate change.

“Only an acceleration in structural changes to the way the world produces and consumes energy can break the emissions trend for good”, says the IEA.

Problem grids

While hydropower is still the leading source of renewable power, solar is described as the new king of electricity.

“With sharp cost reductions over the past decade, solar PV [solar photovoltaic energy] is consistently cheaper than new coal- or gas-fired power plants in most countries, and solar projects now offer some of the lowest-cost electricity ever seen.”

A major problem is that as solar and wind projects are installed and expanded, other parts of the energy sector also need to be developed, particularly infrastructure associated with electricity grids.

In many parts of the world energy utilities are in severe financial straits and have little or no money to maintain or invest in achieving more efficiencies and in infrastructure.

“Electricity grids could prove to be the weak link in the transformation of the power sector, with implications for the reliability and security of electricity supply”, says the IEA.

Covid-19’s effects

The report says it’s not just the energy industry that has to change. “To reach net-zero emissions, governments, energy companies, investors and citizens all need to be on board – and will all have unprecedented contributions to make.”

The Covid crisis is a major factor in assessing the global energy outlook.

The pandemic, says the IEA, has caused more disruption in the energy sector than any other event in recent history, with impacts for years to come.

“It is too soon to say whether today’s crisis represents a setback for efforts to bring about a more secure and sustainable energy system, or a catalyst that accelerates the pace of change”, the report says. —Climate News Network, LONDON, 16 October, 2020

We Can Win the Fight Against Climate Change

The United States can deliver 90 percent clean, carbon-free electricity nationwide by 2035, dependably, at no extra cost to consumers and without the need for new fossil fuel plants, according to 2035 Report: Plummeting Solar, Wind, and Battery Costs Can Accelerate Our Clean Energy Future, a study released in June from the University of California, Berkeley.

The 2035 Report is the first study of its kind to show how recent cost declines for solar, wind, and battery storage allow the U.S. to dramatically reduce generation and emissions from existing fossil power plants while retiring coal and reducing gas generation by 70 percent.

Economic & Job Growth

The rapid buildout of additional renewable energy would inject $1.7 trillion of investment into the economy and increase energy sector jobs by up to 530,000 per year through 2035, across all regions of the U.S., without raising consumer bills.

The 2035 Report’s release is accompanied by a set of policy recommendations to realize the jobs and economic benefits envisioned by the nonpartisan policy firm Energy Innovation. The primary policy recommendation is establishing a technology-neutral national clean energy standard targeting 90 percent by 2035 and 100 percent by 2045. Additional recommendations to unlock a clean energy future include complementary policies that support clean energy deployment, address wholesale market failures, remake utility grid regulation, and ensure an equitable and fair energy transition for impacted communities.

“What an incredible opportunity for economic stimulus. A federal clean energy standard, supported by government investments in deployment and American manufacturing, could put us back on track for a healthier economy. Meanwhile, continued policy leadership from the states can bolster progress.”
―Sonia Aggarwal, Vice President at Energy Innovation

Path to Avoid Worst Climate Change Impacts

The 2035 time frame for near-complete decarbonization of the power sector is significant because it is 15 years earlier than projected in most state and national policy proposals, which provide little hope that the worst climate change impacts can be avoided. In October 2018, the U.N.’s Intergovernmental Panel on Climate Change warned that the world has only a dozen years to halve emissions in order to limit warming to 1.5°C.

“We’re talking about the ability to achieve near-100 percent clean electricity by 2035, in half the time most people are talking about.”
“This is exciting, because the 2035 timeframe is actually compatible with climate realities. However, this outcome isn’t possible without strong policy changes and our hope is this report can help inform the dialogue on federal, state, and corporate policies needed to achieve it.”
―David Wooley, professor at the UC Berkeley Goldman School of Public Policy and Executive Director of the Center for Environmental Public Policy

By 2030, the report finds the U.S. could reach over 70 percent clean electricity, reducing U.S. economy-wide emissions by 18 percent. Up to 85,000 unnecessary premature deaths associated with air pollution from power plants in the U.S. could be avoided through 2050 by reaching a 90 percent carbon-free electric generation sector by 2035, which would reduce economy-wide emissions 27 percent.

Savings & Reduced Damage from Pollution

Delivering 90 percent clean electricity by 2035 also avoids $1.2 trillion in environmental and health costs through 2050 by reducing damages from air pollution and carbon emissions.

The target year of 2035 allows sufficient time for most coal and gas plants to recover their fixed costs, thereby avoiding risk of stranded costs for consumers and investors, if the right policies are in place.

“Cost reductions in clean technology have occurred much faster than anticipated just a few years ago.”
“This is the first report to integrate the latest low prices for renewable energy and storage and shows it is technically and economically feasible to deliver 90 percent carbon-free electricity on the U.S. power grid by 2035.”
―Dr. Amol Phadke, Senior Scientist and affiliate at UC Berkeley’s Center for Environmental Public Policy

New fossil fuel generators are not needed. Wind, solar, and battery storage can provide the bulk of the 90 percent clean electricity. Existing gas plants used infrequently and combined with storage, hydropower, and nuclear power are sufficient to meet demand during periods of extraordinarily low renewable energy generation or exceptionally high electricity demand. Power generation from natural gas plants would drop by 70 percent in 2035 compared to 2019.

The study also finds that robust policy reforms are needed to reduce emissions and increase jobs will not be realized.
