As 2020 approaches, the climate action spotlight is on forests

With 2020 fast approaching, countries, companies, and other stakeholders are taking stock of their climate commitments. As they consider ways to meet and enhance climate goals, interest in net zero emissions commitments and carbon removal technologies has grown. But what these discussions reveal is that forests are crucial. Capable of significantly reducing net emissions at a low marginal cost, and in the short-term, forests are an important piece of the climate change mitigation puzzle.

This year, tropical forests have dominated the spotlight. The forest fires raging throughout Brazil, Bolivia, and Indonesia are part of a disturbing trend: despite commitments from governments and companies, deforestation is still on the rise globally. Key forest ecosystems such as the Amazon continue to face the pressures of crop expansion for agricultural production, illegal extractive activities like timber harvesting and mining, relaxed legal enforcement and weakened environmental policies.

As deforestation persists, the planet’s capacity to absorb carbon pollution diminishes and more carbon is being released; tree cover loss in tropical forests accounts for about 16 to 33 percent of global emissions. We should be alarmed. But we should also be hopeful. Here are a few reasons why:

Four takeaways on climate change and sea level rise in the latest IPCC report

The Intergovernmental Panel on Climate Change has published yet another alarming report about the dangers we face from the climate crisis.

The Special Report on the Ocean and Cryosphere in a Changing Climate synthesizes the latest science on how the oceans and frozen parts of the world have changed, and will continue to change, because of global warming.

More than 100 scientists from 36 countries summarized findings from almost 7,000 peer reviewed research studies. The authors addressed over 30,000 comments from expert reviewers and governments in 80 countries.

A major focus of the report is sea level rise, a climate change impact that is especially serious to those who live in coastal regions – which is more than a quarter of the world’s population. Recent advances in science, such as higher quality data, improved physical understanding, and agreements across modeling studies have improved understanding of the threat of sea level rise.

Here are four of the report’s most important takeaways on sea level rise:

The Getting to Zero Coalition: a step further towards decarbonization

This post was authored by Aoife O’Leary, Natacha Crete and Marie Hubatova from Environmental Defense Fund Europe

Today at the United Nations Climate Action Summit, the youth movement with Greta Thunberg at its helm, called out the world leaders in attendance for a lack of action in the climate emergency. Greta’s impassioned plea again makes clear that the time for action is now. Action from all sectors. In the absence of real transformative action, we have no hope of meeting the temperature goals established by science and enshrined in the Paris agreement.

The UN Secretary General Antonio Guterres convened the climate action summit asking that countries and sectors come forward with scalable action. The summit is supposed to clarify the “how” in our path to avoiding catastrophic climate change. These provide the necessary catalyst for countries to take more ambitious commitments at the international climate negotiations in Glasgow in 2020. While much of what was announced today at the summit was pretty underwhelming, major players in the shipping sector have made significant effort to answer Guterres’ call.

Trump’s ACE Rule May Especially Harm Vulnerable Communities

(This post was co-authored by EDF intern Laura Supple)

The Trump administration’s latest attack on clean air protections may cause the greatest harm to the most vulnerable communities – according to EPA’s own projections.

In June, the Trump administration repealed the Clean Power Plan – America’s first and only nationwide limit on carbon pollution from existing power plants – and replaced it with a pollution-enabling rule that, by EPA’s own numbers, would increase climate pollution in many states compared to no policy at all.

Experts have warned that under the Trump replacement, called the ACE rule, many parts of the country would also see increases in health-harming sulfur dioxide and nitrogen oxides pollution that lead to soot and smog. While the Administration has tried to downplay the public health consequences of the new rule, EPA’s projections show that vulnerable communities around the nation will likely suffer the most from these dangerous pollution increases.

Summer smog review: new analysis shows continued challenges to air quality

(This post was co-authored by EDF intern Jayne Stevenson)

Summer brings sunshine, fun, and outdoor adventures – but unfortunately, it also brings smog that causes serious health problems for many American families.

We have made significant progress delivering healthier summer air, but many families still find themselves sidelined by ground-level ozone pollution – commonly called smog. That pollution will be made even worse by climate change.

New EDF analysis shows that so far in 2019 we’ve seen more than 2,500 smog exceedances – meaning ground-level ozone pollution monitoring stations recorded levels higher than allowed under the 2015 National Ambient Air Quality Standards for Ozone. (That limit is a maximum eight-hour concentration greater than 70 parts per billion).

Approximately 185 million people across America were exposed to at least one of those exceedances, which spanned 248 counties in 40 states and the District of Columbia.

By the numbers: Colorado Zero Emission Vehicle Program will cut climate pollution and save Coloradans money

(This post was written by EDF  Attorney Laura Shields) 

The numbers are in for Colorado’s proposed Zero Emission Vehicle (ZEV) program – it will cut climate pollution and save Coloradans millions of dollars.

This week, the Colorado Air Quality Control Commission is formally considering adoption of the ZEV program for model year 2023 through 2025 vehicles. (Colorado already adopted state Low Emission Vehicle standards last year).

What’s at stake for Coloradans?

This important clean air program means that, while no Coloradan has any obligation to buy or choose a zero-polluting vehicle, ALL Coloradans will have more models of zero-emitting vehicles to choose from if they want a cleaner car.

These clean vehicles will save Coloradans hard-earned money at the gas pump and will reduce dangerous climate pollution. They will also help reduce smog-forming pollution in all communities across Colorado, clean up Denver’s brown cloud, and lift the veil of haze pollution in our world-class national parks and wilderness areas.

In short, Colorado’s proposed ZEV program will mean healthier air, fuel cost savings, more vehicle choice and a safer climate for all Coloradans.
