This week has carried tough blows for the environment, in the form of a White House budget proposal that would slash funding for a variety of climate, energy and environment-related federal programs. But at least one positive bit of news has also surfaced.
A new report from the International Energy Administration has found that global carbon emissions remained flat for the third year in a row, even while the global economy continued to grow. And while it may still be too early to tell whether emissions are peaking for good now, or whether they will resume increasing in years to come, the findings reinforce the growing sense that it’s now possible to enjoy economic growth without an increase in carbon dioxide output.
According to the report, carbon emissions from the energy sector topped out at about 32.1 billion tons last year, about the same as in 2015 and 2014. On the other hand, the global economy grew by another 3.1 percent, as it has also done over the past few years. These findings also were projected late last year by a group of scientists known as the Global Carbon Project, and are now confirmed by the IEA.
This is good news for global climate efforts. Until now, economic growth has largely been coupled with an increase in industrial activity and energy intensity and its associated greenhouse gas emissions. But the report suggests that the planet may be starting to break this cycle.
The flatline in global emissions is essentially the product of increases in carbon output in some countries and decreases in others. The report notes that China and the United States — the world’s top two largest greenhouse gas emitters — both saw a drop in their carbon dioxide emissions. In the United States, emissions fell by 3 percent and the economy grew by 1.6 percent, while in China, emissions fell by 1.6 percent and the economy grew by a whopping 6.7 percent.
Additionally, emissions in Europe — another top global emitter — remained flat. Together, these developments were able to offset increases in emissions throughout much of the rest of the world. The continued expansion of natural gas and renewable energy and the decline of coal are likely largely to thank in these cases. The report notes that renewable energy sources accounted for half of all global electricity demand growth in 2016.
While this is all good news for the climate, though, it’s still a baby step in the grand scheme of things. It’s important to note that flat emissions don’t mean no emissions — billions of tons of greenhouse gases still went into the atmosphere in 2016 and are on track to continue in that trend for years to come. As long as carbon is still emitted, the planet will continue to warm.
In fact, another recent report from the National Oceanic and Atmospheric Administration found that carbon dioxide concentrations in the atmosphere are rising at the fastest rate ever recorded. That’s despite the recent flatline in global emissions.
Participants in the Paris Agreement are still working to keep global warming within a maximum of 2 degrees of their preindustrial levels — but the clock is ticking. The planet can only afford to emit about 800 billion more tons of carbon dioxide if we want to have at least a two-thirds chance of meeting that goal.
