2018 is the year for rescuing the planet from climate change

This will be a big year for the Paris climate agreement. The broad outlines of the deal were figured out in 2015, but the specific rules governing what it requires countries to do will have to be written by the end of 2018.

In spite of U.S. President Donald Trump’s decision to withdraw the United States from the accord, the deal appears surprisingly strong. In the final months of 2017, Nicaragua and Syria, the last two holdouts of the more than 190 nations that met in Paris, signed on. The U.S., meanwhile, will not be able to withdraw from the agreement until Nov. 4, 2020 — four years to the day after the agreement went into effect and, coincidentally, one day after the next U.S. presidential election.

Now it’s time to figure out the fine print. The process that must wrap up before the end of 2018 is comparable to the period after Congress passes any legislation, when regulatory agencies need to figure out what a given law will mean in practice. Over the course of 2018, negotiators from around the world will be working through the U.N. Framework Convention on Climate Change, the treaty that undergirds the Paris agreement, to do something similar.

At the top of their to-do list are rules for what the U.N. calls “transparency” — that is, rules for measuring countries’ emissions and for measuring their progress toward reducing that pollution.

When each country signed on to the agreement, it offered a goal, or a “national determined contribution,” stating how much it planned to reduce its greenhouse gas emissions. Over time, countries are expected to improve on those pledges. The Paris agreement’s objective is that these goals will gradually add up to a large enough reduction in global emissions that global warming can be contained within 2 degrees Celsius.

Transparency is essential to determine whether that 2-degree target is realistic. Practically speaking, the U.N. needs to figure out how countries will report their progress toward their emission-cutting goals. It will also need to figure out how to determine whether those reports are accurate. This will mean digging into topics that, during past rounds of negotiations, have proven to be complex and technically intricate.

When it comes to reporting, “the Paris agreement itself essentially points to a common approach for countries but also acknowledges a need for flexibility for the countries that need it,” says David Waskow, head of the Washington-based World Resources Institute’s International Climate Initiative. That “common approach” is key, and something that U.S. diplomats representing both Republican and Democratic administrations have pushed for years. If the U.N. has different standards for different countries — for instance, if it holds India and China to lower transparency standards than the European Union — then the agreement will be weakened at a time when it needs to get much stronger.

The flip side of those common reporting standards is flexibility. By allowing for some variation in the information that countries report, the U.N. acknowledges that not every country will be able to measure their greenhouse gas emissions with the same degree of accuracy.

A national government, Waskow explains, needs “to know basic data about not only power plants but industrial facilities, what’s happening with transportation systems and vehicles, what kind of fuels are being used, what’s happening in the agriculture sector, what’s happening with land use, etc. It requires government capacity not only at the national level but at the sub-national level — the city and state and provincial level — to be able to know what power plants and industrial facilities are in operation and at what level they’re producing and emitting.”

Not every county has that capacity. The specifics of how the U.N. deals with the range of data available is one of the things that must be figured out in 2018.

One of the goals of the Paris agreement is that every country eventually will be able to report information with the same degree of accuracy. Initially, however, that won’t be the case. So negotiators this year will have to write rules that require strong and accurate reports but which leave developing countries some wiggle room.

Negotiators will also have to figure out how the U.N. will measure emissions outside national borders, including those from airplanes and boats in international waters. Planes and boats together account for about 4 percent of global emissions, by some estimates, and both air travel and maritime cargo shipping are expected to increase in coming years. Measuring these emissions will likely involve greater use of technology, especially satellites that can measure carbon dioxide and other climate change-causing pollutants from space.

A further complicating factor is the rule-writing role of the U.S. and China, the two countries that head the Paris agreement’s committee on transparency and which are also the world’s top two carbon emitters. Washington has historically championed stronger transparency, but whether State Department diplomats will remain as invested in the issue given the nation’s current one-foot-out-the-door status is unclear.

China, meanwhile, has at times balked at efforts to assess its role in climate change. In the past, the country has shared its own internal statistics on emissions but has refused to answer questions about how those statistics were calculated. China’s data on coal use, a major contributor to its greenhouse gas emissions, has not always been reliable and, at times, the country has dramatically revised past reports. But Chinese President Xi Jinping is trying to position his country as a global leader on climate change, a mantle the U.S. dropped when President Barack Obama left office. Whether that means advocating for stronger transparency rules remains to be seen.

Ultimately, if the U.N. ends 2018 with strong rules on transparency, countries will have greater faith in the Paris agreement. They’ll know, with greater certainty, that what they’re doing is making a difference.

Looking beyond 2018, countries will begin offering up stronger and stronger emissions-cutting pledges. Once the rules are written, those undertakings are “the other critical task,” says Waskow. “Those together will put the Paris agreement fully into motion and make it a living, breathing thing with real consequence.”

The transparency rules will not just determine whether the world avoids a dangerous level of climate change — they will determine whether countries have faith in the U.N.’s delicate effort to protect the planet.
