Are We at Peak CO2 Emissions?

Sometimes there’s good news about climate change

News emerged last week that the world might have turned a corner in the effort to preserve a livable planet. A peak in carbon dioxide emissions could mark a pivotal shift in the climate battle. It’s important for journalists to convey the importance of this news — and to understand what it does and doesn’t mean.

The New York Times reported on May 30 that “global carbon dioxide emissions may have peaked last year.” The Times attributed this eye-catching finding to a new BloombergNEF report, which maps out two credible scenarios: one in which governments take aggressive action to get to net zero emissions by 2050, and one in which emissions fall only by economic forces and technical innovations. In both scenarios, BNEF projects that “energy-related” global CO2 emissions peaked in 2023 and will fall for the rest of the decade.

These projections will obviously need to be confirmed by real-world measurements. But the global NGO Climate Analytics released a report last year calculating a 70% chance that CO2 emissions will start falling this year “if current clean technology growth trends continue and some progress is made to cut non-CO2 emissions.” The International Energy Agency, meanwhile, predicts that global fossil fuel demand — the number one driver of CO2 emissions — will peak by 2025.

There are a couple important caveats. The text of the BNEF report does not explicitly mention that emissions peaked in 2023 — there is always a possibility those projections could change. And the peak refers only to emissions from power plants, vehicles, buildings, and other elements of the energy system, which make up about 80% of the world’s CO2 emissions.

Nevertheless, a peak could be a big deal. The BNEF report shows that aggressive actions could further reduce emissions to net zero by 2050, although global temperatures would still rise to 1.75 degrees Celsius above pre-industrial levels, overshooting the Paris Agreement’s 1.5-degree-C target.

But peaking annual CO2 emissions is only a first step toward what scientists say is required to avoid a catastrophic overheating of the planet. Think of the atmosphere like a bathtub close to overflowing, while annual emissions are the water coming out of the tap. Until we stop annual emissions, the level of water in the tub will keep rising. And even if we turn off the tap, the tub will still remain dangerously full. So, if and when annual emissions go to zero, humans must also figure out ways to “drain the bathtub” by extracting CO2 from the atmosphere.

All this provides journalists with an opportunity to do constructive and rigorous climate solutions reporting. It’s important to share this new data with audiences and carefully explain what it does and doesn’t mean. The road ahead remains long and challenging, but the new data suggest that cutting emissions is not only a planetary imperative but an achievable goal. That’s good news.

No fossil fuel ads. In a blistering speech marking World Environment Day, UN Secretary-General António Guterres blasted fossil fuel companies as “enablers to planetary destruction” and called for banning their advertising. Noting that some governments have restricted advertising tobacco because it harms human health, Guterres urged “every country to ban advertising from fossil fuel companies. And I urge news media and tech companies to stop taking fossil fuel advertising.” By Jamey Keaten at the Associated Press…
