New research suggests a broader view might be called for. A pair of often-overlooked sectors posted the largest rises in carbon dioxide pollution in the U.S. in 2018\. Emissions generated by industrial manufacturing jumped 5.7 percent, according to research firm Rhodium Group. Commercial and residential buildings generated ten percent more emissions. Those increases drove the 3.4 percent rise in overall pollution, the second-biggest year-over-year increase in the past 20 years. Transportation, which remains the U.S. economy’s largest source of carbon-dioxide, rose about 1 percent. The increase in pollution from buildings highlights a particular problem for policy makers. It’s strongly related to the weather — a warmer winter in 2017 suppressed demand for heating fuel and makes the return to normal in 2018 look like a spike. And while regulators can raise efficiency standards and change building codes for new construction, there’s not much they can do to control energy use in existing homes and offices. Manufacturing production increased last year, buoyed by a generally robust economy. But great news for factories can be a headache for carbon-cutters. “The industrial sector is still almost entirely ignored” by climate policy makers, the Rhodium authors write. These “forgotten sectors,” as the Rhodium authors call them, together make up about a third of U.S. carbon dioxide, with industrial sources contributing 22 percent and buildings 11 percent in 2016, according to the U.S. Environmental Protection Agency. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/5496630/pollution-manufacturing-buildings-2018-study/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/5496630/pollution-manufacturing-buildings-2018-study/"},"headline":"U.S. Carbon Emissions See Second Largest Year-On-Year Increase in 20 Years","datePublished":"2019-01-08T15:53:58.000Z","dateModified":"2026-08-04T07:53:01.103Z","description":"Commercial and residential buildings generated ten percent more emissions","url":"https://time.com/5496630/pollution-manufacturing-buildings-2018-study/","keywords":["Pollution","Environment","onetime"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt017d062eb723dc85/698942dab21a9c422d4ffdaf/pollution-rises-manufacturing-buildings.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Eric Roston / Bloomberg"}],"articleSection":"Science","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt017d062eb723dc85/698942dab21a9c422d4ffdaf/pollution-rises-manufacturing-buildings.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"pollution-rises-manufacturing-buildings","caption":"Los Angeles downtown and Hollywood","creditText":"Daniel Slim—AFP/Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/science/","name":"Science"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/pollution/","name":"Pollution"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/5496630/pollution-manufacturing-buildings-2018-study/","name":"U.S. Carbon Emissions See Second Largest Year-On-Year Increase in 20 Years"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"Life in the Most Polluted Capital in the World","description":"In Ulan Bator, the capital, respiratory infections have increased at a rate of 270% over the last 10 years and children living in the city have a 40% lower lung function than those living in rural areas, according to UNICEF.","thumbnailUrl":"https://cdn.jwplayer.com/v2/media/K40JhmZq/poster.jpg?width=720","uploadDate":"2018-03-22T10:18:41.000Z","contentUrl":"https://cdn.jwplayer.com/manifests/K40JhmZq.m3u8","embedUrl":"https://time.com/5496630/pollution-manufacturing-buildings-2018-study/","duration":"PT2M39S","potentialAction":{"@type":"SeekToAction","target":"https://time.com/5496630/pollution-manufacturing-buildings-2018-study/?jw_start={seek_to_second_number}","startOffset-input":"required name=seek_to_second_number"}}] ```
