Global Carbon Emissions Rise for First Time Since 2014
Global carbon dioxide emissions from energy increased for the first time in 2017 after three years of remaining flat, the International Energy Agency (IEA) said Thursday, meaning the world remains far off course in curbing planet warming emissions.
Carbon emissions reached a record-high of 32.5 gigatonnes in 2017 due to global economic growth and increased energy demands that was met mostly by fossil fuels. As the Financial Times noted, that growth—an increase of 460 million tonnes—is the equivalent to the emissions of an additional 170 million cars.
These findings are part of the Paris-based IEA's "Global Energy and CO2 Status Report" released today.
The report shows that global energy demand rose by 2.1 percent last year (or 14,050 million tonnes of oil equivalent), more than twice the rate in 2016. Oil, natural gas and coal met more than 70 percent of additional need, while renewable energy met just about the rest.
Global energy-related CO2 emissions grew by 1.4 percent in 2017, reaching a historic high of 32.5 gigatonnes, a resumption of growth after three years of global emissions remaining flat.Global Energy & CO2 Status Report
"The significant growth in global energy-related carbon dioxide emissions in 2017 tells us that current efforts to combat climate change are far from sufficient," said Fatih Birol, IEA executive director, in a statement.
"For example, there has been a dramatic slowdown in the rate of improvement in global energy efficiency as policy makers have put less focus in this area."
The IEA's findings "demonstrates that current efforts are insufficient to meet the objectives of the Paris Agreement," the report says. The 2015 Paris agreement set a primary goal to limit global warming well below 2°C to avoid dangerous climate tipping points.
"Global emissions need to peak soon and decline steeply to 2020; this decline will now need to be even greater given the increase in emissions in 2017," the report says.

However, this increase was not universal. While most major economies saw a rise, others such as the U.S., UK, Mexico and Japan experienced declines in CO2 emissions.
Interestingly, the greatest decline came from the U.S., where emissions fell by 0.5 percent, the third consecutive year of decline. This is despite President Trump's push for fossil fuels and his intention to withdraw from the Paris agreement.
The reason behind the drop? Mainly because of higher deployment of renewables. In the U.S., a record 17 percent of electricity generation was from renewables last year. According to the report, 10 gigawatts of solar PV was added in 2017, down 30 percent relative to 2016 but still the second highest year on record.
The report also highlighted the clean energy strides of another major global polluter and the world's largest heat consumer: China.
"China's economy grew nearly 7 percent last year but emissions increased by just 1.7 percent (or 150 Mt) thanks to continued renewables deployment and faster coal-to-gas switching."
Asian economies accounted for two-thirds of the global increase in carbon emissions.Global Energy & CO2 Status Report
Renewable energy played the most important role in the growth of low-carbon energy, the report points out. The sector saw the highest rate of growth of any energy source in 2017, and met around a quarter of global energy demand growth last year.
Here are other key findings of the IEA report:
- Oil demand grew by 1.6 percent, more than twice the average annual rate seen over the past decade, driven by the transport sector (in particular a growing share of SUVs and trucks in major economies) as well as rising petrochemical demand.
- Natural gas consumption grew 3 percent, the most of all fossil fuels, with China alone accounting for nearly a third of this growth, and the buildings and industry sectors contributing to 80 percent of the increase in global demand.
- Coal demand rose about 1 percent, reversing declines over the previous two years, driven by an increase in coal-fired electricity generation mostly in Asia.
- Renewables had the highest growth rate of any fuel, meeting a quarter of world energy demand growth, as renewables-based electricity generation rose 6.3 percent, driven by expansion of wind, solar and hydropower.
- Electricity generation increased by 3.1 percent, significantly faster than overall energy demand, and India and China together accounting for 70 percent of the global increase.
- Energy efficiency improvements slowed significantly, with global energy intensity improving by only 1.7 percent in 2017 compared with 2.3 percent on average over the last three years, caused by an apparent slowdown in efficiency policy coverage and stringency and lower energy prices.
- Fossil fuels accounted for 81 percent of total energy demand in 2017, a level that has remained stable for more than three decades.

Since even moderate-intensity workouts offer a slew of benefits, walking is a good choice for people looking to stay healthy.
How to Rock Your Walk<p>Walking isn't just fun and healthy. It's accessible.</p><p>"Walking is cheap," says Dr. John Paul H. Rue, a sports medicine doctor at <a href="https://mdmercy.com/" target="_blank">Mercy Medical Center in Baltimore</a>. "You can do it anywhere at any time; [it] requires little to no special equipment and has many of the same cardio benefits as running or other more intense workouts."</p><p>Want to up your walking game? Try the tips below.</p>
Use Hand Weights<p>Cardio and strength training can go hand-in-hand when you add weights to your walk.</p><p>A <a href="https://journals.lww.com/acsm-msse/Fulltext/2019/03000/Associations_of_Resistance_Exercise_with.14.aspx" target="_blank">2019 study</a> found that weight training is good for your heart, and <a href="https://www.mayoclinicproceedings.org/article/S0025-6196(17)30167-2/abstract" target="_blank">research</a> shows it reduces the risk of developing a <a href="https://www.healthline.com/health/nutrition-metabolism-disorders" target="_blank">metabolic disorder</a> by 17 percent. People with metabolic disorders have a higher chance of being diagnosed with high cholesterol, high blood pressure, and diabetes.</p><p>Rue suggests not carrying weights for your entire walk.</p><p>"Hand weights can give you an added level of energy burning, but you have to be careful with these because carrying [them] over a long period of time or while walking could actually lead to some overuse injuries," he says.</p>
Make It a Circuit<p>As another option, consider doing a circuit. First, put a pair of dumbbells on your lawn or somewhere in your home. Walk around the block once, then stop and do some bicep curls and tricep lifts before walking around the block again.</p><p>Rue recommends <a href="https://www.healthline.com/health/exercise-fitness/running-with-weights" target="_blank">avoiding ankle weights</a> during cardio workouts, as they force you to use your quadriceps rather than hamstrings. They can also cause muscle imbalance, according to the <a href="https://www.health.harvard.edu/staying-healthy/wearable-weights-how-they-can-help-or-hurt" target="_blank">Harvard Health Letter</a>.</p>
Find a Fitness Trail<p>Strength training isn't limited to weights. You can get stronger by <a href="https://www.healthline.com/health/bodyweight-workout" target="_blank">simply using your body</a>.</p><p>Often found at parks, fitness trails are obstacle courses with equipment for pullups, pushups, rowing, and stretches to build upper and lower body strength.</p><p>Try searching "fitness trails near me" online, checking out your local parks and recreation website, or calling the municipal office to <a href="https://calisthenics-parks.com/" target="_blank">find one</a>.</p>
Recruit a Friend<p>People who workout together stay healthy together.</p><p><a href="https://bmcgeriatr.biomedcentral.com/articles/10.1186/s12877-017-0584-3" target="_blank">One study</a> showed that older adults who exercised with a group improved or maintained their functional health and enjoyed their lives more.</p><p>Enlist the help of a walking buddy with a regimen you aspire to have. If you don't know anyone in your area, apps like <a href="https://www.strava.com/" target="_blank">Strava</a> have social networking features so you can get support from fellow exercisers.</p>
Try Meditation<p>According to the <a href="https://www.nccih.nih.gov/research/statistics/nhis/2017" target="_blank">2017 National Health Interview Survey</a>, published by the National Institutes of Health, meditation is on the rise, and for good reason.</p><p>Researchers <a href="https://pubmed.ncbi.nlm.nih.gov/29616846/" target="_blank">found</a> that mind-body relaxation practices can regulate inflammation, <a href="https://www.healthline.com/health/biological-rhythms" target="_blank">circadian rhythms</a>, and <a href="https://www.healthline.com/health/glucose" target="_blank">glucose</a> metabolism, as well as lower <a href="https://www.healthline.com/health/high-blood-pressure-hypertension" target="_blank">blood pressure</a>.</p><p>"Any form of exercise can be turned into a meditation of some type, either by the surroundings you are walking in, like a park or trail, or by blocking out the outside world with music on your headphones," Rue says.</p><p>You can also play a podcast or download an app like <a href="https://www.headspace.com/headspace-meditation-app" target="_blank">Headspace</a> that has a library of guided meditations to practice while you walk.</p>
Do Fartlek Walks<p>Typically used in running, fartlek intervals alternate periods of increased and decreased speed. These are <a href="https://www.healthline.com/nutrition/benefits-of-hiit" target="_blank">high-intensity interval training (HIIT)</a> workouts, which allow exercisers to accomplish more in less time.</p><p><a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0154075" target="_blank">One study</a> showed that 10-minute interval training improved <a href="https://www.healthline.com/health/metabolic-syndrome" target="_blank">cardiometabolic</a> health, or lowered the risk of heart disease, stroke, and diabetes, just as well as working out at a continuous pace for 50 minutes.</p><p><a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0111489" target="_blank">Research</a> also shows that HIIT workouts increase muscle <a href="https://www.healthline.com/health/fast-twitch-muscles" target="_blank">oxidative</a> capacity, or the ability to use oxygen. To do a fartlek walk, try walking at an increased pace for 3 minutes, slow down for 2 minutes, and repeat.</p>
Gradually Increase Pace<p>A faster walking pace is associated with a lower risk of <a href="https://www.healthline.com/health/copd" target="_blank">chronic obstructive pulmonary disease (COPD)</a> and respiratory diseases, according to a <a href="https://pubmed.ncbi.nlm.nih.gov/30303933/" target="_blank">2019 study</a>.</p><p>Still, it's best not to go from a stroll to an Olympic-worthy power walk in a day. Instead, increase your pace gradually to prevent injury.</p><p>"Start by walking at a brisk pace for about 10 minutes per day, 3 to 5 days per week," Rue says. "Once you've done this for a few weeks, increase your time by 5 to 10 minutes per day until you get to 30 minutes."</p>
Add Stairs<p>You've likely heard that taking the stairs instead of an elevator is a way to add more movement into your daily routine. It's also a way to step up your walking. Stair climbing has been shown to <a href="https://www.sciencedirect.com/science/article/pii/S2211335519301123?via%3Dihub" target="_blank">decrease the risk of mortality</a> and can easily add a bit more challenge to your walk.</p><p>If you don't have stairs in your home, you can often find them outside a local municipal building, train station, or at a high school stadium.</p>
Is Your Walk a True Cardio Workout?<p>Not all walks are equal. A walk that's too leisurely may not provide enough burn to qualify as cardio. To see if you're getting a good workout, try to <a href="https://www.healthline.com/health/how-to-check-heart-rate" target="_blank">measure your heart rate</a> using a monitor.</p><p>"A target goal for a good walking workout heart rate is about 50 to 70 percent of your maximum heart rate," Rue says, adding that maximum heart rate is <a href="https://www.healthline.com/health/fitness-exercise/fat-burning-heart-rate" target="_blank">typically calculated</a> by 220 beats per minute minus your age.</p><p>You can also monitor how easily you can carry on a conversation while you walk to gauge your heart rate.</p><p>"If you can walk and carry on a normal conversation, that's probably a lower intensity walk," says Rue. "If you are slightly breathless but can still have a conversation, that's probably a moderate workout. If you are out of breath and can't talk normally, that's a vigorous workout."</p>
Takeaway<p>By shaking up your routine, you can add excitement to your workout and reap even more rewards than a basic walk provides. Increasing the pace and intensity of a workout will make it more effective.</p><p>Simply pick your favorite variation to add some spice to your next walk.</p>

Summer and fall are great seasons to enjoy the outdoors. But if you're already spending extra time outside because of the COVID-19 pandemic, you may be out of ideas on how to make fresh-air activities feel special. Here are a few suggestions to keep both adults and children entertained and educated in the months ahead, many of which can be done from the comfort of one's home or backyard.
The coronavirus may linger in the air in crowded indoor spaces, spreading from one person to the next, the World Health Organization acknowledged on Thursday, as The New York Times reported. The announcement came just days after 239 scientists wrote a letter urging the WHO to consider that the novel coronavirus is lingering in indoor spaces and infecting people, as EcoWatch reported.
