Paris Climate Goals Can Be Reached Without Carbon Capture Tech, Landmark Study Finds
A groundbreaking study by the International Institute for Applied Systems Analysis (IIASA) is the first to map a pathway to limiting warming to 1.5 degrees Celsius above pre-industrial levels without relying on negative emissions technologies that suck carbon dioxide from the the atmosphere, an IIASA press release reported.
Instead, the study published Monday in Nature Energy found that the more ambitious Paris agreement target can be reached through innovations in the energy efficiency of daily activities. Changes to heating, cooling, transport, appliances and technological devices could both limit climate change and meet the UN Sustainable Development Goals to improve quality of life in the global South, the study found.
"Our analysis shows how a range of new social, behavioral and technological innovations, combined with strong policy support for energy efficiency and low-carbon development can help reverse the historical trajectory of ever-rising energy demand," IIASA acting program director and lead study author Arnulf Grubler said in the press release.
The report focused on innovations that were currently available and calculated what would happen if they were applied at scale. It found that doing so could reduce the energy required for transportation, heating and cooling and meeting the physical needs of the world's population by two to four times.
The paper further explained that the success of its scenario relied on the willingness of populations, governments and businesses to make the changes it advocates.
"The global community from world leaders and multinational corporations down to individual consumers and citizens need to act in concert to avoid dangerous climate change while improving human wellbeing. Our scenario offers a roadmap as to how this can be achieved," Grubler said.
Markers on that roadmap included ride-sharing fleets of electric vehicles that could reduce transport energy demand by 60 percent by 2050. Increased energy standards for new buildings and renovations for old ones could reduce energy demand from heating and cooling by 75 percent by 2050. The report further found that changing individual habits on a global scale could make a huge difference. The expanded use of smartphones to do the work of what would have previously been several devices, accompanied by a shift in the younger generation from owning material goods to accessing services as needed could limit the growth in global energy demand to 15 percent by 2050. And following a healthy diet that replaced red meat calories with something else could lower agriculture energy demand and lead to increased forest cover the combined size of Bangladesh and Italy by 2050.The report concluded that reducing overall global energy demand 40 percent by 2050, combined with projected renewable energy growth, would succeed in limiting warming 1.5 degrees without the need for negative emissions.

‘Companies Should Not Be Allowed to Use Hazardous Ingredients in Products People Use’: Michelle Pfeiffer Speaks Up for Safer Cosmetics
The beauty products we put on our skin can have important consequences for our health. Just this March, the U.S. Food and Drug Administration (FDA) warned that some Claire's cosmetics had tested positive for asbestos. But the FDA could only issue a warning, not a recall, because current law does not empower the agency to do so.
Michelle Pfeiffer wants to change that.
The actress and Environmental Working Group (EWG) board member was spotted on Capitol Hill Thursday lobbying lawmakers on behalf of a bill that would increase oversight of the cosmetics industry, The Washington Post reported.

Scientists at the United Nations' intergovernmental body focusing on biodiversity sounded alarms earlier this month with its report on the looming potential extinction of one million species — but few heard their calls, according to a German newspaper report.
The climate crisis is a major concern for American voters with nearly 40 percent reporting the issue will help determine how they cast their ballots in the upcoming 2020 presidential election, according to a report compiled by the Yale Program on Climate Change Communication.
Of more than 1,000 registered voters surveyed on global warming, climate and energy policies, as well as personal and collective action, 38 percent said that a candidate's position on climate change is "very important" when it comes to determining who will win their vote. Overall, democratic candidates are under more pressure to provide green solutions as part of their campaign promises with 64 percent of Democrat voters saying they prioritize the issue compared with just 34 percent of Independents and 12 percent of Republicans.
President Donald Trump has agreed to sign a $19.1 billion disaster relief bill that will help Americans still recovering from the flooding, hurricanes and wildfires that have devastated parts of the country in the past two years. Senate Republicans said they struck a deal with the president to approve the measure, despite the fact that it did not include the funding he wanted for the U.S.-Mexican border, CNN reported.
"The U.S. Senate has just approved a 19 Billion Dollar Disaster Relief Bill, with my total approval. Great!" the president tweeted Thursday.
