The solar-powered compactor packs 16 yards of loose trash into just 4 yards, reducing waste pick-up at the busy property to just once per week, thus slashing hauling costs by 50 percent, reducing CO2 emissions by more than 14 tons annually, and importantly limiting garbage truck noise to guests and neighboring residents.

Turn off your air conditioner and stay cool in your shirt instead. That's the idea behind a new plastic-wrap-like material that Stanford University scientists say could be made into "cool" clothing, the use of which could slash emissions and energy consumption in buildings. If woven into fabric, the wearable cloth could keep humans cool on the hottest of days, eliminating the need to adjust the thermostat or crank up a fan. That could make a dent on a major source of U.S. greenhouse gases, the researchers say.

A planned 650MW combined-cycle gas turbine power station in Indiana will reduce the rate of sulfur dioxide, nitrogen oxide and particulate matter emissions by more than 98 percent and water use by 97 percent.

NRG Energy announced new long-term sustainability targets, which include slashing carbon-dioxide emissions from 2014 levels 50 percent by 2030 and 90 percent by 2050.

Kellogg has announced new science-based emissions targets to reduce greenhouse gas emissions across its operations 65 percent and help its suppliers reduce their emissions 50 percent by 2050 against a 2015 baseline.

In its proposal to host the 2024 Olympic games, the Paris bid committee proposed a plan that would cut the event's carbon emissions by more than 50% compared with the last two Olympic games. It involves providing public or shared transportation for all game spectators and housing most athletes less than 30 minutes from their events.

Necker Island, a small Caribbean island owned by business icon Richard Branson, has signed a contract to slash its diesel fuel use by building a renewable energy-powered microgrid.

California Gov. Jerry Brown (D) proposed Monday to cut in half the gasoline and diesel fuel used by vehicles and get half the state's electricity from renewable sources.

New report suggests smart city technologies capable of slashing greenhouse gas emissions and air pollution are on the cusp of a major breakthrough

San Diego Gas & Electric expects its new water-wise landscaping project at Century Park, its Kearny Mesa headquarters, to save the utility more than 4 million gallons of water a year, a 40 percent campus reduction.

Renewable energy and efficiency strategies are saving America's biggest companies well over $1 billion a year, according to a new report from Ceres and the World Wildlife Fund. Led by UPS, the 53 Fortune 100 companies that report carbon reductions saved $1.1 billion annually and slashed their carbon diozide emissions by the equivalent of 15 coal-fired power plants

Kellogg has announced new science-based emissions targets to reduce greenhouse gas emissions across its operations 65 percent and help its suppliers reduce their emissions 50 percent by 2050 against a 2015 baseline.

But for ice cream super brand Ben & Jerry's, carbon pricing is already a reality, allowing the scheme to pay U.S. dairy farmers to invest in onsite renewable energy generation and other clean technologies as it looks to slash its supply chain emissions.

Existing buildings in New York will now face higher standards for the emissions of greenhouse gases by upgrading water heaters, boilers and roofs, among other changes. The goal is to cut greenhouse gas emissions in the city by 7% by 2035.

Research published in the American Journal of Primatology earlier this month finds that the overall Western Chimpanzee population declined by six percent annually between 1990 and 2014, a total decline of 80.2 percent. The main threats to the Western Chimpanzee are almost all man-made. Habitat loss and fragmentation driven by slash-and-burn agriculture, industrial agriculture (including deforestation for oil palm plantations as well as eucalyptus, rubber, and sugar cane developments), and extractive industries like logging, mining, and oil top the list. In response to the finding that the Western Chimpanzee population has dropped so precipitously in less than three decades, the International Union for the Conservation of Nature (IUCN) elevated the subspecies' status to Critically Endangered on its Red List of Threatened Species.

Deep learning AI has been put to work in intelligent drones, sequencing genomes, learning the tactics of the ancient Chinese board game Go, and even keeping cats off the lawn. Now, Google has set its DeepMind system loose on its massive data centers, and drastically cut the cost of cooling these facilities in the process.

As evidence mounts that excessive use of light is harming wildlife and adversely affecting human health, new initiatives in France and elsewhere are seeking to turn down the lights that flood an ever-growing part of the planet

HP became the first high-tech company to set specific greenhouse gas (GHG) emissions reduction goals across its suppliers and business partners and an aggressive one at that: 20 percent by 2020, compared with 2010 levels.

The French Government passed legislation to cut the country's energy consumption 50% by 2050, reduce nuclear power production to 50% of the energy mix, and increase renewable energy to 32% of total energy consumption by 2030. The law also requires the country to reduce its carbon emissions 40% by 2030, compared to 1990 levels.

The International Panel on Climate Change has already warned of irreversible damage linked to greenhouse gas emissions and called for an 80-percent reduction of power-sector emissions by 2050. "We decided to go a little further."
