  • Questioning Carbon Capture and Storage

    Questioning Carbon Capture and Storage

    With billions of dollars around the world being invested into carbon capture and storage, often in the energy sector, there are compelling questions to ask about when, where and for what purpose we use this technology.

    What Five Tech Companies Are Doing About Climate Change

    Many experts agree that the climate pledges made at COP21 alone will not hold global temperatures below 2˚ C—we also need significant investment in energy technology innovation in order to meet the climate goals. What are the five big tech companies and their founders doing about climate change?

  • A Sustainable Lifestyle and the Changing Nature of Work

    In the process of changing the economic role of the city, we need to pay more attention to the impact of our production and consumption on the environment and on all elements of the supply chain that bring goods and services to us. Building systems that reduce environmental impacts is more important than individual consumption…

  • Volkswagen Needs to Adopt 21st Century Sustainability Management

    While it is true that many nations do not enforce their environmental and occupational health and safety rules, a quick study of economic history demonstrates that the trend is toward more enforcement rather than less enforcement. And even when the government ignores noncompliance with the law, NGOs and consumers notice it.

  • Where is Solar Power Headed?

    Where is Solar Power Headed?

    To have a shot at curbing the worst impacts of climate change, we need to extricate our society from fossil fuels and ramp up our use of renewable energy. Where does solar energy stand today, and where does it need to go in order for us to make the transition to renewable energy?

  • The Race for Better Batteries

    The Race for Better Batteries

    The worldwide transition from fossil fuels to renewable sources of energy is under way, but to integrate all this variable power into the grid, battery storage is key. Researchers around the world are working on developing better and cheaper batteries.

  • ‘The Big Ratchet’

    ‘The Big Ratchet’

    In her new book, Ruth DeFries argues that we have continually created new technologies that allow our numbers to grow. But each new invention creates a new problem—which we solve with yet another innovation that creates the next problem. Will we be able to sustain this so-far successful cycle past the great leap in technology…

    For a Wind-Powered City, Heat Pumps Are Key

    Replacing conventional building boilers with electric heat pumps in New York City buildings could substantially increase the viability of renewable energy use in the city, according to a recent study from researchers from the Earth Institute’s Sustainable Engineering Lab.

    EPA’s Upcoming Carbon Rules: A Primer

    On Monday, June 2, President Obama will announce proposed federal rules aimed at curbing carbon emissions from existing U.S. power plants–possibly a landmark in U.S. climate policy. It is uncertain how far the rule will go, and the announcement is being closely watched around the world.
