    For Climate Change, Carbon Pricing is No Silver Bullet

    Many economists and policy experts believe carbon pricing is the most effective way to deal with global warming. But others argue that carbon pricing is not a silver bullet for dealing with climate change. Here’s why.

  • Carbon Pricing for the Climate: How It Could Work

    Carbon Pricing for the Climate: How It Could Work

    Most economists and policy experts agree that the most effective and cheapest way to curb the carbon dioxide emissions that are warming the planet is to “put a price on carbon.” How effective are carbon taxes and cap and trade programs?

  • Helping Senegalese Farmers with Smart Solar

    Helping Senegalese Farmers with Smart Solar

    An Earth Institute pilot project has brought smart solar power to farmers in Senegal, making agriculture more efficient, economical and sustainable.

    Trump vs. Clinton: What the Election Could Mean for Climate Policy

    The outcome of this year’s presidential election could have far-reaching implications for the fate of our planet because the two presumptive candidates, Democrat Hillary Clinton and Republican Donald Trump, have very different ideas about climate change. What will they do about the Paris accord and climate change?

  • The How and Why of Green Building

    The How and Why of Green Building

    Buildings account for almost a third of global greenhouse gas emissions and the U.N. Environment Programme projects that if we continue with business as usual in the building sector, these emissions will double by 2030. Fortunately, green building is on the rise around the world.

  • Making Fish Farming More Sustainable

    Making Fish Farming More Sustainable

    Global per capita fish consumption has almost doubled in the last 50 years. And today, about half of all the seafood we eat is produced through fish farming, aquaculture. Can it be done sustainably?

  • The Damaging Effects of Black Carbon

    The Damaging Effects of Black Carbon

    Air pollution, both outdoors and indoors, causes millions of premature deaths each year. The deaths are mainly caused by the inhalation of particulate matter, especially black carbon. But black carbon not only has impacts on human health, it also affects visibility, harms ecosystems, reduces agricultural productivity and exacerbates global warming.

  • What Five Tech Companies Are Doing About Climate Change

    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?

  • How Well is the World Protecting Ecosystems and Human Health?

    How Well is the World Protecting Ecosystems and Human Health?

    The new global environmental report card is out. The 2016 Environmental Performance Index graded 180 countries on how well they are protecting human health and their ecosystems. While the world is making progress in some areas, it is seriously falling behind in others.
