In September three MEPs convened a fruitful discussion on using remote sensing technology to measure pollutant emissions in vehicle exhaust in Europe’s cities.
The city is taking a big step forward in fighting air pollution, and other cities would benefit from doing the same.
The International Chamber of Shipping says that because our recent study shows that shipping emissions remain below their 2008 peak, not to worry. That's an overly rosy view of the data.
As the International Maritime Organization meets again in London to discuss a sectoral cap on greenhouse gas emissions, we revisit the complexity of how to assign responsibility for shipping emissions. Both countries that offshore their shipping emissions, and the flag states that absorb them, are identified. We close with a few useful principles for policymakers.
The EC’s proposed mandate can indeed be an important step toward advanced biofuels, but it can and should do more to avoid unintended consequences. Improving the sustainability criteria defined in the mandate will help ensure that it reduces life-cycle GHG emissions without harming the environment in other ways.
Next year, EPA has the chance to propose an ambitious GHG standard for aircraft to promote low carbon aviation. It alluded to the possibility of going further than the UN’s weak recommendations in the 2016 endangerment finding, where it argued that it would set aircraft standards “at least as stringent as ICAO’s.” Here’s hoping that EPA agrees with Boeing, GE, and, yes, ICCT and goes further than ICAO’s least common denominator standard.
