ABSTRACT

Both Canada and the US have mandated biofuels’ use in transport fuel. However, while Canadian biofuel mandates have been largely uncontroversial, US biofuels mandates have been subject to considerable controversy. To explain this cross-national difference, the article examines media coverage of advanced biofuels in American and Canadian newspapers over 2010–2016 and developments with respect to the implementation of advanced biofuel mandates. It finds that while the two countries share commonalities in media frames of advanced biofuels, the overall tone of coverage in the US is much more negative than in Canada. The negative and positive media coverage parallel policy developments in the two countries, suggesting their interactive effects in stabilizing or destabilizing biofuel policies.

摘要

加拿大和美国都已授权在运输燃料中使用生物燃料。但是，尽管加拿大的生物燃料指令在很大程度上没有争议，但美国的生物燃料指令却受到了很大的争议。为了解释这种跨国差异，本文研究了美国和加拿大报纸在2010-2016年期间对先进生物燃料的媒体报道以及在执行先进生物燃料指令方面的发展。研究发现，尽管两国在先进生物燃料的媒体框架中具有共同点，但美国的总体报道基调远不如加拿大。媒体报道的消极和正面影响了两国的政策发展，表明它们在稳定或破坏生物燃料政策方面的互动作用。
