  • A Review of Electric Vehicle Consumer Subsidies in Canada

    A look at EV purchase subsidies in Canada, which have been introduced to accelerate market uptake of these vehicles as part of governments’ efforts to reduce greenhouse gas (GHG) emissions that contribute to climate change. Transportation accounts for almost one-quarter of Canada’s total GHG emissions, so it is not surprising that Canadian policymakers are focusing on emissions from this sector.

  • An update on eukaryotic viruses revived from ancient permafrost

    One quarter of the Northern hemisphere is underlain by permanently frozen ground, referred to as permafrost. Due to climate warming, irreversibly thawing permafrost is releasing organic matter frozen for up to a million years, most of which decomposes into carbon dioxide and methane, further enhancing the greenhouse effect. Part of this organic matter also consists of revived cellular microbes (prokaryotes, unicellular eukaryotes) as well as viruses that remained dormant since prehistorical times.

  • Pointless: the climate impact of frequent flyer status

    Frequent flyer programs (FFPs) are a key part of the business model of ‘full-service’ airlines, driving not just ticket sales, but increased flight provision.  FFPs increase air travel emissions by incentivising the most carbon-intensive seating options and encouraging additional flights. This article assesses the emissions associated with gaining different levels of membership in the frequent flyer programmes offered by British Airways and Virgin Atlantic.

  • Frequent Flying’s Dirtiest Habit: Mileage Runs

    Imagine taking a flight you don’t want or need, to stretch your legs in the destination airport before heading straight back. For years, frequent flyers have been taking mileage runs – also sometimes referred to as segment runs or tier point runs – solely to maximize the airline points or reward status they accrue. On message boards and social media, they trade nerdily specific details of flight routes, airline promotions, and reward tiers, calculating the exact itineraries that will bring them to a certain status or keep them there.

  • Not even the machines are rational

    For 50 years, behavioural economics has thrown the gauntlet at the rational expectation hypothesis and the concept of homo economicus. But now, rationality could fight back. AI and machine learning algorithms have become so powerful that their forecasts can compete with analyst forecasts (at least before transaction costs) and these algorithms certainly aren’t biased like humans are. Or are they?
