  • Available data suggest that, in addition to the obvious catches of fish for human needs, the by- catches in the world’s fisheries have a significant ecological impact and cause mortality amongst fin-fish (particularly the juveniles of commercial fish species), as well as amongst benthic invertebrates, marine mammals, turtles and birds.

  • Climate impacts were monetized using estimates of the social cost of carbon—the valuation of the damages due to emissions of one metric ton of car- bon, of $30/ton of CO2equivalent (CO2e), 20 with low and high estimates of $10/ton and $100/ton. There is uncertainty around the total cost of climate change and its present value, thus uncertainty con- cerning the social cost of carbon derived from the total costs.

  • The prototypical catalytic reductiveC–Cbond formations, the Fischer-Tropsch reaction [1] and alkene hydroformylation [2], were discovered in 1922 and 1938, respectively [3,4]. These processes, which involve reductive coupling to carbon monoxide, have long been applied to the industrial manufacture of commodity chemicals [5]. Notably, alkene hydroformylation, also known as the oxo-synthesis, has emerged as the largest volume application of homogeneous metal catalysis, accounting for the production of over 7 million metric tons of aldehyde annually.
