As delegates at COP22 in Marrakech convene to discuss how to implement the Paris Agreement, there is a continuing focus on how to move to a sustainable global energy system. The challenge is that fossil fuels have long been the mainstay of the energy system, and an essential driver of growth. Rapidly reducing our reliance on their use is no small task, but one that is essential if we are to succeed in achieving the climate ambition set out in the December 2015 Paris Agreement.  The challenge is brought sharply into focus when we consider that the global energy system accounts for 65% of anthropogenic GHG emissions[1], but will need to be a net zero-emitter at some point between 2050 and 2100.

The challenge

The barriers to this transition are immense. (more…)

The highs and lows at the United Nations International Maritime Organisation’s 70th Marine Environment Protection Committee

pixa-shipOn 24-28 October 2016, two weeks before the Marrakech COP22, the International Maritime Organization (IMO)- the UN’s body responsible for regulating shipping, met for the 70th session of the Marine Environment Protection Committee (MEPC). With a heavy agenda on the table, colleagues from UMAS closely followed two key agenda items, review of the implementation date for a sulphur cap (item 5), and, reduction of GHG emissions from ships (item 7).

On the first day of the committee meeting Dr Tristan Smith and Carlo Raucci along with the lead authors of the study presented the findings of the IMO fuel availability study as a side event presentation. The presentation was followed by another study using the same terms of reference but coming to a contrasting conclusion. (more…)

Emit now, pay later: The case of shipping and its GHG emissions

Something we’ve got used to in our daily purchasing habits is the term ‘buy now pay later’. Whilst this may be good for our personal lifestyles and ease the cash flow somewhat, we still have to pay, only later and usually with added interest. The same goes for our climate: we emit now, but due to finite CO2 budgets, we will ultimately have to pay and it is up to us to decide whether we prefer drastic mitigation or adaptation action as payment. For quite some time shipping, which accounts for approximately 2-3% of global CO2 emissions, has dodged the emissions regulatory bullet for various reasons (relative to other sectors), one of them being the public’s lack of awareness of the industry. Unless you live next to a busy port, you probably don’t think too much about the global shipping industry and its carbon footprint. (more…)
