<p><strong>Synopsis</strong></p>
<p>Harry Clark, NZAGRC Director, opened the afternoon session of the conference with a talk about &ldquo;realities, magic potions and clairvoyance&rdquo;. Harry highlighted the fact that there are a number of solutions that are available to reduce agricultural GHGs now. These include increasing farm efficiency, using different feeding strategies and reducing N fertiliser use. In his role, he sees a number of magic potions being promoted though. Feed additives that claim to reduce methane need to be carefully examined. Many of these need to go into the diet at a high concentration in order to be effective. Additionally, the active compounds may have unintended side effects, even if they come from a &lsquo;natural&rsquo; source. LCA of any supplements also need to be considered to avoid trading one negative environmental effect for another one. New technologies are required in order to hit the Paris Agreement target. There is unlikely to be a silver bullet, so a basket of options will be the most likely solution. Future New Zealand&nbsp;emissions are highly dependent on the size of the livestock sector, so this is something that a range of stakeholders will be considering going forwards.</p>
