demarcation
COP21では，各国の合意を目指して話し合いが続けられております。フランス外務省によると，議論は良い方向に進んでいるが，合意に向けてはさらなる妥協が必要となると述べております。
記事の中で気になった単語は"demarcation"です。『Wisdom英和辞典第三版』（三省堂）によると「境界, 限界; 境界画定, 限界設定，区分，分離」などという意味がありました。ODには"The action of fixing the boundary or limits of something"と定義されております。ODの語源を見ると，18世紀初頭にスペイン語として誕生した"demarcion"に由来するようです。（Ume）
COP21: Climate deal due Saturday after more all-night talks

The richer countries were also insisting on a single system of verification of promises for all countries.
"We feel that when parties have committed themselves to a national target that reflects their ambitions and abilities, they must be ready to tell the global community what type of progress is being made," said Elina Bardram, the EU's chief negotiator told reporters.
"We need to have accounting standards and principles that are common to all - otherwise you are simply comparing apples with pears."
