My understanding of ‘carbon offset’ used to be neutralising carbon emissions by planting trees that would absorb the same quantity of carbon dioxide that you caused to be produced. But recently I learnt that tree-planting alone isn’t realistic enough in countering our growing rate of emissions, & there are also many other types of carbon offsets designed to permanently reduce future emissions & dependency on fossil fuels, eg. renewable energy plants, improved forest management, waste management, & efficient cooking stoves for less developed communities. 以前我對「碳抵消」嘅認識僅止於通過植樹項目來中和碳排放，原理上新種植嘅樹木可以吸收等同人類活動所造成嘅二氧化碳💨。但最近我了解到單單以植樹來抵消不斷增長嘅碳排放係唔現實嘅，原來仲有許多不同類型嘅碳抵消計劃，如專研再生能源、改善森林管理、廢物管理及在發展中社區提供高效爐灶等，可更有效長遠地降低碳排放同對化石燃料嘅依賴。
A carbon offset is a reduction in emissions of CO2 or other GHGs in order to compensate for emissions made elsewhere that’s unavoidable. In a way it’s like crowdfunding for climate action: buying Certified or Voluntary Emission Reductions (CERs, VERs) is a direct financial contribution to responsible projects that bring down emissions while benefiting communities around them. There’s no way to prove additionality of the projects with certainty - that’s why it’s important to offset via certification systems like the Gold Standard & UN that offer extra credibility. Check out @ecoinprogress post for more reliable sources of offsets! 碳抵消就係透過各種減少溫室氣體排放嘅項目，來彌補其他地方無法避免嘅碳足印，整體減輕全球暖化。某程度上，碳抵消就像為氣候行動進行眾籌：購買核證或自願認證減排量來直接資助減排項目，同時令周邊社區受益。當然，我們冇辦法知道碳抵消係咪有真正積極嘅效果， 所以更要支持經Gold Standard或聯合國認正嘅項目。 .
Last but not least, offsetting carbon is NOT a way of avoiding changes to un-environmentally friendly ways of living. To support the transition to a low-carbon sustainable future, we must be responsible for our own carbon footprint & take climate conscious steps to reduce emissions in the first place. Airlines often offer the option to offset CO2 emissions generated from flight travel. @cathaypacific allows passengers to contribute towards offset projects validated by the Gold Standard & it’s totally affordable. 要緊記，碳抵消唔係一個可以俾人繼續唔環保嘅藉口，紓緩氣候變化始終需要從節約能源開始。為了低碳可持續嘅未來，我地需要對自己嘅碳足跡負責，並時刻實踐減排。航空公司也會提供抵消飛行所產生的碳排放選項呢。
