2030年就在眼前。因此，许多公司，包括业主和租户，都在审视他们所设定的可持续发展承诺，特别是针对1类和2类排放，并想知道如何弥合当前和目标绩效之间的差距。
世邦魏理仕的研究显示，亚太地区55%的租户调查受访者承诺实现净零排放，其中大多数人承诺到2030年实现净零排放。所有这些组织都必须考虑与其房地产投资组合相关的排放，这将构成其范围1和2排放足迹的一部分（如果不是大部分的话）。
包括新加坡在内的各国政府都有自己的承诺要履行，并通过强制性气候报告以及建筑管理局（BCA）强制性效率改进等举措，进一步加大了对企业的压力。
为了支持这一点，各组织正致力于通过能源效率和可再生能源的采购和生产来减少能源消耗。这听起来很简单；然而，我们确实看到了使这些变化成为现实的重大挑战。
一个关键的挑战是，房东和租户高度依赖对方做出改变，才能真正看到影响。在多出租资产中，占用者的排放量可能占建筑总排放量的70%以上。然而，业主通常是被期望改善资产表现的人。
这就导致了激励机制分裂的挑战，这是房地产行业实施可持续发展举措的主要障碍。
房东对投资节能和可再生能源犹豫不决，因为他们看不到回报，而房客则从相关的节能中获益。
租户不太可能投资设备或固定装置来提高能源效率，因为他们要么投资房东的设备，要么投资在租期结束时必须拆除的设备。
在单租物业中，这可能不是一个问题，因为租户对建筑物拥有完全的控制权，他们将是看到投资收益的人。然而，对于房东来说，让租户与他们的可持续发展议程保持一致仍然存在挑战。

为了解决这个问题，企业开始寻求绿色租赁。绿色租赁是指业主和租户之间的租赁和协议，旨在减少资产对环境的影响，促进建筑运营的可持续性。
它们通常包括与跨党派协作、数据共享、公用事业绩效、变更、健康和福利、废物产生和建筑认证等主题相关的条款。世邦魏理仕（CBRE）最近的研究表明，绿色租赁涵盖了一系列令人满意的特征，但报告和披露是最重要的。
最终，绿色租赁合同要求双方关注可持续性，并相互支持以提高绩效，实现长期目标，并遵守即将出台的法规。
它们确保每一方都能在他们负责的物业领域承担责任，并增加双方审查绩效的透明度。
There has already been a significant uptake of green leases in Europe and the United States. This can be explained by greater legislation in Europe and large global organisations based in the US and Europe setting ambitious climate targets.
In Apac, there has been slower adoption. Organisations are still hesitant to implement these contractual obligations where they are not necessary.
Landlords do not want to deter potential tenants with additional requirements, and tenants do not want to risk increasing rents due to increased landlord commitments. However, with greater legislation coming into play, more targets being set, and ever-tightening requirements on building certifications, green leases are starting to become a more normal practice in Apac, particularly for landlords and those global corporates with headquarters in Europe and the US.
In a recent CBRE Apac Occupier Sentiment Survey, almost two in three organisations deemed green leases to be at least a high priority. And almost 20 per cent of organisations would seek a discount on rental values if green leases are not present, outright rejecting a proposal, or paying a premium if they are present.
Different organisations have different levels of sustainability ambitions and overall business requirements. Therefore, some clauses just might not be applicable or achievable for certain businesses, and so there is no “one size fits all” solution to green leases. This creates complexity when looking at green lease frameworks and, in the past, this has been another barrier to their implementation.
To help address this, certain organisations are laying out frameworks that can help clarify what clauses might be best for a particular business.
In Singapore, the BCA has developed a green lease toolkit to lay out the minimum standards for green leases locally.
More widely, Green Lease Leaders have established model language for green leases and the Better Buildings Partnership (BBP) have created a green lease leaders’ framework, customisable with clauses that are rated Light Green, Medium Green, or Dark Green.
Whatever the language, the intent remains to foster a truly collaborative and mutually beneficial relationship between landlord and occupier, helping both parties to realise sustainability impact and achieve meaningful goals.
Green leases can enhance property values, reduce costs, create stronger relationships between landlords and tenants, and enhance overall building experiences. By utilising available frameworks, engaging sustainability experts, and developing deeper relationships with landlords/occupiers, organisations can deliver significant improvements in sustainability and support a greener future for all.
