"21. [The World Heritage Committee] (u)rges States Parties, with the support of the World Heritage Centre and the Advisory Bodies, to:
a) Incorporate well-designed buffer zones based on a holistic understanding of natural as well as human induced factors affecting the property, supported by reinforcing relevant legal, policy, awareness and incentive mechanisms, into new nominations and where appropriate into existing properties to ensure enhanced protection of World Heritage properties,
b) Place particular emphasis on strategic environmental assessment and impact assessments for potential projects within buffer zones to avoid, negative impacts on OUV from developments and activities in these zones,
c) Develop buffer zone protection and management regimes that optimize the capture and sharing of benefits to communities to support the aspirations of the 2015 Policy for the integration of a Sustainable Development Perspective into the processes of the World Heritage Convention,
d) Ensure buffer zones are supported by appropriate protection and management regimes in line with the property’s OUV, that build connectivity with the wider setting in cultural, environmental and landscape terms."

9. "(…) appropriate balance, integration and harmonization between the protection of OUV and the pursuit of sustainable development objectives will include (…) provisions for the systematic assessment of environmental, social, and economic impacts of all proposed developments, as well as effective monitoring through continuity in data collection against agreed indicators."

Paragraph 110

“An effective management system depends on the type, characteristics and needs of the nominated property and its cultural and natural context. Management systems may vary according to different cultural perspectives, the resources available and other factors. They may incorporate traditional practices, existing urban or regional planning instruments, and other planning control mechanisms, both formal and informal. Impact assessments for proposed interventions are essential for all World Heritage properties.”

Paragraph 172

“The World Heritage Committee invites the States Parties to the Convention to inform the Committee, through the Secretariat, of their intention to undertake or to authorize in an area protected under the Convention major restorations or new constructions which may affect the Outstanding Universal Value of the property.  Notice should be given as soon as possible (…) and before making any decisions that would be difficult to reverse, so that the Committee may assist in seeking appropriate solutions to ensure that the Outstanding Universal Value of the property is fully preserved.”

11. "[The World Heritage Committee] taking note of the benefits to States Parties of systematically utilizing Heritage Impact Assessments (HIAs) and Environmental Impact Assessments (EIAs) in the review of development projects, encourages States Parties to integrate the EIA/HIA processes into legislation, planning mechanisms and management plans, and reiterates its recommendation to States Parties to use these tools in assessing projects, including assessment of cumulative impacts, as early as possible and before any final decision is taken, and, taking into account the need for capacity-building in this regard, requests the States Parties to contribute financially and technically towards the development of further guidance regarding EIA/HIA implementation, by the Advisory Bodies and the World Heritage Centre, based on case studies and field experience."

"30. [The World Heritage Committee] notes that the pressures on historic urban areas arising from inappropriate or inconsistent development controls, rapid, uncontrolled and planned development, including large development projects, additions that are incompatible in their volume, mass tourism, as well as the accumulated impact of incremental changes have continued within numerous World Heritage properties and in their buffer zones and settings, and considers that these present potential and actual major threats to the Outstanding Universal Value (OUV) of properties, including their integrity and authenticity, as well as increasing their vulnerability to disasters, including those resulting from climate change;
(…)
34. [The World Heritage Committee] (s)tresses the importance of carrying out Heritage Impact Assessments to evaluate and thereby avoid or manage potential threats to the OUV of the property arising from new urban development projects."

37. "[The World Heritage Committee] stresses the necessity for HIAs and Environmental Impact Assessments (EIAs) to be proportionate to the scope and scale of projects, with simpler assessments being undertaken for smaller projects and Strategic Environmental Assessments (SEAs) for very large projects, and the necessity for assessments to be undertaken in a timely fashion and submitted to the World Heritage Centre for review by the Advisory Bodies (…)."
