COP is the Conference of the Parties and is attended by countries that signed the United Nations Framework Convention on Climate Change (UNFCCC) - a treaty agreed in 1994.
The 2021 meeting was the 26th meeting which is why it's called COP26.
At COP26 a newly established Glasgow Financial Alliance was announced for Net Zero carbon emissions of $130 trillion of private capital to accelerate the transition to a net-zero carbon economy.
The private sector is now under more intense scrutiny from both clients and institutional investors on ensuring net-zero commitments are robust and legitimate.
There are new requirements for all listed companies in the UK to produce net-zero transition plans by 2023.
To meet the needs of the present without compromising the ability of future generations to meet their own needs.
Key principles were also set out within the Brundtland Commission Report, Our Common Future 1987 which identified the need for sustainable development based around environmental protection, economic growth and social equity. It called for conservation of the environment and resources by gradually changing the ways in which we develop and use technologies.
What are the key principles of sustainability?
Social - Building healthy communities with sufficient numbers and range of buildings.
Economical - Build strong, responsive, competitive economies ensuring sufficient land and right types.
Environmental: - Contributing towards the protection and enhancement of our natural, built and historic environment.
What are the core principles of Planning and Decision making around sustainability?
Creative processes should be used not just scrutiny.
Proactive steps should be taken to achieve sustainable development.
Secure the development of high quality built assets.
Account for the character of the surrounding area.
Support a climate-resilient and low-carbon economy.
Conserve & enhance natural environment and reduce pollution.
Encourage use of brownfield sites.
Conserve heritage.
Maximise use of public transport, cycling and walking.
Support health, social and cultural well-being.
What are the most common environmental issues experienced on construction sites?
Risks of Water Pollution.
Air and Noise Pollution.
High Energy Consumption and carbon emissions.
Risk of land contamination.
Damage to wild habitats.
High Wastage production into landfill.
Release of dangerous gases and chemicals.
What are the key pieces of legislation that affect sustainability in construction?
Agricultural Land Act – Enables land to be acquired for a particular purpose for example to control pests and weeds, for use as woodlands or to support agricultural activities.
Building Act – This is the primary piece of UK Legislation that enables the Building Regulations to be enforced. This is to assist in the conservation of fuel and power, to prevent waste, misuse or contamination of water and to ensure those in and around buildings are kept safe.
Clean Air Act – This legislation provides local authorities within England to introduce measures in order to control air pollution.
Climate Change Act – This is a legally binding framework to tackle climate change. It imposed targets to cut greenhouse emissions compared with 1990 levels 34% by 2020 and 80% by 2050.
What are the Key Building Regulations that relate to sustainability in construction?
Building Regulations Part L — Conservation of Fuel and Power.
Energy Performance of Buildings Regulations.
Requires that EPC's are produced for dwellings and non-dwellings.
Quantifies energy efficiency of buildings.
Required when buildings are built, sold or rented.
Commercial buildings over 500 sqm. and frequented by the public need to display a display energy certificate (DEC) based on actual energy used.
What are the different forms of taxation relating to sustainability?
Landfill Tax which is an environmental tax payable in addition to landfill rates charged by private disposal companies.
The tax was introduced as a means to encourage alternative methods of disposal such as recycling.
The tax is charged by weight at varying rates depending on whether the waste is inert or active.
What different code of practice are you aware of for measuring sustainability?
BREEAM (Life Cycle Assessment).
Sets best practice standards for the environmental performance of buildings through specification, design, construction and operation.
BREEAM Stands for the Building Research Establishment Environmental Assessment Method.
The assessment is undertaken by a licensed assessor based on energy, land & ecology, water, health & wellbeing, pollution, materials and waste and management.
BREEAM applies to new and refurbishment projects, domestic and non-domestic. Rating are: Outsanding, Excellent, Very Good, Good, Pass, Unclassified.
SKA Ratings - An RICS Environmental assessment method for non-domestic fit outs such as office refurbishments. The scheme assesses fit out projects against a set of sustainability good practice criteria, known as Good Practice Measures (GPM). SKA can act as an alternative to BREEAM which have higher costs in comparison.
LEED (Life Cycle Assessment). LEED stands for Leadership in Energy and Environmental Design. It is a USA equivalent of BREEAM. Ratings are:- LEED Certified,Silver, Gold, Platinum. This method reviews embodied aspects of carbon emissions as well as life cycle assessment during construction and operation.
What procedures does your firm implement to promote sustainability?
Recycling of cardboard, paper and plastics.
