Climate Change Background

The subject of Climate Change Sustainability is a complex subject but one that we should all come to understand, because of its influence on our future.

Commonly we talk about Climate Change Adaptation and Climate Change Mitigation. We also talk about the reduction in fossil fuel energy and replacement with renewable energy, minimising or eliminating altogether carbon footprints. Often Adaptation and Mitigation are treated as totally separate things. Adaptation tries to accommodation a change in climate, assuming that to some extent, it is going to happen. Mitigation is about reducing the risk of it happening. Reducing the use of energy can be as a result of Adaptation, but it can also be as a result of Mitigation. Changing from fossil fuel energy to renewable energy is more to do with Mitigation than Adaptation. It is worth referring to David Mackay's 'Sustainable Energy - without the hot air' (UIT Cambridge England, 2009, ISBN 978-0-09544529-3-3), available to download free.

The majority of people within the West Midlands Construction Industry will be aware that there has been considerable research into Climate Change Sustainability. As a result, new methods and new materials have been developed and this will continue. Many of the new methods and new materials are at the “Model T Ford” stage, although this is not always the case. Where we are in the early stages of development, where maximum efficiencies have not yet been achieved, it would be easy to reject them because what has been developed is not cost effective. That could be a mistake and care has to be taken.

The Kyoto Protocol has the goal of achieving stabilisation of greenhouse concentrations in the atmosphere at a level that would prevent dangerous interference with the climate system. The United Kingdom passed the Climate Change Act in 2008, with a target of 80% reduction in carbon dioxide emissions by 2050, using a 1990 base. The construction industry is working towards this.

Relevant are the UK Government Sustainable Development Strategy ('Securing the Future' - 2005) and the UK Government 'Strategy for Sustainable Construction' (June 2008). The latter covers the following headings:

 HeadingsOverarching Target
The 'Means'Procurement

To achieve improved whole life value through the promotion of best practice construction procurement and supply side integration, by encouraging the adoption of the Construction Commitments in both the public and private sectors and
throughout the supply chain.

Design

The overall objective of good design is to ensure that buildings, infrastructure, public spaces and places are buildable, fit for purpose, resource effcient, sustainable,
resilient, adaptable and attractive. Good design is synonymous with sustainable construction. Our aim is to achieve greater use of design quality assessment tools relevant to buildings, infrastructure, public spaces and places.

Innovation

To enhance the industry’s capacity to innovate and increase the sustainability of both the construction process and its resultant assets.

People

An increase in organisations committing to a planned approach to training (e.g. Skills Pledges; training plans; Investors in People or other business support tools;
Continuous Professional Development (CPD); life long learning). Reduce the incidence rate of fatal and major injury accidents  by 10% year on year from 2000 levels.

Better RegulationA 25% reduction in the administrative burdens affecting the private and third sectors, a 30% reduction in those affecting the public sector by 2010.
The 'Ends'Climate Change MitigationReducing total UK carbon dioxide (CO2) emissions by at least
60% on 1990 levels by 2050 and by at least 26% by 2020.
Within this, Government has already set out its policy that
new homes will be zero carbon from 2016, and an ambition
that new schools, public sector non-domestic buildings and
other non-domestic buildings will be zero carbon from 2016,
2018 and 2019 respectively.
Climate Change AdaptationTo develop a robust approach to adaptation to climate change,
shared across Government.
WaterTo assist with the Future Water vision to reduce per capita
consumption of water in the home through cost effective
measures, to an average of 130 litres per person per day by
2030, or possibly even 120 litres per person per day depending
on new technological developments and innovation.
BiodiversityThat the conservation and enhancement of biodiversity within
and around construction sites is considered throughout all
stages of a development.
WasteBy 2012, a 50% reduction of construction, demolition and
excavation waste to landfll compared to 2008.
MaterialsThat the materials used in construction have the least
environmental and social impact as is feasible both socially
and economically.

People need to understand how they may help to achieve the 80% reduction (Kyoto protocol), bearing in mind that we all, in one way or another, will be affected by legislation in the coming years, as well as by increasing energy prices.
