Assessment, design/simulation and post-construction monitoring.
The idea is to first identify the problem (which is pertinent to the location you are designing for), then you have to design solutions and simulate or compute their effects (iterative process to select the optimum design) then you have to monitor the design after construction to ensure that you attain the design values.
Everything humans require for their survival and well-being depends (directly or indirectly) on the natural environment. The concept of sustainable development has drawn considerable attention over the past 50 years but discussions of definition, scope, and possible means of realization have proved quite controversial. More recently, so we might better understand the consequences of our actions, a systems-based approach that elucidates the interactions among society, environment, and economy—aka the "Triple Bottom Line", "People–Planet–Profit", or "Three Pillars" framework—has gained credence. Here as in many other walks of life, learning before, during, and after an intervention can power a logical and practicable process for implementing environmental sustainability.
Similar to some of the ideas already presented, the forestry industry, US Forest Service used approaches including identifying Best Management Practices (BMPs), Soil and Water Conservation Practices (SWCPs), and Forest Land and Resource Management Plans to address resource management needs to protect and conserve water quality, soils, habitats, sustainable forestry and resource management. Many examples of State Forestry BMPs and National Forest Plans exist and available on the internet. The questions most often asked relative to BMPs were Did we do what we said we would do (ie, implement correctly), Did they do what they were supposed to do (ie, monitor results), Are they valid (appropriate, need adjustment, confirmed by appropriate studies or research)? I uploaded our SWCPs effort for the Southern National Forests in my Researchgate (~2004), and it goes into more specific detail, linking practices to various laws, regulations, etc. BMPs are designed to be an iterative process, implement, monitor, adjust when appropriate.
If we are talking about implementing change within an organization, upsetting the status quo to the point where there is recognition of how important change is must be done. A process I like to discuss with students and organizations is the change process itself as described by Bob Dopplet. He uses the idea of a "Wheel of Change" to show how Sustainability Blunders can be overcome.
Yes, the implementation process can be named, and the process can be reduced to 3 phases.
But before I go into that, environmental sustainability is a subset of the larger issue. Sustainability encompasses far more than that - I'm going to include social and economic sustainability simultaneously, because otherwise, it's like you're only asking about the 'heads' side of a coin.
Implementation is quite a bit different than monitoring. Economists act as system managers, and use indicators for monitoring and control. Engineers act as system designers, and use units of measure for prediction and optimization. Implementation relies far more on the engineer's process than the economist's process. Sustainable Development can be thought of as 'Relative Sustainability' - making the community 'more' sustainable. I think the process of implementation requires using 'Absolute Sustainability' - making the community 'be' sustainable.
Phase 1 is to define your terms. Sustainability is the ability of the people of a community to be able to meet all of their needs using the resources and ecological services of the land/air/water that they act as the stewards of, and the skills of the population, in perpetuity (or at the very least, beyond any rational planning horizon). Needs are universal aspects of human nature, but the boundary of those needs may be very specific to a population. Here in Canada, we think we have food security, so food may be considered a need, but perhaps only if it isn't imported from 'away'. And each community would have unique indicators of unmet needs - malnutrition for a hunting community may mean not having access to wild game. The community would have to provide a list of the needs they are going to measure, the boundaries of those needs, and the symptoms of unmet needs.
Phase 2 is to collect the data based on the definitions. All of the communities in the nation (as the 'community of communities') would have to decide on those lists, and then the population sampled, using a combination of time use study, needs assessment, and ecological footprint evaluation. The results would be used to establish the potential and actualized quality of life within the communities. Communities with similar results would be aggregated to have planning scales that would maximize quality of life.
Phase 3 is to use the data to guide planning and design. Everything that is being engineered can be checked to determine how it affects time use, needs satisfaction, and ecological impacts, together. If it can be shown that all people can have all of their needs met in 24h/d/ca or less, while considering the time costs associated with using resources that will become exhausted in a relatively short time scale (say 100 to 200 years), then the community would have Sustainability in an Absolute sense. Development initiatives would then try to reduce the time required for people to meet needs, so that more time is available for other purposes (such as popping out to the pub, or getting more education, or selling one's surplus time). Growth would be a byproduct of getting better at being sustainable, rather than trying to do things the other way around.
Environmental sustainability can be achieved through eleminating poverty from society, promoting equity and peace and situational technological implications
Process for implementation of environmental sustainability will vary depending upon the sector. In which sector are you looking for the implemention? Your answer will help in narrowing the responses from RG community.
Un proceso sencillo en las empresas es el promovido por las normas ISO 14000. Pero no deben ser una camisa de fuerza, se debe adecuar a las necesidades y características de las empresas. Por ello, los pasos serían los siguientes:
1. Conciencia ambiental de los propietarios y directivos.
2. Lograr que todo el personal participe activamente en el proceso ambiental
3. Planear todas las compras y cambios que deben hacerse al interior de la empresa para volverla sostenible, desde los aspectos: económico, ambiental y social
...you will find on my profile several papers on corporate sustainability management, sustainable business models and implementation of sustainability strategies, maybe that helps?
