Business managers have adopted strategies that take care of organizational goals and objectives and their stakeholders, at the same time sustaining, protecting natural and human resources for the survival of a corporate in the short run and in the long run.

Sustainable development
Sustainable development covers a wide area ranging from protection of the environment, micro and macro economic growth and development, and social justice in terms of distribution of natural resources. Therefore sustainable development is where the use of natural resources, investments directing , new technology introduction and defining human needs direction and aspirations for long term gain of the societal growth. The concept of sustainable development covers area of politics, economics, law, environment science, business management, and management. Like democracy, justice, fairness, and other societal concepts it is difficult to find definition (Wilson, 2003). From the literature available, research shows that the issues of sustainable cannot be left to the governments (Oxford university press, 1987).
Sustainable development has contributed to corporate sustainability through helping companies identify areas to focus on, which include environment, economic performance and social. It also provides social goals for corporation, governments and other groupings.
Social responsibility

Business organizations have adopted various ethical policies because they believe in showing the neighborhood their moral responsibility and in the process they have increased their sales.
Corporate social responsibility like any other concept is to be discussed broad terms. The idea of corporate social responsibility was introduced in 1973 when it was introduced in American corporations. Its basic premises of ethical obligation have made managers and shareholders to own self interest in business transactions. Every business manager who incurs business transactions will put the society goals and aspiration in the front.
Corporate social responsibility revolves around four basic theories which will include social contract theory (contractual relation), social justice theory (equitable distribution of resources), rights theory rights of community where the company is operating) and deontological theory.
Social contract theory: This theory assumes that there are a number of contracts both explicit and implicit between individuals, organizations, and institutions. Social contracts evolve around whims of trust and are made in harmony.
Corporations are assumed to business world by entering into contracts with the society in exchange for resources and acceptance to operate without interruption.
Social Justice Theory: This examines the fairness in distribution of societal goods and services.
The theory puts forward arguments that societies are considered, by way of distributing of social goods. Corporate managers, have a responsibility in ensuring these goods have been appropriately being shared in the society.
Rights theory: This theory deals concentrate in rights of various members of the society like human rights and other rights. Corporate managers should not interfere with property rights and human rights of members of the society.

Deontological theory: This theory assumes that everybody is equal and should treated with respect and everybody has a moral duty to that effect. This belief is for everyone, including corporate managers, shareholders and other stakeholder. Corporate social responsibility gives reasons why managers.
Stakeholder’s theory
The brain behind the stakeholders’ theory of the firm is R. Edward Freeman, in his book 1984, Strategic management: A stakeholder Approach.
He defined stakeholders as “any group or individual who can affect or is affected by the achievement of the organization’s objectives (Freeman, 1984). The aim of this theory is to assist corporate identify stakeholders and strengthen relationship with them and other external groups this will make the remain competitive advantage and relevant. Stakeholders will include shareholders, employees, customers and suppliers. It is difficult identify others because there is no clear formulae for defining stakeholders (Wilson, 2003). However, since advertisement is making the world a small village, everybody is becoming a stakeholder depending on a number of factors. The factors to be considered in defining qualifying one as a stakeholder may include global impacts of an industry a “such as climate change or cultural changes due to marketing and advertising.
Examples of social responsibility includes:-
- Stakeholder
- Example

- Creation of jobs and development of infrastructure
- Government
- Job opportunities for citizens and taxes arise from business transactions.
- Supplier

Responsibility is a duty for one to act in a responsible way. There is relationship between shareholder and management which is and agency law thus agency theory. Management acts as agents’ and the shareholders acts the principal’s (Wilson, 2003). Shareholders entrust their capital in management in return for accountability and return on capital.

Accountability does not only relate to the relation between managers and shareholders but also to other stake holder as identified by Freeman in his book. Proponents of stakeholders theory argued that businesses are authority to exist for good behaviors.

The journey to corporate sustainability is bumpy, rough, tough and noisy for any manager to proud himself for having reached the far end of the path must face the following challenges and take advantage of underlying opportunities.

Democracy and Governance: managers and decision makers face challenges of embracing democracy and corporate governance while trying to pursue sustainability initiatives. Benn and Dunphy have argued that policies impact on innovative sustainability initiatives while in other cases they become partners in the sustainability process.

Financial constrains: in implanting corporate sustainability manager face challenges of financial constrain Technology Strategy: Technology issues that organizations need to consider when innovating towards sustainability pose challenges to policy makers. The advent of digital technologies has impacted on sustainability outcomes. Sustainability issues should be incorporated into the organization through learning methods.
