more ethically. The index acts as an incentive for firms to improve their environmental footprint to attract more shareholders. Later in 2000, the United Nations introduced the Millennium Development Goal scheme which sought to promote a sustainable framework for large multinational corporations and countries to follow to improve the environmental impact of financial investments. This framework facilitated the development of the United Nations Sustainable Development Goal scheme in 2015, which aimed to increase funding environmentally responsible investments in developing nations. Funding was targeted to improve areas such as primary education, gender equality, maternal health, and nutrition, with the overall goal of creating beneficial national relationships to decrease the ecological footprint of developing economies. Implementation of these frameworks has promoted greater participation and accountability of corporate environmental sustainability, with over 230 of the largest global firms reporting their sustainability metrics to the United Nations. The United Nations Environment Program (UNEP) has had a detailed history in providing infrastructure to improve the environmental effects of financial investments. In 2004, the institute provided training on responsible environmental credit budgeting and management for Eastern European nations. Following the Global Financial Crisis beginning in 2007, the UNEP provided substantial support for future sustainable investment choices for economies such as Greece which were impacted severely. The Portfolio Decarbonisation Coalition established in 2014 is a significantly notable initiative in the history of environmental finance as it aims to establish an economy that is not dependent on investments with large carbon footprints. This goal is achieved through large-scale stakeholder reinvestment and securing long-term, responsible, investment commitments. Most recently, the UNEP has recommended OECD nations to align investment strategies alongside the objectives of the Paris Agreement, to improve long-term investments with significant ecological effects. In 2008 the Climate Change Act enacted by the UK Government established a framework to limit greenhouse gasses and carbon emissions through a budgeting scheme, which motivated firms and businesses to reduce their carbon output for a financial reward. Specifically, by 2050 it seeks to reduce carbon emissions by 80% compared to levels in 1980. The Act seeks to achieve this goal by reviewing carbon budgeting schemes such emission trading credits, every 5 years to continually reassess and recalibrate relevant policies. The cost of reaching the 2050 goal has been estimated at approximately 1.5% of GDP, although the positive environmental impact of reducing carbon footprint and increased in investment into the renewable energy sector will
