Why climate change measures do not make sense, and how we can fix them

While the current norm is to assume that pursuing renewable energy is the most effect measure against climate change, there may be more to the story.

If asked to list climate change solutions, many of us would start with renewable energy. It is obviously a key one given the use of fossil fuels for energy is the largest contributor to greenhouse gas emissions globaly. However, beyond that we may soon get stuck, particularly if asked to focus on how much specific technologies or social changes can potentially contribute to decarbonising the economy; harder still if trying to identify a group of solutions which will be enough to achieve the goals of the Paris Agreement.

Many research providers and standard-setting bodies have been working on climate measures and disclosures for investors with mixed success. A key gap is that no current standard, when considered across a portfolio of listed-equity investments, covers the essential questions of how much a contribution can different solutions make and whether collectively they are enough.

Climate change is unquestionably a complex issue, more so when considered alongside the speed and scale of change required to prevent the worst impacts of this environmental crisis unfolding. It is understandable then, that attempts to measure the implications of this issue for an investment context will also carry a degree of complexity and that it would be impossible for any single metric to capture this complexity.
