'Based on the provided context, the latest research on climate change innovation reveals several important findings:
1. Innovation in response to climate change: A study examined how innovation responds to climate change by analyzing a panel dataset of 70 countries. The study found that the number of climate-change-related innovations is positively correlated with increasing levels of carbon dioxide emissions from gas and liquid fuels, mainly from natural gases and petroleum. However, it is negatively correlated with increases in carbon dioxide emissions from solid fuel consumption, mainly from coal, and other greenhouse gas emissions. The research also highlighted that government investment does not always influence decisions to develop and patent climate technologies. This study contributes to the environmental innovation literature by providing insights on how innovation reacts to changes in major climate change factors.
2. Climate tech funding and attention: During the period of 2010-2022, outside of the US, China, EU, and India, only 8% of total climate venture capital activity came from the rest of the world. This concentration of funding and attention in specific regions may be hindering the reach of climate tech solutions to low-income communities and developing countries, which are already feeling the effects of climate change but lack the necessary resources to address them effectively.
3. Research funding allocation: A study from the University of Sussex Business School analyzed research funding for climate and energy research from 1990 to 2020. The research found that 36% of funding was allocated to climate adaptation, while 28% went to studying how to clean up the energy system. Other significant shares of funding were allocated to transport and mobility (13%), geoengineering (12%), and industrial decarbonization (11%). The majority of the funding went to researchers in wealthy, Western countries, which may not be the most vulnerable to the immediate impacts of climate change.
