Technologies for Getting to Zero Emissions by 2060
Question: How fast are technologies to address climate change developing, particularly with regard to electric vehicles?
GenerallyEclectic looked at Canada's Greenhouse Gas emissions and found that in 2012, road transportation accounted for 19.0 percent of Canada's emissions, and emissions from road transportation had increased by 36.8 percent over the period 1990 to 2012. Clearly, the development of electric vehicles is an essential element in getting emissions to zero by 2060.
To answer the question on how fast technologies were developing, GenerallyEclectic looked at articles in Science Daily on electric vehicles for the previous eighteen months, which at the time of writing was December 1, 2018 to May 31, 2020. GenerallyEclectic found 44 articles, many promising technological development with the capable of transforming electric vehices. Overall, the future is promising. Titles, summaries and links to the relevant articles are provided, so you can make your own judgments.
The summary here is limited to Science Daily findings, which are in turn determined by Science Daily's methodology, which is outlined at About Science Daily. To the extent that Science Daily undoubtedly missed some technological developments, this summary under-reports developments.
