According to the Taiwan Climate Change Projection Information and Adaptation Knowledge Platform (TCCIP) the number of days that record above 36 degree Celsius in the plains of Taiwan can go from less than 1 day a year in 2021 to 48.1 days in 2100 if the global temperature rise isn't kept under 1.5 degree Celsius, if it is kept under 1.5 degree Celsius there would be 6.6 days a years with such temperatures. The summers could also be extended by the end of the century from 80 days to 210 days, the winters will become shorter with 0 to 50 days compared to 70 days in 2021.{{Cite web|title=Climate change may cost Taiwan dearly without action: experts - Focus Taiwan|url=https://focustaiwan.tw/sci-tech/202108100019|access-date=2021-08-12|website=focustaiwan.tw|language=zh-Hant-TW|archive-date=2021-08-11|archive-url=https://web.archive.org/web/20210811205126/https://focustaiwan.tw/sci-tech/202108100019|url-status=live}} The summer of 2020 has been recorded as having the hottest weather ever in Taiwan.

= Sea level rise =

In a report that Greenpeace Taiwan published in August 2020, it was reported that the sea around Taiwan is rising at twice the rate of the global sea level rise. They said 6 municipalities are in danger of sea level rise and storm surges which accounts for 70% of the population. Places like the Presidential Office Building in Taipei, Songshan Airport, parts of Kaohsiung would be flooded and Tainan would see the biggest damage due to flooding.

The government of Taiwan has invested in the wind turbine industry, Taiwan had the 8th biggest offshore wind market in the world in 2019.

== Pricing of carbon ==

Taiwan does not currently have any form of carbon tax. In 2009, the Chung-Hua Institution for Economic Research (CIER), which had been commissioned by the government to advise on its plan to overhaul the nation's taxes, recommended a levy of {{NTD|2,000|link=yes}} ({{US$|61.8}}, £37.6) per tonne of CO2 emissions.{{cite web |last=Chan |first=Yvonne |date=20 October 2009 |title=Taiwan plans taxes for energy and CO2 emissions by 2011 |url=http://www.businessgreen.com/business-green/news/2251588/taiwan-plans-taxes-energy-co2 |url-status=live |archive-url=https://web.archive.org/web/20091024142437/http://www.businessgreen.com/business-green/news/2251588/taiwan-plans-taxes-energy-co2 |archive-date=24 October 2009 |access-date=5 August 2010 |publisher=Businessgreen.}} As a result, vice finance minister Chang Sheng-ho announced a plan for a carbon tax in starting 2011, with the revenues funding low-income families and public transport.{{cite web |date=19 October 2009 |title=Taiwan plans energy tax starting in 2011 |url=http://www.earthtimes.org/articles/news/290768,taiwan-plans-energy-tax-starting-in-2011.html |url-status=live |archive-url=https://web.archive.org/web/20110515101415/http://www.earthtimes.org/articles/news/290768,taiwan-plans-energy-tax-starting-in-2011.html |archive-date=15 May 2011 |access-date=5 August 2010 |work=Earth Times}} However, Premier Wu Den-yih opposed implementing the tax, arguing it would increase public suffering during the then ongoing recession.{{cite news |last1=Jehng-jung |first1=Kao |date=26 October 2009 |title=The carbon tax proposal needs more airtime - Taipei Times |work=www.taipeitimes.com |url=https://www.taipeitimes.com/News/editorials/archives/2009/10/26/2003456877 |access-date=19 September 2022 |quote=this decision was instantly rejected by Premier Wu Den-yih (吳敦義) |archive-date=20 September 2022 |archive-url=https://web.archive.org/web/20220920171137/https://www.taipeitimes.com/News/editorials/archives/2009/10/26/2003456877 |url-status=live }}{{cite news |date=31 December 2009 |title=Carbon-reduction will benefit the economy in the long run |language=en |work=Taiwan Today |url=https://taiwantoday.tw/news.php?unit=2&post=851 |access-date=19 September 2022 |quote=Premier Wu Den-yih has also said “the stomach must be taken care of first.” |archive-date=20 September 2022 |archive-url=https://web.archive.org/web/20220920172529/https://taiwantoday.tw/news.php?unit=2&post=851 |url-status=live }} The carbon tax was never implemented.

As opposed to the commonly adopted carbon tax, Taiwan's Climate Change Response Act has proposed implementation of a carbon fee.

Society and culture

= Public perception =

According to a survey that the RSPRC conducted in April 2020, 85% of Taiwanese said that they experienced the effects of climate change on some level. The survey also found that acceleration of energy transition and reduction in carbon was ranked in third place with 38.7% when asked what the government long terms priorities should be. There is bipartisan support under supporters of the Pan-Blue camp (76.2%) and the Pan-Green camp (84%) for a proactive promotion of an energy transition. 78.5% of the respondents supported the governments targets for 2025 to have 20% of renewable energy in 2025. Respondents gave 3.83 out of 7 points for how fair the energy transition is, they gave 3.74 out of 7 points to how well planned the energy transition is and they gave 4.32 out of 7 points on how urgent the government acted on it. A total of 44.7% are supportive to phase out fossil fuels, 43.7% were against phasing out fossil fuels. Academics and experts were the most trusted when talking about energy information (59.3%), environmental groups came second (37.6%). 59.8% of respondents said that businesses should be required to have obligations with the energy transition if they get stimulus from the government to help them through COVID-19, 77.2% of respondents wanted that they did the same for airlines.
