Zero Emissions Day On September 21


CLC’s purpose is to help its members to develop and innovate more climate-friendly products and services, and so to increase their positive carbon handprint. On Zero Emissions Day, on September 21, we highlight these solutions.

Everyday choices made by ordinary people hold the key to our efforts to reduce emissions and find more sustainable solutions. Recently published IPCC Working Group III report “Climate Change 2022: Mitigation of climate change” highlights that:

    • We need immediate and deep emission reductions across all sectors for limiting the global warming to 1.5°C
    • Demand-side measures (changes in infrastructure use, end-use technology adoption, and socio-cultural and behavioural change) and new ways of enduseservice provision can reduce global GHG emissions inend-use sectors by 40-70% by 2050

Zero Emissions Day started in Nova Scotia, Canada, 2008. CLC began organising the event in Finland in 2017. Zero Emissions Day has been designed to give the world a break from fossil fuels and to raise awareness about the harm caused by carbon emissions. The goal is to engage people towards more climate-friendly choices in their personal life.

In 2023 the focus will be on the High School Students’ Zero Emissions Day challenge to businesses. In addition, two events will be organized: one in Lempäälä and another one for students in the Otaniemi Upper Secondary School.

CLC member organisations are encouraged to report their own climate actions to the Student Challenge for businesses.


A group of students from Espoo, Lempäälä and Tampere are challenging companies to communicate their most positive climate actions of the year on Zero Emissions Day on 21 September 2023.

Climate action can be related to reducing own emissions of businesses, cooperating with other actors to reduce emissions or developing and launching a new climate-friendly product or service. The idea is that it is a concrete measure or project that has already been implemented.

Companies should provide information on their climate action by describing it in about ten sentences in the following Google Forms form by 12 September. The description can be accompanied by a link to the company’s website, which may contain more detailed information about the company and its environmental responsibility.

We also encourage companies to communicate their climate action on social media on 21 September using the tag #zeroemissionsday. Climate Warriors from Lempäälä and Tampere will also highlight companies’ climate actions on social media.

On 21 September, high school students will learn about the climate actions of companies and vote for the best one. All upper secondary school students in Finland can participate in the voting. The winner will have the Vote of the Youth: Climate Action of the Year 2023 diploma and an honour.

The campaign’s partners, including CLC, will communicate the campaign and highlight the most interesting corporate climate actions in their own channels.


During the Zero Emissions Day the parish of Lempäälä will organize an event with several actors from Lempäälä, where the activities and solutions of local actors from individual measures to larger entities will be presented. The event will take place in the Ideapark shopping center. The event includes presentations, a panel discussion and an opportunity for audience questions. Actors participating in the event are: the parish of Lempäälä, CLC, Climate warriors of Lempäälä High School, Lempäälä Lämpö Oy, Lempäälä Municipality, Tampere University and Ideapark Oy. The aim of the event is to raise the awareness of citizens, decision-makers and parishioners about environmental issues and emission reduction opportunities, to disseminate information on solutions and activities being developed, to promote the possibility of climate partnerships and to strengthen the effectiveness of working together. 


Otaniemi Upper Secondary School will organize an event for students. The event will be streamed on the Youtube channel of Lukema.
